Carrier service checks
Symptom Action
• The carrier slams
against the side
frame.
• There is no carrier
movement.
• Check the encoder strip for proper installation or contamination. Clean as
possible.
• Check the carrier cable connectors on the system board. If connectors are
okay, then replace the system board. See
“System board with media sensor,
cable, and spring removal” on page 4-21 . If that does not fix the problem,
then replace the print engine. See “Print engine removal” on page 4-25 .
Poor print quality Be sure that the All-In-One contains good print tanks.
Be sure the print tank nozzle plate is clean. Clean with a soft cloth.
Ink smudging and smearing can be caused by paper problems or problems in the
paper feed area. Check for:
• Correct type of paper
• Curled or wrinkled paper
• Paper path obstructions
• Feed roller wear or looseness
• Worn gears or binds
If the paper feed roller or gears are defective, then replace the All-In-One.
Blurred print and voids can be caused by problems in the carrier transport area. Check
the following:
• Carrier transport belt for wear
• Idler pulley parts for wear, damage, or looseness
• Carrier guide rod for wear or dirt. If the rod is dirty, then clean and lubricate it.
The carrier to carrier frame engagement should be lubricated with grease P/N
40X0179.
If the carrier transport belt is worn, then replace the print engine. See
“Print engine
removal” on page 4-25 .
If the idler pulley parts are defective, then replace the print engine. See “Print engine
removal” on page 4-25 .
