PRINT TESTS

Print Tests (input sources)

This test determines if the printer can print on media from any of the paper input sources. Each of the installed
sources is available within the Print Tests menu.
The content of the test page varies depending on the media installed in the selected input source.
•
If a source is selected that contains paper, then a page similar to the Quick Test Page is printed and 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 contains only text, which consists of continuous prints of each character in the selected symbol set.
•
If Continuous is selected, then the same page prints continuously from the selected source until you press
Stop. If Continuous is selected from a source which contains envelopes, then the envelope print test
pattern is printed on the first envelope, and the rest are blank.

option.
