Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
I am researching that error - thank you for your patience meanwhile.
If you could mention whether there is any error light on the Laserjet, and whether you replaced anything in the Laserjet, or had a paper jam in it recently, that information might help.
That is a 'firmware error'... maybe.
There are several solutions suggested for that error.
First, press Cancel and then turn Off the printer.
Try turning it On again (without sending any print job to it) for about 15 minutes.
Meanwhile, go into the printer queue and remove and cancel all print jobs heading toward this printer.
Then see if the error is cleared.
Let me know how that goes, please.
