Black toner in the Cyan slot

Re: Black toner in the Cyan slot

It's all too possible, the reset boards on the toners don't prevent incorrect insertion anymore that is the sole responsibility of the cap fins now.

I've also taken incorrect version black toners in an emergency and swapped the cap over from from the declared and stopped empty to the full bottle, fitted to a C554e and it still reset the life counter with the original reset board from the empty toner still attached.

I think the main purpose is to prevent the situation like in the c360 series where you have a never ending toner low warning if someone changes the cartridge part way through life in error.

Exactly. Its just a stupid fuse this great chip
We have machines now with toner near empty OFF, as this was happening too often when toner was changed prematurely.

That's interesting--especially the caps portion.
For the record, I meant to put an escape clause in my comment of "at least for older models" because I have very little experience bh4 series.

You mentioned the c360s and a persistent low toner message. The chip certainly has a part to play, but doesnt the hopper dictate when the toner is low?

I accidentally swapped K and M dev units on a c7000 once. Couldn't figure out why my test patterns were so weird.....

Re: Black toner in the Cyan slot

I am not looking for help here. I just had to share this with you folks. A tech showed up to a call on a C454e for "dark prints today". Prints his halftones out and the Cyan one is black LOL....after a few seconds he checks and finds they managed to crank that black toner hard enough to make it fit into the cyan slot. No codes, no errors, just "dark prints" lol

It is possible to do the same with the bizhub c227, the customer put black toner in the magenta slot ... as he said, it offered little resistance, but it came in and stayed working, but now burgundy instead of magenta
