1

Used to check and adjust the operations of the 
developing voltage of each color and the control 
circuit.

2

Used to check and adjust the operation of the 
main charger grid voltage in each printer mode 
and the control circuit.

6

Used to check and adjust the operation of the 
transfer voltage and the control circuit.

17

Used to check and adjust the operation of the 
transfer voltage and the related circuit. (Transfer 
belt cleaning mode)

9

1

Used to check and adjust the operation of the 
load (clutch/solenoid) in the duplex section and 
the control circuit.

2

Used to check the operations of the sensors and 
detectors in the duplex section and its control 
circuit.

10

1

Used to check the operations of the toner motor 
and the related circuit.

13

0

Used to cancel the self-diag "U1" trouble. (Only 
when FAX is installed.)

14

0

Used to cancel excluding the self-diag U1/LCC/
U2/PF troubles.

15

0

16

0

Used to cancel the self-diag U2 troubles.

17

0

Used to cancel the PF troubles (when the copy 
inhibit command from the host computer is 
received).

21

1

Used to set the maintenance cycle.

22

1

Used to check the print count value in each 
section and each operation mode. (Used to check 
the maintenance timing.)

2

Used to check the total numbers of misfeed and 
troubles. (When the number of misfeed is 
considerably great, it is judged as necessary for 
repair. The misfeed rate is obtained by dividing 
this count value with the total counter value.)

3

Used to check misfeed positions and the misfeed 
count of each position. (If the misfeed count is 
considerably great, it may be judged as 
necessary to repair.)

4

Used to check the trouble (self diag) history.

5

Used to check the ROM version of each unit 
(section).

6

Used to output the list of the setting and 
adjustment data (simulations, FAX soft switch, 
counters).

7

Used to display the key operator code. (This 
simulation is used when the customer forgets the 
key operator code.)

8

Used to check the number of use of the finisher, 
the SPF, and the scan (reading) unit.

9

Used to check the number of use (print quantity) 
of each paper feed section.

10

Used to check the system configuration (option, 
internal hardware). 

11

Used to check the use frequency (send/receive) 
of FAX. (Only when FAX is installed)

12

Used to check the SPF misfeed positions and the 
number of misfeed at each position. (When the 
number of misfeed is considerably great, it can be 
judged as necessary for repair.)

13

Used to check the operating time of the process 
section (OPC drum, DV unit, toner bottle).

19

Used to check the values of the counters related 
to the scan mode and the internet FAX mode.

23

2

Used to check the trouble history of paper jam 
and misfeed. (If the number of misfeed and 
troubles is considerably great, it may be judged 
as necessary to repair.)

80

Used to check the operations of the sensors and 
detectors in the paper feed and transport section.

24

1

Used to clear the misfeed counter, the misfeed 
history, the trouble counter, and the trouble 
history. (The counters are cleared after 
completion of maintenance.)

2

Used to clear the number of use (the number of 
prints) of each paper feed section.

3

Used to clear the number of use of the finisher, 
SPF, and the scan (reading) unit.

4

Used to reset the maintenance counter.

5

Used to reset the developer counter. (The 
developer counter of the DV unit which is installed 
is reset.)
