Recommended action:
1 Print and analyze the event log to find out whether the error occurs repeatedly.
2 Make sure that media is not being pulled from the accumulator area during registration.
NOTE: Customers who copy a single-sheet document might grab the copy from the device while it is flipping,
not realizing that the action creates a jam condition.
3 If the jam occurs when using heavy or glossy media, run a test using plain, 75-g/m
4 Make sure that the correct paper size in the trays is selected according the paper size being fed.
5 If possible, install the failing output device to a different printer or MFP and test it on the other printer or MFP.
6 Make sure that all of the sensors in the accumulator move freely.
7 Make sure that the firmware for the device is at least 030213. If it is not, then upgrade the firmware.
8 Replace the accumulator assembly as needed.

Jam in left
accessory
Recommended action:
NOTE: Customers can create this jam by blocking the accumulator exit. A customer might attempt to pull media
from the face-down bin, not allowing the media to complete its path to the face-down bin.
1 Make sure that no media exists on the eject area that might prevent a new page from being delivered.
2 Make sure that the stacker bin is not overloaded.
3 Make sure that the stopper clips are installed correctly
NOTE: Sometimes, when the accumulator module is replaced, the stoppers are not reinstalled in the correct
position.
4 Print and analyze the event log to find out whether the error occurs repeatedly.
5 Make sure that the firmware for the device is at least 030213. If it is not, then upgrade the firmware.

Jam in left
accessory
Recommended action:
1 Analyze the event log for the frequency of the error message.
2 Make sure that the media is well-aligned in the input trays.
3 Make sure that the media is not wrinkled before arriving to the output device.
4 Make sure that the media is coming out in the accumulator well-centered. If this is not the case, then check
the input trays to make sure that the media is centered and not closer to either front or back.
5 Make sure that the media is not touching the plastic arms (wings) in the accumulator.
6 Make sure that customers are not blocking the exit of the accumulator when waiting for their print jobs.
7 Check for interference at the exit of the accumulator.
NOTE: Paper that has excessive curl can block the exit.
8 Make sure that the paper-stopper clips are in their correct position.
9 Make sure that the accumulator exit roller cover is installed correctly.
10 Replace the accumulator as needed.
