the failure. The following is a list of failure codes:
•
Cover open.
•
Cartridges NOT removed.

belt tracked to the rear. Install the shim to the font if the belt tracked to the front. Refer to the instructions
included with the shim for installation.

After installing the shim, run the test, again. If the test fails, rerun several times as the belt needs time to
stabilize. Once the test is successful, reinstall the cartridges and restart the printer.
