Troubleshooting

Check the calibration values of the drive roller calibration, refer to the service plot How to Interpret the 

Service Plot’  page 251.

Perform the following check: 

1.

Lift up the PPS in loading position, 

2.

Remove the rubber cover drive roller encoder disc

3.

Check that the drive roller motor and motor mount is correctly installed. 

4.

By rotating the motor coupling by hand, check that the retainer plate (shown by the lower red line in 

the picture above) is well positioned and tight.

5.

Check that there is a least one tab bent, as shown in this picture below.

6.

If there is no bent tab, try to tighten the driver roller, if it does not turn, do not force it too much, this 

would indicate the part is tightened sufficiently.
