Seem to be seeing this alot more lately with people not using the machines for months any ideas what causes it?
If I do a Dev / Drum refresh a couple of times it goes a lot better then gradually goes back to white bands. I'm guessing it's the developer unit gone bad.Screenshot_20210225-231053_Teams.jpg
Black and Magenta are like that cyan and yellow seem to be fine. Any ideas?
Thanks for any help.
Yes, that's developer.
On the Saturns we had a way of making the machine self-calibrate more often. Naturally it used more toner and filled the waste box faster, but the more frequent stirring of the color developers did prevent the developer from dying slowly.
I can try to track down those settings... no guarantee that they apply to the AlphardII Series.
Maybe one of the other Kyocera guys has these settings for the Alphards? =^..^=
If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

I'm curious what causes the problem, too. Not that it really matters because we can't take the DV apart and do anything about it. Still, it looks like the DV is starving for toner or the doc. blade is screwed up 6 ways from Sunday. How man pages are on the DV unit?
I wanted to get some more practice today changing out DV's and drums on the 3551ci.
I changed out the cyan and magenta drum and DV. I timed it. It took 15 minutes to change the parts and put the machine back together. It took an additional 30 minutes to run all the sims and test. Total time: 45 minutes.
I've been using Work Flow but I never realized quite how valuable it is. The person who wrote the Work Flow Program (I don't know if he wants me to say his name) added a few extra steps when running the sims. Things like checking the DR & DV counts, cleaning the laser, ect. It's really nice for me because I always have to look at the manual because I don't have all the sims memorized that I need to run and there's no way I can forget a simulation when I replace something.
Also, I noticed that when I replace a DR or DV with a used one that the machine knows how many copies are on it. I suppose the DR and DV has an EPROM on them?
That's correct.
Many toner cartridges do that also, continually writing data to the EEPROM with toner yield data.
I'm not sure how much of this applies to the Alphard's ... but this is the changes we did on Saturns with this issue:
1) Set sim 464, Set Custom, set to On. 2) System Menu, Adjustment/ Maintenance, Color Calibration Cycle, select Custom. 3) Sim 464, "SetCalibTiming duringPrint", set to +480. 4) Sim 147, Set Operation Mode, select Mode 2. 5) Sim 464, run AC Calibration.
Please let me know if you figure it out. =^..^=

The ones I've seen do it are no where near life like 200k copies maybe 3 year old machines. They all use genuine toners as well.
What does a Dev refresh do btw since that seems to bring them back sometimes. I was at a 8052 yesterday and the copies where very pale did a Dev refresh and work flow 464 etc and back to perfect. Just want to try and understand what's happening so I can fix it better? Just doing the refresh made it go back to normal but I thought I'd do 464 etc just out of procedure. Does Dev refresh run a certain U code?
It's just a developer stir without storing a new value, or perhaps you'd call it a forced toner add. It stirs the developer until the toner sensor reads what it should.
Take care how many consecutive times you run the developer stir. Two times is ok. 3 to 4 times will cause overtoning. =^..^=

I got this from Luther a while back, and have used it with success for the AlphardII series:
From System Menu set Calibration to "short". Set U325 to "On" and Mode 2. Set U148 drum refresh set to mode 3. Set U147 set minimum to 20. There is an increase in waste toner usage, due to more frequent self-calibration.
I just came across it in the database. =^..^=

Just so I'm clear....
This will solve under-toning problems?
