Serial Wrap tests
The serial wrap tests are used to check the operation of the serial port hardware using a wrap plug. Use Serial 1 Wrap if a serial port is available through PCI slot 1 and Serial 2 Wrap if the serial port is available through PCI slot 2.
To perform the Serial Wrap tests:
1.Disconnect the serial interface cable, and install the serial wrap plug.
2.Select Serial 1 Wrap or Serial 2 Wrap from HARDWARE TESTS.
The power indicator blinks green indicating the test is in progress. The test runs continuously until a maximum number of tests is reached.

P:###### F:####
•P:###### represents the number of times the memory test has passed and finished successfully. Initially 000000 displays with the maximum pass count being 999,999.
•F:##### represents the number of times the memory test has failed and finished with errors. Initially 0000 displays with the maximum fail count being 999,999. Initially only four digits appear, but additional digits appear as needed.
Each time the test finishes, the screen updates. If the test passes, the pass counter increases by 1, however if the test fails, a message displays for approximately three seconds. Once the maximum count is reached, the test stops. The power indicator goes on solid, and the final results display.
To stop the test before completion, press Stop ( 
).The message Serial Wrap x Test Canceled displays, and the printer returns to the HARDWARE TESTS menu.
DUPLEX TESTS
Quick Test (duplex)
This test prints a duplex version of the Quick Test that can be used to verify that the correct placement of the top margin on the back side of a duplex page. You can run one duplexed page (Single), or continue printing
duplexed pages (Continuous) until Stop (
) is pressed. For information about changing the margin, see “Top Margin (duplex)” on page
Note: Before you set the duplex top margin, be sure to set the registration. See “REGISTRATION” on page
The paper you choose to print the page on should be either Letter or A4.
To run the Quick Test (duplex):
1.Select Quick Test from DUPLEX TESTS.
2.Select Single or Continuous.
•The single Duplex Quick test cannot be canceled.
•The printer attempts to print the Quick Test Page from the default paper source. If the default paper source only supports envelopes, then the page is printed from Tray 1.
•Check the Quick Test Page for the correct offset between the placement of the first scan line on the front and back side of a duplexed sheet.
The single test stops automatically when a single duplex sheet is printed, and the continuous test continues until you press Stop (
).
