o INTRODUCTION
Before Read the section titled "Preliminary Checks" before
You Start you begin troubleshooting. Items listed here do not require any disassembly, tools, or special setups and can save you time and your customer money when troubleshooting the ImageWriter LQ.
If the suggestions in "Preliminary Checks" do not correct the problem, proceed to the appropriate symptom/cure chart.
How to Use First locate the symptom that comes closest to
the Symptom/ describing the problem; then perform the first
Cure Chart corrective action on the solution list. If that corrective
action does not fix the problem, proceed to the next action. If you replace a module and find that the problem remains, reinstall the original module before proceeding.
If a step asks you to test something, the procedure can be located elsewhere in this section.
If a tested component is defective, replace it. If it is not defective, proceed to the next action listed.

• Uneven print pattern – The printer is sensing a color ribbon carriage.
on self-test (four Make sure the black ribbon carriage is pressed
lines light–three down completely on the left side to activate the
lines dark) ribbon microswitch.
• Printing less – To get the best quality output when printing from a
then best quality Macintosh, the system file must have the correct fonts. Be sure the system has fonts in the same size as the desired output ("1X" font) as well as its 3–times equivalent ("3X" font). For example, if your document is in Times 12 point, you must have both Times 12 and Times 36 installed in your system file for highest quality output. If the 3X font is absent, the output will be scaled from an available font, and there will be some loss in print quality.
• Printing has 1. For the best print quality, instruct the customer to squashed lines; use the pull tractor and the bottom feed slot. The misregistration paper should be stacked at least 12 inches below problems when the printer. The straightness of this paper path using pin feed paper combined with the pull tractor helps to keep the paper securely around the platen. This paper path is strongly recommended for printing labels or multipart forms.
2. If the unit does not have a slotted table, instruct the user to be sure that the power cord or printer cable does not obstruct the paper path, and to avoid printing in the top and bottom one inch of the paper (the areas where the squashed line and misregistration problems will be the most apparent).
• Problems using – Instruct the customer to use the bottom feed slot, labels or multipart and the pull tractor for the highest quality output, forms and to avoid backing out paper, especially labels and forms. (Backing out labels onto the push tractor may cause labels to peel off onto the platen or may dislodge a mylar guide inside the printer.) Cut the paper at a perforation, and advance the paper forward to remove pinfeed paper from the printer.
• Printing on the – When printing from a Macintosh and using the platen or over a push tractor, set dip switch 2-8 ON to load paper
perforation when beneath the bail (about 1 inch beyond the print using the push line). This eliminates the possibility of printing on
tractor the platen or over a perforation when the printer
driver executes its reverse linefeeds at the
start of a print job.
DIP switch 2-8 controls how far the paper is loaded into the printer. The default setting brings the paper up to the first printable line when you do an automatic paper feed with paper loaded on the push tractor.
• Words touching or – If the printer is being used with a Macintosh,
slightly overlapping update to version 2.0 or greater of the LQ driver.
• Page setup – If the customer notices a format difference in the problems between document when printing from an ImageWriter LQ, different printers and then from a LaserWriter, inform the customer that he must use Page Setup from the File menu each time a different kind of printer is used. Since the ImageWriter LQ and LaserWriter have different imageable areas (the ImageWriter page size is slightly larger than that on the LaserWriter), Page Setup is necessary to reformat the document for ImageWriter LQ printing.
Cut Sheet Feeder
• No access to second – Make sure to set your dip switches (2-5 and 2-6) or third bin for the number of bins you have installed (see Table 10 in the Basics section). If these switches aren't set properly, the printer will not be able to access the second or third bin. The switches have to be set only once; if the Cut Sheet Feeder is removed to use pinfeed paper, you do not have to reset the switches.
• Printer does not – The ImageWriter LQ expansion bin can either be recognize bin 3 the second or third bin of the Cut Sheet Feeder. If the gear configuration plug is left in, the bin will function as bin 2; if the gear configuration is removed, the bin becomes bin 3.
• Paper skewed (bent) – Add 3.1 mm rubber bumpers to the bottoms of from expansion bin 3 expansion bins 2 and 3. See Additional Procedures for correct placement.
• Documents going into – Bins are selected through the Options button wrong bins on the Print dialog box of the software being used. You can select up to two bins per job, but your application must spool the whole document as a job. Currently some applications treat each page of a file as a separate job, and all pages will come out of the bin selected under "First Sheet From." Other applications will allow you to print one job from two different paper bins. Have the customer check whether the application used supports multiple–bin feeding.
• Envelope feeding – Since envelopes generally are thicker than cut problems sheets, the customer must be aware of the following
• Make sure to adjust the paper thickness lever when printing envelopes.
• Reset the paper thickness lever back to
position 1 when you resume printing on cut sheets.
• Because of the difference in paper thickness between cut sheet and envelopes, do not run cut sheets and envelopes in the same print job.

o TESTING THE PRIMARY AND SECONDARY FUSES
Materials Required Digital multimeter
Procedure 1. Turn off the printer and remove the main cover.
2. Remove the fuse to be tested and place a probe at each end of the fuse.

Materials Required Digital multimeter
Needlenose pliers
Procedure 1. Turn off the printer and remove the main cover.
2. Remove the power switch from the case by pressing, with the needlenose pliers, the two plastic tabs at the sides of the switch and, at the same time, pushing the switch out of the case.
3. Connect the multimeter between the two white
wires of the power switch and toggle the switch on and off.
When you turn the power switch on (1), the resistance should be 0 ohms. When you turn the switch off (0), the resistance should be infinite.
If the resistances are not as indicated, replace the power switch.
4. Repeat step 3 for the black wires.

main board connector CN10 (Figure 1, #1).
FIGURE 2
3. Connect the multimeter between pins 1 and 2 of the
removed connector and toggle the home position
switch (Figure 2, #1) with your finger.
When you depress (close) the home position switch, the resistance should be 0 ohms. When you release (open) the switch, the resistance should be infinite.
If the resistances are not as indicated, replace the home position switch.

2. Disconnect the paper-handling change switch cable from main board connector CN18 (Figure 4, #1).
(Graphic not available)
FIGURE 5
3. Connect the multimeter between pins 1 and 2 of the removed connector and alternately depress and release the paper-handling change switch
(Figure 5, #1).
When the paper release lever is depressed, the resistance should be 0 ohms. When the lever is released, the resistance should be infinite.
If the resistances are not as shown, replace the paper-handling change switch.
o TESTING THE PAPER FEED MOTOR
Materials Required Digital multimeter
Procedure 1. Turn off the printer and remove the main cover.
