AL-2030/2040CS/2050CS SIMULATION, TROUBLE CODES 10 - 3
1 06 Aging of mirror scanning [Function]
When [ENTER]/[START] key is pressed, the mirror base performs full scan at the speed of the
set magnification ratio.
During operation, the set magnification ratio is displayed.
After 3sec, the mirror base performs full scan again.
∗ When [ENTER]/[START] key is pressed once, the ready lamp remains OFF.
The mirror home position sensor status is displayed on the "Drum replacement required lamp
(or the copy mode indicator for the AL-2050CS)." (The lamp is ON when the mirror is in the
home position.)
During aging, the copy lamp is ON.
[Operation] (AL-2050CS only)
The operation is similar to simulation 1-01.
2 01 SPF/RSPF aging operation [Function]
When [ENTER]/[START] key is pressed, the set magnification ratio is obtained. For the SPF, the
single-face document transport is performed. For the RSPF, the duplex document transport is
performed.
However, the operating conditions don't matter and the operation is not stopped even in case of
a jam. Also the magnification ratio is displayed on the LCD/display.
[Operation] (AL-2050CS only)
The operation is similar to simulation 1-01.
02 SPF/RSPF sensor status
display
[Function]
The ON/OFF status of the SPF/RSPF sensors can be checked with the LCD/LED.
When a sensor is ON, the sensor name is displayed on the LCD/LED.
[Operation] (AL-2050CS only)
03 SPF/RSPF Motor ON [Function]
When [ENTER]/[START] key is pressed, the motor rotates for 10sec at the speed correspond-
ing to the set magnification ratio.
[Operation] (AL-2050CS only)
The operation is similar to simulation 1-01.
06 Resist clutch ON (SPF)
(AL-2030/2040CS only)
When the [START] key is pressed, the SPF resist clutch (SRRC) repeats ON (500 ms) and OFF
(500 ms) 20 times.
08 RSPF paper feed solenoid
operation check
(AL-2050CS only)
[Function]
The RSPF paper feed solenoid (SPUS) repeats ON for 500ms and OFF for 500ms 20 times by
the use of the solenoid drive control Bios.
[Operation] (AL-2050CS only)
09 RSPF reverse solenoid
operation check
(AL-2050CS only)
[Function]
The RSPF reverse solenoid (SPFS) repeats ON for 500ms and OFF for 500ms 20 times by the
use of the solenoid drive control Bios.
[Operation] (AL-2050CS only)
