The BJ cartridge print head may have become too hot. If this happens, the
copier/fax may be slowing its printing speed at the end of each line to protect the
BJ cartridge print head.

■ The printout curls.

Your page may include a large amount of ink.
• Leave the page in the output tray for 30 to 60 seconds to allow the ink to dry. Then

remove the page being careful not to touch the document tray. Allow the page to dry
further, then roll it in the opposite direction of the curl. (Should you dirty the document
tray when removing the page, wipe it clean with a clean, soft, lint-free cloth moistened
with water or diluted dishwashing detergent solution.)

• The paper you are using may be too thin. Printing dense graphics on light paper stock

may cause the paper to curl. Try using heavier stock.
