Used to check the operations of each fan motor 
and its control circuit.

7

1

Used to set the operating conditions of aging.

6

Used to set the intermittent aging cycle.

8

Used to set the warm-up time display YES/NO.

8

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.

OSA vendor ID display (Application 
Communication Module)

31

OSA vendor ID display (External account module)

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

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
