5021-0XX 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.
