remove the assembly.
System Board Removal
1. Remove the front cover.
2. Unlock the three printhead cable connectors and disconnect the
printhead cables from the system board.
3. Disconnect the other cables from the system board.
4. Gently release the tension on the encoder strip by flexing the
encoder strip tensioner and remove the encoder strip from the
left side only.
5. Remove the three screws securing the system board to the
carrier frame and remove the system board. Note the routing of
the paper feed motor cable. Pull the EOF flag out of the sensor

Note: When replacing the system board, the head to head and
bidirectional printing alignments will be reset to factory defaults. The
user, through the Printer Control program, is directed to perform
these alignments. When reinstalling the system board, it is easier to
insert the printhead cables in the three connectors prior to installing
the board.
