Print quality Brother Intellifax 675 has 1 inch wide light gray vertical line when copying and on recipient's end. I have cleaned the scanner and plastic pressure bar with alcohol and lint free wipe. Line is still present. Any suggestions? Thank you, Ellen

IT WOULD BE A LASER RELATED ISSUE
TRY TO CLEAN THE LASER UNIT

It is NOT the drum. It is your document scanner. 2 inches wide is big so most likely it is not the typical scrap of paper or whiteout that gets stuck to the scanner glass. Lift up the ops panel where the documents are fed in to be copied. Look for a strip of glass that runs from one side to the other. Make sure there is nothing on the glass. At 2 inched wide it is more likely that you have some of the LED's that light up going bad. Under the glass is a row of LED's that light up to scan the document. If a block of these are not lighting up then this then causes the black band to show up. If this is the case then you will need to have the scanner repaired or buy a new machine which might be cheaper. No question tho, it is in the scanner as this is the only area that will cause clean incoming faxes but bad copies and outgoing faxes.
Good Luck and Thank You for using Fixya.

FIRST I would check the scanner glass again you can test it by asking for a report to be printed..ie tx REPORT.. if this dowsnt have a line on it the problem is either the scanner glass or at worst the scanner unit it self.. I would double check the glass.. get a soft cloth and some glass cleaner on it and give the glass a good rub over. do you have the lines on incoming faxes .. if not the glass or scanner unit is the def area to be looking at, Luck A

Open up the document feeder and clean the small glass. If the line is more than 1/4 inch wide you have a bad scanner block.

sounds like you are using generic drum and toner. try OEM (brother brand). you say copies are coming out completely gray. try printing an internal report from the control panel. if that is gray or received faxes are gray, then the problem is not in your scanner area, and i would wager you are using "generic" supplies.

Dust in the scanner, clean the scanner line inside the refill  compartment

1st print a report, can you see the lines? Then either the drum is faulty or the laser scanner is. If the lines are not present when printing a report, make a copy and see then if the lines appear. If so, the scanner is faulty. Try cleaning the glass with glass cleaner. However, blank lines mean that bits are missing from the scanner itself and the scanner will need to be replaced.

your machine most likely has toner spills in it.
if you send faxes face side down follow these instructions ;
1- take out toner
2- look for thin glass strip on bottom inside the machine
3-wipe clean

if you make copies side up then do the same except look for glass strip on the upper side of machine

This can be two things drum or toner more likely needs new drum, nothing to clean really except slidy blue tab on drum that slides up and down it cleans carona, fix for "vertical white lines"

If the problem only occurs when using the document feeder, the problem is not usually caused by the drum. When using the document feeder, try to notice where the scanner (the light assembly under your scan glass)stops just before the paper is being fed. Some multifunction machines have a small piece of glass that is separate from the large scan glass and the scanner assembly stays parked underneith it as the original is being fed over it. Most likely there is something on the glass where the scanner parks as originals are being fed thru the feeder. When putting your original on the large scan glass to copy, the mark on the glass will only show as a spot, but will show as a vertical line thru the whole copy when using the feeder.
