I have an hp laserjet 3330 copy/fax machine and it keeps saying power off, power on, power off, power on...It doesn't seem to have a power switch but I've unplugged it and plugged in back in but the scanner error message will not go away. Suggestions?

Optical scanner assembly faulty, its avil replace it if not open the unit gently remove the cover clean reflecting mirroes with ears buds to aviod scratches, refix and try.. best of luck

Hi, first of all you have to be sure that you are plugging the cables in correct places. Then please press the "on hook" dial button and if you dont hear any signal then maybe your HP has damaged fax option. Also there is a difference between "pulse" and "tone" line signal. Please check that option in the fax menu.

suspect either worn ADF(automatic document feeder) pickup roller or there is a jam in the ADF unit where the paper feeds to the scanner.

The problem may be in the machine you're sending to, if you get a copy thru the adf or on the glass with no lines, it's the same image you would send thru fax. Check the narrow glass though, I usually find white out on that glass and have to clean it off.

it is the online printer it have no on off switch off is very essaincial use a power stafe

I have that oranage triangle light blinking as warm up message continues I also had power loss I have taken the plug out and will wait a while and try again. I still get now scanner errors using ubuntu..

PDF files are notoriously slow to print. You might invest in more printer memory.
