Evaluate results: When the test is complete, the following screen is displayed: Test Complete Code OR Test Failed Failure Code= If the test is successful, the pass code will be a number between -250 and +250. Do not install a shim. If the test fails, then a fail code will be a number between 0 and 200 and a message indicates the cause of the failure. The following is a list of failure codes: Failure Code 01 02 03 04-100 103 104-200 Results Cover open. Some cartridges NOT removed.

Three or fewer revolutions before test ended. Belt tracked to rear. Probably never displayed. 100 or more revolutions when test ended. Belt tracked to rear. 4. Exit the test; press any button. 5. Verify the failure code by comparing the belt position to the initial position. Install the shim to the rear if the belt tracked to the rear. Install the shim to the font if the belt tracked to the front. Refer to the instructions included with the shim for installation. 6. After installing the shim, run the test again. If the test fails, rerun several times as the belt needs time to stabilize. Once the test is successful, reinstall the cartridges and restart the printer. Printhead Inst The purpose of this test is to print a page that aids in the mechanical alignment of a printhead. This test should not be used independently of the mechanical alignment. See "Mechanical alignment" on page 4-72. 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 only contains text, which consists of continuous print of each character in the selected symbol set. • If Continuous is selected, all sources printing with media sizes prints the same page continuously until the test is stopped. 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. The Print Test page always prints single-sided, regardless of the Duplex setting or the presence of the Duplex option. To run the Print Test: 1. Select PRINT TESTS from the Diagnostics mode. 2. Select the paper source from the menu. 3-14 Service Manual
