Question about Panasonic KX-FB421 Plain Paper Film Fax
There are 2 thin vertical white lines on all printed pages from my Panasonic KX-FB421 Flat Bed Plain Paper Fax and Copier. They are on the left side of the page (1&1/8 inch and 2&1/8 inches from left edge of the page and each 1/16 inch wide) and in the same place always, regardless of whether I am making copies or receiving a fax. I have been told they are not on sent faxes received by others from me. I have cleaned the printing rollers and thermal head 3x with cloth and alcohol, (and cleaned the flat bed glass and white cover with a dry cloth). The machine is very clean and hasn't been used much (I'm using the 2nd replacement ink film roll). Thanks for any assistance you can give me.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Hi there check the machine scanner light by putting the original in the feeder and doing a copy. If the printout comes out OK then it either could be the other fax machine you are trying to send it to or you have a intermittent fault with your scanning lamp (Section).
You also must make sure that the original is text face down.
Hope this helps you

if you know how to disassemble the unit and know where LSU(LASER SCANNING UNIT) is located. try to clean all the mirrors you can find.
clean it with alcohol and clean rugs

Check the spongy black roller inside the machine for dust, wipe with a dry cloth.
Open your document feeder and check for dirt on the white bar.

make sure that "autoreduction" is set to on. should be in your owners manual. also, make sure your paper size is set correctly.
