SOURCE: Cyan Ink not printing

The important part of question is the word "refilled" Remember that the cartridges come pressurized from the factory so when refilling you are taking a chance as to whether the cartrige will preform as expected. That is not to say that it should not work but I am sure if you replace the cartridge with a Lexmark approved cartridge the cyan will work.

Good luck! Dont forget to rate my response!

SOURCE: Cyan Toner always prints faded.

It is the developer. All colours should be changed at the same time. This can be accessed via the right hand side of the machine, when you remove the cover. (where the output tray is)

Hi Vinay kumar kuchipudi , I tried using refillable cartridges and my CYAN is always flashing . rest of the cartridges is reconised. Can you please advice me what to change. I tried the second new ref


Sorry for the delay.,
As you know each cartridge having memory chip, the chip keeps the estimated level of ink inside as per the out put print volume . But there is no contact or any internal circuit to link up with the chip.. Once its empty, even refilling the ink inside chip wont recognizes the ink level, results printer detects that cartridge running out of ink & printer warning appears on panel. You need to replace the chip while refilling the ink. Now a days universal re-settable chips are available in the market, get the set of chips replace with existing chips..

Bizhub c451 error code c2259?


Black developer motor failure to turn. You mite try pulling out the Black image unit and shake it to spread the toner and developer along the whole unit. The image unit mite have been stored standing up image units should always be laid flat. All the developer may be sitting at one end of the image unit an so the motor is having a difficult time turning.

Instead of Bule print DC12 prints Violet


Hi there! The blue color is becoming violet because the Cyan and the Magenta toners are not getting mixed in the proper 100:100 ratio (100% Magenta and 100% Cyan make CMYK Blue). Since the print is violet, the culprit is the Cyan toner. Now, first, get the Cyan Developer Assy checked if there is enough developer in it. If no, get it refilled by a proper tech and manually mix about 50 grams of the Cyan Toner with the developer. Also get the tech to check the trimmer gap on the Developer Assy with a metering gauge. If yes, next check the Cyan dispenser motor located on the backside of the Toner Housing Assy. It is probably broken and not dispensing any toner to the Cyan Developer Assy . Additionally, check for the Cyan Dispenser Auger blockage or jam. It is located under the Cyan Toner Cartridge in the Toner Housing Assy and also check the auger under the Cyan Developer Assy. After sorting these out, you should get proper CMYK blue from the 10th or 12th page once you resume printing.Let me know. Regards

I have a SHARP al-1661cs copier/printer. i keep getting a "replace TD cartridge" message. I have replaced the cartridge and it still come on every couple of days. i take the cartridge out, shake it and the...


Are you having your cartridges refilled?
By "replace TD cartridge" message do you mean the little stack of 6 red dots on the control panel?
The sensor for this condition is contained within the toner cartridge. The sensor reads the mixture of developer to toner ratio and tells the machine to add toner when needed. If you are having this problem with 3 different toner cartridges then I would suspect the toner add drive system. If you are having just the 1 cartridge refilled and have had the problem with the last 3 refills then the cartridge itself may be the problem.
I'll let you repond then we will see if further info is required.
Thank You for using Fixya.

Large Toner Streak... Bad Imaging Unit?


Check to see if you waste toner recycling for the cyan is working or being blocked. Check the transfer bias roller next to the cyan drum. Return you cyan imaging unit for a warranty replacement. Check for obstructions to the cyan developing unit. Check that the cyan IU was put into the machine properly. Check for toner leaking from the entrance to the developing unit or from the toner cartridge.

or, call a qualified KonicaMinolta tech to check out and service your machine.

Toner not detect


If you refilled it then yes, you would need to purchase this chip as it is telling the printer that it is out of toner.
