General Troubleshooting 4-39
Tilt Drive
This test drives the printhead tilt mechanism through one cycle to determine if it is controllable
and operating as expected.
R# Definition
Typical
Value Actions
0 Tilt Engage Cap
Position (min)
MFG
Only
Reports the distance from the cap Home
position to the tilt cam engage point.
1 Pre Standby Peak
Location ()
50 to
3500
Reports the distance around the tilt cam from
the tilt engage position to the pre standby
peak. Should be in degrees, but currently units/
scaling are unverified.
2 Pre Standby peak
Magnitude (pm ticks)
-5500 to
0
Reports the pm motor following error at the pre
standby peak location.
3 Post Wipe Peak
Location ()
1000 to
5000
Reports the distance around the tilt cam from
the tilt engage position to the post wipe peak.
Should be in degrees, but currently units/
scaling are unverified.
4 Post Wipe peak
Magnitude (pm ticks)
MFG
Only
Reports the pm motor following error at the
post wipe peak location.
Tray 2, Tray 3, Tray 4, Lift Plate Drive
This test raises the lift plate to verify motion and sensor operation. If the test is requested for a
525-sheet feeder that is not installed, an “Option Not Detected” message is generated.
R# Definition
Typical
Value Actions
0 Tray Configuration MFG
Only
Reports the tray status (present, plate not
lifted, etc.). See Paper Path Status test for a
description of the configuration encoding.
1 Start Peak Power
(watts)
MFG
Only
Reports the highest peak during the first
quarter of the lifting interval.
2 Slack Take-up Time
(sec)
MFG
Only
Reports the interval between the initial power
min (when the plate is not yet engaged), and
the point where the lifting power becomes a
constant.
3 Average Lift Power
(watts)
MFG
Only
Reports the average power over the center ¾
of the lifting interval.
