Lexmark C912 Service Manual - Page 142

5055-xxx Problem Action (continued) Color fades with fuzzy, poorly defined edges. Toner adheres to the back of the page. Ensure the absorption roll/charge roll on the belt is securely seated. The black plastic T-shaped bushing should both be below the flap on the right side of the belt. A poorly seated roll can cause both skewing of the paper and problems with the magenta print. Check that the top cover is firmly closed on the printer. If the cover is not closed completely, the LED may be out of focus and allow light print on the bottom of a letter size page. Close the cover firmly and test. Print the quality pages in the Diagnostics Mode (under Print Test, Print Quality Pages). This often identifies the color that has a problem. If you switch the toner cartridges and the problem also changes color on the test pages, the problem is in one of the cartridges. Replace the proper color cartridge. Remove the fuser oil roll and wipe it with a dry, lint-free cloth, and clean the transfer belt. If there still is a problem, go to "Periodic dirt" on page 2-97. Quality of printed transparencies is inadequate. Be sure you're using the recommended Lexmark transparencies. Be sure you have selected the correct paper weight setting for the media you are using. When printing transparencies, always set the Paper Type to Transparency. Avoid getting fingerprints on transparencies before printing. 2-92 Service Manual
