The P4010 series printers were introduced in early 2008 and on the market until 2011. Replacement models introduced in 2011 were the LaserJet Enterprise 600 M601 ,M602 and M603, which look very similar but have changed formatter and motors. In spring 2015 the M604, M605 and M606 became the current model. They look rather different, but are similar to the M601 series inside.  The new models give a few improved features but the P4014 series are generally regarded as a good printer and well worth repairing.

Most of the parts are available in the catalog, if not email and ask.  


HP LJ P4014 and P4015 Internal Parts
HP LJ P4014 laser scannerLaser Scanners don't fail very often, and might sometimes be repaired as suggested here . Part number RM1-5465 can be substituted with RM1-7419. Error 51 involves the laser scanner.

Motors and paper pickup drive assemblies are not frequent sources of trouble either. The cog and spring have been known to fall off the end of the Z-shaft assembly - but aren't available as seperate spares.

The sensors can be tested in diagnostic mode.
HP LJ P4014 paper pickup and feed rollers
Paper pickup and feed rollers wear out over time and are quite frequently replaced, Frequent Error 13 problems (paper misfeeds) suggests one or more of the rollers need replacing. Rollers are avilable in kits.

Persistent double feeds and misfeeds despite changing the rollers and the torque limiter in the cassette are probably the solenoid. It will move if tested in diagnostics but given a diagnostics print run of ten or twenty pages the clicking will sometimes be mistimed.
