Pages are skewing

•Make sure the media loaded in the trays is aligned to the paper guides. If needed, pull out the trays from the device and reload the media properly, making sure that the paper guides are properly aligned.

•Make sure the rear access panel or optional duplexer is properly installed.

•Load media into the device only when it is not printing.

Multiple pages are being picked up

•Fan the media before loading.

•Make sure the paper guides are set to the correct markings in the tray for the media size you are loading. Also make sure the guides are snug, but not tight, against the stack.

•Make sure the tray is not overloaded with paper.

•When using thin special media, make sure that the tray is completely loaded. If you are using special media that is only available in small quantities, try placing the special media on top of other paper of the same size to help fill the tray. (Some media is picked up more easily if the tray is full.)

•If you are using thick special media (such as brochure paper), load media so that the tray is between 1/4 and 3/4 full. If necessary, place the media on top

of other paper of the same size so that the stack height is within this range.

•When reinserting Tray 2 (optional) into the device, do so gently. Forceful insertion with a full stack of paper may cause sheets to slide up within the device, causing the device to jam or pick multiple sheets at one time.

•Use HP media for optimum performance and efficiency.
