Initial Actions for Jam Errors
Some initial steps to take when evaluating repeated jams:
1. Clear the paper path of any jams and paper debris.
2. Make every attempt to establish a jam rate prior to starting any work. If 
possible print an Error History Report and note the page count between jams.
3. Determine if jamming is occurring in one tray but not another. This helps to 
identify any dirty or defective parts.
4. Clean the Feed and Retard Rollers in the paper tray and tray slot using a 
slightly damp (water only) lint free cloth.
5. Ask the customer about the paper types being used. If not on the 
recommended list, determine if this is contributing to the problem. See “Media 
and Tray Specifications” on page 1-15. 
Recycled, multi-purpose or copier paper tends to contaminate the paper path. 
Constant use of special papers such as labels or business cards can also 
contribute to jamming.
6. Ensure the correct tray loading and setup procedures are followed (securing 
the guides, selecting the correct paper type, fanning the paper, etc.)
7. Make sure the printer is plugged directly into an electrical outlet. Using 
extension cords or a power strip is not recommended.
8. Verify that the printer is operating within standard environmental 
specifications:
• The temperature is 10 to 35° C (50 to 95° F).
• Relative humidity is 10 to 85%.
If the printer is operating in an environment that is outside of these 
conditions, jam errors can occur more frequently. You can move the printer to 
another location, or correct the environment that the printer operates in.
9. Cycle printer power, and if the problem persists, follow the troubleshooting 
procedure.
