Voltages Test
This test provides averaged readings for key voltages produced in the Electronics Module. For
the AC line voltage, the value measured is read as either 110 Volts or 220 Volts depending on
whether the measured value is less than or greater than 165 volts. The other AC Line voltage
value is set to 0. A certain amount of variation in the regulated values is typical. These varia-
tions should not exceed 10 percent. The voltage sources for (R12/R13) are unregulated and
may vary by as much as 20 percent. During the test, all possible system loads are turned Off
except the X-Axis Motor. The motor is turned on to draw enough current to maintain power sup-
ply regulation. Any problems with the X-Axis Motor could cause unreliable voltage readings.
The 0 Volt measurements are local ground references and should always be 0 V. Out of range
power supply values can cause unusual power values in many other Print Engine Check tests.
Line Voltage Test
This test provides an evaluation the system’s external power source by checking if the AC
source, and any supplemental wiring or devices, can supply the system adequate power. The
test selectively turns On subsystems to measure the AC line voltage at both min and max load.
Bypass the cool down interval if the system is already cool. An external AC supply of sufficient
capacity should show only a small change in supply voltage. Run this test to verify the AC
source before investigating problems caused by voltage supply problems.
Wiper Alignment Test
This test checks Wiper Blade alignment. This test exercises the Process Drive, Media Drive,
Head Tilt mechanism, and Wiper Assembly to determine Wiper Blade position.
If the Tilt mechanism does not engage, the test will abort with one of the following messages:
•
Printhead unlatch time-out - The Drum Maintenance following error did not exceed 105%
of the Drum Maintenance only max with in the Process Motor tilt drive interval.
•
The wiper stalled during the scan before unlatching the Head Tilt Gear. The most likely
cause is the Wiper Blade is not level causing the high end to contact the drip bib and stall-
ing the wiper axis before unlatching the gear. Other causes could be that the Head Tilt
Gear is jammed (full of ink), or not properly biased (Head Tilt Spring missing or defective).
Also the trip lever could require extra effort to lift (flat spring stronger than usual, rough or
warped engage surface with gear, binding/drag from Head Tilt Solenoid), causing the
wiper axis to stall before contacting the drip bib. Extra drag in the wiper mechanism could
also cause a stall.
•
Process Drive stalled before the Head Tilt Gear was unlatched.
