2 Preventive Maintenance
Preventive Maintenance 2 This chapter identifies scheduled maintenance actions and provides illustrated procedures for cleaning the 3600 printer. Preventive Maintenance Actions and Intervals Preventive maintenance consists primarily of scheduled cleanings, but also occassional performance checks and, possibly, adjustments based on those checks.
00 Printer Maintenance Manual Inspecting the Printer You should routinely inspect the printer and the rest of the data collection system. Your inspection needs to address the following and similar concerns: • Make sure the printer is properly grounded. • Make sure the printer’s AC power source is within tolerance. • Make sure the printer is clean. • Make sure the printer is away from liquids. • Inspect the work environment for cleanliness and arrangement.
Preventive Maintenance 2 Removing the Media Cover Most of the cleaning procedures require that you remove the media cover. To remove the media cover 1. Place your fingers in the space at the lower center edge of the media cover and pull the bottom of the cover away from the base of the printer. 2. Grasp the front of the media cover and lift the front of the cover upward.
3600 Printer Maintenance Manual Cleaning the Printhead Since the printhead must maintain close contact with the media to provide good print quality, cleaning media debris from the printhead is very important. Clean the printhead after every roll (or 6,000 inches) of media or whenever necessary. CAUTION Caution Do not use sharp objects such as knives or screwdrivers to scrape the printhead clean. Cleaning with sharp objects will damage the printhead.
Preventive Maintenance 2 3. Remove the media from the paper path and the ribbon (if installed) from the TTR supply and takeup hubs. 4. Use a cotton swab moistened with alcohol to remove any dirt, adhesive, or debris from the print surface on the bottom of the printhead. Po we r Ale rt Em pty /P au se Fe ed /P au se Inte rme c 36 00 Thermal printhead 3600M.012 5. Wait 5 to 10 seconds for the print surface to dry. Reload the media (and ribbon if used). 6.
3600 Printer Maintenance Manual Cleaning the Rollers and Tear Bar Cleaning the platen roller and the tear bar preserves print quality by ensuring close contact between the media and the printhead.

4 Troubleshooting
Troubleshooting 4 This chapter provides you with information that will help you determine why a printer may not be working and how to get it working again. About Troubleshooting and Repair Use the information in this chapter to identify the cause of a failing printer. It is assumed that a printer is not working and that the troubleshooting actions referenced in the user’s manual were not used, failed to clear the problem, or pointed to a printer malfunction.
3600 Printer Maintenance Manual Troubleshooting Checklist If the host receives an error message or a functional problem with the printer is encountered, the user’s manual starts with the following: 4-4 • Check whether the printer sends an error code to the host in response to a command. • If an error code is sent, find it in the “Error Codes” table in this chapter. Try the solution given for the respective error code to attempt to correct the problem.
Troubleshooting 4 Error Handling This section describes how the 3600 printer handles certain error conditions it may encounter in printer or programming commands. Error codes sent to the host, the problem the code is reporting, and the usual solution are listed in a table at the end of this section. Syntax Errors The 3600 printer responds to syntax errors in the messages it receives from the host by attempting to execute the commands. It does not ignore a command with a syntax error.
3600 Printer Maintenance Manual Invalid Numeric Character Errors If non-numeric characters are included within a numeric data string in a command, the printer disregards them and continues to process the rest of the valid numeric characters. However, if a non-numeric character begins the numeric data string, the printer uses a default value for the affected command.
Troubleshooting 4 Printer Errors Error Code Problem Solution 00 No error. 01 Invalid bar code check character. Verify the bar code check character modifier used in the bar code program command. 02 Invalid number of bar code characters (Code UPC/EAN). Verify the number of bar code characters used in the bar code program command. 04 Bar code check character within numeric field marks. Check the bar code program command for accuracy.
3600 Printer Maintenance Manual Printer Errors (continued) Error Code Problem Solution 32 Non-immediate command or data received after buffer full. Allow the printer to empty the buffer contents before sending commands or data. 33 Invalid field delimiters. Check for all pairs of field delimiters, and make sure both are numeric or both are alphanumeric. 34 Invalid escape command. Correct the escape command syntax. 35 Invalid data shift command. Correct the shift command syntax.
Troubleshooting 4 Printer Operation Problems If a printer is not operating correctly, try locating the problem and implementing the solution from the following table: Symptom Possible Causes Solution No power or loss of power. AC power cable is damaged or disconnected. Make sure the power cable is plugged into both the printer and an outlet or power strip. Replace the cable if it is damaged. Printer circuit breaker tripped. Turn the printer off and then back on again (determine why it tripped).
3600 Printer Maintenance Manual Print Quality Problems If labels are not printing properly, try locating the problem and implementing the solution in the following table: Symptom Possible Causes Solution Blotches on labels. Dirty printhead. Clean the printhead. Dirty media path or rollers. Clean the media path. Poor quality label or ribbon stock. Use only Intermec label and ribbon stock to ensure superior print quality and product performance. Darkness adjust control is set incorrectly.
Troubleshooting 4 Symptom Possible Causes Solution Print quality is poor. Incorrect media sensitivity. Change sensitivity setting to match the type of media you are using. If sensitivity is set correctly, try changing the dark adjust. The darkness of label print is too light or too dark. Properly set the darkness adjust control. Printhead, platen roller, or label path are dirty. Clean printhead, platen roller, and label path. Uneven print contrast (density). Adjust the bias adjust screw.
3600 Printer Maintenance Manual Communications Problems If a printer is not receiving downloaded data, consider the causes and solutions in this section. Symptom Possible Causes Solution Printer does not communicate with the host. Serial port is incorrectly configured. Make sure the printer’s serial port settings match those of the host. Print a software test configuration label to check the serial port settings. Disconnected, damaged, or incorrect I/O cable. Check the connections at both ends.
Troubleshooting 4 To check for communications problems 1. Check the cabling from the printer to the host system. 2. Check the interfacing of the devices that are communicating with the printer. 3. Check the printer for proper electrical operation of the serial communications port. 4. Test to see that the host system is not overrunning the printer’s input buffers. 5. Check to see that the data string being sent to the printer contains the correct information.
3600 Printer Maintenance Manual Electromagnetic and Radio Frequency Interference Noise induced in interface cables can result in the printer receiving false data. This condition may cause the printer to skip printing a label or lockup. Sources of electromagnetic interference (EMI) and radio frequency interference (RFI) are radio transmitters, ignition systems, and relays. To eliminate the effects of EMI and RFI, use low capacitance, twisted pair, shielded cables.
Troubleshooting 4 AC Power Problems (Surges, Sags, Spikes, Noise, and Outages) Most environmental problems involve the AC power line. In the 3600 printer, 115V supply voltages can range from 90 to 132 VAC. Outside the U.S., 230V supply voltages can range from 180 to 264 VAC. Voltage overages or underages can result from poor utility regulation to in-plant loading of the power service. Use a power line monitor, such as the BMI 4800, to look for power service problems.
3600 Printer Maintenance Manual Miscellaneous Problems The following information identifies some possible printer problems and what might be their cause. 4-16 • Problems with printer-to-computer communications, motor control, or media advance may be caused by a faulty main PCB assembly.

A Appendix
Appendix A This appendix describes the theory of operation for the 3600 printer. Functional Description of the 3600 Mechanics This section describes the basic mechanical functionality of the 3600 printer. The 3600 printer has a sheet metal frame (base plate and main deck plate) to which mechanical and electrical components are attached. The printer holds, moves, routes for contact by the printhead, and stores label stock and ribbon by electronically controlled mechanical means.
3600 Printer Maintenance Manual A media supply assist roller and brake assembly are part of the media supply post function. The free spinning roller reduces the drag of the media core over the stationary supply post, allowing the media to turn smoothly during printing. When printing stops, the media slackens under the upper media guide, causing the media brake pedal and brake arm to lower onto the rubber contact strip on the brake drum, which inhibits media roll momentum by stopping the assist roller.
Appendix A Power Fail Detection The power fail detection circuitry consists of IC U31, diodes D7, D8, D9, and D11 and various resistors and capacitors. Diodes D7 and D8 rectify the incoming 12 VAC, and R101 and R107 act as a divider. D9 is a zener diode used to prevent the input on U31 from exceeding +5V. D11 is a 1.235V reference. When the voltage at pin 3 of U31 exceeds 1.235V, the output is pulled up by a 10K resistor, R183. R104 adds some hysterisis to help filter out noise or brownouts.
3600 Printer Maintenance Manual Motor Driver The motor driver circuit of the 3600 consists of ICs U2, U21, U17, and U19; discreet parts Q16, Q1, Q3, Q4, Q6, Q11, Q12, Q13, Q14; and associated diodes, resistors, and capacitors. The eight D-MOS FETs make up a dual full-bridge motor driver. There are four FETs to drive each motor phase. There are two FETs at each end of each motor phase. When a phase is driven or turned on, one FET on each end of a phase is turned on.
Appendix A Processor The processor used in the 3600 is a MMC68332 32-bit integrated microcontroller. Based on the MC68020, the MC68332 contains four peripheral modules: CPU32, a 32-bit central processing unit; TPU, a complex, programmable time processor unit; QSM, a queued serial module; and SIM, a system integration module. The MC68332 was chosen for its 32-bit processing power along with its high level of integration.
3600 Printer Maintenance Manual Channels 7 and 8 These outputs control the front panel LEDs. They can be set to high, low, or square wave outputs. The square wave output frequency is programmable. Channel 9 This output is reserved. It has RXD as an input for autodetection of the serial communications parameters. Channel 10 This is an input for the ribbon sensor. The channel detects transitions on the input.
Appendix A Memory The MC68332 has separate address busses and data busses. All I/O is memory mapped and the SIM chip selects are used to select program space, data space, and I/O. Static RAM The 3600 comes with 128K of battery backed static RAM. The RAM is configured as 128Kx8. The chip select for accessing SRAM should be configured to at least one wait state. The RAM can also be upgraded to 512K x 8 by swapping the component at location U6.
3600 Printer Maintenance Manual Communications Interface The communications interface for the 3600 follows the Intermec Standard Data Connector standard. J1 is a 25 pin D-sub connector that supports both RS-232 and RS-485 interfaces. U1 is the RS-485 driver/receiver and U22 and U4 are the RS-232 driver and receivers. To further enhance the interface to support DTR/RTS flow control, the DTR pin is driven with the PIN 14 signal.
Appendix A Chip Select Generation GALs U23 and U25 are designed to take the MC68332 bus control signals and convert them into ASIC and I/O option control signals. A state machine governs the timing of the signals and also dictates that the /OPTION_ASICCS from the processor be programmed for two wait states. I/O Option Connector The I/O option connector J8 is a 40-position pin field. Two chip selects, /OPTION∗ and /BOKI/O∗, are used to select either the board identification number or the data port.

3600 Printer Maintenance Manual Functional Description of the 3600 Software This section describes the basic software functionality of the 3600 printer. Band Buffering and Font Caching Image band buffering and font caching allow Intermec printers to image and print labels at the same time. Virtually any label length can be accommodated due to the circular system of using image memory.
Appendix A The ideal setting keeps imaging just ahead of printing. This ideal setting can be found by the proper selection of image bands and print speed for the label format being printed. Image Band Example The following example shows a format print using image bands. The label is 5 inches long and is divided into five image bands. The printer is configured for three image bands, which means that three bands will be imaged before printing begins.
3600 Printer Maintenance Manual The third 1 inch of the label is imaged into the third image band. Printing begins from the first image band, as indicated by the arrow. At this point, all three available image bands have been filled. The first band will be reused after it has been completely printed. When the first image band is emptied (printed), the fourth band is imaged into it. Printing continues from the second image band.
Appendix A The final 1 inch of the label is imaged into the second image band. Printing continues from the third band. At this point, the label has been completely imaged but printing has not finished. After the third image band is emptied, printing continues from the first image band. Imaging of a second label could begin in the third image band while the first label is still printing.
3600 Printer Maintenance Manual Font Caching Most of the imaging time during text creation is spent converting character description data into character images. The remainder of the time is used to copy the character images into image RAM. Font caching helps to eliminate the reimaging of characters that have already been used. With font caching, a character is imaged into the cache the first time it is requested. It is then copied from the cache into the appropriate area of image RAM.
