line when copying

[PaulSt]

We have an hp color laserjet CM1312nfi MFP all-in-one printer up at work. When ever I copy something i get a line on the left side of the document. Any advice as to what the problem may be would be much appreciated.

Re: line when copying

I have had the problem many times with laser printers, usually helps to swap out the toner cartridge, however in printers that usually means more then just the container with the powder in it. In copiers the container with powder is sometimes separate from the drum and all the rest of the bits.

Had a copier once with the same issue, i think it started when someone decided to use overhead paper not made for copiers in it. Something got stuck somewhere and were lines there since.

What i think you have to do is swap the imaging drum. Dont know if its something separate or if its a big unit with most of the wear and tear parts in it.

I might have used the wrong terminology since im no pro repairman when it comes to these things :P

Define the problem more completely. Does it occur when printing, or only when copying (and presumably sending a fax)? How wide is it? If it's only when scanning, it's either something blocking the scanning sensor, or a dead sensor.

Clean the glass.

Re: line when copying

Does this only occur when copying?

What happens if you print a black and white text page without the copier is the line gone?

If so that rules out anything in the printing section of the unit the laser module, drum, and transfer roller aren't causing this.

This only leaves you will dust or dirt in the optical train of the copier or as Bill said a bad sensor or sensor control board issue.

Bad black cartridge/drum assembly. Using a remanufactured one? Don't. They don't replace the drum.

Re: line when copying

It is only when copying or scanning. It's a quarter of an inch thick. I can assure you the glass is clean. At first I thought it was an issue with calibration because the black strip covering the calibration strip on the glass has been worn down by someone using abrasive cleaners (white is showing in some areas of the strip). Looks like it's a sensor or something with the optical train. What can I do? Hopefully I do not have to order from the overpriced HP site. haha. thanks again!!
