Hello,
I am encountering an issue with the Cyan toner consumption rate.
The normal yield for 1x Cyan toner is 28K pages (as with other color toner cartridges). I would approximate our printing/ copying use on a daily basis would account for about 5% of the total copies in the cartridge's life (in a single day). Which should be around 1400 pages a day and since the configurations and print runs are consistent, I'm looking at around 2 weeks or optimally 20 days of life before it is completely depleted.
I am stressing this due to our Cyan cartridge not lasting more than a single day of use or even a single HOUR.
The above are pictures of the Cyan toner cartridge holster/ tray, with the sensor in sight. Not sure if this would be significant but, just placing here.
I did however take some pictures of something that may be a symptom of the above stated. Please see below.
The above was collected from the waste toner box. Normally the emptied waste toner box contents would be greyish in color and dull; not a singular color as seen above. The Cyan color was in full display as collected toner waste. Below is a picture of the waste toner box before it was emptied.
There were no error codes shown throughout the use of the machine so, whenever we would run prints the Cyan toner would be siphoned unknowingly. We've never had an issue like this before. We've contacted tech assistance from our local Konica Minolta distributor but, they weren't able to conclusively determine what was wrong with the machine/ toner cartridge.
Mentions of a faulty developing unit/ faulty drum unit and TCR readings were given as presumptions. Please see below for the pictures and readings:
They also stated that the TCR reading for Cyan was abnormally low. The technician then proceeded to check the developing unit and added some toner dust from the TN328 cartridge into the developing unit to "stabilize" the levels. Ran a stabilizer and imaging process before testing again however, the toner depletion rate did not change.
In a recent test I ran a copy of a booklet (A3 sized) with the configuration seen in the video below. It used 1% of the toner supply within the cartridge by merely printing out 11 sheets of paper. It was reduced from 81% to 80% in just a minute, may seem insignificant but, that is not the standard consumption rate.
Technical advice would be greatly appreciated. I apologize as I have no other information to contextualize this i.e. Jam codes, error codes due to the fact that there weren't any. If require any other information, please let me know in your responses.
