What repair needs to be done for a "50 needs repair" message on an HP Laserjet IIIP?
ANSWER : I don’t know what you mean by good toner cartridges. They haven’t been built in about 10 years, so if they are new OEMs in the box, they are guaranteed to fail. The 50 error on that printer is mostly a burned out fuser lamp. This site was sold, so as you can see, there are no more kits available.

Toner cartridge full, printer displays: "empty needs replacing"
ANSWER : I once went to a customer who had a similar issue. They had installed new cartridges and judging from the box, they looked OEM. Strange thing was they felt empty when lifted and they were missing the chip on the outside that tells the printer it is installed and keeps track of how many copies were printed with that cartridge. The printer has no other way of knowing if the cartridge is full or empty.

Error message reads remove and check right cartridge
ANSWER : You can try cleaning the contacts on the back of the cartridge and the ones that they contact in the printer. Other than that, you have to replace the cartridge. I once had one that did the same thing. I swapped the cartridge with another printer of the same model and both printers worked fine. I swapped them back and the original printer got the same error. The other printer had no problem with either cartridge. I swapped them back and left them that way.
