Self-diagnostic
If the number of PCB in which an error occurred is more than one (2)
The communication errors occur. Additionally prepared ARCNET cables are connected.
Diagnosis example: (Determining the failure location using the ARCNET cable)
1. Connect an additional ARCNET cable to the Printer I/F Main PCB to connect it directly to the processor control PCB, then
execute the ARCNET Self-Diagnostic program again.
If an error does not occur either in the
processor control PCB or Printer I/F Main PCB
It can be judged that both the processor control PCB and the Printer I/F Main PCB are normal.
NOTE
• An error occurs in the laser control PCB and in the printer control PCB.
• Confirm the same with the laser control PCB or the printer control PCB to narrow down the failure location.
If an error occurs in the
processor control PCB and Printer I/F Main PCB
It can be judged that the cause of failure lies in the processor control PCB or in the Printer I/F Main PCB.
1. Connect an additional ARCNET cable to the Printer I/F Main PCB to connect it directly to the printer control PCB, then
execute the ARCNET Self-Diagnostic program again.
If an error does not occur either in the printer control PCB or in the Printer I/F Main PCB
It can be judged that the cause of failure lies in the printer control PCB.
Confirm the connection status of the connector of the printer control PCB, then, if no problem is found, replace the printer
control PCB. ☞68100
