Printhead drive service check
Note: In any steps in this procedure, replace any parts you find to be broken or irreparably loose.
1. Turn off the printer.
2. Locate and remove from the forms paths torn pieces of paper or other foreign material that can cause
forms jams. Also inspect the printhead movement area.
3. Remove the printer covers (see Service position).
4. Inspect the encoder sensor and the encoder strip for cleanliness, damage, or a loose mounting.

5. Inspect the carriage motor and pulley for wear, damage, binds, or looseness. Ensure that the 4 screws
that support the carriage motor are not damaged. Verify that the cooling fan is installed correctly.
To inspect the carriage motor, remove the printhead and loosen the belt clamp to free the belt. Move
the belt to rotate the motor pulley and the idler pulley. If the rotation indicates bearing damage,
replace the idler pulley or the carriage motor.
