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).

o 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.
