Troubleshooting Procedure
Step
Questions and Actions
Yes
No
1
1.
Check for obstructions around the printhead.
Look for ink shards in gears of the tilt drive.
2.
If the printhead is obstructed, remove any
obstruction from the system and reboot.
3.
Did this fix the problem?
Complete.
Go to Step 2.
2
1.
Ensure the wiring around the printhead is
routed properly.
2.
Is the wiring blocking the printhead?
Re-route all
wiring to the
printhead.
Go to Step 3.
3
1.
Remove the waste tray and printhead and
look for ink build-up in the system.
2.
Is there ink build-up any where in the
system?
Clean any ink or
debris which
may be
restricting
movement of
the drive train or
printhead.
Go to Step 4.
4
1.
Check the process gearbox for damage.
2.
Ensure the gears are correctly aligned. See
see "Homing the Process Gear Drive Train"
on page 6-8.
3.
Is the process gearbox damaged?
Replace the
process
gearbox.
Go to Step 5.
5
1.
Check the X-axis motor connector for
damage.
2.
Run the
X-axis Motor
test to check the
X-axis motor current.
3.
Did the test fail?
Replace the X-
axis motor.
Go to Step 6.
6
1.
Run the
Tilt Drive
test.
2.
Did the test fail?
Replace the process gearbox.
