    Need help installing Dell 3100cn as a network printer on windows vista. I have an IP address but it does not recognize it when using the setup wizard.

    I've had the same problem. The 3100cn keeps asking me to replace the black cartridge even though I just put a new on in.

    3100cn, replace the black toner cartridge and it prints a few pages fine then goes to "ready to print" with "insert black toner (k)" flashing below. Send a print job to the printer and it goes to "processing" then to "insert black toner (k)" and quietly and does nothing. Replace with another new cartridge, leave it out for 10 min., turn off the machine for 10 min, reinsert another new one and the same results.

    Been using Ld refills for a year now Ld is sending me the third free replacement. What do i do to fix this problem?

    I have the same issue. I just bought a new dell toner and installed it into the printer but the Replace black toner message will not go away. When trying to print it says replace black toner.

We have several 3100cn were I work. One has the above symptoms: very long calibrating cycle followed by the replace black toner message. I thought I could fix this by exchanging cartridges between the two printers to find the culprit. No success.

I then started looking for mechanical differences between the two printers -- and noticed that the roller BEHIND the black cartridge (take the cartridge out, look into the printer, and you'll see a partially hidden horizontal roller, perhaps part # C5396 2nd Bias Transfer Roller Assembly) was much more wobbly on the bad printer. I've yet to replace it (does not look easy), but I think this is the culprit.

After installing the toner cartridge the replace toner message will reappear after the calibration sequence until you press the menu button on the front of the printer. After doing that the message goes away and you should be ready to print again.

Dell 3100n keeps saying "Change Black Toner" even

Before installing a new toner, put a disposable towel over the ink toner exit, and shake your toner lightly back and forth and up and down. Make sure your toner cartridge is in the open position before replacing it in your printer.

If you are using a refillable ink cartridge, make sure you are resetting the cartridge using the method described by the refillable manufacturer.

If this does not answer your question please request more information before voting on my answer. I will try to find more information about your toner cartridge that will help you futher.

Try the cleaning rod. visit:
for images (under replacing the "cleaning rod pad") for where to find the cleaning rod. You likely don't need to replace the pad, just use the rod (pull out and push in 10X) and try to print again.

Hi, My Dell 3100CN printer is displaying "Change Black Toner." I have replaced the toner cartridge. The printer begins to calibrate for a very long time. When it finally finished calibrating, it return to...

There is a chip in each toner cartridge which tells the main machine something about how full it is. It may be that it tells it how full it is, or it may be that it tells it how many pages it has done. It sounds as if the new black cartridge has a duff chip, and is telling the main machine that it is empty. To test this, you can overide the message. 1. press on the menu button;
2. select configure;
3. select maintenance;
4. select non-dell toner;
5. set the value to on.
If that does't work, get back to me.
