"50 Error, or Service 50"

Error code 50 indicates that the fuser either (1) did not come up to the expected temperature in the expected time, or (2) came up to a temperature in excess of the expected temperature.

The fuser is a set of heated rollers which melt the toner into the paper. ERROR 50 or SERVICE 50 indicates that the fuser is either too hot or too cold.

Most HP LaserJets require 15 minutes, by the clock, to reset after declaring a 50. This is a safety feature, if the fuser was too hot, it should cool off before trying it again.

Frequently, a 50 comes up on cold mornings or after a long period of inactivity. This can simply mean it was slow getting up to temperature.

But you have to turn off the printer and WAIT 15 MINUTES before turning it on again. We have one old test printer which needs three cycles of turn off, wait 15 minutes, turn on again, before it will finally come to a ready.

If the message does not clear you have a repair issue. In some LaserJets this message means the fuser has ceased to work and needs to be replaced. In other LaserJets the problem could be either with the fuser or with the A/C power supply unit.

Fusers in most HP LaserJets are simple to replace. Many models do not require even a screwdriver.

We keep some fusers in stock. Quality rebuilt fusers are available from www.precisionroller.com. The price difference between an OEM fuser and a rebuilt is substantial, and a good rebuilt will last as long as an OEM.
