Things to Check if the Top Corner of Printed Pages are Folded Over

The Fuser Guide Assembly can get caked on either side with excess toner. A telltale sign is a top corner of the printed pages being folded over. Many times you can remove the fuser, knock off the baked on toner pile with a small flat blade screw driver and the problem is solved. Look at the entire guide while the fuser is out and take off any other toner piles you might find along the other ridges.

This guide may also become warped, so check to make sure it’s installed correctly and that it’s straight. Look for a rise in the middle as this can cause accordion type jams in the fuser. And if any print jobs include stickers/labels, a warped guide condition makes it easier for the sticker to come off the backing paper and stick to the heat roller making a real mess.

The Fuser Guide Assembly is easy to replace without dismantling the entire fuser, if you’re careful. Prior to removal, make sure you have the right guide as a replacement (99A0713 for the Lexmark S series and 99A1591 for the Lexmark T Series). There are different styles and part numbers, so be sure you have the correct part before proceeding. If you’re not certain, remove the warped guide to compare the shape and mounting prong locations.

To remove, lift up in the middle and one side or the other and it will come loose of the mounting holes in the frame. If it doesn’t break, slide that side along the frame toward the front of the fuser. The other side will follow.  To install a new guide, simply place one end in the mounting holes and lift up gently to slide it into place.
