SOURCE: Konica Minolta C450- error code c-2251

It's been a while since you posted that but you may just need to slide it back out and shake it back and forth (long ways) a few times. We had the same problem and the konica minolta tech told us to do that. It worked. DO NOT turn it upside down though.

SOURCE: replaced drum unit and came up with error code

c-2251 - K PC Motor’s failure to turn
The Motor Lock signal remains HIGH for a predetermined continuous period of time while the Motor is turning.

Reemove the unit and try to rotate the drum and the developer gears by hand, you should be able to rotate it fairly easy.

SOURCE: Toner problems with Konica Minolta 2450

very annoying message i agree - most likely caused by toner dust.

The printer uses a carousel to rotate the toner cartridges. Dust and toner can easily spill as the cartridges rotate. The error can appear at any time but seems to be most annoying after a paper jam or other error. It is also important to make sure that the cartridges themselves are clear of toner dust. Pay particulair attention to any copper contacts on the cartridge.

SOURCE: machine gives me C-2251 error code after replacing

If the drum units have been in storage too long they will bind up a little.

Lightly tap the drum unit on the ground. Look on the back of the drum unit and locate a white cam gear. Take a pair of pliers an rotate this gear until it moves more freely.

How do i override an empty color cartridge so that I can atleast print in black?

There is an error in the control logic of the printer that you can exploit like this:

  1. Start printing your document, you will receive the error message "missing toner"
  2. open the front door and close it again, this will reinitialize the test cycle
  3. the printer will now print one page before verifying the toner content again
  4. after one page you get the"toner empty" message again. Reopen the door and close it again to print another page.

This is only an emergency workaround if you really need to print something black urgently, in the long run you still have to buy a new toner.

Remove all toner cartridges

It took me some time but I found the sollution:

Remove the powercord from the printer.

Open the front door and remove the first toner.

Close the front door and open the top door, remove the photo conductor.
When the front door is closed, you can turn the toner trommel and move it so that the second toner gets in the remove position.

Open the front door and remove the toner.

Close the front door and turn the trommel.

Repeat those steps until all are removed.

Yes, open and close front door. And or power off both power switches. Wait ten seconds then turn it on again. The code is for the black image unit lack of toner. Check the image unit, and ensure toner is installed. Model type? would also be welcome

Error code on panasonic copier fp-1670

Welcome to Fixya.
Hopefully we can answer some if not all of your questions.

An E3-01 is an error code for your toner hopper. Did you just recently change your toner bottle?
If so, open your front door, take the toner bottle out. Close the front door, turn the machine on, and let the machine cycle and stop.
After the machine is stopped, then open the door and then place the toner cartridge back in.
Close the door, and if the error code doesn't come back your problem should be fixed.

Let me know if you have any other problems.
Good luck
Please post a rating if I have helped you with your question/problem.
have a good day
Mac =)

Dell 1720dn Error and Toner light on

After replacing the drum unit you have to tell the printer that you've done it(it's not smart enough to figure it out itself). Have the front door open and press and hold the Cancel button on the printer until all lights flash in sequence then let go. Then close door and try.
