Re: 775 fax machine

This is most commonly caused by Tip-ex on the scanning glass. lift the lid to the scanning unit and clean it off with a damp cloth, prefferably an alcohol solution. Hope this helps Cops

Change toner

Step 1 Check the top of your Canon fax/copy machine to see if your specific model has a protruding extension piece from the plastic delivery tray. Push the extension piece down if one is present on your model.
Step 2
Grip the bottom edge of the paper delivery tray at the front of the machine. Lift the tray upward to reveal the rectangular, plastic toner cartridge inside the machine.

Step 3
Grab the handle at the top of the current toner cartridge and lift the cartridge upward. Pull the toner out of the machine and set it aside.
Step 4
Set your replacement toner cartridge over the empty space in the fax/copy machine. Ensure that the arrow near the bottom of the cartridge is facing down, and line up the protruding guide piece on the left side of the cartridge with the groove inside the machine. Push the toner downward until it snaps into position.
Step 5
Push the paper delivery tray back down, and lift up the extension piece if your model uses one.

I have a muratec F320 fax machine. When we photo copy or fax something it is coming through with a line on the left hand side of the pg all the way from top to bottom

Open the lid of the ADF and check the **** of glass that runs from back to front on top of the machine, most likely corrector fluid or some kind of foreign matter on the glass.

Unwanted verticle line on fax copies

Most likely a fax has been sent or a page copied with 'white out' (Liquid Paper), still wet on the page. As the page feeds over the scanner, (a narrow strip of glass that runs across the width of the page along the feed path) the wet liquid paper comes off on the glass as a thin line and dries. Thereafter, when copying, scanning or sending a fax, the scanner light does not go through the liquid paper streak and the result when printed is a thin vertical line that runs the full length of the page. If this is the cause you will also find that faxes you send to other people will also have this line (although faxes you receive are not affected by this problem with your machine).

To fix the problem: follow the path that the paper travels when sending a fax or making a copy, until you find the scanner (narrow glass strip). Take a clean, soft cloth and a small amount of methylated spirit (or white spirit) and remove the now dried Liquid Paper from the glass. Clean the whole strip ensuring that the glass is left clean and dry.

How to send a fax

  1. Plug the phone line into the jack marked LINE.
  2. Insert the document top-first, with the printed side away from you, into the top slot right behind the operator panel.
  3. Enter the phone number, just as you would to dial any phone. If it's long distance, include 1 and the area code. If you're in an office where you need to dial 9 first, do that.
  4. Press Start.
The fax will do everything else.

My brother 775 fax machine when makin a copy of something on it, it leaves a black strip right down the middle of the page what causes this?

either the exposure glass is dirty of it has a dead spot on the exposure lamp assembly, open the area the originals are fed through, you should see a long narrow peice of glass, if this has a spot or streak on it it will transfer that to everything that passes through. Clean the glass throughly with a good quality glass cleaner and a soft paper towel. then try again.

Hope this is of some help.

Black line about 1 1/2 inches wide down side of faxes or copies

if your RECEIVED faxes look good, then leroyal is dead on. you will need a new CIS which stands for contact image sensor. if you have an authorized brother service center nearby, they may be able to do it for 100 to 150.00, depending on their pricing of course. if rec'd faxes are bad also, pull drum out and make sure the blue tab on top of drum is all the way to the right side, although that usually only leaves about a 1/2" black band.
