I have 3 c654. We run them pretty hard. With no problems. Recently we have been printing lots of postcards/double sided with large pictures on them. The Cyan IU are failing at half life. They are maintained and all sensors cleaned. I do manual toner add as much as I can. I still feel like the toner hoppers are running a low. Gradients being done every day. What else could be causing the developer suck? Can I make any adjustments for increasing toner add? Firmware has been updated. I am at a loss and about to spend 50k on 3 C7000. Help

Re: C654E Cyan devloper suck
Does the machine code out?
If it is the case that it cant get enough toner on time the TCR level will fall below 4% and an error will be given.Whatever -
Re: C654E Cyan devloper suck
Are you resetting the image units?
Make sure all the image process adjustments are on default.
What is the TCR value under <state confirmation> <level history1>WhateverComment

Re: C654E Cyan devloper suck
When you say "add developer" , I'm assuming you are talking about aftermarket developer because I'm not aware of any dev from Kon/Min for that model? Are you using genuine K/M toner? If you are using aftermarket of either toner or dev that is your problem. I have never had good results with aftermarket, especially developer.
I'm assuming you are a print shop, if so that is more reason to use genuine supplies to maintain consistent print quality to sell to customers. "pay more now, or a lot more later"
I have print shops with that same machine. They run big jobs on them, mostly 12x18 thick stock. They use genuine IU's and toners. They chip/reset IU's at least once. Not sure how much more you would expect from these consumables? I have one C654 (reg paper) with 1.5 mil clicks and have the same color IU's, fuser etc. Have only changed black drum a few times.Comment

Was assuming u got the developer from old tanks?WhateverComment

Re: C654E Cyan devloper suck
Yes, using developer from old units. They are sucking developer at half life and then going south. I see the issue more of a toner lack?, Hopper units seem close to empty. There are older IU in the machine lasting double the life. We are not setting them just running them.
Its the large pictures on the prints that is causing this. Do not have a problem when we ran normal text.Comment

Re: C654E Cyan devloper suck
Well TCR values are all at 0, Im assuming because of the graduation and cleaning I was doing yesterday. I printed 40 copies with lots of color. All values now at 6-7
I will run them the majority of the day tommorrow and re test
Because one side the postcard is multiple large and random pictures.... will developer wear out sooner? causing the Electrical charge on the imager to increase and release developer? Just as occurs when in at end of life cycle when the developer is shot?Comment

Re: C654E Cyan devloper suck
OEM toner has developer in it so it does not run out.
i only see issues like this online from:
leaking white bushing(s) rarely
non OEM supplies frequently
running a drum over 175-200%
bad front side board.
mainly dirt-in-a-bottle aftermarket toner.
good luck.We know a thing or two because we've seen a thing or two.
The medication helps though...Comment

Re: C654E Cyan devloper suck
I only use OEM. No IU leaking. We are talking 50% usage and failure. Nursed along with DV from other used OEM units. Front side board on all 3 units at once? Possible. All printers are on there own circuit.
Best way I can describe problem, my guess is toner being used faster than resupplied. cyan dev suck when low on toner. Any way to increase frequency of Stabilization during print? I add toner manually and hopper 2 times a day.Comment

Re: C654E Cyan devloper suck
maybe if right before big runs you can try initialize and stabilization and gradations.
give it some fresh numbers to work with.
there is also something to select quality over production which may pause more often to add toner and auto-stabilize? i forget where that is.
also maybe this?We know a thing or two because we've seen a thing or two.

Re: C654E Cyan devloper suck
Resting the units in some machines sets the aging compensation back to default. If the compensation runs out of range on overused tanks....WhateverComment
