Print Tests

The Diagnostic Input Source PRINT TESTS may be used to verify that the printer can
print on media from each of the installed input sources. Each of the installed sources is
available as a selectable option within the PRINT TESTS menu. For each source, the
user has 2 choices:
•
•
The content of the Print Test page varies depending on the media installed in the selected
input source. If a source is selected that contains paper (that is letter, legal, and so on),
then a page similar to the Quick Test page is printed. However, it does not contain the
Print Registration diamonds. If a source is selected which contains envelopes, then an
Envelope Print Test pattern is printed. This pattern only contains text, which consists of
continuous prints of each character in the selected symbol set.
If Continuous is selected, all sources printing with paper sizes print the same page
continuously until the test is stopped. If Continuous is selected for a source which
contains envelopes, then the envelope print test pattern is printed on the first envelope
and subsequent envelopes are blank.
Note: The Print Test page can be printed on any paper or envelope size. However, more
than one sheet of some media sizes (A5 for example) may be required.
Note: The Print Test page is always single-sided, regardless of the Duplex setting or the
presence of the duplex unit.
While the page is printing the following message is displayed. The Power indicator also
blinks while the page is printing.

If Single is selected, no buttons are active while the Print Test page is printing. However, if
Continuous is selected, Return or Stop can be pressed to cancel the test. While the test
is being cancelled, the following message is displayed.

Note: <input source> represents the input source selected for the Print Test. One of the
following sources is displayed: Tray 1, Tray 2, Tray 3, Tray 4, Tray 5, MP Feeder, or
Envelope Feeder.
Note: The value of the <media width> field is displayed once the printer narrow media
sensor has determined whether the media used for the Quick Test is narrow or wide. An
N
Single (print the Print Test page once),
Continuous (continue printing the Print Test page until Return or Stop is pressed).
