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

Problem
CR motor out of step - the length of the CR motor’s pulse is too long
or too short compared to the regular pulse.
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
