							Preventing Media Misfeeds 215
Preventing Media Misfeeds
Make sure that...
Media matches the machine specifications.
Media is flat, especially on the leading edge.
The machine is on a hard, flat, level surface.
You store media in a dry location away from moisture and humidity.
You remove transparencies from the output tray immediately after printing to 
avoid static buildup.
You always adjust the media guides in Tray 2/3 after inserting the media (a 
guide that is not properly adjusted can cause poor print quality, media mis-
feeds, and machine 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). 
Fanning transparencies since this causes static.
Loading more than one type/size/weight of media in a tray at the same time.
Overfilling the trays. 
Allowing the output tray to overfill (the output tray has a 250 sheet capac-
ity—misfeeding may occur if you allow more than 250 sheets of media to 
accumulate at one time).
Allowing the output tray to fill with more than a few transparencies.

13. Output tray
Clearing Media Misfeeds 
To avoid damage, always remove misfed media gently, without tearing it. Any 
piece of media left in the machine, 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 machine.

							Clearing Media Misfeeds 217
CAUTION
Unfused toner can mess 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.
CAUTION
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 message 
window persists, open and close the engine cover. This should clear the mis-
feed message.
