(10) Remove the grounding screw from the underside of the printer base unit.
(11) Remove two screws from the PCB bracket and take it out.
NOTE: When removing the PCB bracket, take care not to drop the grounding spring L.
n n Reassembling notes
• When setting the grounding spring L back into place, position the end of the spring within the
semicircle as shown above.
• When securing the main PCB with screws, align its left and front edges with the PCB bracket
and the positioning ribs as illustrated on the previous page.
• If the main PCB is replaced with a new one (not with a used board), powering on the machine
at the first time from the replacement will make the ERROR and PAPER LEDs flash at 0.5-
second intervals, indicating that the machine has automatically entered the in-process
inspection mode.
To exit from this mode, press the COPY, FEED, COPY ALL, FEED, COPY ALL, and COPY
keys in this order quickly. The ERROR and PAPER LEDs will go off. If these LEDs remain
flashing, turn the machine power off and then on and perform the same exit procedure.
• After replacement of the main PCB, it is necessary to set scanning compensation parameters
stored in the EEPROM and customize the EEPROM for the page length.
- Setting scanning compensation parameters
If both the printer and copyboard are brought to the service station, set the scanning
compensation parameters (Function code 55) as described in Subsection 4.3.1.
If only the printer is brought to the service station, make automatic setting of the scanning
compensation parameters (Function code 02) as described in Subsection 4.3.3.
- Customizing the EEPROM
Customize the EEPROM for page length according to machine models (Function code 32) as
described in Subsection 4.3.7.
