How to rotate
or replace HP LaserJet 4000 Series printer feed tires.
A common
complaint we hear from customers, especially those using textured letterhead
and bond papers, is that they experience frequent jam messages but cannot
find a jam in the printer. This is often accompanied by a groaning noise
as the printer tries to feed the paper from the tray. This problem is usually
caused by worn paper feed tires that cannot pull paper from the paper tray.
Users may find one sheet of paper pulled loose from the tabs in the paper
tray or they may not find anything out of place at all. On the HP 4000 Series
printers it is a fairly simple procedure to clean and rotate the tires thereby
saving the expense of a service call.

exhibits little or no remaining texture while a new tire (right) is heavily
textured.
Because the HP 4000
Series printers use two identical tires, for paper pick-up and double
feed prevention, users can clean and rotate them to extend their life.
One tire typically exhibits a great deal more wear than the other so if
they are rotated before one is worn out you should have them last until
they are replaced with the Maintenance Kit that should be installed every
200,000 prints. We generally recommend this procedure after about 100,000
pages if you find your tires are not lasting the full 200,000.
