AL-2030/2040CS/2050CS SIMULATION, TROUBLE CODES 10 - 30
5. Trouble codes
A. Trouble codes list B. Details of trouble codes
64 01 Self print [Function]
The status of the optical section is ignored and printing of one page is made. Also when the
print command is received from the host, printing is made.
When this simulation is executed, warm-up is performed and the ready lamp is lighted. (Since,
however, the scanner is disabled, initializing is not made.)
Enter the code number and press [ENTER]/[START] key to start paper feed from the selected
cassette and print in the selected pattern.
* For 4 – 99, flip.
[Operation]
The operation is similar to simulation 26-02.
67 50 USB receive speed
adjustment (USB1.1)
(AL-2030/AL-2040CS only)
Used to set the limitation on the print data receive speed of USB2.0 (Full speed) port (USB port
on the machine).
→ When print images from USB2.0 (Full speed) port are disturbed, change the setting and try
again.
When this simulation is executed, the currently set code number is displayed.
Enter the code number corresponding to the adjustment value, and press [START] key to
change the setting.

Details of trouble
E1 00 Content IMC communication trouble
Detail An abnormality occurs in communication
between the CPU and the IMC.
Cause IMC abnormality
IMC memory defect/data abnormality
Check
and
remedy
Replace the MCU PWB with new one.
10 Content IMC trouble
Detail An abnormality occurs in the IMC.
Cause USB chip error/CODEC error on the IMC.
Check
and
remedy
Replace the MCU PWB with a new one.
13 Content IMC flash ROM error
Detail An abnormality occurs in the IMC flash
ROM.
Cause IMC abnormality
Check
and
remedy
Replace the MCU PWB with a new one.
If downloading of the program is abnormally
terminated, it may cause an error. Download
the program again to avoid this.
81 Content IMC communication interface error (Parity)
Detail A parity error occurs in communication
between the CPU and the IMC.
Cause IMC abnormality
IMC memory defect/data abnormality
Check
and
remedy
Replace the MCU PWB with new one.
