Tips on preventing jams
You can avoid most paper jams by correctly loading paper and
specialty media.
The following hints can help you avoid paper jams:
Do not load wrinkled, creased, or damp paper. Never mix media types within a tray. Flex, fan, and straighten paper before you load it.
Do not exceed the maximum stack height.
Push all trays firmlyinto the printer after loading them. Make sure the guides in the trays are positioned snugly against
the paper or specialty media.
Do not remove paper trays while a job is printing. Wait for aLoad Paper light sequence before you remove the tray.
Before loading transparencies, fan the stack to prevent sheets
from sticking together. Do not use envelopes that:
Have excessive curl Are stuck together Are damaged in any way Contain windows, holes, perforations, cutouts, or embossing Use metal clasps, string ties, or metal folding bars Have postage stamps attached Have any exposed adhesive when the flap is in the sealed
position
Use only recommended paper. Refer to the Card Stock & LabelGuideavailable on the Lexmark Web site at www.lexmark.com for
more information about which paper provides optimum results for
current printing environment.

Service checks which involve measuring voltages on
the LVPS/HVPS (low voltage power supply/high voltagepower supply board) should be performed with the printerpositioned on its back side.
Note: When you make voltage readings, always use frame groundunless another ground is specified. See Wiring diagram onpage 5-4 for more information.

2. When light stays on, close cover.
3. Wait (approximately 7 seconds) until the printer drive activates.
4. Enter the configuration menu. See Configuration anddiagnostic groups on page 3-1 for more information.
5. Slowly press and release three times until the andlights come on.
6. Press and hold until all the lights flash to initiate print quality
test pages.
Three pages print to help you evaluate print quality. The firstpage has various fonts, the second page is gray, and the thirdpage is black. Once the paper exits into the output bin, theprinter returns to the homestate (four top lights on).
7. Use the test pages to isolate problems such as light or tonerstreaks. See Symptom tables on page 2-44 for solutions to
these problems.8. To exit print quality test pages, turn the printer off.

Blank pages can be caused by adefective printhead assembly,LVPS/HVPS, or controller card.
Printhead errors typically result inprinter service errors. Blank pages typically are caused
by the PC roll not being properlycharged. Try a different PC kit.
Unplug the printer and checkcontinuity between the LVPS/HVPSconnection pads marked OPC andthe corresponding pin inside theprinter.
If there is not continuity, call thenext level of service.
Try a different toner cartridge andPC kit.
