Jam Error Procedures
For jam errors, perform these basic steps before you begin the troubleshooting
procedure to rule out factors not related to mechanical function.
1. Ask the customer about the paper types being used. If not on the recommended
list, determine if this is contributing to the problem. 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.
2. Ensure the correct tray loading and setup procedures are followed (securing the
guides, selecting the correct paper type, fanning the paper, etc.).
3. Make every attempt to establish a jam rate prior to starting any work. If possible
print a Status page or Usage Profile report and note the page count between jams.
4. Determine if jamming is occurring in one tray but not another. This helps to
identify any dirty or defective parts.
5. Clear the paper path of any jams or paper debris.
6. Clean the Feed and Pick Rollers using a slightly damp (water only) lint free cloth.
7. Cycle printer power and retest.
If after following these steps, the printer continues to jam, go to the troubleshooting
procedure indicated by the error.

Media reached Feed-Out Sensor #1, but did not arrive at the Registration Sensor #1 or
Transfer Unit Entrance Sensor on time. This error represents a misfeed jam for media
fed from Tray 1 (MPT).
