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.
