HP Color LaserJet 4550 DN error 54.2

-if you power on the printer, it goes into error 54.2 rightaway

-you can only remove or insert toners manually, the printer menu, buttons and display do not work (give error 54.2 after poweron)

-if you release the brake, you can trun the caroussel in both directions all the way around, there are no obstructions. ??? can you really rotate the caroussel more than 360 degrees???

-the caroussel can rotate freely with and without toners installed?


My guess (but i am not a printer pro...) is there is an issue with the caroussel sensors, clean them with a brush. these sensors can get very dusty.

Other problem: maybe fawlty caroussel drive. Did you watch the printers movements during power up? Is the caroussel actually truning?
