Re: drum? glass? on faxphone?

I think this fax phone uses ink. there is possible dirt on Contact sensor glass. you can use a damp in iso cotton bud or cloth to clean it.

When I fax the recieptent is getting 2 big black lines..........ive tried cleaniung it but not sure if im cleaning the corredt parts..........there a little glass part that looks like there may be ink

Open the auto sheet feeder (where you place your originals), look underneath and you will see a narrow "scanner" glass that the originals are scanned across. Clean this thoroughly with glass cleaner (or water) - there is probably correction fluid or some other foreign dirt on it. If you make a copy for yourself (before and after) it gives a good indication of the quality you are sending to fax recipients.

good luck, and please rate solution

Don't know that machine all that well, but it sounds like the laser filter glass may be dirty, or the laser unit. It seldom happens, but did you by any chance blow it out with compressed air?
Anyway, you may try taking out the toner cartridge, and if you tilt the machine upward you should see a sort of 'filter glass" above where the cartridge sits that allows the laser light to pass through from above. try cleaning this with a cloth, and hopefully that will solve your problem.

Black marks only when faxing

check the Scan glass where you put the original to fax, there should be a door to open and see a small strip of glass, clean it.

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.
