imageCLASS MF644Cdw: lines on scanned copies from the scanner top to bottom

[cjarn]

How can i get rid of this line from my scanner?  This only happens on the paper feed on top. If I scan a single copy on the table, there is  no line..

issue resolved by cjarn   after lifting the top of the scan tray, i looked on the top part of the scanner where it feeds the paper to the computer it was clear. but the other side onthe area directly under this had a couple small black lines on it.Ink or toner ?  that is what made the continious line possible. A q-tip with some alcohol took the black off.  now the scanner only sees the paper copy with no line.  result> clear copy with no line. problem solved!

I have this problem but am having a little trouble following the directions. I have the MF644CDW, which is a printer/scanner. I have looked at the spots I believe you are referring to, though I can not get past the plastic covering. I have blown pressurized air into the paper feed with no luck.

I have cleaned the roller, the platen glass, changed a cartridge that was 20% empty, and inspected all the cartridges for powder (none found), ran the maintenance (clean fixing assembly, ITB, and clean feeder).  None of these have resolved the black streak.  I particularly cleaned the metal roller to the right of the rubber feeders as I think that is what is making the marks as it lines up with where the streaks are on the paper.  All to no avail.  What to do now?
