I have toner that stays on the drum after printing a sheet

Toner stays on the drum and then gets transferred on the next print. I clean it off and it still returns a few prints later. Am I missing something ?

Sections of almost invisible print. Just replaced toner, doing same thing with new toner as old.

First thing to check is damp paper....causes poor transfer of toner to paper. To verify if this is the cause, print a sheet and try to print again on the back side......if quality is OK then you know it's paper issue
Next is transfer roller...this is usually a black rubber or spongy roller directly under imaging drum....try to clean with vacuum.
After that you are looking at a faulty toner or a DC controller board....given the age of your printer it wouldn't be economical to replace the DC controller

The printing is clear but on the buttom of every page it is like a duplicate printing with grey color. What is wring on my printer or I need to change toner?

First thing to consider is a toner getting low but it can be a drum, fuser (fixer) or transfer roller. If it repeats the grey at a certain interval it's likely a roller in the fuser/fixer, the drum (light sensitive coated roller is all it is) or a failing transfer roller (it charges to pull the toner image off the drum onto the paper and hold it till the heat of the fuser bonds it to the paper). Easiest and least wasteful, and what Brother would tell you to do first, is to replace the toner. If it doesnt correct it you still have the new toner to use once the problem is corrected. By virtue of it being fine except the end of the page sounds like toner. One way to figure it out definitively is send a page while the exit door is open. Watch and once half the page is out of the exit door open the toner door to stop the printing. It wont hurt anything but will allow you to see the end of the sheet before it goes to the fusing unit. Of course you need to be very careful removing the sheet to prevent damage to the fuser. If you get the grey on the bottom of the sheet during the half sheet test I mentioned then it's in the image creation and transfer, not the fuser/fixing stage. Replace the toner and try a full sheet. If corrected it was the toner. If not then the drum or transfer roller would be at fault. Drum is user replaceable and while expensive it's another item you can store back on the shelf till you need it if the new drum doesnt help.Transfer roller needs to be replaced by a service person.You could do it but you would need to have the section of a service manual to show you what to do.

I'm getting ghost images on multi prints to the point it is unreadable, is this the drum or fuser?

The only way to tell is to start a print and power off when print is still inside. If you see the ghost before the fuser it's the drum, if clean before the fuser, it's the fuser. You can also open the back door and look at the fuser roller with a light, the fuser roller should be clean but if the roller has images it's time for a fuser.

Our copies are streaky like the drum is not clean.... help! There is black streaks on the top of all of our copies on our canon imagerunner 3300.

A) Black Streaks, Shadows, And Ghosting
Adjust the printer's lightness/darkness setting to 2-3 different variables and see if problem disappears. Look at the fusing assembly - is the roller torn or does it have any black buildup? Use caution!!! It gets HOT!

Try another toner also.

What is the difference between a toner and a drum on a BB4400 OKI printer?

The toner is the black powder which the printer uses to turn type and pictures into a printed piece. The drum is the device that actually fuses the image to the paper. Toner cartridges and drums have a service life. Toner cartridges will have say a 3000 sheet capacity. When it is empty you replace it. The drum will have a 10-20,000 sheet capacity. Typically the drum is three to four times more expensive to replace. Many companies will give you a credit for turning them in vs ending up in a landfill.
Good luck.

Toner mess on one side of paper dell 1720 printer

The transfer roller may have toner on it that is making that mess. Remove the toner and drum, look inside the printer, there is a grey roller towards the back of the printer. Is there toner on the right hand side that corresponds to the print out? If there is, cleaning it may only make it worse. Replacing it would be the best solution. You would want to make sure that the drum is clean after replacing the roller, if it is not ,then it will transfer to this roller once again.

Pages full of toner / toner streaking

First off, this is a comment from a random person who may or may not know ALOT about these printers and toner/printer design in general. All toners are not designed to the same specification. Toner is a combination of plastic "pigment" and iron like shavings to make it magentically attracted to the electrical charges within the unit. Different toners conform to different grades and mainly size of the particles within the blend. The manufacturer doesnt only recommend that you use their toner to make them money, yes of course it makes money, but its because when the unit is designed it is designed to use a certain grade of toner, trust me if you put the non-branded toner vs the branded toner under a microscope you would see quite a difference. Often the non-branded toner is much larger in particle size (obviousely because its cheaper to make at this spec). This causes a variety of issues from excess toner not being cleaned off of developer rollers, IDT rollers, or clogging of toner dispenser tubes in the unit and the micro filters contained at the toner dispenser assy and developer assys. Also as for the issue not changing when switching to dell branded toner - the dispenser tubes within this unit contain up to 500-1000 pages worth of toner, making no change in toner you make immediately visible. Also depending on the damage caused by the previous toner, it may not be able to be fixed until all the components in between the toner and final delivery (drum cart) are replaced. In this case more than likely the toner dispenser assy, all developer assy's, and drum cartridge need to be replaced, and than be sure to stick with factory branded toner :)

Printing Quality on HP 4550 Colorlaserjet

most likely the OPC (drum) or sometimes called "image drum or transfer belt located in the top draw. this is a consumable that needs replacing after it's life cycle is over. sometimes it will go below or over the life cycle, it all depends on many variables.

I would take out all the consumables, toner, belt and so on and use a dry cloth and small vacuum to clean the inside of the printer, then test it again, but when you have streaks it is usually the transfer belt. other possibilities is the scanner/laser window inside, sometimes it gets toner on the glass.

but step 1 is the Transfer Belt/Drum

hope this helps
