Troubleshooting media problems
Paper problems can be difficult to detect. The following series of steps
will help isolate media-induced problems versus printer problems:
Isolate a paper path.
Isolate a brand of media.
Isolate a type of media.
Evaluate media-use practices.
Evaluate environmental conditions.
Here are some media usage tips:
Turn the media over and print on the other side. Doing so often
corrects excess paper curl.
Rotate the media 180° (end-for-end) to feed a different leading
edge. This can help correct multi-sheet feeding problems.
Media to avoid
carbonless media
media that has been preprinted (such as letterhead) with ink that will
not withstand fuser heat (175° to 230° C [347° to 446° F] for 0.1
second)
plastic-fiber media
embossed media
media with cutouts or perforations
chemically treated media
coated media
synthetic media
multipart forms
odd-sized media
If your printer is having trouble with jams, multi-feeds, or misfeeds, try
using HP 20 lb multi-purpose paper (part number 9300-2092) or
HP 24 lb LaserJet paper (part number 9300-2091).
