4.1.2 SC CODE DESCRIPTIONS
ƒ
If a problem concerns a circuit board, disconnect and reconnect the connectors
and then test the machine. Often a loose or disconnected harness is the cause of
the problem. Always do this before you decide to replace the PCB.
ƒ
If a motor lock error occurs, check the mechanical load before you decide to
replace the motor or sensors.
ƒ
When a Level “A” or “B” SC occurs while in an SP mode, the machine cannot
display the SC number. If this occurs, check the SC number after leaving the SP
mode.
ƒ
The machine reboots automatically when the machine issues a Level “D” SC code.
This is done for Level “D” SC codes only.
ƒ

ƒ The main power LED ( ) lights or flashes while the platen cover or ARDF is
open, while the main machine is communicating with a fax machine or the network
