Table 7-8. General Paper Path Troubleshooting Questions (continued)

Troubleshooting Check

Action

Are the paper tray guides set correctly?

Ensure that the left-side paper guides for Trays 2 and 3 are set correctly at both the front and rear of the trays, and that the front guide is locked into the correct position. For Tray 4 ensure that all adjustments are set correctly: front, back, and side, at the top and bottom of the tray.

Does the printer need to be cleaned?

When was maintenance last performed on the printer?

Inspect the paper path and paper path rollers. See the cleaning procedures in Chapter 4.

Determine from the Configuration Page the number of pages since the last maintenance (see Figure 7-7 on page 7-52). The Printer Maintenance Kit should be installed every 200,000 images.

There are four photosensors (PS102, PS103, PS106, PS501) in the paper path for detecting arrival or passing of the paper.

If the paper does not reach or pass these sensors within the prescribed time, the microprocessor on the Engine Controller Board assesses a paper jam and notifies the Formatter of the jam. See page 7-92 for the location and function of sensors.
