Excessive Toner Consumption

[expom]

Can any one else please tell me if you are experiencing excessive toner consumption on the Kyocera color copiers? We are only getting a return yield of around 30% color and 50% mono of the stated yields,even though the toner coverage reports are saying that the coverage is between 4.6-6.2%.We know that they use a % for cleaning/calibrating but this is excessive.All the machines have the latest firmware as well as all parts and consumables(Genuine) have been changed as per the manual.Any ideas would be much appreciated.

Is that 4.6% to 6.4% per color? On an average of 5.5% per color that's 22% fill.

The quoted yield is based on total 5% fill. Based on the numbers you've quoted that's ~20% cartridge yield. It doesn't take too many 100% fill copies to drive up that usage. To get the 5% to show 100% cartridge yield you would have to show 1.25% per color on average.

Take my word on this, nobody does 5% fill copies/prints.

Are you using the numbers off of the service status page? if so, you need to be aware that they are only the readings of the last page produced (the page produced before the status page you would be getting the numbers from).

Toner usage

I have taken the relevant information from the toner coverage reports.
The copier has completed 123033 mono copies and 77034 colour copies using a total of 25 Black toners and a total of 33 color toners.This is a government customer so that the CPC is fixed and we are not allowed to charge for any excess toner usage.Colour toner as per the report is averaging at 5.5% per color and black is averaging 4.29%.Bearing in mind that each toner is rated at 20,000 copies @ 5% coverage. That's if my maths are correct, only 8002 copies per black toner.

That's funny, my math came out just like yours...... I don't know.

Do they run a ton of duplex and is the machine not set to double count duplex?

Are they selling the stuff on eBay???

process black perhaps?

[expom]

I have no idea what you mean?

[blackcat4866]

Process black:

Process black is black image that is formed using the four colors (CMYK). The problem with this theory is that black copies made in full color mode count as color copies, and should accurately track usage.

Toner problem

Check with your kyocera rep
two months ago they wanted toner yield data

[kissy]

It all depends upon the density ,photographs,full and richness of the original.Normally average 6% toner consumption is assumed on average normal text/photo originals.But it do changes with the types of original and the fullness of the matter.
It is experianced at the Government sector,they have fully filled formate type of originals at the most.Definately it will be consuming more toner.Another thing is the yield per toner cartridges which is claimed by the agents are not 100% true.You have to take it granted for 10% less than what they had written in the manuel.Because thats as they write is based on the standard working conditions.
Well you may try on toner save mode and check whether it gives some different result ,otherwise change the developer and do the caliberation and adjustment programming.

Toner Problem

I have checked with our Kyocera State office who assures me that all their machines are getting the correct yield!!

[bsm2]

toner yields

yields are based on running THE SAME 5% ORIGNAL 15,000 times
I don't think your customer or any customer does that.
Still have not supplied us with the model in question.
Contact your kyocera rep and dissuss the issue with them, supply all data you have status pages, toner pages etc......

Model is a KM-C2630D.As previously stated,the machine is only doing 8000 copies per black toner. I accept that it is rare to get the full yield from a toner but under half is excessive.
