6-16 Phaser 600 Color Printer
The print is wrinkled
1.
Check the fuser for obstructions. Inspect the stripper fingers for
damage that might snag a print as its fingers strip the paper off the
drum into the fuser. Odd types or weights of media may not be
suitable for the printer and therefore may wrinkle as they are
processed.
2.
A print with heavy printing on only one side of the print may wrinkle.
3. Ensure that the fuser is not excessively oiled. Run three to five sheets
of paper through the printer.
1. Clean the ink load chutes.
2.
Test the sensors and motors using the PC-based diagnostics. Refer to
"PC-based diagnostics" on page 6-26.
3. Check the ink load flags to ensure that they are properly positioned.
Refer to the Chapter 9 topic "Ink loader sensor flag adjustment" on
page 9-13.
4.
Ensure the printhead is properly positioned to receive ink sticks.
Refer to the Chapter 9 topic "Ink stick load position" on page 9-14.
Customer-performed steps to recover faulty jets
1. Run the Utilities menu item Clean Head to run a printhead cleaning
cycle.
2. Print a test print (Utilities menu item Test Print) and examine it.
3.
If the problem persists, run the Clean Head cycle again to run another
cleaning cycle
4. Inspect the maintenance station wiper. It should be clean, straight,
and have no nicks or cuts. A dirty or damaged wiper cannot properly
clean the face of the printhead.
5.
Clean the wiper with an alcohol-moistened foam swab. Never scrape it
with a tool or with your fingertip. Following a printhead cleaning cycle
the wiper is warm and the ink wipes off easily.
