Re: black streaks on paper when printing message

Either your waste toner is full or more likely the drum cleaning blade is knackered best to replace both blade and drum

That green bar is the drum unit. Black streaks are indication of bad drum. Replace drum unit. Don't wait too long or it will ruin the fusing section as well from excess toner build-up. Big bucks!

I'm noticing black streaks in my copies, how do i clean it?

Open the feeder from the top of the will see a thin strip of glass maybe 1/2" wide running from the rear of the machine to the front..odds are there is glue/dirt/corrector fluid or some other dirt on the glass. Clean this off.

Brother hl-3045 jam inside

Had the same problem, called help center and fixed it!!!
Problem occurred when i tried to print colour labels from Word.
Black cartridge printing worked fine.
When using manual feed (pull down black panel in front which says 'brother'- you'll get the message for this if printing labels
you must open the back door of the printer.
got 'paper jam inside' error message.

Here's what I did and somewhere along the way, something worked.

Turn and unplug machine
take out all drum cartridges (all 4)
Take out the black belt (everything you can remove has a green arrow or tab- easy)
check to see if there's any paper in there- there was no paper in my case.
separate the drum from the cartridge for each colour and check the colour roller and the fuser film roller- don't touch them- no paper stuck that i could see
put them back together carefully.
Put the belt in and then the 4 cartridges
do a test run- mine still showed error message- paper jam inside
switch black with each cartridge and do a test run for each. When i switched with yellow - didn't work, magenta- didn't work- cyan- WORKED!!!- the colours were messed up on the document but it went through and printed without the error message.
Here's the sequence of what colour cartridge went in which spot.
Yellow in black slot
magenta in yellow slot
cyan in magenta slot
black in cyan slot.
then i switched them back to the way they are supposed to be and tried to print again and it worked!
the colour is amazing on this printer- i had the trouble right from the beginning after installation.
hope this helps.

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.

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!

We have a Brother intellifax 4750e. When we send a fax, there is a black streak down the right hand side of the paper. When we receive a fax, the streak is not there. The streak is about 1" wide. ...

Try cleaning the rollers with rubbing alcohol using a good quality paper towels, I find there is a buildup on the rollers causing streaking on the paper. If that fails the print head must be suspect.

Papers come out with black streeks on them from my sharp FO 4450

If everything is coming out with streaks, it's most likely your cleaning blade which is part of the drum cartridge. I've also seen this from 3rd party toner. Get Sharp toner for your Sharp fax if you don't have it already. If your black streaks are only on copies and sent faxes, this indicates that your scanner is dirty. It's located where you feed your paper in. Lift this part up and you'll see a strip of glass running front to back about 1/2 inch wide. Clean it and that will get rid of lines.

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)

Fax troubleshooting

remove any cartridges, take a can of air and blow it out, especially any sensors (which would be up under a small black piece of plastic sticking up in the paper path... that's the actuator). Once you've done that, try it again. If that doesn't work, try cleaning the roller and feed tires in the paper path with soap and water on a rag, or a gentle non abrasive cleaner such as simple green. That should take care of most jams unless its tires or clutches are worn out.

Black Smear

go to page13-9 routine maintenance section, where it says to clean the glass strip on top of it there is a white plate (shown) does that plate have ANY dirt or spots etc......?
It MUST be completely WHITE or it will give you black streaks. if it cannot be cleaned then use white out to cover. ( makesure it is completely dry before using).
