Notes:
For ease of assembly, install the Printhead and Motor Cables first, then install the optional
Media Width Cable.
Connectors for cables are polarized. The connectors will only fit in one direction. Do not
try to force the connectors in place.
Flex cables install in zero insertion force (ZIF) connectors. Pull the connector open, insert
the cable, and close the connector to retain the flex cable.
Dress all cables away from mounting bosses so they won’t get pinched during the next as-
sembly steps.
4. Set the Compatibility Switch per PCC digit 10:
If PCC digit 10 = 0, set SW1 to NORMAL CCW (turn fully counterclockwise ).
