Troubleshooting stacker problems
The following stacker problems may occur during printing.
• Problem: Papers are being thrown around in the stacker.
This problem may occur when you have unloaded paper by
opening the top cover of the stacker bin.
NOTE: Do not open the top cover of the stacker bin to unload
paper.
To remedy this situation, unload the bin following the normal
procedure.
• Problem: The paper stack is falling over or sliding around in
the bin.
This problem may be due to excessive paper curl. Try the
following:
– Reduce the paper curl by adjusting the decurler. Refer to
the section, “Troubleshooting paper curl problems”.
– Reduce the number of sheets going to the bin.
Troubleshooting paper curl problems
Too much curl in the paper stock can cause paper jams.
Checking paper curl
You can adjust the decurler lever to correct most paper curl
problems. Refer to the paper curl chart, later in this chapter, to
determine the amount of curl in the paper stock.
Perform the following to measure paper curl:
1. Print five one sided (simplex) 8.5 by 11 inch or A4 sheets.
2. Hold the printed sheets by the top center of the short edge,
keeping the image toward you.
