PER Not Received Error
RAPI-PER command was not received from the controller within the specified time
(120 sec.) after RAPI-PES (preparation request for image transmission) is issued.
• Electrical noise
• Controller board (PCB15) defective
Check if the SC occurs by turning the main power OFF then ON for ten times. If
the SC occurs again, do the following steps. Check if the SC reoccurs by cycling
the power after each step.
1. Check the engine and controller firmware, and update the firmware to the
latest version.
2. If the SC is issued during printing or during receiving fax documents, replace
the controller board (PCB15). If the SC is issued during copying, check the DF
and IOB (PCB17) connection.
