We have a Brother 4100 Fax Machine. When we send a fax or make a copy, there is a black bar about 2" wide that shows up the length of the page. It does not appear on incoming faxes. I believe it is...


Make sure the **** glass is clean, use a micro fiber cloth to wipe the debris/old toner or white out off the glass. restart the fax machine. If it prints this black line from a copy and it is 2" wide after you have cleaned both the glass and the white reference bar, most likley the scanner itself has failed.

Dark, vertical stripe on copy on Sharp AR-M160


Have you cleaned the small, narrow glass window leftmost of the platen? It is directly above the scanning bar's "home" position, and that's where the document is scanned, while it's fed by the feeder, passing over the bar (the paper moves, as oposed to platen scanning, when the bar is moving and document remains still).

When printing or faxing from the top tray of my HP OfficeJet 6310 all in one I get a line that runs down the entire page on the copy or fax to the recipient. I have tried cleaning the glass and rollers...


The key to solving this problem lies in what you observed. It only happens when you use the document feeder. As you noted, when you place it on the glass, there is no line.

When you use the feed, your machine does not pull the document onto the main glass to scan it with a moving bar. Instead, the bar parks itself under the roller section, and the document gets scanned as it rolls past the stationary bar. A spot or speck that blocks the light bar as the document rolls past manifests itself as a vertical line.

Lift up the left cover and the roller carriage and you will see a narrow pane of glass about 1-1/2" wide. This is what you clean. I cleaned mine twice, unsuccessfully, with a glass wipe. Then I decided to align the streak on my copy with the glass, and saw the faintest speck.You may have to look VERY VERY hard under a bright light, but it will be there. A third, more vigorous and direct scrub and the speck was gone--so was the streak.

If the vertical line appears in both modes (document-fed and manual) then there is something on the light bar, or the bar has a broken scan pixel. If the main glass were dirty, you would not see a line, but random spots, and then only when fed manually. Dirty feed rollers can make lines, but not usually the clean, precise lines that are created by a blocked scan bar.

Dark balck line down middle when copying, but not when printing


If this happens only when you feed the original through the top feeder and not when you lay it on the glass, then you have a small bit of dirt at the scanning location--since the paper moves, rather than the scanning bar, the section of glass that is involved is very small and one little bit of dirt will make a line down the whole page. You need to lift the automatic document feeder mechanism and clean the glass strip under it--that's where your (unseen) dirt is. (Page 108 of the manual, if you have one.)

Check the scanning glass bar. If you scanned something that had whiteout on it, a lot of times some of the whiteout will get on the glass and will cause streaks in the prints. Clean it with alcohol.
