hp 1320 prints only white pages

[groovy]

Hi all,
here lies an old-but-still-good hp 1320.
Changed main power board, laser and formatter, now it is still printing only white pages.
The laser lock mechanism looks good.
Any ideas?
Thanks

Have you tried a stop test to see if the drum forms an image?

I would also take a good look at all the black pieces that guide the cartridge into place. You might not be getting a good ground somewhere, or something of that nature.

Sorry for my question but have you tried to replace the cartridge?

Take out PCR Roller and do a test,you should have black page.

Cartridges are ok (tested other 2 cartridges that works on another printer)
Now i look at the cartridge HV contacts and the transfer roller.
Thank you so much.
