TA 2552ci has C7001 error

[Samanator]

We brought this machine in because the professionally challenging customer was tired of the clicking noise the machine was making. They instead of us bringing out a loaner while we solved the problem with the machine. So, when the machine arrived, I removed the back so it would be easier to find the clicking noise. After removing the back, I switched the machine on and it went right to c7001.

I took the drive unit out and put the vac on the waste toner areas. I have had the Toner Supply Drive Unit out and vacuumed it out till I got it as clean as I could. Put it all back together and still C7001.
Kyocera support hasn’t too much help. They have only suggested doing what I have already done.

Not sure what I’m missing here. Any help would be great.

And as always, thanks in advance.

These do have waste toner problems there are a couple of technical bulletins best to replace waste assy they have removed a sensor on the new units also you get a clicking noise from the main drive assy also the transfer cleaning unit

C7001 refers to a toner container locked up and not rotating. It shouldn't have anything having to do with the waste toner system.

If you are able to, run U030 container mix motor, you might hear the clicking noise.

There is a bulletin relating to the cartridge drive, I will post it if I can find it. You may even have a problem one of toner cartridges.

Thanks guys.

Kinda hard to run U030 when the machine has already C7001.

I thought in some cases you could run maintenance modes when there is a c code. It would help you track down the noise.

Here's a couple of bulletins relating to clicking noises.

KM-5052ci, "Add Black Toner" when images are over 5% fill

Maybe something like this? =^..^=

I bet your waste bottle isn't turning. Vacuum the waste channel under the main drive, vacuum out the transfer unit or replace and replace the waste assy.

use a magnet to trigger and remove the toner container solenoid connection cover(black cover to the right of the black toner). reach inside there and operate the toner door lever which will open all the doors.
press the main front cover button to simulate the door being closed, power-on the machine and observe the containers rotating. Maybe you'll see one that doesn't turn and can investigate the drive system accordingly.

Turn machine off, unplug. Allow all capacitors to bleed down. Open front door, plug in, turn on and start entering service code until it enters service mode. Close front door and run maintenance modes.
