HP 4L all LED up

[Strat]

This Hp laser printer 4L works good. Now it suddenly quit the printing job and all the LED lit up. Unplug the power and plug it back in. It will work for a while then it will do the same things over again. I checked the roller- it\'s fine.

What are the problems? Not on fuse unit, is it?

Thanks for all the ideas.

Alot of printers had a readout on the printer but this printer doesn't. The printer display is on your PC minotor. I have attached a page in PDF format. When you open the file (4trouble.pdf), read and follow the procedures. Remember and post it here. This will get you closer to the problem. I will try and help you. Hope we can find out what the problems is.
