Service Diagnostics
Diagnostics Initial Issue
Print Engine Monitor Menu
The Print Engine Monitor tests report current values (temperatures, positions, etc.), and dem-
onstrate the ability to read the values without changing the current state of the system. Some
monitor tests, such as sensors, allow tracking of the values as a state change, either manually
or otherwise. Press any Control Panel key to stop the test.
Test Doc Handler
Subsystem The DADF runs a series of tests to verify the operation of these DADF
functions as previously described:
•
DRAM
• Feed
• Cal Sheet
• Capture
• Lamp
Reset DADF Sub-
system This forces a hardware reset of the Exit Module, Scanner, DADF and
FAX modules.
FAX Modem Menu
Report FW Version Reports the current firmware version.
Report Line Status Reports whether the FAX modem is able to detect a Dial Tone on a
connected phone line.
Test FAX Modem
Subsystem The FAX modem runs an analog loopback test. When the test is
stopped, the error rate (mismatched characters received / characters
sent) is reported.
Reset FAX Modem
Subsystem This forces a hardware reset of the Exit Module, Scanner, DADF and
FAX modules.
Control Panel Menu
Report FW Version Reports the current firmware version.
Monitor Buttons Reports Control Panel button activity. Results are identified by the but-
ton name and the transition (Pressed/Released). The test ends when
there have been no button presses for 10 seconds.
Exercise Display Cycles the Backlight Off then On to verify pixels and operation. After
the test ends, the display settings are backlight maximum, contrast is
minimum, and the pixel background is clear.
Exercise LEDs Exercises each Control Panel LED by turning On, flashing, then turn-
ing Off. The LEDs are activated beginning with the upper right most
LED and moves from top to bottom and left to right until all LEDs have
been activated. The pattern repeats. As each LED is activated, the
LED name is displayed. After termination all LEDs are off.

Test Description Results
Sensors Monitors all mechanically activated sen-
sors in the print engine, except the front
panel buttons. When a state change is
detected it is reported on the display. The
state change reports scroll up as new ones
are added. If the sensor transitions several
times very fast (too fast to do by hand), the
transition is reported as a bounce. State changes are reported as:
•
H = Open or de-actuated
• L = Closed/Present/Actuated
Encoders Monitors these analog sensors:
•
Tray 1 width sensor
• Y-Axis Motor encoder
• Media Drive Motor encoder
• Process Drive Motor encoders
These sensors are monitored:
•
Tray 1 Media Width
• Y-Axis Position
• Media Path Motor Position
• Process Motor Position
Temps Monitors each of the thermal sensors.
Shows the current thermal control setpoint
(first value) and the current sensor temper-
ature (second value). Abbreviations used:
•
LJ = Left Jetstack
• RJ = Right Jetstack
• RE = Reservoir
• DR = Drum
• PH = Preheater
• IM = Ink Melter 1, 2, 3, or 4
Heaters Monitors each of the heaters and shows if
the heater is currently enabled (first value)
and what percentage of maximum power is
currently allocated (second value). Abbreviations used:
•
LJ = Left Jetstack
• RJ = Right Jetstack
• RE = Reservoir
• DR = Drum
• PH = Preheater
• IM = Ink Melter 1, 2, 3, or 4
Line Voltage Monitors the line voltage seen by the
power supply. Reports the minimum and
maximum values seen during the monitor-
ing period. Fast line voltage spikes are not
reported. Helps to evaluate the AC supply,
such as line voltage sags do to the start up
of adjacent equipment. You can run this
test overnight to record supply voltage set-
tings.
Tests results are reported as:
•
Minimum
• Now
• Maximum
