[CQ] Black Dev in Colour Dev Units

[Leebs14]

We were asked to do a chargeable service call in our area by another dealership a few hundred miles away on a MX2610, they said the machine needed new cyan Dev, new drum and charge kit and they would send the parts.

When our tech got onsite he found they had sent black Dev, when he queried it they told him they always use black Dev instead of colour Dev as the cost saving is huge and you simply run 150 test copies of the test chart or some sky shots and it will add toner and be ok, he did it and said that after about 200 pages the print quality was good and he then ran the 25-02 on the cyan and all seemed to be ok.

We've never come across this before, on the face of it I can see the cost saving, has anyone else got experience of this?

That's pretty crazy. But I huge savings, and a timesaver if you don't keep color developer stocked in your car. I might just have to see what happens using an old junk machine

Interesting, let us know, it really sounds crazy to me too.

Re: Black Dev in Colour Dev Units

On a Kyocera I've saved magenta developer after the enduser installed cyan toner into the magenta toner port, and tinted all the prints purple. I simply created a 70% fill magenta electronic original with a nice large lead edge void, then sent it to print in batches of 50 (twice) then batches of 25 (again twice). As long as the developer was in good condition at the beginning it will tone back up to magenta just fine. It's a bit wasteful of toner, and your time if you count the 45 minutes spent fiddling around making black developer to magenta, but sure ... it's possible. Does the $100 labor and wasted toner, end up saving you much in the end? I doubt it. =^..^=

Valid points sir. Thanks. I was going to try it with boneyard parts on a boneyard machine whilst doing other stuff at the shop. I'm only thinking of emergency stuff.

Sharp colour Dev is hyper expensive so I can see the attraction as the black Dev is very cheap. My tech's view is the devs the same just mixed with the relevant toner to make it the right colour, I've seen the test prints after the 25-02 and they are really good.

Did the test on a MX-2614. Took 250 Sky shots for the Yellow to purge in and replace the black but it worked.

It really sounds crazy to me, but i will test it

Re: Black Dev in Colour Dev Units

I will test as soon as I have chance ....... makes sense. So much sense (cents) and so obvious I'm ashamed to say I've never thought or tried.......

Re: Black Dev in Colour Dev Units

Just do the normal PM setup and simulations. It will work.

The image sensors only see the density not the color. So the developer with no toner should be the same used for the colors.
Then the only problem is to get the black toner out. Work well on Konica Minolta. Except for the image that seem very dark after.
Fine for office color but for graphics a slight problem.

Re: Black Dev in Colour Dev Units

add:
My opinion is that the toner color and black and white at the SHARP on all the latest models of the same.

According to the developer:
The black DV MX2610 unit he cast black DV MX27FVBA. by weight for 2610. All the works. SIM 25-2 was successful.

Re: Black Dev in Colour Dev Units

Let me get this straight... , so you put black dev in ..let's say magenta dev unit ,run 200 sky shot to empty the black toner and then sim 25-2, but if your dev is fill with magenta toner it should pop a ee-el code ,, no ???
