WARNING:
Do not replace the
engine board and
controller board at the
same time. Each board
contains the machine
settings. When either of
these boards is new, it
obtains the settings
from the other board.
Settings are lost when
both are new and
replaced at the same
time.
Card
Remove all the option cards from the device.
Install each card individually. Restart the machine after each card is
installed.
Remove the card and repeat the previous step with a different card till all
cards are checked.
When a faulty card is found, replace the card ( p.127 "Option Board
Installation and Removal"). If the error persists after replacing the option
card, replace the controller board ( p.44 "Controller Board Removal").
If there are no errors found testing the cards individually, install the cards on
at a time. Restart the machine after each card is installed.
Cables
If the cards do not trigger an error, check the option card connection cables
for continuity.
USB Port Service Check
1. Perform a print test to make sure the machine 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 machine 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 machine still fails to print on command from the host
computer, then replace the controller board.
5. Check the USB cable for continuity.
