Open the front of the fax machine. Then pull down the the tray that has the down arrow imprinted on it. Locate the glass strip towards the back, just behind the center roller. Use a cloth and rubbing alcohol to clean the glass and that should remove the black line.

SOURCE: my machine is not printing

Mine did that when the drum was getting old and also when the inside of the scanner glass got dirty, Q-tip and alcohol fixed the scanner glass, Yours doesn't have a drum though it has a scanner window. so you just need to open it and find the window and do s little clean up. No more copies of dirty pictures for you though :-)

SOURCE: Is it poss. to disable the auto answering machine

There should be a button near the top left side area on the front of the printer that says "auto" and/or has a little red light next to it. When the light is on the printer will auto answer. Push the button until there is no light on and this should turn off auto answering.

There are a few models that do not have this button, but they still have the option on whether to automatically answer or not. It is just accessed a different way.

If you find you have a machine without an auto answer button and wish to turn this service on and/or off, press the "menu" key on your printers keyboard and use the arrows to scroll through the options available. When you the "basic fax setup" press the "enter" or "ok" key on the keyboard. Then continue using the arrow keys to scroll the options until you find the "auto answer" on or off feature and again press the "enter" or "ok" key to change it.

Some machines have two fax setup catagories. If you cannot find the auto answer key in this area, scroll with the arrow keys to find the second one and try there. I have found that some say "basic fax setup" and have another catagory on "advanced fax setup" ect.

Before I moved, my Lexmark all-in-one printer worked perfectly, but after I moved, everything worked EXCEPT printing of an incoming fax. Everything sounds the same through the sounds the telephone makes as...

Please go through the following checklist:
  • Make sure to plug the telephone fax line from the phone jack in the wall to the Line port on the back of your printer. For more info, please refer to the Lexmark X125 User's Guide.
  • If you have an answering machine connected to the same fax line, be sure to configure it so that it answers first before the fax machine (e.g. if your answering machine picks up on the 3rd ring, set your fax to pick up on the 6th ring or more)
  • If the line has a voicemail feature, disable it or request for a distinctive ring from your phone company.

How do I turn off protocol monitor on sharp fax model fo-235

Had exact same problem on UX 177. You need to clear the memory. On the UX 177 unplug machine, press and hold down the COPY button then press and hold down the STOP button. Keeping these two buttons pressed plug machine in. It should display message "clear memory ?" let go of the COPY and STOP buttons and press the START button. Will then display message "memory cleared". This will also wipe out all other programming but it is the only way to stop protocol report. Then reprogram all your settings.
That stopped protocol report printing after each fax. On some machines it may be the stop and start button the need to be held down on startup. It also seems to make a difference which button you push first even though machine is unplugged.
This problem returns after a power failure so if you have a lot of numbers programmed in you might want to get an inexpensive uninterruptible power supply or plug fax into UPS for computer if you have one.

The fax machine started printing paper out of no where. And doesn't stop. The "Sharp" name appears...then says "wait a moment" and starts printing blank pages.

The problem here is the protocol. The machine is trying to read a non existent remote fax. The firmware doesn't have a solution and there are no updates. Sorry, but if it's out of warranty, put it in a yard sale with a disclaimer.

Fax is received is very dark and almost unreadable

You can try using the menu to lighten the fax, but if all received faxes are dark, you may be experiencing a weak scan light. try making a copy instead of fax (which essentially is a fax printed to yourself) if also dark, its certainly your scanning imager that's failing. If that's the case I would recommend replacing the entire machine. Parts are expensive, and its a difficult to service part yourself. Also you may find that toner costs alone may pay for the replacement machine over this unit.

-Good Luck!
