Power off and on ater every use

    My Laserjet 3330 makes the same "racheting" sound, and I used to be able to solve it by powering on and off, but now the problem is constant, and I can no longer print, copy or scan. I re-downloaded the driver software from the HP site, which fixed it for a day (unless it did nothing, and the apparent fix was only a coincidence), but now it is back to working not at all. Is it indeed a terminal scanner problem?

Take the small piece of glass off the scanner and use a hacksaw blade or wire or something like it to push the scanner bar as far back as you can. cycling the printer many times can sometimes get the scanner bar into the right position and then it will work normal.

You have a bad scanner. It will cost as much as a new machine to replace it.

I have a HP laserjet 3330 and I dont see a off button. How do I turn it off.

Interesting question.
Checking the service manual it appears that there is a power switch only on the 220v printer!!!
I guess you have to pull the plug.

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...

The scanner is either worn out or just dirty. If you can remove the top glass you can gently wipe the mirrors and lenses with a Q-tip and clean the white strip on the underside of the glass. If that doesn't help the lamp is just worn out not putting out enough light. Parts are not available for that so it could be time for a new machine.
