Print Tests

When "PRINT TESTS" is selected from the main Diagnostics menu, the printer's panel displays "PRINT TESTS"
in the header row. Below the header row in vertical order from top to bottom, the panel displays each installed
input source on its own line. "Prt Quality Pages" appears as the very last option in the list.

"[Input Source]" Print Test

After a user selects the input source to test, the panel displays the selected input source in the header row and,
below the header row, presents two testing options: "Single" or "Continuous". Both of these tests will generate a
test page; however, a Single test prints the test page once, while the Continuous test continues printing the test
page until the user presses Stop. During a Single test, none of the panel's buttons are active while the test page
prints. Regardless of the input source selected, the printer always generates a simplexed version of the Print
Test page using its default resolution. However, for either test, the media installed in the selected input source
will affect the content of the test page generated by the printer.
If an input source contains:
•
any size paper, then the printer will generate a page that is similar to the Registration Quick Test, except
that the Print Test version of this page doesn't contain the registration diamonds.
Note: For some paper sizes (e.g. A5), the printer may require more than one sheet of paper when printing
the test page.
If an input source contains:
•
envelopes, then the printer will generate an Envelope Print Test pattern that consists of continuous prints of
each character in the printer's selected symbol set.
Note: During a Continuous test involving an input source containing envelopes, the device will generate
the Envelope Print Test pattern on the first envelope, and then leave each subsequent envelope blank.
While either test prints, the panel displays "[Input Source] Printing...". When a user presses Stop to end a
Continuous test, the panel displays "[Input Source] Canceled". After a Single test has printed or after a
Continuous test is canceled, the panel returns to the screen described at the beginning of this section.

Output Bin 1 (Print Tests)

This test instructs the printer to generate 2 pages and to drop them into Output Bin 1 (the face-up bin on the side
of the printer). The pages printed during this test are in color and contain general information about the printer's
settings. While this test prints, the panel displays "Output Bin 1 Printing...".

Print Quality Pages

This setting enables a user to view the values of a broad range of the device's settings and to test the device's
ability to generate acceptable printed output. Nine pages are printed when the Print Quality Pages test is run.

Hardware Tests

Panel Test

After a user chooses this setting, the printer automatically executes the Operator Panel test application which
occupies the entire display panel. The test application automatically toggles each pixel in the display panel
through every contrast level, beginning with the darkest (e.g. every pixel turned on and as dark as possible) and
ending with the lightest (e.g. every pixel turned off). By implication, this test will show any non-functioning pixels
in the panel, since these will appear as blank spaces during the test's darker stages. The panel test application
executes continuously until the user presses Stop. After this test is canceled, the panel will display the main
"HARDWARE TESTS".
