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 C186 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 or EEPROM 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.
