The LJP4010 series printers were introduced in early 2008 and on the market until 2011. The replacement models are the LaserJet Enterprise 600 M601 ,M602 and M603.

Most of the parts are available in the catalog. However other than the rollers and the complete assembly there aren't many HP original parts for tray-1 -there may be "refurbs".

If you have changed the rollers the remaining faults with tray-1 are likely to be the solenoid.
