Manually Printing a Self Test
If you ever question whether the printer is functioning properly, you may have the system print a self-test
page. This printout will cycle through each available character. If the test prints completely and the
printing is legible, this is considered a passed result.
To test the printer through the software, open the Sentinel door and login to the Maintenance Mode.
Press the Test Hardware button then Test Printer. The printer will print a self test.
