Replace the short flexible cable or the sub logic
board as necessary.
If there is still a problem, replace the operator
panel. If that does not fix the problem, re-install
the old operator panel and replace the main
logic board. If you replace the main logic
board, reset the "Bidirectional Print
Adjustment" on page 4-5.
