4.2.2 Bidirectional Print Alignment Adjustment
This section describes the procedure for adjusting the bidirectional print alignment, required after
mechanism repair. This procedure is also necessary if you replace the main board assembly or EEPROM,
because the adjusted value is written to the EEPROM on the C165 MAIN board. You can perform the
adjustment from the Settings Diskette, using the control panel, or with a remote utility. This section
describes the adjustment procedure with the Settings Diskette first, and then describes the adjustment
procedure using the control panel.
Notes: When the main board is replaced, reset the Factory Settings first, then perform the
bidirectional adjustment.
Do not perform the Bi-d adjustment if the input voltage is fluctuating heavily.
