SERVICE RAM ADDRESSES
8002AA(H) - Peak hold control during the scanning (only text mode)*
If the original contains solid black data on the top of the page, this data may not be scanned as
a black image due to peak hold control. Set this bit to 1 to turn off peak hold control. (initial set-
ting 0)
NOTE: The scanned image tend to become darker when the peak hold control is turned off.
Bit 0 to 5: Not used
Bit 6: Copy mode 0: on, 1: off
Bit 7: Fax mode 0: on, 1: off
80032C(H) - Fusing unit failure
When a service call was caused by a fusing unit failure (code 0X)
When a fusing error occurs, the contents of this RAM are changed to 0X. 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 8003A4(H) for other hardware failures.)
80032D(H) - Excessive jam alarm
Bit 3: Scanner excessive jam alarm1: An alarm has occurred
Bit 4: Printer excessive jam alarm1: An alarm has occurred
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.
80033C(H) - Print top margin (standard paper cassette)
800341(H) - Print top margin (optional cassette)
800342(H) - Print top margin (bypass feeder)
800346(H) - Print left margin (standard paper cassette)
80034B(H) - Print left margin (optional cassette)
80034C(H) - Print left margin (bypass feeder)
Refer to section 6.11 for details.
8003A4(H) - Details of the service call (hardware error)
0X(H): Fusing unit failure
1X(H): Charge corona unit failure
21(H): Laser power is out of the specified range
3X(H): Polygonal mirror motor failure
4X(H): Main motor failure
71(H): Home position not detected in book scanner mode
When a service call was caused by a fusing unit failure (codes 0X):
The same code is stored at address 80032C(H).
After fixing the problem, reset the data at address 80032C(H) to 00(H), then restart the machine
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.
8003B0(H) - Initial Toner Supply
Bit 3: Initial toner supply 0: Off, 1: On
Whenever the development unit is replaced, do the following procedure.
1. Make sure that the drum, CTM, and the new development unit are correctly installed.
2. Turn on the machine and change this bit to 1.
3. Turn off the machine.
4. Turn on the machine. The machine starts filling up the empty development unit hopper with
new toner. (This bit is reset to zero automatically.)
5. Make test copies or test patterns to check the print quality.
