Laser Printer Precautions because the GQ-3500 is a laser printer using electrophotographic technology, certain precautions are necessary to ensure safe and efficient operation. The following list of precautions applies whenever you open the printer case. Even if you are familiar with other types of printers, be sure to familiarize yourself with these precautions. 1. Be careful not to touch the fusing unit, which is marked by a CAUTION: HOT SURFACE label. 2.
Chapter 1 Setting Up To set up your GQ3500 printer simply follow the steps in this chapter. 1 Unpacking the Printer Carefully unpack the carton. At the top of the carton is a box containing several printer components. Beneath that box is the printer itself, which is protected by white foam packing material. After you take out the inner box where you found this manual, do not open the smaller boxes that are inside of it. Instead, carefully remove the printer from the large carton.
Also keep the following tips in mind: . Place the printer on a flat, stable surface. . Choose a place that is clean and free from excessive heat (including direct sunlight), moisture, and dust. . Use a grounded outlet - one that has three holes to match the power plug on the printer. Don’t use an adapter plug. l . Avoid sockets on the same circuits with large motors or other appliances that might disturb the power supply.
WARNING Do not expose the drum cartridge to any light brighter than normal room light, and do not expose it to room light for more than five minutes. Leave it boxed until you have read over the next few pages and know how to install it. Also, do not touch the surface of the drum or let it rest on any hard surface that might scratch it. Open the drum cartridge box and pull out the plastic container, as shown in Figure 1-2.
Because the top of the plastic container does not stay open by itself, put a small object on the top to hold it open, as indicated in Figure 1-4. Then remove the orange holder. It is needed only for transportation. Figure 1-4. The open container Place Now you are ready to install the drum cartridge. Follow these steps: 1. Lift up on the latch on the front of the printer and open the printer. (See Figure 1-5.) Figure 1-5.
2. Hold the drum cartridge by the two green tabs and lift it out of the plastic container. Then be sure that the drum is toward the right side of the printer, and lower the cartridge into the opening to the left of the block of white foam packing material (as shown in Figure 1-6). Figure 1-6. Installing the drum cartridge 3. Lower the cartridge into the printer until it fits into place. Then press the green tabs back to the horizontal position. 4.
Figure 1-7. Pressing the reset lever set lever 4 Installing the Toner Cartridge The toner cartridge must be installed in the developing unit (which is already in the printer). Follow these steps: 1. Remove the block of white packing material from the developing unit (to the right of the drum cartridge). 2. Next take the toner cartridge out of its box. Remove the take-up handle and the tape from the top of the cartridge. 3.
Caution Do not press on the top of the toner cartridge because toner may spill into the printer. Instead press on the edge of the cartridge as shown. If toner spills into the printer, remove it with a small vacuum cleaner. 4. On the bottom right side of the toner cartridge are two pins, one at each end. (See Figure 1-8.) Hold the toner cartridge vertically with the pins at the bottom and lower the pins into the notches in the developing unit. Then tilt the cartridge into place, as shown in Figure 1-9.
6. Attach the seal take-up handle to the small plastic shaft at the front of the toner cartridge. (See Figure 1-11.) Move the lever back and forth (in the direction of the arrows in Figure 1-11) until it won’t move any further with moderate pressure. (You will see red markings on the seal when you reach the end of it.) This step, which may take up to 40 back and forth movements of the handle, peels back the toner seal and releases the toner into the developer. Figure 1-11.
5 Installing the Paper Tray before you install the paper tray, remove all of the packing material, including any white foam and pieces of tape. Then follow these steps: 1. Push down the paper set lever until it clicks into place. (See Figure 1-12 for the location of the paper set lever.) 2. Hold the paper tray as shown in Figure 1-12. Notice that it is at an angle. Slide the plastic runners on either side of the paper tray into the black grooves inside the printer.
Figure 1-13. Paper set lever and guides Paper guides w &Maper set lever 2. Insert a stack of paper into the tray, making sure that the top of the stack does not cover the red mark on the inside of the paper tray. Push the paper in gently as far as it will go, as shown in Figure 1-14. (The paper will feed more easily if you fan it before you load it.) Figure 1-14. Loading paper Slide the paper guides together until they are both against the edges of the stack of paper. (See Figure 1-15.
Figure 1-15. Adjusting the paper guides 4. Set the paper exit path with the paper path selector at the bottom left of the front of the printer. Set the path for facedown delivery by turning the dial down as shown in Figure 1-16. With this setting the paper will exit at the top of the printer. Figure 1-16. Setting paper path When ejected facedown, the pages are stacked in the order in which they are printed. The other setting for paper delivery requires the use of the face-up output tray.
7 Turning On the Printer 1. before attaching the power cord, make sure the power switch on the left side of the printer (see Figure 1-17) is turned off. (It is off when the 0 side of the switch is pushed in.) 2. Attach the power cord at the back of the printer as shown in Figure 1-17. Then plug the power cord into a properly grounded outlet. Figure 1-17. Attaching the power cord - 3. Turn the power ON with the power switch.
Figure 1-18. The control panel From this panel you can control almost all the printer functions. ON LINE The ON LINE button switches the printer between the on line and off line states. In the on line state, the ON LINE light is on. This means that the printer can receive and print data (if the POWER and READY lights are also on). In the off line state, the ON LINE light is not on, nor is the READY light on. In this state, you can enter the SelecType mode, as explained in Chapter 3.
FUNCTION 2/PAPER FEED This button also has several uses: . Printing out any data received and ejecting the paper. . Feeding the paper during a printer self test. l Selecting details for each function in the SelecType mode. Note Because they have so many functions, these two buttons have two names each. This manual uses whichever name is appropriate to the operation being described.
SERVICE REQUIRED - Flashes when certain printer malfunctions are detected. The STATUS display shows the code for the specific malfunction. See Chapter 5 for full information on SERVICE REQUIRED messages. STATUS display The STATUS display shows many different messages. Some common status message codes are shown on the control panel for easy reference.
2. Press the FUNCTION 2 button to start the self test. The 1C message will flash until the page is ejected from the printer. You will see a sample of the printer’s characters like this one: !"#$%&I()*+,-./0123456789:;<=>?@ABCDEFGH !"#$%&I()*+,-./0123456789:;(=>?@ABCDEFGHI "#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJ #$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJK $%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKL %&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLM &I()*+,-./0123456789:; <=>?@ABCDEFGHIJKLMN lo*+,-.
Chapter 2 Starting Printing Now that you have set up your GQ-3500 and tested it to make sure it is working properly, you need to do three things before you start printing: l Set switches that change some of the printer’s settings to suit your individual needs . Connect the printer to your computer l Set up your application programs for the GQ-3500. It is best to read this entire chapter before you begin changing switch settings.
2. Make sure that the power to the printer is turned off and that no cable is connected from the printer to the computer. 3. Loosen the two knobs and pull the interface straight out as shown in Figure 2-2. Figure 2-2. Removing the interface Knob 4. - Locate the switches on the interface board. The two groups of DIP switches (see Figure 2-3) are labeled SW 1 and SW 2. Each of the individual switches also has a small number, from 1 to 8.
Setting the DIP switches Use the tip of a ballpoint pen or another small pointed object to turn the switches ON or OFF. Setting Switches This section first describes the main choices you have and then it tells you how to reset the appropriate switches. Choosing an operating mode The GQ-3500 has four operating modes: Page printer-gives access to all the printer’s capabilities, including such features as forms overlays, double-high and triple-high printing, and graphics primitives.
Table 2-1. Settings for operating mode 1-1 1-2 Automatic reprint when paper jams When a paper jam occurs, the page being printed is sometimes spoiled. If switch 1-3 is ON, the printer automatically reprints pages that jam. If this switch is OFF, the jammed page is not reprinted. Setting this switch ON may slow the printing speed because the printer’s memory buffer retains the data describing the page being printed until it has finished printing it.
Beeper When switch 1-8 is ON, the beeper tells you of errors and signals sent by the computer. You can silence the printer’s beeper by turning this switch OFF. Page orientation Most printing is done in the portrait (vertical) orientation. Set switch 2-1 OFF for portrait, ON for landscape (horizontal) orientation. Paper size The GQ-3500 offers several possible paper size settings: letter 03-l /2” x ll”), legal (8-l /2” x 149, half letter (8-l /2” x 5-l /2”), and three metric sizes: A4, A5, and B5.

Connecting the Printer to a Computer If you are using the GQ-3500’s standard parallel interface, you must use a shielded cable suitable for a Centronics compatible interface. 1. Be sure that the power to both the computer and printer are turned OFF. Plug the connector into the printer as shown in Figure 2-4. 2. Snap the retaining clips into place. Figure 2-4. Connecting the interface cable Some parallel cables have a ground wire.
Note Paper size and operating mode are the two most important settings you can make with DIP switches. Also, additional settings for the parallel interface are described in Appendix F and for the serial interface in the instructions packaged with the serial interface. Using the GQ-3500 with Application Programs Now that you’ve set up and tested the printer, you need to start using it with your application programs. Doing this is basically a fivestep process: 1.
Note The GQ-3500 will not print italics in any operating mode unless an italic or oblique font is available (from a font card or a user-defined font), and because of the high resolution of the GQ-3500, the LQ mode may slightly change the aspect ratio of some graphics. Putting printer codes in documents Some programs provide a way of placing complete printer commands in the text. These commands may or may not be visible on your screen.
3. Press the SHIFT button once. The status indicator on the control panel displays a blinking dot to show that the printer is in SelecType mode. In the SelecType mode, the left character in the STATUS indicator indicates the function and the right character indicates an option within that function. If you have set your DIP switches for letter size paper, the STATUS indicator displays 05 when you first enter SelecType.
3. After selecting the option you want, either exit SelecType or press the FUNCTION 1 button again to move to the next function. Repeat these steps until you have selected all the options you need. Exiting SelecType mode To exit SelecType mode, press the SHIFT button. The blinking dot at the bottom of the status indicator goes out. The printer remembers your selections until the power is turned off or until you change them.
Function 2: Orientation Prints in either portrait (vertical) or landscape (horizontal) orientation. option 0 1 Description NOR (normal), which is also called portrait orientation ROT (rotated), which is also called landscape orientation Function 3: Font Selection Selects the source of fonts as internal, IC card, or download. After setting this function, you can select an individual font with functions 4, 5 or 6. Remember that these can also be selected by software commands.
Function 6: Download Font Selects one of up to 8 user-defined fonts that can be downloaded to the GQ-3500 (function 3, option 2 must first be selected). Option 0-7 Description Selects a user-defined font numbered from 0 - 7 Function 7: Language Selects between 9 different language character sets. There are 12 characters that change depending on the country you choose. (See Appendix D.
Option 0 1 2 3 Description 1 /S” line spacing l/6” line spacing l/4” line spacing l/3” line spacing Function A: Font Style Selects either normal or bold printing. Option 0 1 Description Normal characters Bold characters SelecType with DIP Switches or Software Commands You can select many of the options available with SelecType by software commands (see Appendix A) or DIP switches (see Appendix 0.
Chapter 4 Paper With the GQ-3500 you can print on many different sizes and types of paper. The printer feeds most types automatically from the paper tray, while special ones -such as envelopes, labels, and overhead projector transparencies - should be fed individually for greater control. This chapter describes the paper delivery choices and how to select and load paper. Paper Delivery Choices The GQ-3500 can deliver paper facedown on top of the printer or face-up on the face-up output tray.
Figure 4-1. Installing the face-up tray Types of Paper Plain paper-The GQ-3500 automatically feeds 16- to 24-pound paper. This encompasses the normal papers found in an office, such as copier paper, memo sheets, and letterheads. If you hand-feed the paper or load it one sheet at a tune through the paper tray, you can use 16- to 34-pound paper. Special paper -You can use colored or three-hole punched paper in the GQ-3500 as long as it meets the weight limits given above.
Considerations in Selecting Paper The paper that you use with your GQ-3500 affects the quality of your printed output. The printed image is made up of many tiny dots of toner that are transferred to the paper. If the paper is rough, the edges of the letters become ragged because some of the dots fall into indentations on the paper, while others fall on the ridges. Therefore, the print quality will not be as good as that produced on a smooth paper.
Table 4-1. Standard paper sizes Size Dimensions Letter Legal Half Letter A4 (metric) A5 (metric) B5 (metric) 8-1Px 11” 8-l/2” x 14 5-l 12” x 8-l I2 21 Omm x 297mm 148mm x 21 Omm 182mm x 257mm Choosing a Standard Paper Size You will probably use one paper size most of the time. For your convenience, set the DIP switches (described in Chapter 2) so that the GQ-3500 starts out ready for your usual paper size.
1. If necessary, use SelecType to select the new paper size as described in Chapter 3. If you are not using a standard size, select other from the menu. 2. Push the paper set lever down. 3. Set the manual feed edge tab to the size of paper that you are using. (See Figure 4-2.) Figure 4-2. Manual paper feed guide edge tab 4. Insert a sheet of paper into the manual feed slot. 5. Raise the paper set lever. 6. Print the page. Clearing Paper Jams Clearing paper jams is easy.
Chapter 5 Maintenance and Status Messages The GQ-3500 STATUS indicator messages tell you if some condition exists that may interfere with your printing. You can correct most of these conditions by maintaining your printer as suggested and by following the simple instructions below. Status Messages Status messages are two-digit codes shown on the LED status indicator on the control panel. Some of these messages display in conjunction with indicator lights.

(For more information, see the instructions packaged with the IC card.) - Paper Status Messages All of these messages indicate conditions that are easy to correct. Simply follow the instructions below. JO: paper feed jam When the GQ-3500 has trouble feeding paper from the paper tray, the panel displays this code. To clear this jam, follow these steps: 1.
If there are frequent paper feed jams, clean the cork pads located on the side of the paper tray that fits into the printer. Use a damp cloth to wipe dust and paper fiber off the cork pads. Allow the cork pads to dry before using the tray. (See Figure 5-2.) Figure 5-2. Cleaning paper tray pads J I: paper transport jam When paper jams in the transport section, the panel displays this code. To clear this jam, follow these steps: 1. Open the printer using the latch on the front of the printer.
Figure 5-3. Clearing a paper transport jam - 3. Gently remove the jammed paper. 4. Lower the processing unit back to its original position and press the two comers marked by blue stickers to lock the processing unit in place (avoid pressing directly on the toner cartridge). 5. Close the case and resume printing when the printer has warmed up. A?: paper exit jam When paper jams as it is leaving the printer, the panel displays this code. To clear this jam, follow these steps: 1.
3. Gently remove the jammed paper from the area of the exit rollers. 4. Lower the processing unit back to its original position and press the two comers marked by blue stickers to lock the processing unit in place (avoid pressing directly on the toner cartridge). 5. Close the case. 6. Resume printing when the printer has warmed up.
2. Tap lightly on the comers and edges of the used cartridge. Toner may have gathered along these edges and should be leveled before the cartridge is removed. 3. Press down on the green toner cartridge lock lever and lift up the left side of the toner cartridge, rotating it in the direction of the arrow on the right in Figure 5-4. Remove the cartridge. Figure 5-4. Removing toner cartridge - Take the toner cartridge out of its box. Remove the take-up handle from the top of the cartridge.
Figure 5-5. Installing the toner cartridge 7. Now hold the green toner cartridge lock lever down while you lower the left side of the toner cartridge. Then release the lock lever to lock the cartridge into place. (See Figure 5-6.) Caution Do not press on the top of the toner cartridge because toner may spill into the printer. Instead, press on the edge of the cartridge as shown. If toner does spill into the printer, you must remove it with a small vacuum cleaner. Figure 5-6.
8. Attach the seal take-up lever to the small plastic shaft at the front of the toner cartridge. (See Figure 5-7.) Move the lever back and forth (in the direction of the arrows as shown in Figure 5-7) until it won’t move any farther with moderate pressure. (You will see red markings on the seal when you reach the end of it.> This step peels back the toner seal and releases the toner into the developing unit. Figure 5-7. The take-up lever - 9.
U 1: replace collector unit and lens shield The drum cartridge consists of two separate parts, the collector unit and the drum. The collector unit by itself needs to be replaced about every 10,000 pages. The drum needs to be replaced about every 20,000 pages. Therefore, every other time you replace the collector unit, you also replace the drum. In the latter case, this means you replace the complete drum cartridge.
Figure 5-8. Removing the collector unit 3. Remove a new collector unit from its package and remove the orange plastic holder. 4. Hold the collector unit by its green handles and set it on the drum inside the printer. Pinch the green lock levers open and fit the collector unit down over the drum. 5. Firmly press the blue reset lever located toward the back inside of the printer on the left. (See Figure 5-9.) This lever resets the counter that keeps track of the usage of the drum. Figure 5-9.
6. Now change the lens shield. First, pull the shield out from below the latch on the front of the printer. Next, make sure that both sides of the new lens shield are clean and free of scratches. (Hold onto the green tab so the tab curves down; avoid touching the lens itself.) Slide the end of the lens opposite the green tab into the printer. (See Figure 5-10.) Figure 5-10. Replacing the lens shield 7. Close the printer.
WARNING Opening the printer exposes the fusing unit, which is marked by a CAUTION: HOT SURFACE label. Be careful not to touch the fusing unit. 2. Raise the green handles and lift out the drum cartridge (the collector unit together with the drum). Note If you remove and reinsert the drumcartridge without replacing it with a new one, you must press the reset lever. (See Step 6) 3.
7. Now change the lens shield. First, pull the shield out from below the latch on the front of the printer. Next, make sure that both sides of the new lens shield are clean and free of scratches. (Hold onto the green tab so the tab curves down; avoid touching the lens itself.) Slide the end of the lens opposite the green tab into the printer. (See Figure 5-10 on page 5-13.) 8. Close the printer.
Corrective or Preventive Maintenance Because the GQ-3500’s status messages advise you when to replace supplies and consumable parts, little additional preventive maintenance is required. If the printing quality should decline, however, it may help to clean the transfer charger wire. Do this whenever you replace the drum cartridge, and periodically as required to maintain maximum printing quality. Transfer Charger Wire To clean the transfer charger wire, follow these steps: 1.
Figure 5-12. Cleaning the transfer charger wire Developer roller Transfer 5. Return the cleaning blade to its receptacle. 6. Replace the drum cartridge, then close the case. 7. Test the print quality by turning the printer off, then turning the power on while holding down the ERROR CLEAR button. The status indicator will display seemingly random values as the printer’s memory is checked; when the warm up indication (- - ) appears, release the ERROR CLEAR button. 8.
Chapter 6 Software Control of Printer Features In Chapter 3 you learned how to select many of the GQ-3500’s functions from the control panel. Many more functions are available through the use of software commands. You can send software codes to the printer by writing a program that addresses the printer or by embedding printer comman ds in files printed by your word processing or other application program. This chapter describes how to use the commands that access the printer’s features.
Many of the codes that control the GQ-3500’s features are not letters, numbers, or punctuation. These codes are control codes, which are most easily accessed with BASIC’s CHR$ function. CHR!$ followed by a number sends the ASCII character that number represents. For example, to send the FF (form feed) code, which is ASCII 12, the command is: LPRINT CHR$(12) After the LPRINT command sends the information to the printer, it sends two more codes: a CR (carriage return) and LF (line feed).
Not all fonts are available in both orientations. Be sure that the typeface you want is available in the desired orientation by checking the label on the download font software or IC card. Three of the internal fonts (Courier 10, EDP 13, and Extended Graphics) canbe printed in either orientation. The command to change the orientation is ESC o, followed by a number specifying the desired orientation: 0 for portrait or 1 for landscape.
100 110 120 130 140 150 160 170 180 190 200 210 LPRINT CHR$(27);"y";CHR$(O);CHR$(2); LPRINT "EDP 13 cpi font." LPRINT CHR$(27);"y";CHR$(O);CHR$ (4); LPRINT "Modern PS font" LPRINT CHR$(27);"y";CHR$(O);CHR$(5); FOR X=176 TO 193 LPRINT CHR$(X); NEXT LPRINT LPRINT CHR$(27);"y";CHR$(O);CHR$(O); LPRINT "Courier 10 cpi font" LPRINT CHR$(12); EDP 13 cpi font. &$ern ps font. Courier 10 cpi font.
normal size double-high triple-high/double-wide triple-wide Character Attributes There are other ways to vary the appearance of your printing besides selecting different fonts and sizes. The attributes in this section can be used with any font. Bold type You may want to make some words or headlines stand out by using bold type. This is done with the ESC E command; the ESC F command returns printing to normal.
To print a background pattern, use the ESC - n 1 command (where n is the pattern number you want). The background pattern will print behind each character until you turn it off with ESC - 0 1. The background pattern command differs from the other commands in this section, which affect all characters between the mode on and mode off commands. The background pattern command affects a rectangular area.
Ruled Lines With the GQ-3500, you can easily draw ruled lines, which are very useful in making forms. Although line drawing is a very powerful feature, the command format is rather complex.
. Distance from top edge: 2-l /2” = 750/300” (remainder = 238; quotient = 2) . Direction: horizontal (type 0) . Line thickness: 5/300” (remainder = 5; quotient = 0) . Line len@x 4-l/4” = 1350/300” (remainder = 70; quotient = 5). - The complete command looks like this: LPRINT CHR$(27);"_";CHR$(l);CHR$(l50); CHR$(O);CHR$(238);CHR$(2);CHR$(O); CHR$(5);CHR$(O);CHR$(70);CHR$(5) The following program shows each of the line types and how to vary the line thickness and direction.
Graphics Primitives The GQ-3500 has a set of commands called graphics primitives. These commands allow you to create an image, store it in the printer’s memory, and print it. You can print an image as many times as you like once it has been stored. Creating images The ESC I 1 n command, which invokes the graphics mode, is similar to the other commands with which you are now familiar.
ALLOCATE Reserves the proper amount of printer memory for the image to be stored CIRCLE Draws a circle (or a partial circle, called an arc> LINE Draws a line or a box PAINT Fills an enclosed area with a pattern EXIT Leaves the graphics mode and returns the printer to normal operation. The parameters for these commands are entered as ASCII strings. For example, to send the value 100 to the printer in graphics mode, you use LPRINT “100” instead of LPRINT CHR$(lOO).

Appendix A Command Summary This appendix lists and describes all the commands available on the GQ-3500. The commands are divided into three sections, one for each of the first three operating modes explained in Chapter 2. Page Printer Mode. This section is divided into two parts: the first lists all commands in numerical order and gives the page number where each is fully described. If you know which command you are looking for, consult the numerical list to find the page where it is described.
All three formats are equivalent, and it should be easy to pick the one most suited to your purpose. The simplest type of command consists of a single character to be sent to the printer. For instance, to advance to the next horizontal tab stop the code format is: ASCII code: Decimal: HT 9 Hexadecimal: 09 This code can be sent from a program by sending the code 9 directly. More complex commands consist of two or more character codes.

Appendix E Specifications The first section of this appendix gives the basic specifications of the GQ-3500 printer. The second section tells how to prepare the printer if you have to move it more than a short distance.
Paper and Paper Delivery Paper specifications Types: Plain paper Labels Colored paper Paper with punch holes Overhead projector transparencies Envelopes Weight: - 16 to 24 lbs for automatic feed 16 to 34 lbs for manual feed or automatic feed one sheet at a time Paper size Standard sizes: Horizontal Vertical Type A4 21omm (8.3”) 297mm (11.7”) A5 148mm (5.8”) 210mm (8.3”) 257mm (10.2”) 182mm (7.2”) B5 11” Letter 8.5” 14” 8.5” WFJ Half Letter 5.5” 8.
MPBF (mean prints between failures) 18,000 sheets (1,500 per month x 12 months) MTBF (mean time between faihrres) 3,fNIO hours Durability 5 years or 180,CUO sheets (3,000 per month x 60 months) Electrical Voltage 120V AC Consumption Less than 600 W during continuous printing Insulation resistance 10 Mohms between AC power line and chassis Dielectric strength Can withstand 1.25 kV for 1 minute between primary and frame ground or 1.
Environment Temperature Operation: 50” F to 90” F (10’ C to 32” C) Storage: -20” F to 109” F (-29” C to 43” C) Humidity Operation: 20% to 80% Storage: 10% to 90% Transportation There are several precautions you should take when packing the printer for transportation. You should try to pack it as closely as possible to the way it was packed when you first received it. The following points are especially important: Remove the drum cartridge from the printer and put it in its original packing materials.
Appendix F Parallel Interface The GQ-3500 is equipped with a Centronics compatible parallel interface, described in this appendix. You may purchase an optional serial interface from your dealer. Installation and operating instructions for your serial interface come packaged with the interface card and are not included here. In most cases, the parallel interface will work without any changes. However, you can change several options on the interface.
Table F-1. DIP Switch 4 Switch Function ON 4-1 ACKNLG delay OFF See Table F-2 4-2 4-3 Printer select ON OFF 4-4 Data length 8 bits 7 bits I Explanation Sets the delay period from the ACKNLG to the BUSY signals. When this switch is ON, the printer cannot be deactivated by software codes. For most uses and commercial software programs you should leave this switch ON. When this switch is ON the printer accepts all 8 data bits. When this switch is OFF the eighth data bit is ignored. Table F-2.
The first jumper, labeled AUTO on the left and PS3 on the right, controls the AUTO FEED function. The AUTO FEED signal on pin 14 is ignored unless this jumper is in the AUTO position. The second and third jumpers change the state of two of the signals on the interface. The STROBE (STB) and BUSY signals can be changed from + to -by changing the corresponding jumper. Pin Assignments Table F-3 shows connector pin assignments and describes the respective interface signals. Table F-3.

Continued Signal Pin Return Pin Signal Dlrectlon 2 3 4 5 6 7 20 21 22 23 24 25 26 27 DATA1 DATA2 DATA3 DATA4 DATA5 DATA6 DATA7 DATA8 IN IN IN IN IN IN IN IN a 9 Deecrlptlon DATA1 to DATA8 carry the parallel interface data. These signals use positive logic (HIGH = 1, LOW = 0), and the levels of these signals must be kept constant for 0.5 microsecond before and after the active edge of the STROBE signal.
Table F-3. Continued Signal Pin Return Pin Signal Direction 11 29 BUSY OUT This signal indicates whether or not the printer is ready to receive the next character. Data input is normally possible when this signal is LOW. However, the phase of this signal can be changed so that a LOW level indicates that the printer is busy by moving the third jumper under Ji from + to -BUSY. 12 30 PE OUT This signal, which is normally LOW, goes HIGH when the printer runs out of paper.
Table F-3. Continued Direction Signal Pin Return Pin Signal 18 - NC Unused. 19-30 - GND Signal ground level for twisted pair return. 31 16 lNlT IN Description Dropping this signal to LOW resets the printer to the power-on state. Any data that has been received bythe printer but not printed is lost. This signal is normally HIGH; it must go LOW for at least 50 microseconds in order to reset the printer.
Table F-3. Continued 1 Signal Pin Return Pin Slgnal Direction 36 - m IN Deecrlptlon if this signal is HIGH when the printer is turned on, and DIP switch 4-3 is OFF, then the device control codes DC1 and DC3 are effective. Otherwise DC1 and DC3 are ignored. This signal is ignored in the Line Printer mode; i.e., DC1 and DC3 are ignored. Notes: The column headed “Direction” refers to the direction of the signal as viewed from the printer.
GQ-3500 Options The GQ-3500 printer is designed to accept a variety of options. The GQ-3500 accommodates an optional serial interface board, which is available from your Epson dealer. In addition, the two IC (Integrated Circuit) slots in the top cover allow the use of IC cards that can add fonts or identity modes to the operation of the printer. For example, the #5400 Font Card makes available 8 additional fonts.
