Troubleshooting Errors That Require a Service Technician 95
SERVICE CALL 00010004
†
Problem
CR motor encoder check error
The CR motor makes small revolutions clockwise and counter-
clockwise. When it turns, the printer checks the encoder output
signals to make sure the motor is turning at the correct speed/
distance. If the encoder doesn’t send the correct signal or output data,
an error occurs.
†
Solution
Make sure there is nothing blocking the carriage. If that does not solve
the problem, check the CR motor encoder connection. If there still is a
problem, try the following.
„
Check the plastic step ruler for soiled areas, obstructions, and
damage
„
Make sure no foreign material or ink tubes (from pump assembly) are
blocking the carriage path (see “Removing the Maintenance
Assembly” on page 143 for reassembly points)
„
Replace the encoder sensor
„
Replace the CR motor
„
Replace the Main Board
