The old Canon SX printer engine was used in lots of printers and this tray should be compatible with any of the printers which used the old Canon SX engine, but this one has HP part numbers: RS1-8589 & RS1-8355.
This tray is in pretty good shape for being decades old - it has some yellowing of the plastic and some scratches - LOOK AT THE PICTURES!
