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
