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.

I have an HP6300 Officejet. When I fax something it is received dark and illegible and with lots of vertical dark lines


I need just a bit of clarification... you mention that when you fax, this means to another person, and is it thier printer/fax that gets the lines? Or when YOU get a fax in to your machine? If it is yours, we can tackle that, if it is the recipient, it is thiers..... Please let me know and we can tackle it! Guy :)

I have a Brother Fax 2850. When I send a fax the receiver has advised me that there is a vertical black line approx 2'' thick which blocks out some wording. How do I fix this?? Many Thanks Heather


Something is jammed in or covering the optics.
Check the area where the original document is placed for faxing.
Open this area and clean any liquid paper, sticky tape or staples covering the optics.
Test by making a copy. When the black line on a copy goes away the unit is fixed.
If the receiver is still getting this black line then it is probably their machine and not yours.
Send a fax to this number. 1300 368 999 It will send you back a copy of what it receives.

Two lines, one on each side of copies made from feeder and faxes


Try cleaning the rollers inside the scanner including the glass inside and out with a soft damped cloth. Look also for a piece of paper, staple wires, paper clips or pencil lead jammed inside the rollers or somewhere in the corner.
Also, look for a foreign object or substance on the cold cathode tube light and clean it. Try also cleaning the mirror.

Dark vertical lines


You have to clean the scanner.Open the dock feeder area,and make sure the scanner glass is clean sometimes the glass look clean but just a smaal dot on the glass can cause a line.Clean also the white area above the scanner.The white area above the scanner help for shading operation of the mchine.Make sure you clean with a sullotion that can remove ink but not damage plastic.

Transmitted pages are too dark, practically unreadable :


I suspect your scanner unit is going bad or it is extremely dirty.

Making a copy gets same result as when you send.

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.
