I have an HP Neverstop laser 1000w that cannot pull paper, the machine was bought new, probably just printed 1 side of an A5 file. Now it has an error. It does not take paper. I checked and when printing, the Formater board does not supply power, it seems like the CPU does not control the signal to the Relay (24V coil) but there is no dead component. If you guys are experts, please advise me or introduce a shop that can handle it or fix it at home, that would be great. I bought a Formater board online but the shop sent me the wrong 1200w board, I tested it and it still does not take paper (it seems that the 1200w only adds the scanning function so printing still uses the same). I am not sure if the board I bought has the same error as my board.
