1. Open the Window and check for any visible obstacles restricting the movement of the Drive Roller. Make
sure that the mylar is not damaged. If there is a wrinkled mass of paper inside the paper path, lift the
Pinchwheels (opening the Rear Door) and clear the obstruction.
2. If this shutdown happens at the end of a Roll of Paper, it could be because the paper is stuck firmly to
the Roll. Lift the Pinchwheels (opening the Rear Door) and pull the paper clear.
3. Replace the spindle if broken.
4. Perform the Paper Drive Test to obtain further information on the problem

on page 84.
Printhead path
When a shutdown occurs in the Printhead path, you will get the message “Switch Power Off / Check Printhead
Path (*). The (*) will be a number, which will give an indication on where the failure occurred.
PWM shutdown
To resolve a PWM shutdown, do the following.
1. Clean Slider Rods and Apply Oil along the complete axis of the Slider Rods. After applying the Oil,
perform the Scan-Axis Test
See Scan Axis test on page 83 and check that the values are within the
given limits.
2. Clean the Encoder Strip
See Clean the Encoder Strip on page 452.
3. Perform the Scan-Axis Test to obtain further information on the problem

Velocity shutdown
To resolve a velocity shutdown, do the following.
1. Open the Window and check for any visible obstacles restricting the movement of the Carriage
Assembly. Try and move the Carriage Assembly manually, checking for smooth and free movement.
2. Check that the Encoder Strip is clean. If necessary, clean Encoder Strip using a damp cloth.
Energy shutdown
To resolve an energy shutdown, do the following.
1. Clean Slider Rods and Apply Oil along the complete axis of the Slide Rods. After applying the Oil,
perform the Scan-Axis Test
See Scan Axis test on page 83 and check that the values are within the
given limits.
2. Clean the Encoder Strip
See Clean the Encoder Strip on page 452.
3. Perform the Scan-Axis Test to obtain further information on the problem

Vacuum suction much lower at high altitudes
At altitudes above 3,000 meters, the vacuum force holding down the paper will be lower, therefore the paper
will not be held in place properly causing:
