Large Black streak on outbound fax/copy

There is a large black streak down the side of all of our outbound faxes, and any copies we make using the fax machine.
I have cleaned the scan unit - also disassembled and reassembled, making sure that all connections are secure. the problem persists
the line does not show on inbound faxes. My guess is that the scan unit is defective.

I have an hp LaserJet 3015 PCL-6 all in one printer, copier & fax. When I use the copy function, there is a black streak running down the length of the copied paper. I tried replacing the toner...


Clean the thin glass strip that sits to the left of the flat bed glass.

That is the glass used when the ADF is being utilized.
There is dirt on it causing the black streak.

My brother MFC 8500 is receiving alright but everything I send out has a big black streak going down the right side of the page. Confirmation page also has big black streak.


Let me see if I got this right.

The received fax is clean but when you send one out it has a black streak on it.
Cool! So far so good.
Makes sense because for sending, the fax scans the original document and parts of the scanning area could be dirty and so on. Therefore a black streak may appear.
The same black streak would also appear when you make a copy, because the original document must also be scanned.
Logical!

However for receiving faxes, the machine uses the internal memory and the print engine only, and the same applies to printing the transaction report, which comes from inside via the print engine.
The scanner has no rol in either situation.

Now I'm lost!

Yes, you have a burned out scanner block element. It's cheaper to buy a new fax machine

THERE ARE LARGE STREAKS OF INK ON ALL COPIES AND


The green roller is the drum which has a cleaning blade to remove excess toner, when the drum gets older it becomes clogged and will dump toner back out onto the drum. Just some info on it. Best fix is replace the drum, you could take it apart and attempt to dump and clean it but it's rarely worth doing that.

I have a black streak all on one side when i copy ?


If it is just when you copy and not when you print then it is a cleaning issue. Toner cartridge would cause the line to appear on copies, printouts and faxes. There is a piece of glass inside the auto document feeder that is probably dirty. Open up the document feeder as if you were clearing an original document jam. Look for a piece of glass inside the ADF, it will run the length of the document feeder. There is probably some dirt or another popular problem is white out. Clean off the glass with glass cleaner or alcohol and it should fix the problem.

Getting big black streaks though copies


OK I am guessing this is a Laser Fax or an Inkjet Fax- If it's a Laser Fax,chances are you may have a "BAD" drum and if this is a Ink jet most likely and "Leaky" cartridge.

Black vertical streaks on faxes & copies


On top of the toner/drum cartridge there should be a blue slider, move back and forth 10 times.

If no fix, you need a new toner cartridge.

Dirty copies.


Does this streaking problem occur when printing (not copying)? If it does then you are probably looking at a consumable issue. Alot of times black streaking is caused by a defective or spent drum. Is your drum new? There is also a blue piece on the drum unit used to clean the corona wire that cleans the drum. Have you tried moving it back and forth several times?

If the problem only happens when copying and the streaks are as bad as you make them out to be then you problem have a bad CIS unit (scans your originals for faxing or copying)

Blank Streaks


streaks are caused either by the toner, drum, lamp or fuser.

If you make a copy and it does not show a streak then it was done by the person sending the fax. BUT, check this,

open door and take out toner cartridge. look for a thin glass that is on the bottom of the machine and wipe it. Toner spills will cause a black streak.
