Code changed from e020-0489 to e025-0451. Dens-K is at -3.20. Machine has 332k total and 179k black copies on it. Copies look good (only makes 1 copy, then codes).
Customer had been running 100-150 full coverage 12x18 2 sided that was mostly black. Seems like the black hopper toner replenishment couldn't keep up with usage. I didn't see a way to add toner or, prime the hopper or fill the dev assm like on older machines.
I checked the dev atr connector and all associated connections. Removed and inspected the K dev assm and looked at the K hopper (didn't remove). I didn't see anything that was binding, bad gears or not moving/connected properly.
I'm planning on going back with a K dev assm. I'd rather not have to replace the K hopper if it's not necessary, I've done them before in the c52xx machines and it's a PIA.
Anyone know of any tech pubs or common issues with this? Other suggestions?
