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 flipper area during the flipping action.
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 flipper move freely.
7 Replace the flipper assembly as needed.

Jam in left
accessory
Recommended action:
NOTE: This jam should not occur during normal operation. The sensor in the paper path assembly might be
activated by media that jammed inside but is not easily seen.
1 Make sure that the sensor flag moves freely.
2 Verify that the optical sensor is not blocked.
3 Verify that the paper-path module has its sensor connected.
4 Replace the paper-path assembly as needed.

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 flipper area during the flipping action.

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 Check 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 flipper 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 flipper assembly as needed.

Jam in left
accessory
Recommended action:
1 Analyze the event log for 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 it arrives at the output device.
4 Verify that all of the sensor flags in the flipper and paper-path assemblies move freely.
5 Check for interference on the paper path.
6 Check for contamination of the paper-path rollers. Excessive paper dust can reduce friction. If excessive
dust is found, clean the rollers by using plain water and a clean cloth. If poor-quality media is suspected,
suggest that the customer use a better-quality media.
7 Replace the flipper assembly as needed.
