A 52 error is a Scanner failure. Do you hear a "whirring" sound when you get the error?

That's the sound of the scanner motor running amuck.

You're probably going to have to replace the Laser/Scanner assembly or the DC Controller which controls the Laser/scanner motor.

1. Reseat the cartridge. Try a new or know good cartridge. If OK, stop.

2. Check the Hi Volt contacts on the cartridge for damage. If the contacts are dirty or damaged, clean the contacts after the repair.(This is especially important if the cartridge is recycled.) If OK, stop.

Before going further, evaluate the cost effectiveness.

3. Replace the Hi Volt Power Supply. If OK, stop.

4. Check and reseat the HVPS cable

No Toner then it prints again..
This could be lower toner, a generic toner cartridge will sometimes produce this, or dirty contacts where the cartridge lays in machine.
Look at the toner cartridge, where you see shiny silver or bronze, clean excess toner off, also in machine where toner cartridge lays, clean all excess toner out.

usually its a defective toner cart. recycled carts are just refilled, they are not reconditioned. I would remove that cart, clean the mechanism, and replace with a new cart.
