HP 4550 62 NO SYSTEM

[Brian27]

Color laserjet 4550 error "62 NO System". Replaced firmware, printer worked for 1 day then error came back again. Has anyone had this problem before. Manual says firmware is not present or is defective. Could this be a problem with the formatter?

THanks

It could very vell be a formatter board problem. What comes to my mind is that there is a problem with the formatter board that is damaging your firmware dimm. I would suggest replacing both the firmware and the formatter at the same time. If your formatter has damaged the firmware, it could damage a new formatter if it's brought over. I have seen it happen.

As a second issue, I have a question. Is the printer plugged into a surge protector? I have a customer that we've had to replace the firmware in his HP numerous times because it was on a surge protector. Laser Printers like to draw more power than a surge protector likes to let through, and sometimes this does damage the firmware.
