Tips

If a paper jam frequently occurs in a specific place, carry out checks, repairs, or cleaning focusing on the jam

location.

A paper jam has occurred in the

paper tray.

Paper is not loaded in the correct

position in the paper tray.

Remove the jammed paper, then

correctly load paper into the pa-

per tray.

The number of sheets in the pa-

per tray exceeds the maximum

capacity.

Remove excessive sheets in the

paper tray, then re-load paper

into the paper tray.

The width of the paper guide has

not adjusted to the paper size.

Adjust the paper guide in the pa-

per tray to the paper size.

Bent or creased paper has been

loaded into the paper tray.

Remove the bent or creased pa-

per, then load new paper into the

paper tray.
