I wish to replace the black toner cartridge in the Dell 3010cn. How do I gain access to it. There is easy access to the cyan cartridge at the moment

You may have a bad drum cartridge. Is it refilled? Try replacing it with brand new original.

If there are debris of "black film-like material" you may need to replace your fuser film.

these syte explain how you can reset problem, http://www.zinetic.co.uk/video/dell3010drum.aspx

are you using a dell-branded toner cartridge? if yes, then you should replace the toner cartridge sensor and machine control unit (MCU). if no, you can enable the non-dell toner mode on your printer's operator panel. how? press menu, down until "configure" & press select; down until "maintenance" & press select; down until "non-dell toner" & press select; down until "on" & press select.

A vertical line on laser copiers which are the same lenght apart on each indicates a dirty or defective toner cartridge or dirty or defective rollers. Take the cartridge out and wipe the rollers with a soft cloth. If the streaks continue then the rollers inside the cartridge or damaged. You will need to replace the toner cartridge. Let me know if you have any questions. Please rate this solution with 4 diamonds.

There is a manual removal option. Open the front cover. Then the top. Remove the drum. Close the front cover. (leave the top open). Move the toner housing unit so the required toner is accessable from the back. Remove.

Replace drum. Restart printer. The housing unit shoud rotate the empty spot to the front so you can insert the new toner.

Good luck.

Try a new Cyan toner cartridge. If nogo, will need a new transfer roller or transfer belt (I used to work on these printers but forgot if they use a belt or not... I will check on the DCSE site and post back)

um... Cyan is blue isn't it?

Magenta Pink,
Yellow = Yellow and
Black = black.

Depending on which software you are using for documents, you should be able to select output color from within the program; i.e., in Word, you can change the default template to whatever color you wish that is offered on the pallet.

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 :)

I had the same problem and found that one of the toner cartridges must have not been seated properly. I removed the black toner cartridge and re-fitted it. The printer now works fine again with no errors. 17H is a code relating to a fault in the rotation ......... possibly one or more toner cartridges need checking. Use the menu on the printer to turn it to the appropriate position (i.e. engine menu then select replacement of whichever toner you are checking).
Hope this fixes your as well.
