Question about Dell 3000cn Laser Printer

1 Answer

Printer leaves a grey haze on the page.

Printer makes not just the printed words dark but there's a grey haze on the page. So it looks like we're printing on light grey paper, but we're not. It's white! And when I open the machine, there's black toner everywhere. Help help!

If your fuser is not failing then someone probably didn't install the toner properly. Regardless, it is incredibly hard to clean toner out from all the guts and the gray won't go away as long as it is there. I would take it outside, wear a smock, and blow it out with an air compressor or half a dozen cans of compressed air. Wipe down and clean every part you can.

Replace the toner cartridge. Then run a couple dozen copies of something to pick up the remaining toner from the internal mechanisms. See if their is any more toner. If there isn't...then somebody messed up and you just need to work the last of the toner out of the innards.If there is more toner after you clean it out and replace the toner cartridge, start thinking about replacing the fuser.

How do I clean the toner


Sounds like a poor quality toner was put in your cartridge. If you are using remanufactured cartridges see your remanufacturer for a replacement. If you are using OEM cartridges contact Brother directly and they can sort out the issues and supply replacement cartridges.

Black in coming out grey


Ensure that cartridge are not refilled, then only you do the following process:>Got to printer properties>printing preferences>color>select print in grey scale>apply>OK.. Then check..Reason why its act like this: In printer properties if its selected as print in color, printer mixes colors to create black(which is visible look like dark grey).Select in properties as above said before clicking OK for the print command, then only printer uses mono cartridge..

I need to print on 9 x 6.75 pages, with the wording along the 9" side. I cannot feed the sheets into the printer with the longer edge leading, as 8.5" is the maximum it accommodates. To remedy...


it not only depends on the printer, but on the software you are using to do your text. if you are using office, you must choose orientation manually. If that doesn't work, and for example you are using word art, just leave the page as it is by default and rotate the text. Again, it all depends on the software you are using

Prints lighter on left side of most pages. Even with new toner and fuser and toner darkness turned up to 9 or 10.


This is a bit tricky, but try it

remove the toner cart and lower the top cover about 1/2 way. Look inside and you will see 2 grey rollers hanging from the top on 2 arms. Move the right side arm to the right and grey rollers will fall out (they are as wide as a sheet of paper)
use a light scrubbing with a damp cloth to remove the grey, the rubber should be a tan colour. Dry them off well, insert the left side first (cover in the 1/2 closed position makes moving that right arm easy. install the toner cart again and print a page. It should be nice and dark now, just make sure the rollers are dry when you reinstall them.

I am trying to print onto pre-printed forms which have a dark blue band at the top. My printer isn't recognising that the band is there so is starting to print too far down the page. Help please!


This type of problem can usually be resolved simply by adjusting the margins from within your word processing program. Depending on which word processor you are using you can go into the page setup and make these changes. For Microsoft Word go to the "File" tab at the top then to page setup. The first tab that comes up will allow you to change the margins on the page. If the print is too far down try reducing the top margin from one inch to 0.5. If that is not enough reduce it some more. Print test pages on regular paper, then hold them up to the light against the paper with the pre-printed band to see how the print lines up. That way you don't waste the expensive paper!

My hp laserjet 5p ..The printer prints grey and dark grey line about every 1.5 inches. it looks like it lightly duplicates what it has already printed, with every 1.5 inch pass.


Most common and easiest to check is the toner cartridge. Swap it out and see if it goes away. If not then it is in the fuser unit. The fusing unit is the part that gets hot and is located right before where the paper exits the machine.
If the bands go all the way across the page then the toner cartridge is much more likely.

Dell 1815dn laser printer prints completely black pages


1. Charge – Print Quality (PQ) -- The charge roller evenly distributes a negative charge on the photoconductor (PC) drum. This evenly distributed charge acts as the film that is discharged (exposed) by the laser to create the latent image.
a. Print Quality effected: Faint, Entire Black background, Grey Fog/Haze
b. Parts Involved:
i. Drum -- A drum cartridge is coated with a photoconductive material that allows electricity to pass when exposed to light. As an example of why this can be the failure, if you leave a drum out in light long enough, you will get dark backgrounds or just black pages. However, drums do wear out over time too; specifically the photo material the drum is coated with. As this degrades, more of the positive electricity on the inside of the drum gets through and grabs toner, as if the laser wrote to every square inch of it. A damaged or defective PC drum can cause black streaks/lines, voids, speckles and various other print quality problems.
ii. Charge Roller Also known as the BCR or Bias Charge Roll. The charge roller pulls double duty. It energizes the outside of the drum with negative energy and as a result it cleans any previous latent images. If the charge roller were failing to energize either due to the HVPS or the charge roller itself, it wouldn’t clean any previous unused toner deposits from the last revolution would start to accumulate and appear on paper more and more causing haze. A missing charge roller causes completely black pages.

iii. HVPS – High Voltage Power Supply -- Responsible for charging components such as the inside of the drum, the charge roller, and transfer roller. If the HVPS does not give enough to the charge roller it can fail in erasing the drum, causing entirely Black pages to be printed.
