Document scanning with lines

Probably there is nothing wrong with that scanner, just open and clean document feder with alcohol or glass cleaner.

• Check the connection. The cord from the TEL.LINE jack to the wall jack should be no longer than
six feet.
• Make sure there are no modem devices sharing the same telephone line.
• Check with the other party to make sure their fax machine is functioning properly.
• Have your telephone line checked for line noise.
• Try connecting the fax machine to a different telephone line.
• If the problem still occurs, your fax machine may need service.
Clearing a jammed document
If the original document doesn't feed properly during transmission or copying,
or DOCUMENT JAMMED appears in the display, first try pressing start/memory . If
the document doesn't feed out, remove it as explained below.
Important:
Do not try to remove a jammed document without releasing it as explained
below. This may damage the feeder mechanism.

download reginout cleaner and do deep scan with it, it will fix it

Clean the scanner strip glass. This is the thinner strip of glass that runs from front to back right next to the large glass. This glass is only used when scanning/copying using the document feeder. The line you are seeing is because something has become stuck to the glass so when the documents are fed over the strip of glass, the scanner reads the stationary spot of debris as a solid line. Clean the glass very well using a cloth and some glass cleaner. I have seen something get under the glass as well but this is very rare. Rest assured tho that the line is being caused by something on this strip of glass.
Good Luck and Thank You for using Fixya.

When you use the adf, the scanner remains stationary at the far left side of the platen. Check and make sure that the glass is very clean there; use a damp cloth to remove any dirt or other foreign material.

there is probably a dirt spot on the scanner glass where the document feeds in. try cleaning the thin glass under the document feed cover.

If you are scanning using the Auto Document Feeder be sure to clean the glass where the documents get scanned. A small speck will cause a line down the page. On HP there is often a narrow strip of glass on the left side of the platen glass.

try cleaning the glass scan bar on the unit with a clean soft cloth.
