Action
Blurred print and voids can be caused by
problems in the transport area. Check the
following:
• Transport belt for wear and full engagement into
the carrier grip.
• Carrier guide rod for wear or dirt.
• Carrier to carrier frame engagement should be
lubricated with grease P/N 99A0394.
Lubricate the carrier guide rod and carrier frame
on both sides where the two top bearing
surfaces ride on the frame.
• Idler pulley parts for wear, damage, or
looseness.
Action
Check the motor for binds, or loose motor pulley.
Disconnect the transport motor J2C from the
system board. Check for approximately 7 ohms
between pins 3 and 4 on the motor cable and for
shorted motor pins. If the reading is incorrect,
replace the engine frame assembly.
If the failure remains, replace the system board.
Check connector J2C on the system board and
check for a approximately 23 V dc pulse between
J2C-1 and ground as the printer goes through
POST. If incorrect, replace system board.
Check the ink carrier assembly.
Clean the carrier rod.
Note: Lubricate the rod and the carrier rod bearing
surface.
