The control-panel messages indicate the current product status or situations that might require action.
Control-panel messages appear temporarily and might require that you acknowledge the message by
pressing  OK to resume printing or by pressing  X to cancel the job. With certain messages, the job might
not finish printing or the print quality might be affected. If the message is related to printing and the auto-
continue feature is on, the product will try to re sume printing after the message has appeared for 10
seconds without acknowledgment.
For some messages, restarting the product might fix th e problem. If a critical error persists, the product

Jam in cartridge area Photosensors PS913 (media
width sensor), PS912 (top of
page sensor) and PS915 (fusing
assembly exit sensor) detect
paper in the cartridge area of the
product. See 
Figure 7-7
Components in the print cartridgecavity on page 199 and Figure
7-6 Components on the rear sideof the product on page 198. If
paper arrives at these sensors
too early, leaves the sensors too
late, or is present at the sensor
when not expected, an error
message is displayed.
1. Make sure that the paper
meets specifications. See
Specifications
on page 291. See Commoncauses of jams
on page 229.
2. Open the top cover and
remove the print cartridge.
Remove any paper or paper
fragments present.
3. Lift the registration flap.

on the engine controller
PCA are seated.
Jam in output bin   This error occurs if the duplex
reverse photosensor (PS918) or
fusing exit sensor (PS915) detect
unexpected paper.1.
Make sure that the paper
meets specifications. See
Supported paper and print
media on page 32.
2. Open the rear duplex jam-
release door and clear any
visible paper. Verify the
duplex-release sensor flag
moves freely. You might
need a pen light to observe
the flags.
3. Open the face-up output
door and the verify the exit
sensor flag in the fusing
assembly moves freely. You
might need a pen light to
observe the flag.
4. Verify that the following
connectors are seated on
