Check the encoder strip for proper installation.
Also, check it for wear, dirt, and grease.
Be sure all printhead connectors and carrier
cables are fully seated. Check the cables for
damage.
If the encoder strip and all connections are okay,
but the carrier still slams the side frame, replace
the system board. Go to the
page 4-15.
Check for worn, loose, or broken parts. Check for
obstructions blocking carrier movement.
Check the carrier belt idler pulley mounting screw.
Loosen the screw and allow the tension spring to
take up any slack in the belt. Tighten the screw. If
the pulley mounting bracket has reached the stop,
replace the carrier assembly. Go to the
