I have an HP 4515 that is printing blank pages. I have tried to replace the toner and the power supply board. Neither resolved the issue. When the paper gets deliver out the paper is warm. This occurs when...
I believe I understand your issue:-
The printer is able to come to ready- your still able to navigate the menus. the printer goes through all the motions of printing except producing an image-
Having the machine print a test page ( internal Print ) tests whether the formatter is still able to generate a digital image ready for the print engine, but does not diagnose the print engine-
1) power down and remove power cord
2)remove the toner cartridge, use a pair of pliers and gently rotate the drum ( within the toner cartridge, a drive gear/mesh can be found on the end of the toner unit)- are you able to turn this drum or has it seized?
if it doesnt replace the new toner with another NEW toner and try again
3) return the power and power up the machine having first disconnected all network connections.
allow the machine to come to ready.
4) ask the printer for a config page ( internal print) and estimate when the paper is immediately below the drum surface ( toner cart) and using the power switch turn the printer off- causing a jam in the centre of the printer - this is ok we do this to see if an image has been generated on the drum surface- remove the toner cartridge and slide the drum protector plate to the side, look carefully at the drum suface ( you should see a latent image of a config page, at this point look at the paper still jammed inside the printer and see if there are any signs of toner ( there should be part of an image allready on the surface ) now if there is an image on the drum but no image on the paper then I would replace the transfer roller and or transfer HVT power unit, if however there is no image on the drum then you have a very serious problem which will require a new laser unit ( but this should really come up with a diagnostic error code)or Primary HVT unit.
