SERVICE TABLES AND PROCEDURES
SERVICE RAM ADDRESSES
8002DC(H) - Fusing unit failure
When a service call was caused by a fusing unit failure (code 02)
When a fusing error occurs, the contents of this RAM are changed to 02. After fixing the prob-
lem, reset the data at this address to 00(H), then restart the machine to clear the service call.
(Refer to address 8002F9(H) for other hardware failures.)
8002DD(H) - Excessive jam alarm
Bit 3: Scanner excessive jam alarm
Bit 4: Printer excessive jam alarm
Either or both of these bits will change to 1 when an excessive jam alarm occurs. Reset each
bit to 0 when you have solved the problem. The machine will not be able to detect excessive
jams in future if you do not reset these bits.
8002F9(H) - Details of the service call (hardware error)
02(H): Fusing unit failure
22(H): Laser power is out of the specified range
31(H): Mirror motor error
51(H): Fan motor error
61(H): Unexpected printer error. (Printer Ready signal is not received.)
62(H): Unexpected printer error. (Valid signal is not received.)
When a service call was caused by a fusing lamp failure (codes 02):
The same code is stored at address 8002DC(H).
After fixing the problem, reset the data at address 8002DC(H) to 00(H), then restart the ma-
chine to clear the service call.
When a service call was caused by another hardware failure:
If the problem remains after restarting the machine (power off/on), fix the hardware problem.
The service call condition is cleared after power on.
