WHATR IS hp 3600 error 59.60 - HP LaserJet 3600n Printer

SOURCE: hp colour laserjet 5550dn comes with error 59,60 what could be the problem

That error indicates that there is a problem with the cartridge rotation motor. This is not something you can repair yourself. You can check and make sure your toners are fully inserted and that the carriage is not jammed, also check the transfer belt and make sure it is installed correctly. Other than that this will involve disassembly of the printer.
