Konica c284 toner problem

[lucycopy]

good morning,
I have a problem with a konica c284 I changed the toner BK and the copier remains to do the upload until you tell me that the toner is used up.
I tried to change DV but the same thing.
what may it have ever happened to you?

Hi,
there is a turning mechanism on the bottle, it is driven by the hopper unit on the inside/backside. Check if the bottle is being turned by the hopper unit by making a mark on the bottle wheel that turns.

Re: Konica c284 toner problem

There is one gear in the subhopper unit that drives loose, so toner is not transported.

Happens when the grid arch to the drum. It will empty the entire bottle into the tank with utter disregard for the TCR value and with no error code!. Replace with a original dev tank and drum unit at the same time.
Don't ask me why that is but had this a couple of times and only on black.
Could also be be the relay board infront.

Sure you don't get an error code?

This happens a lot with aftermarket toners & developer.

On startup you will get TCR at 0% if you get 0% and the colors have a value you could have a different problem.

Re: Konica c284 toner problem

It is not uncommon to have these white bushings/seals on the hopper pack with toner and stall the toner drive. If you remove the engine cove and watch the bottle drive you can see the affected color chatter and vibrate but not rotate. It's better to remove the hopper. Remove the front bushing and vacuum out the first hopper and clean the impacted toner from the bushing. Remember there is a rubber seal in there, don't damage it. Re-assemble first hopper. Repeat x3:

It is unnecessary to refill the hopper. It will refill itself in about 3 seconds. You can watch depleted developer tone back up in less than 1 minute. =^..^=
