Troubleshooting Outline 74
SERVICE REQ. 00010006
o Problem
CR motor overcurrent - Feedback from the CR motor (IC33) driver’s 10-pin
output (Sense signal) indicates that the PF motor’s current is irregular.
o Solution
n Replace the CR motor
n Replace the Main Board
SERVICE REQ. 00010007
o Problem
CR in-position time-out - The in-position time is the amount of time the
printer waits to make sure the carriage is not moving when the carriage
comes to a stop. The linear encoder is activate for the predetermined “in-
position time” and if the encoder sends a pulse, this means the carriage is
moving even though it is supposed to be at a full stop, this generates an
error.
o Solution
n Replace the CR motor
n Replace the Main Board
SERVICE REQ. 00010008
o Problem
Servo interrupt watchdog time-out error due to motor-drive control related
error
o Solution
n Replace the Main Board
SERVICE REQ. 00010009
o Problem
System interrupt watchdog time-out error due to sensor-related error
o Solution
n Replace the Main Board
SERVICE REQ. 0001000A
o Problem
CR origin sensor malfunction - CR home position sensor malfunction
o Solution
Self-diagnostic Function: Check “CR Home Position” in “Inspection:

SERVICE REQ. 0001000C
o Problem
PG origin sensor malfunction (may indicate PG motor malfunction)
o Solution
Check the sensor surfaces for adhesion of ink or soiling, etc. which might
hinder sensor operation. If there is no trouble, and the error cannot be
canceled, check the SLID home position sensor (Self-diagnostic function:
Check “Head Slide” in “Inspection: Sensors.”)
n Replace the PG sensor
n Replace the Main Board
SERVICE REQ. 0001000D
SERVICE REQ. 0001000E
o Problem

switch) located at either end of the cover shaft is malfunctioning.
n (00): right sensor (HP side)
n (01): left sensor
o Solution
Make sure the sensor(s) are properly installed. If that does not solve the
problem, check the cover open sensor connection. Self-diagnostic
Function: Check “Covers” in “Inspection: Sensors.”
n Replace the malfunctioning cover sensor
n Replace the Main Board
