Troubleshooting Guide
3-4
Cause Point to check Action
C4
Check the carriage stop position. If the carriage is at the leftmost position, the purge
unit may be faulty (check the lock pin).
T12 (P4-18)
C1
Check the carriage load (move the carriage by hand to make sure that it is not heavy
or foreign matter is not stuck in it).
Flow 1
C3
Check images to see if the edges do not have stepped uneven densities in the paper
feed direction.
T01 (P4-1)
C2
Restart the printer. and check the behavior of the firmware and the carriage (upgrade
the firmware if it is Ver. 1.31 or any earlier release).
Flow 2
C3 Check to see if the carriage encoder is properly installed. T13 (P4-19)
C3 Check to see if the carriage encoder is not faulty. T01 (P4-1)
C4 The purge unit carriage lock pin is up but the carriage is not at the capping position. T12 (P4-18)

Carriage drive load
error
C1

Improper carriage belt tension (jumping teeth)
Residual jam slips in the printer
Carriage motor
drive at electrical
fault
C2
Drive signal/voltage error
Poor connector contact/wiring
Faulty motor
Faulty carriage
encoder sensor
C3
Soiled or flawed carriage encoder, or improper mounting position/tension
Soiled or faulty carriage encoder sensor
Disconnection or partial disconnection in the flat cable, or poor connector contact
Failure causes
Faulty purge unit C4
Carriage lock pin not released, capping operational failure or position detection
failure
Rail cleaner
iPF700 Series iPF8000 Series
Rail cleaner
Unlock the purge unit and move it
by hand
Checking for load during carriage travel
Hits something
Noticeably heavy
Foreign matter inside (cutter, cleaning
brush, etc.)/bearing out of position
Clean the soiled rail, replace the rail
cleaner/faulty bearing
Faulty belt Broken spring hook, jumped belt tooth
