Re: fax problem

Check the slit glass for white out or other foreign debris stuck to it and clean with isopropyl alchohol. Even a small dot or even dust can cause that. the led lamp array could also have some bad sections in it so it will not distribute the light evenly on the document to be scanned. If this doesn't help post a comment and I will research further and provide more solutions.

When I send a fax, the recipient gets all dark or black sheet. Thinking this was the recipients problem, I faxed again to a different fax number, same thing happened.

To fix the problem you have to check the scanner of your fax machine. It might not be functioning properly. Try to observe the fax machine while sending a document, look at the scanner section and see if the light of the scanner is turned on or lighted. If it's no longer lighted you have to replace it.

Hello, I have a little used 18 mth old Sharp FO P610 fax machine. It receives fine but when sending the recipient receives 'black all over' pages. I have tried disconnecting the unit for an hour and...

Try just making a copy and see if you have the black lines on your copy (most fax machines have a basic copy function if it is you have dirty scan glass and on these small machines it is a real hassle to get too and clean Try Canned Air. If no black line on your copy it may be the recipients machine.

Copies here and recipients faxes: dark, lined

How long has the drum been in there?
try this:
1-take out toner, look and see if it is ok. do you see stripes on it?
2- look at the drum are there any black rings on it? ( you did not specify white or black lines)
3- where the glass is on the opposite side ( the part you lifted to clean the glass, look at it standing from the back. you will see a white metal plate with some springs in it if you touch it. this is the reference that the fax has if there is/are a black dot on it it will give you a black line clean carefully. if it is scratched use white out to cover and make white again.

For the darkness try making a copy in photo mode if it is still too dark change drum.

Can't receive fax but can send

Call your cell phone from the fax machine and check the caller ID to make sure that it is the correct number for your fax machine. Next, call the fax machine from you cell phone, and make sure the fax machine rings. Problems like these are almost always a phone line issue, not the machine.
