    Not officially.

    However you can buy after market crap if you want to ruin your machine!

    We're having good results with dev from copylite on c220 series. Likely same dev in both series. Same gram weight in bag, used 4e dev in c220 all colors working fine. Some c220 Y overtone/dusting prematurely, like 20k. No resolution there yet. Good drums, ITB not at yield yet.

    Had to switch to Ktn developer. Clite Dv was unpredictable. You can use C220 series in a 4e, just pull out the initial toner with aboout 30 halftones at 255 after setup is complete to get the 4e toner in & the c220 toner out. DV is the same. NOW Ktn has 4e color DV' available as of 1/20... It's more expensive but would have the 4e toner in it already.

    hello im posting this for this ongoing problem I have had several machines that have depleted cyan dv on several machines thru the years so i found less expensive solution take your old cyan dv units empty all the dv out in plastic bag. Then go to a problem machine that has a cyan dv code or low cyan CQ OR not correct TRC level vaccum out toner white caps and add 3oz of cyan dev in dev unit turn drive gear correct way to form brush then add 1oz of cyan dv in unit run gradiation.
    I have tried on several machines in yellow problem, black issues and most important cyan problems i get about 30k to 50k more before comes back i saved alot of money in cyan dv units purchased hope this helps

    I've had a few machines lose Cyan (and Black) developer units in this fashion...never was a fix for it, although the idea was that the units were losing bias/voltage and had to do with removing the HVT assembly and find the offending contact point and fix it... never tried it myself; was always a better idea to replace the whole MACHINE than to risk $600 Developer units, only to find out it didn't work anyway...

    You can actually use the waste toner to top up the depleted dev units.

    Since this is where the dev ends up simply tip out a pile of the the waste box onto a large sheet of paper & top up the dev unit, stopping to rotate the unit then top up again until you have good coating of dev on the roller, it takes about a small coffee cup full.

    The dev coating will look brown ish but when you fit the unit back in the machine run full bleed gradation patterns this will pull out the waste toner replacing it with cyan toner & leave the developer behind.

    This is not ideal but was a church who had some urgent printing to do, it took about 50 duplex gradation prints to return to normal.

    See before, during & after example below.

    Well THAT'S just a pain in the butt! But I never thought to try it because of the mix of other colors. But in hindsight it might have actually worked...
