AL-2030/2040CS/2050CS SIMULATION, TROUBLE CODES 10 - 7
9 04 Duplex motor rotation speed
adjustment
(AL-2040CS/2050CS only)
[Function]
When this simulation is executed, the currently set value is displayed.
Enter the adjustment value with [ ] [ ] key (or [Numeric] key for the AL-2050CS) and press
[ENTER]/[START] key. The entered value is stored and the machine goes into the sub code
entry standby mode. The greater the set value is, the higher the speed is. The smaller the set
value is, the lower the speed is.
(Setting range: 1 - 13, Default: 6)
[Operation]
10 Toner motor aging [Function]
When [ENTER]/[START] key is pressed, the toner motor is rotated for 30sec.
After completion of this process, the machine goes into the main code entry standby mode.
[Operation] (AL-2050CS only)
14 Cancel of troubles other than
U2
[Function]
Used to cancel troubles other than U2.
∗ Cancel troubles such as H trouble which writes data into EEPROM, and perform hardware
reset.
[Operation] (AL-2050CS only)
16 Cancel of U2 trouble [Function]
Used to cancel U2 trouble.
When [ENTER]/[START] key is pressed, check sum of the total counter in the EEPROM is
rewritten and hardware reset is made.
[Operation] (AL-2050CS only)
22 04 JAM total counter display [Function]
The JAM total counter is displayed.
