HP Laserjet 1200 - small vertical white line

I just started getting a small white vertical white line that appears about 3 inches from the right side of the page. I've removed the cartridge and looked for anything that may be causing the blockage but couldn't see anything.

Any ideas?
White lines can be caused by a couple of things. Dust on the laser scanner optics or anything between the laser and the drum in the cartridge will block the beam and cause a white line. Could also be something caught up under the toner roller in the cartridge, causing a void of toner and resulting in a white line. That line would be fuzzy. The other would be sharp and defined.

I would try a new toner cartridge before attempting the scanner though its not hard to get too.

You will have to take off the top cover.

The back and side covers need to be removed too.

Here's the order:





The laser/scanner is the black box you see when you take the top off.

Use a dry cotton swab to clean the optics, liquid can cause streaks, which are a bad thing.

Keep fingers off of the inside parts of the scanner.

Never lube a scanner motor unless it's really bad, the oil tends to get flung all over the insides of the assembly.
