replace the engine

it obtains the settings
from the other board.

both are new and
replaced at the same
time.

USB port service check

1.
Perform a print test to make sure the printer prints correctly. Verify that the indicator light is on, then print
the menu settings by Menu Settings Page from the Reports Menu in the menus.
2.
Be sure the printer USB cable is designed for bidirectional printing.
3.
Be sure the user's application is set up correctly.
4.
If the internal print test page prints correctly, the user's application/printer driver is set up correctly, and the
USB cable is installed, but the printer still fails to print on command from the host computer, then replace
the controller board.
5.
Check the USB cable for continuity.
