Also check that the Rewinder Motor moves easily (without friction) with the printer turned off.
Maintenance cartridge path
Open the right door of the printer and check for any visible obstacles restricting the movement of the
Service Station. Manually move the Service Station, checking for smooth and free movement.
Paper path
To resolve paper path problems, do the following:
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 Pinch wheels (using the Paper Load Handles) 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 Pinch wheels (using the Paper Load Handles) and pull the paper clear.
3. Replace the spindle if broken.
4. Perform the Paper Drive Test to obtain further information on the problem
Paper Drive test
on page 87.
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 87 and check that the values are
within the given limits.
2. Clean the Encoder Strip
See Clean the Encoder Strip on page 422.
3. Perform the Scan-Axis Test to obtain further information on the problem
Scan Axis test
on page 87.
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.
