Hp HP LaserJet 4M

HP Laserjet 4m Postscrip

I am having two problems with my laserjet 4m (with postscript). The first is more urgent than the second.

Problem 1:

My printer is connected locally to a Win98 PC but is shared on the network by others. It arbitrarily stops printing. One day it is printing fine, the next it stops. When I send something to the printer, the ready light flashes once or twice, the form feed button lights up but nothing comes out. If I turn it offline and press the form feed button, I get a page with one line of garbage across the top to come out but that's it. This printer used to be attached to a Win95 PC and it started to have this problem, when it was moved to the Win98 PC it ran great for about 2 months and now this has started again. Does anyone know what is causing this or how to fix it?

Problem 2:

On the left side of my printer, the print is lighter than on the left side. There is a definite difference in the ink density from left to right. Does anyone know what I can do to fix this? It does it even with a brand new toner cartridge.

Thanks!!
I'm going to go under the assumption that the right side is lighter than the left side. This is because the airflow is from left to right. The dust tends to deposit on the right side of the optics. The laser bounce is weaker because the dust absorbs the beam. This results in lighter imaging on the photoconductive drum. Open the laser scanner and clean all the mirror surfaces with a dry q tip.

I agree with Moe on the second problem. As to the first, it appears someone in your office is sending jobs to the printer using the wrong driver. I would check each PC and make sure it has the correct driver. I would run a test copy from each machine to make sure. Most important are jobs sent by the PC which has the printer attached. Does that machine have more then 1 printer in its listing which goes to lpt1?

Thanks for your input moe and dmzcompute. Turns out I got the answer for the first problem from a different post on your site about hp iip's. I bought a new printer cable and everything's humming along nicely now. So the first problem is fixed. I haven't tried your solution to the second problem yet but I will. Thanks for your help.
