Chapter 2 Testing and Connecting Your Printer The Control Panel ................................................................... Display ................................................................................. Indicator lights .................................................................... Buttons ................................................................................. 2-2 2-2 2-3 2-4 Testing the Printer.. ................................................................
The Control Panel The printer control panel is made up of three elements: buttons, indicator lights, and a liquid crystal display. You use the buttons to select printer settings and functions, and the indicator lights and display let you monitor the current status of the printer. Display The display shows the printer’s status and available options. The types of information displayed and an example of each are given below. Status messages, such as WARMING UP, indicate the printer’s current status.
The Control Panel Indicator lights LEVEL 1, LEVEL 2 One of these lights is on when the printer is in the SelecType mode, depending on which level you enter. These lights are off if the printer is not in SelecType mode. ON LINE The light is on when the printer is on line, indicating that the printer can receive and print data. When the printer is off line, this light is off. CONTINUE This light is on when the printer is in HP emulation mode and there is information on the page.
The Control Panel Buttons You use these four arrows to select and set printer options in SelecType mode. Their functions are described in detail in Chapter 3. FEED In HP emulation mode, this button is used like the form feed key on an HP LaserJet. If there is anything on the current page, pressing this button causes the printer to print the page. If there is nothing on the current page, this button is ignored. This button operates only if the ON LINE light is on and WAITING appears on the display.
The Control Panel RESET-If you press this button while QUIT CONTINUE COPY END/RESET THE JOB is on the display, the display changes to QUITTING THE JOB and the job is flushed from the printer’s memory. If you press any other buttons, the printer returns to its previous status without printing data. Select Type Enters or exits SelecType mode. Press once to enter Level 1; press twice to enter Level 2. For a complete description of the two SelecType levels and their functions, see Chapter 3.
Testing the Printer When you turn on the printer, it automatically prints a start page, containing simple text and graphics. Normally, processing of the start page begins about 70 seconds after you turn the printer on. The start page does not print if the STARTPAGE option in SelecType Level 2 is set to OFF or if the printer takes more than three minutes to warm up. Note: In most cases, leave the STARTPAGE option set to on.
Testing the Printer 1. Push the paper set lever forward to the manual position. 2. Slide the paper guides all the way open, as shown below.
Testing the Printer 3. Take a stack of A4 or letter-size paper (high-quality copier paper is recommended) and tap the edges of the paper on a flat surface to even up the stack. 4. 2-8 Insert the stack of paper into the paper cassette, making sure that the top of the stack does not exceed the maximum height mark inside the cassette, as shown below. Gently push the paper in as far as it will go.
Testing the Printer 5. Slide the paper guides together until they both rest lightly against the paper. 6. Pull the paper set lever back to the automatic position.
Testing the Printer Note: The paper set lever must be in the automatic position before paper can be fed automatically from the paper cassette. If you set the lever to the manual position when the printer is on, automatic paper feeding is disabled and the OUT OF PAPER message appears on the display, even if there is paper in the paper cassette. Now you’re ready to turn on the printer and print a start page.
Testing the Printer CAUTIONS: Do not open the printer cover while the printer is warming up or printing. After you turn off the printer, always wait at least five seconds before turning it back on. It takes approximately 70 seconds for the printer to complete its power-on routine. Then the printer automatically prints the start page. After the page has printed, the printer is on line and the display shows READY. If the display remains blank, see Chapter 7 for troubleshooting information.
Testing the Printer 2-12 Testing and Connecting Your Printer
Testing the Printer If the start page prints correctly, you can skip to the section on connecting the printer to your computer later in this chapter. If the start page does not operate properly, see Chapter 7 for troubleshooting information. Adjusting print density You can control the overall density of the printed image with the print density control knob. If your test print is too light or too dark, adjust the print density as follows: 1. Lift the latch to open the printer cover to the lower position.
Testing the Printer 3. For darker print, turn the knob clockwise as shown. Note: Increasing the print density increases toner consumption. If you select darker print, you may need to replace the imaging cartridge more often. 4. For lighter print, turn the knob counterclockwise as shown. Note: If you want to return the print density setting to the factory setting (center position), align the vertical line on the knob with the dot on the scale.
Testing the Printer 5. Close the printer cover. 6. Print a start page again to check the new print density setting. To do this, turn the printer off, wait five seconds, and turn it on again.

Paper delivery method ....................................................... Paper feed method.. .
Choosing Paper With this printer you can print on many sizes and types of paper. You can also use other types of media, such as envelopes, labels, and overhead projector transparencies. The printer feeds most types of media automatically from the paper cassette, while some media require hand-feeding for greater control. This chapter describes the paper delivery choices and how to select and load paper. The type of paper you use in your printer directly affects the quality of your printed output.
Choosing Paper Standard office paper -- You can use the printer’s paper cassette to automatically feed most types of 16 to 24 lb. (60 g/m2 to 90 g/m2) paper. This typically includes such paper as copier paper, memo sheets, cotton bond, and letterhead. If you feed paper manually or load it one sheet at a time through the paper cassette, you can use 16 to 42 lb. (60 g/m 2 to 157 g/m 2) paper. For best results, use paper made especially for laser printers.
Choosing Paper Envelopes-You can load envelopes as shown below. Load envelopes along the length of an envelope. The printing quality on envelopes may be irregular because different parts of an envelope have different thicknesses. If the printing is too light, turn the print density knob counterclockwise. Always return the print density knob to the center position when you go back to printing on ordinary paper. Also, for better printing of envelopes, use the optional face-up output tray.
Choosing a Paper Size The printer can feed several sizes of paper automatically. To select a paper size, simply change the paper size setting with SelecType. You may also need to adjust the paper guides on the paper cassette to match the size of the paper you want to use. Note: If you are using the optional lower paper cassette, see Appendix A for instructions on selecting a paper size. The table below lists all of the paper sizes on the SelecType menu.
Choosing Printing Methods The EPL-7500 offers you several printing methods. Your choices depend mainly on the type of paper or other print media you want to use. l l Paper delivery method -- Choose face-down output or face-up output (with the optional face-up tray). Paper feed method -- Select either automatic or manual paper feed. Paper delivery method The printer can deliver paper face-down on top of the printer or face-up into the optional face-up tray.
Choosing Printing Methods Then set the OUTPUT option in SelecType Level 1 to face-up delivery. See Chapter 3 for SelecType instructions. Even with the optional face-up tray installed, you can still choose either face-up or face-down delivery. To choose face-down delivery when the face-up output tray is installed, move the paper path lever to FACE DOWN, and set the OUTPUT option to facedown.
Choosing Printing Methods Feed Delivery Auto or manual Face-up or face-down Manual or auto Face-up Manual or auto Face-up or face-down Transparencies Manual Face-up or face-down Labels Manual Face-up Material Regular Paper (60 - 90 g/m ) 2 (16-24 lb.) Heavy Paper (90 - 157 g/mZ) (24 - 42 lb.) Envelopes Note: To print on letterhead paper, load the paper face-up with the top of the paper entering the printer first.
Loading Paper in the Cassette The standard paper cassette holds up to 250 sheets of paper. To load paper in the cassette, follow these steps: 1. Push the paper set lever forward to the manual position, as shown below. 2. Slide the paper guides all the way apart, as shown below.
Loading Paper in the Cassette 3. Take a stack of paper and tap the edges of the paper on a flat surface to even up the stack as shown. 4. Insert the stack of paper into the paper cassette, making sure that the top of the stack is below the maximum height mark inside the paper cassette. Push the paper in gently as far as it will go.
Loading Paper in the Cassette Note: To print on long paper such as legal-size paper (8 l/2 X 14 inches), open the paper support as shown below. 5. Slide the paper guides together until they both rest lightly against the stack of paper.
Loading Paper in the Cassette Pull the paper set lever to the automatic position until it clicks into place. 6. Note: The paper set lever must be set back to the automatic position before paper can be fed automatically from the paper cassette. If the paper set lever is forward while the printer is on, the control panel displays the OUT OF PAPER message, even if there is paper in the cassette. 7. If you have changed the paper size, use SelecType to choose the new paper size, as described in Chapter 3. 8.
Loading Paper Manually If you want to print labels, envelopes, transparencies, heavy paper (over 24 lb. or 90 g/m2), or other special papers, you can load the paper one sheet at a time in the paper cassette or you can handfeed it. Hand-feeding is more convenient, especially when you want to print a small job on a different type of paper than is already loaded in the cassette. You can hand-feed paper ranging in size from 92 X 160 mm (3.62 X 6.3 inches) to 216 X 356 mm (8.5 X 14 inches).
Loading Paper Manually 5 Adjust the manual feed paper guides to match the size of paper you are using, as shown below. 6. Insert a sheet of paper into the manual feed slot as far as it will go. (The control panel displays the READY message when you insert the paper correctly.
Loading paper Manually Note: Insert the paper with the side you want to print on face-up. For example, to print on the back of a printed page, load the paper with the blank side face-up. 7. For labels, envelopes, transparencies, and heavy paper, installing the optional face-up output tray is recommended. Set the paper path selector on the output tray for face-up delivery. 8. Press ON LINE to set the printer on line; then print the page.

Controlling the Printer ........................................................... Graphics programs .............................................................. Desktop publishing programs ............................................
Using Your Printer with Application Software Once you’ve set up the printer you can start using it with your application programs. Most application programs ask you to specify the type of printer you are using so that the program can take full advantage of the printer’s features. Many programs have an installation or setup menu that presents a list of printers to choose from. If your program has a printer selection menu, follow the instructions below to get the best performance from your printer.
HP emulation mode If your application program doesn’t support the PostScript language, or if you are using a program written specifically for the HP LaserJet, use the SelecType Level 1 SOFTWARE option to set your printer to HP emulation mode. Then choose the first printer available from the list below from your application program’s printer selection menu.
Controlling the Printer Most application programs contain a number of built-in functions that you can use to control the printer. When you use these features, special codes are inserted into your document by the program. When you print a document, these special codes are converted by the application program into commands understood by the printer. Application program set the page orientation, margin widths, the number of text lines-per-inch, the number of copies, and other printer features.
Controlling the Printer Desktop publishing programs Whether you’re a serious desktop publisher or just starting out, you’ll get professional results from your EPL-7500 if you choose a desktop publishing application program written specifically for PostScript printers. When you set up a desktop publishing application program, select either the EPL-7500, PostScript printer, or LaserWriter from the program’s printer selection menu. Nearly all desktop publishing programs support the PostScript language.
Controlling the Printer Word processors Word processors usually let you use a fixed set of printer features by tagging the text to be altered. When the document is printed, the tags are recognized and translated into suitable commands for your printer. Some programs display these tags on screen; others display the text exactly as it will appear when printed, for example, in bold or italics.
Using PostScript Fonts Professional-looking desktop publishing is easy with the EPL-7500. Your printer has 35 built-in fonts in 11 font families to help you create exciting documents. The PostScript resident fonts listed below can be combined to create newsletters, brochures, presentations - whatever your special needs are. Once you choose a PostScript driver for your printer, you should be able to use any of the fonts resident in your printer to design your documents.
Using PostScript Fonts EPL-7500 resident fonts All of the fonts listed below are resident in your printer in PostScript mode. See Appendix B for more information on PostScript fonts and for information on the fonts available in HP emulation mode.

Using PostScript Fonts ITC Avant Garde Book ITC Avant Garde Book Oblique ITC Avant Garde Demi ITC Avant Garde Demi Oblique ITC Zapf Chancery Medium Italic* l *This font comes only in the calligraphic italic style shown above.
Using PostScript Fonts Working with fonts Understanding the terms associated with printing will help you design better documents. This section explains some basic terms about printing with fonts. Serif and San Serif Styles Most font styles can be described as either serif or sans serif. Both of these terms originated with typesetting, and they refer to the appearance of the characters.
Using PostScript Fonts Point size Point size describes the vertical height of a font. This unit of measure originated with typesetting, and is a useful term to describe type size. A point is 1/72 of an inch. The figure below shows several point sizes of the same font: 8, 10, 14, 18, 24, and 36-point Times Roman. The resident fonts provided with your printer can be scaled to almost any point size, depending on your software.
Using PostScript Fonts You can also use PostScript to arrange your text along any path-a curve, a circle, or almost any shape. The example below shows text arranged along a freeform curve. Check your application program documentation for detailed instructions on creating these effects. Orientation Orientation refers to the direction of print on the page. You can print across the narrow dimension of the page (in portrait orientation) or the across the wide dimension of the page (in landscape orientation).

PostScript Mode This section describes the resident fonts available in PostScript mode. To select a resident font, you can use your application programs or printer commands. Your printer has two kinds of resident fonts: bitmap and outline. Bitmap fonts are ready to print with predefined attributes, such as point size and weight. Outline fonts are defined by mathematical equations that give you a range of possibilities not available with bitmap fonts.
PostScript Mode Resident outline fonts The following is a list of the 35 outline fonts available in PostScript mode. The font names and font numbers used by PostScript language operators are in the specifications in Chapter 8.
PostScript Mode Palatino Roman Palatino Bold Palatino Italic Palatino Bold Italic ITC Zapf Chancery Medium Italic ITC Zapf Dingbats B-4 Appendix B
HP Emulation Mode The resident bitmap fonts listed on page B-2 are also available in HP emulation mode. See page B-2 for print samples. To select a font, you can use your application program or printer commands.
Glossary application program Any software program designed to carry out a particular task. For example, word processing or graphics packages are application programs. ASCII American Standard Code for Information Interchange. A standardized way of assigning numerical codes to characters and control codes. The system is widely used by manufacturers of computers, printers, and software. baud rate A measure of the speed of data transmission. It is used when setting a serial interface on a computer and printer.
byte A unit of information consisting of eight bits. A byte usually corresponds to one character or code. cache The area of memory that stores internally generated fonts character set A collection of letters, numbers, and symbols. control codes Special codes used to control printer functions such as sounding the beeper and performing a carriage return or line feed. decimal See number systems default A value or setting that takes effect when the equipment is turned on, reset, or initialized.
drum The part of the printer mechanism where the image is formed and transferred to the paper. EEPROM Electrically Erasable Programmable Read Only Memory. The portion of the printer’s memory holding SelecType’s default settings. It may be erased and reprogrammed, enabling you to change the default settings, but it also saves settings even when the printer is turned off. electrophotographic process The printing method used by the EPL printer.
imaging cartridge The imaging cartridge contains a photosensitive print drum and a supply of toner. initialization Returns the printer to its defaults (fixed set of conditions). interface The connection between the printer and the computer. A parallel interface transmits data one character or code at a time, and a serial interface transmits data one bit at a time. AppleTalk communicates between the printer and Macintosh computers. landscape Printing that is oriented sideways on the page.
number systems Three number systems are commonly used with printers: decimal is base 10 and uses the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. This is the most familiar system. hexadecimal (hex) is base 16 and uses the characters 0-9 and A-F. This is frequently used by programmers. Any decimal number between 0 and 255 can be expressed by a two-digit hexadecimal number. binary is base 2 and uses only the digits 0 and 1. All information in computer systems is handled in binary form.
parity A method of checking the reliability of data transmission between the computer and printer. point size The height of a particular typeface as measured from the top of the tallest character to the bottom of the lowest. A point is a typographic unit of measure equivalent to l/72 of an inch. portrait Printing that is oriented upright on the page (as opposed to landscape, in which printing is oriented sideways on the page). This is the standard orientation for printing letters or documents.
SelecType A feature of the printer that allows you to make centain printer settings from the front panel. serial interface See interface. start page See test print. symbol set A collection of symbols (letters, numbers, and special characters) used by a font. Symbols are assigned to specific codes in a character table. test print Also called start page. A method of checking the operation of the printer.
