There are lines appearing on my fax – how can I fix this?
The sending fax machine has a dirty scanner or scan strip
Explanation: (Modern) fax machines scan a document by moving it over a small scanner strip. If there is a small piece of dirt on the strip, it will appear as a large vertical (from top to bottom) line on the page.
Resolution: Clean the scanner or scan strip following the manufacturer’s instructions. Typically the scan strip is located near the start of where the paper enters the scanner. There may be one or more panels to open. With commercial grade equipment, it may be preferred to make a service call.
