I get a solid 1/2 inch black line on the left side of the page.

TCON failure

This type of line is cause by a scratch or smudge on the toner cartridge's image drum. You will need to replace the toner cartridge.

You have an "Up Scaling" problem and a new screen will sort that out.

It could be 2 things...

1. Your scanner glass is dirty...open the doc feeder and clean the glass. probably Wite-Out.

2. A segment of your scanner assembly lamp is burned out. Not good, uneconomical to repair.

Is it From top to bottom? if it is, clean the optics unit, its lens array and mirrors.

i'm not sure if you're talking about a solid black band or a bunch of little stripes running down page. does it happen when you run an internal report or only on copies? if its a black solid band, check and make sure the bluish colored tab on top of the drum is all the way to the left side. if its a group of fine lines, depending on whether it happens on internal reports or not, it could be the drum is going bad or you may have a bad scanner. write back with a little more info if this suggestion doesn't work.

good luck,

toner cartridge is leaking, change to a new toner, and clean the pickup rollers.

can you try to post a copy of what you see wrong . and try to do an internal printout " function-6-4-start- under the fax button. "

Shake the toner cartridge left to right, then try.

Sounds like the fuser.
stop the printing before it comes out of
the exit rollers by powering it off.
If half your page is good its the fuser.
