I have a customer with 4 AltaLink C8155's, and he repeatedly has problems with the black toner. Every now and then, when he replaces the black toner cartridges, within 100 or so pages it will deplete the developer, and the prints will be very light grey. Replacing the developer (material) solves the issue... for another 100 pages or so. The only thing that works is replacing the black toner and the developer material, and it will run fine. Until there is another unlucky replacement of black toner.
Since all 4 machines have the same issue, and since the problem is always resolved by replacing the toner and developer material, the toner is the obvious suspect. The toners are all original from Xerox, no refill. Some of them are metered toners, which have been fitted with a sold chip. But I don't think that is the problem: the color toners also often have 3rd party sold chips installed and work just fine. Also, the toner chip shouldn't have any influence on this particular problem.
Has anyone ever seen a similar problem, or are there any reports of bad toner batches in searchlite (I don't have access to searchlite)?

in my experience, chip does not deplete developer material. chip is like a traffic light... red means stop printing, green means you can print... Yellow = please reorder toner/drum.
If you are using original toner, then I suspect the problem is in developer assembly unit.
try replacing it whole unit (new)
if you have spare time.
try opening the used developer assembly unit,
1. open the plastic mylar seal (push right to remove)
2. Under the developing roll/magnetic roll there is a metal sheet acting like a blade.
3. try adjusting the distance between developing roll and metal sheet (2 screws on left and right).
4. this needs a few times to do (trial and error).
Thanks for the tip. In fact I have changed the developer housings on 3 of the machines, but this does not make a difference. I'm hesitant to adjust the developer housing. I'm just hoping I had a bad batch of toner, and the worst is behind me. But I was hoping to get some confirmation on that.
