HP LaserJet M4555 cassette pickup, feed, and separation roller installation instructions

Installing the cassette feed and separation rollers.

Pull the cassette tray completely out of the printer.

Look inside the cavity for a cluster of rollers, see picture below.  You will be replacing 2 blue/grey rollers for each of the cassette trays.

Simply pinch the retaining tab inside the circular rim of each blue/grey roller, and slide the roller out towards you to remove it.  (NOTE: In the standard maintenance kit, the white/grey rollers will not be replaced because they wear less frequently.)

Push the new replacement rollers in place on the metal shafts.

Repeat this process for any other trays you have installed.
