Preventing Media Misfeeds
Make sure that...
Media matches the printer specifications.
Media is flat, especially on the leading edge.
The printer is on a hard, flat, level surface.
You store media in a dry location away from moisture and humidity.
You always adjust the media guides in the tray after inserting the media (a guide that is not properly adjusted can cause
poor print quality, media misfeeds, and printer damage).
You load the media printing-side up in the tray (many manufacturers place an arrow on the end of the wrapper to indicate
the printing side).
Avoid...
Media that is folded, wrinkled, or excessively curled.
Double feeding (remove the media and fan the sheets—they may be sticking together).
Loading more than one type/size/weight of media in a tray at the same time.
Overfilling the trays.
AcuLaser C3900 Series     User’s Guide
Troubleshooting     115 
						

							Avoid...
Allowing the output tray to overfill (the output tray has a 200-sheet capacity—misfeeding may occur if you allow more than
200 sheets of media to accumulate at one time).
Clearing Media Misfeeds 
To avoid damage, always remove misfed media gently, without tearing it. Any piece of media left in the
printer, whether large or small, can obstruct the media path and cause further misfeeds. Do not reload
media that has misfed.
Note:
The image is not fixed on the media before the fusing process. If you touch the printed surface, the toner
may stick to your hands, so be careful not to touch the printed face when removing the misfed media.
Make sure not to spill any toner inside the printer.
c
Caution:
❏Unfused toner can dirty your hands, clothes, or anything else it gets on.
If you accidentally get toner on your clothes, lightly dust them off as best as you can. If some
toner remains on your clothes, use cool, not hot water, to rinse the toner off. If toner gets on
your skin, wash it off with cool water and a mild soap.
❏If you get toner in your eyes, wash it out immediately with cool water and consult a doctor.
If, after clearing the media misfeed, the misfeed message in the control panel window persists, open
and close the printer’s covers. This should clear the misfeed message.
