My UX-355XL fax was working well. Suddenly it is sending black copies to receiving phone. Also it does the same when I try to copy a page. What happened? I

Dear
Pl. make a copy on your fax machine, if its ok, then your fax machine is OK. else your scanner and related part may defective. However this may tested after SHADING ADJUST done on service mode.

Thanks.

The UX-300 is a fax/copier. It can send and receive faxes over a telephone line and it can make copies of paper documents. It is not designed to connect to a computer.
If you need a manual you may download a copy at

If everything is coming out Black it sounds like the lamp in the scanner has gone bad. If you can get the part from sharp it might not be hard to replace, but the cost may out weigh the cost of a replacement.

Noisy line? is all that strikes true when you ensure me it makes great photocopys, but then you receive OK, very strange, All the mechanisms for doing a local copy is the same as sending a fax the difference is the conversion to phone noise so it has to be electronic, I;d guess lightning/power surge, cant think of much else....sorry

I bet if you make a copy for yourself, the same thing is true.
The scanner bulb (or led array) is dead - meaning there is no light coming on when you scan your originals to send a fax or copy. You would normally be able to see the light(s) light up, if you peek under the auto sheet feeder as your originals are scanning, if not, then it is dead.

If you receive clear copies. Make a test copy. If it come out all black. Yes replace your fax . you have a bad scanner . cheaper to buy a new fax.

Nothing - your LED array (lights under the document feeder) is toast - you'll see the same result if you try to make a copy.

hello it sounds like you need to have the scannetr replaced

It sounds like your scanner is shot. Can you make a copy? Are journal prints OK?

What happens when you make a copy on your machine?
