Print Engine Tests: In general, diagnostic testing is assumed to be done with the system in a
“diagnostic configuration.” This means the following applies:
• Doors are closed unless instructed otherwise.
• The print engine is thermally warm (at nominal printing temperatures).
• All axis’s are or have been moved to their HOME position (run MECH INIT function).
• Trays are inserted and contain A/A4 media, unless instructed otherwise.
The tests may also be performed with the system operating at less than normal printing tem-
peratures, but may produce slightly less typical results.
NOTE: While the heaters are On, the Y-Axis is turning (to keep the Drum heating even), and
the Drum Fan may be active. The Exercise Menu -> Heaters -> All Off function disables ther-
mal regulation if access to these areas is necessary. The background thermal regulation is
reactivated by the Exercise Menu -> Heaters -> All On function if the system is still warm
enough. Turning off a single heater does NOT disable this function and the heater may be
turned back on following the next check test or reboot. The Electronics Module Fan is always
active.
Test Selection Diagnostics Mode:
The Test Selection mode provides limited access to diagnostic tests, and is typically used dur-
ing remote customer support activity where the customer is being directed to run the test and
report results by a support representative.
NOTE: Before running any diagnostic test, prepare the system according to test requirements.
To enter Test Selection mode from Customer mode and display the Test Selection screen:
1. Select Information -> Troubleshooting -> Service Tools from the Control Panel.
2. Scroll down to Enter Diagnostics and press the OK button.
When the system transitions from Customer mode into Test Selection mode, the initial Control
Panel display is the Test Selection screen as follows:
Diagnostics Menu 19.212.0
Test: 000 None Selected
The Diagnostics Menu revision number identifies the system and diagnostics firmware ver-
sions. The first two identify the system firmware version. The last digit identifies the Diagnostics
Firmware version. The Test number (000) is entered using the Up or Down buttons. The cur-
rently selected Test appears next to the number. Run the test by pressing the OK button. At
that point, the display changes to the name of the test, followed by a series of status messages
providing a general idea of the current test activity. When the test completes, the display
changes to display the results.
In some menus the subsystems are identified as follows:
• FP - Control Panel Module subsystem
• EM - Exit Module subsystem
• SM - Scanner Module subsystem
• DH - Doc Handler Module (DADF) subsystem
• FM - FAX Module subsystem
Test 000 is inoperative and causes no response if the OK button is pressed. To return to Cus-
tomer mode, run test 001. Ta bl e 1lists the available tests.
