Bizhub C224e Constantly asking for Magenta toner

[photocopier.technician]

Hello,
I am having a problem with a Bizhub C224e, it constantly asks for Magenta toner. I already replaced with a new toner but still same problem.When i put the new toner it says replenishing toner and after a few minutes it asks for toner.

Replaced the developing unit still not working.

Thanks for help

Can't remember if thesw toner bottles are chipped. If it is, it could be a bent pin on the body of the machine. Straighten the pin and it will work just fine.

How many copies on the machine? If the toner bottle is not chipped, it could be that the toner hopper is clogged, that will need to be removed and cleaned out. But usually it will give a code for the tcr level (can't remember which code for magenta tcr, C-255*) if that's the case.

Thanks for reply.The toners are not chipped. No error C25XX. I will clean the hopper with a blower and keep you updated.

Not uncommon, on this series, to replace the sub-hopper unit. If the sub hopper does not have a white plug on the end facing out, you will want to replace it anyways.

Sounds like the sub hopper is not filling up or the actuater in the sub hopper is stuck.
Remove the cover over the toner bottles and check they are rotating when it is replenishing toner.
If not and the sub hopper is empty, then check the actuater has not come adrift. This can cause the bottle to not rotate because the machine thinks there is already enough toner present. If this is the case you will have to split the unit and refit the actuater. By the way if you decide to replace the hopper it's wise to check these actuater as I've had brand new units with stuck/loose actuater.

Hello,

Thanks for all the replies. I removed the sub-hopper unit and cleaned it with a blower. Tested on the machine did not work. Tested with another sub-hopper unit from a working machine still same problem.

Check both sub-hopper units there is toner in them, so i think the toner bottle motor cannot be suspected.

Both sub-hopper units has a white plugs on the end facing out.

blackcat i did not understand the indication with the 2 photos.please explain.



Thanks

Do you see the magenta toner packed in around the front seal? It's not supposed to look like that. It causes the shaft to bind, and stall. The motor cannot turn the agitator, and the toner is not fed down to the developing unit. If you watch with the engine cover off you can watch the drive shaft shudder, but not rotate. =^..^=

Hello,

Blackcat thank you for explanation, i checked the drive shaft shudder and it rotates so i think the problem is not with the hopper unit.

Any idea what can be the problem ?

Thanks

Had a faulty/bent harness causing the toner bottle drive not to turn every once in a while - so try and mark the bottle to see if it turns.

Hello

thanks for the reply GIFT. I checked the toner bottle its turning and also the hopper is full of toner. Replaced the Front side board and after that the printer control board. No success till now.

Any other idea ?

May be the agitating blades of the feed hopper

A quick test that I do is to put electrical tape over the developer inlet. Run the machine to trigger toner add. Check if there is toner piled on the tape. This tells you if toner is exiting the sub hopper.

hello friend...
did u ever found the cause if this particular problem?
I face the same problem on a bizhub 224e monochrome (black) machine and I still cannot find what is the cause of the problem.
l have tried everything suggested on this post for your problem but nothing work.
I didn't try yet to change the front circuit board or the printer (main controller) board as you did but I cannot take the risk to order and charge my customer boards just for testing purpose.
also, I suspect the sensor on hopper and is the last thing I will try next days because is cheap and possibly easy to find from another machine.
I would appreciate your answer on 2024 if you managed to resolve Ur problem back in 2017.

Would you list what you did?

This may surprise you, but sometimes posters lie, and say they did things, and then they didn't. What things did YOU do? =^..^=
