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 92 and check that the values are
within the given limits.
2. Clean the Encoder Strip
See Clean the Encoder Strip on page 467.
3. Perform the Scan-Axis Test to obtain further information on the problem
Scan Axis test
on page 92.
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 92 and check that the values are
within the given limits.
2. Clean the Encoder Strip
See Clean the Encoder Strip on page 467.
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:
●
Ink Smearing on the Paper.
●
Printhead crashes against the Paper.
●
Roll Paper loading problems (low probability).
Banding at variable extreme environmental
conditions
NOTE: This problem is only applicable if the OMAS is disabled.
Since the Accuracy Calibration has been done at normal environmental conditions, printing in extreme
environmental conditions will cause banding because the advance of the Drive Roller does not
