Recently our fax machine has started scanning and sending documents with heavy lined marks down the left hand side of the page. I have cleaned out the whole scanning area, that I can reach, and still the same problem. I presumed that it was just dirt that I could not reach, but here's the catch: It does not print/scan/send this mark all the time I just managed to do a copy on the machine with marks, then straight after did a copy with no marks? Can someone please explain to me how this makes sense!
First print a report to see if the lines appear without using the scanner. If this is the case clean the charge wire. If you pin it down to the scanner, it is probably a poor solder joint on the cis unit. Take it out and run a hot soldering iron over all the joints on the reverse side of the cis.
