The contents of the print test page vary depending on the media
installed in the selected input source. If a source is selected that
contains paper, legal, letter and so on, a page similar to the quick
test page is printed. However, the page does not contain the print
registration diamonds.
If Continuous is selected, all sources printing print the same page
continuously until the test is stopped. If continuous is selected for a
source containing envelopes, the envelope print test pattern prints
on the first envelope and subsequent envelopes are blank.
Note: The print test page may be printed on any paper or envelope
size, however more than one sheet of some media sizes may be
required. The print test page is always single sided, regardless of
duplex settings or the presence of the duplex unit.
To run the print test page:
1. Select Print Tests from the diagnostic menu.
2. Select the media source.
3. Select Single or Continuous.
If single is selected, no buttons are active during printing. If
continuous is selected, Return or Stop can be selected to
cancel the test.
Note: The power indicator blinks while the page is printing. Check
each test page from each source to assist in print quality and paper
feed problems.
