Question about Brother DCP-7020 All-In-One Laser Printer

Toner not fixed to the page, rubbing off

Having replaced both the drum and toner recently, I don't know which caused the problem. Now, images that print on page can be smudged off to the point of not being readable because they are too faint. Does anyone know which is defective: the toner cartridge or the drum? Thanks in advance.

    It seems to only be a problem on my gray envelopes that match my gray letterhead (25% cotton paper). Printing on white paper or white envelopes seems fine.
    Is this something that can be adjusted? Can the fuser be replaced? Or is this just something that wears out over time through constant use?

    Thanks again. At least I am avoiding chasing a solution by replacing toner and drum cartridges, which would have no effect on my problem.

    White envelopes are Staples standard white envelopes, 24 lb paper, white "wove". No cotton apparently.
    Thanks in advance for any help. I'm lost.

The fuser (a large roller near final exit that is heated) is not reaching proper temperature. normally, it should be too hot to touch.

    are the white envelopes also 25% cotton paper? I want to narrow down any derivatives. Don't do anything with fuser yet...

I have an HP 4515 that is printing blank pages. I have tried to replace the toner and the power supply board. Neither resolved the issue. When the paper gets deliver out the paper is warm. This occurs when...


I believe I understand your issue:-
The printer is able to come to ready- your still able to navigate the menus. the printer goes through all the motions of printing except producing an image-
Having the machine print a test page ( internal Print ) tests whether the formatter is still able to generate a digital image ready for the print engine, but does not diagnose the print engine-
1) power down and remove power cord
2)remove the toner cartridge, use a pair of pliers and gently rotate the drum ( within the toner cartridge, a drive gear/mesh can be found on the end of the toner unit)- are you able to turn this drum or has it seized?
if it doesnt replace the new toner with another NEW toner and try again
3) return the power and power up the machine having first disconnected all network connections.
allow the machine to come to ready.
4) ask the printer for a config page ( internal print) and estimate when the paper is immediately below the drum surface ( toner cart) and using the power switch turn the printer off- causing a jam in the centre of the printer - this is ok we do this to see if an image has been generated on the drum surface- remove the toner cartridge and slide the drum protector plate to the side, look carefully at the drum suface ( you should see a latent image of a config page, at this point look at the paper still jammed inside the printer and see if there are any signs of toner ( there should be part of an image allready on the surface ) now if there is an image on the drum but no image on the paper then I would replace the transfer roller and or transfer HVT power unit, if however there is no image on the drum then you have a very serious problem which will require a new laser unit ( but this should really come up with a diagnostic error code)or Primary HVT unit.

Checking the toner cartridge
Image formation defects are many times the result of problems in the toner cartridge. If there is any doubt, always replace the toner cartridge before troubleshooting image defects.
Use the following checklist to make sure that the toner cartridge is still operable.
" Make sure that the toner cartridge is seated properly.
" Inspect the toner cartridge for toner level.
" Check the expiration date stamped on the toner cartridge box.
" Check the toner cartridge to see if it has been disassembled or refilled.
" Inspect the toner cartridge to see if toner is leaking through worn seals.
" Check the surface of the photosensitive drum in the cartridge to see if it has been damaged or scratched. Touching the drum contaminates the photosensitive surface and can cause spotting
and image defects.
" Blurred areas on printed pages indicate that the photosensitive drum in the cartridge has been overexposed to light. Because overexposure to light causes permanent damage to the photosensitive drum, the cartridge should be replaced.
Note A toner cartridge weighs approximately 863 grams (30.5 oz) when it is full, approximately 766 grams (27.0 oz) when it first fades, and approximately 742 grams (26.2 oz) when it is empty.

To redistribute toner in the cartridge

Before installing a new cartridge or when toner begins to run low, redistribute the toner by rotating the cartridge back and forth five or six times.

You may still be able to do a printer selftest page.

Press the large button on the printer.

Look at the pages for

Toner
Imaging unit

The Imaging unit may be at end of life.

This is the drum unit and collects the waste toner.
Whilst you can just reset the drum counter (see user guide for this E120, it can lead to problems if you don;t replace the drum unit. I've seen E120 drum units packed full of waste toner, to the stage where they won't take any more, and it just spews all over the mechanism. It's a very small waste collector (but its also a very small printer, and relatively low capacity toner cartridges (1k, or 2k).

Remanufactured drum units for E120 can be found on the usual internet auction sites.

Laser printer horizontal streaks go away after a few pages


The operating principles behind laser printers are fairly simple. In fact, Brother machines more closely resemble large copiers than conventional laser printers, this is why they are so reliable.

There are a couple of things to look at:

On the drum unit: is the imaging drum worn or scratched? When did you last clean the corona wire?

If the drum is scratched or otherwise with defect it should be replaced. If the corona wire is dirty it can fail to properly charge the drum and lead to print defects.

On the toner cartridge: Does the toner roller have any noticeable lines or banding in the toner?

Behind the toner roller is a "Doctor Blade" that ensures an even and consistent coating of toner. If there are lines in it they can produce print defects as well. Lines would be likely caused by toner accumulation on that blade. If there are lines, are you are careful, you may be able to clean the blade by gently and slowly scrubbing the non adhesive end of a post-it note between the toner roller and the doctor blade where the lines are.

Brother MFC-7420 just started printing a shadow image


Sounds like a bad drum cartridge. Pull the toner/drum cartridge out of the machine and set it down. Press down on a (blue?) tab to release the toner cartridge, and you can lift the toner cartridge out of the drum cartridge. There is a cleaning blade in there - a soft plastic blade that rides against the drum and scrapes off toner that didn't get transferred to the paper. If it gets stuck off the drum surface, images repeat a few inches (one drum circumference) down the page.

A new DR-350 drum unit should fix it. have the machine's power on when replacing it. While the door is open, touch the CLEAR key. The display will read "REPLACE DRUM?" or something like that. Press 1 for Yes.

HP Laserjet 2820 Streaks on Page


Hi,

There are 3 parts to the imaging process that could cause your issue. You have the toner (x4), the imaging drum unit (Q3964A) and the fuser unit. If you are getting streaks from all colors, one or more these parts are the issue.

Let's start with the easy stuff:

Open the cover as if you were replacing toner where you can "visually" inspect the toner and imaging drum. Pull the drum out and pull back the "plastic shutter" on the top, this will expose a green drum CAUTION! Too much exposure to light and touching it can cause damage. Just take a quick look trying to see if any of the lines on your page match any marks on the drum. Check the bottom half of the unit as well there should be a white section across the bottom, expect that as well.

Next look at the toner, if you can look at any other color but black it will help you look for the streak marks a lot easeier. If you couldn't see any streaks on the drum on toner cartridges, it's time to look at the fuser unit. Power the machine down and turn it around, unplug it then fold down the blue clips and CAUTION! the fuser heats the toner to the page so if it's been used recently it may be hot. once the clips are down, just pull straight back and look for the streak marks.

Sorry for the book, but I hope it helps.

Deteriorating image quality


Good Evening Robert,

The setting for non dell toner only controls the fuser temperature, and will not cause you any print quality issues. Toner is actually made up of ink and plastic. The fuser melts the plastic to "fuse" the image to the paper. Dell toner is set to "fuse" at a specific temperature. when you use non Dell toners, the temperature required to fuse may be different, and when set to non dell toner setting, the fuser temperature is raised to the maximum to ensure the other toner fuses properly. The down side to this is that you will wear out the fuser sooner then it should.

As far as the print quality issue you are having, it is most likey caused by the imaging drum.

Regardless of the estimated life for the imaging drum as stated by the printer, this is just an estimate. Many things can and will cause the imaging drum need replacing. ( Just yesterday I replaced a black toner in a 3115 that was less then a month old... genuine Dell... with more then 75% expected usage left because it was defective).

On this printer, each of the 3 colors and the black are all independent of each other with the exception of the imaging drum. Even within the imaging drum, cyan and black are independent of magenta and yellow on the first stage of transfer. When you have deteriorated print quality that effects more then one color, the first step is to replace the imaging drum.

The Primary transfer, secondary transfer, and tertiary transfer of the image are ALL contained within the imaging drum.

The chances of having 3 or 4 bad Developers is very very slim. If your print quality issue was related to only ONE color, then I would say you had a bad developer unit ( the 4 items located behind the imaging drum when removed). These are far more difficult and expensive to change.

The BTR ( bios transfer roller ) is the only other item that "could" effect your print quality, however, based on the symptoms you discribed, I doubt it. Besides, if i am not mistaken, the imaging drum kit comes with a new btr anyway.

Although I am sure you may be disappointed with the fact the drum unit is failing while showing it still has life remaining, the solution to replace it should restore your unit to full operation. The unit is light sensative, and effected by physical age as well as the number of prints it has supplied.

Please evaluate the solution i have provided and, rate the solution appropriately to show your support.

Thanks,
Cory

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 :)
