Sharp copier Mx 5000N is doing continuous toner replenishment I changed toner cartridge drum developer still replenishment what do I do

If the cartridge is damaged, replace it with a new one. Clean the contacts on the toner cartridge and in the toner cartridge compartment with a soft cloth.

Detail:

ATC sensor value abnormality

Cause:

Connector connection trouble
Toner cartridge installation trouble
Sensor breakdown

Check and remedy:

Connect the connector again.
Install the developing unit again.
Replace the developing unit with a normal one.


Thats what the Manual says, your toner is not replenishing , could be your toner motor , or your toner is empty , or your developer sensor

F2-40 = ATC sensor abnormality ,
your toner is depleted , or is unable to replenish toner level in developer after X amount of time . a simple crop 14 should clear the error , but if it persists then you have bigger issues , try to check developer unit gears if they still function as they should, and check your toner level, and check your toner motor,

and if all is said and done try another toner cartridge, but be aware that the F2-40 usually fries the chip on the toner cartridge (not always though)

You need to take it to a Sharp technician to check machine , usually a toner issue that toner is unable to replenish in developer unit and so blows the chip on toner cartridge ,

replacing toner cartridge rarely helps
seeing as it is a deeper issue

Problem with your toner supply .... you're not getting enough toner mixed into your developer tank. Sometimes the cartridge will empty out without the machine giving warning, or the CRUM counter chip on the back of the cartridge wil zap out or wind down to zero. Try replacing your toner cartridge, if that doesn't clear the code your developer mix is out of balance and may need to be changed and reset.

It's not developer light.
It is drum unit light and maintenance.
You have to replace the Drum, Blade and Developer.
After changing them you have to reset the maintenance, drum,developer counter.
This procedure must be made by a copier tech.

But if you still want only the developer the code is AR-202D

what brand do you use?because No-OEM toner cartridge may be not suit for the Drum Unit? change a OEm toner cartridge to test again.maybe solve this problem.

on this code you may have to clean out the developing unit and start with fresh developer. Make sure the developer unit is not leaking from one of the bearings. You may need a tech for this one...

The cleaning blade is in the drum cartridge.
There is no developrer change in that product.
There are 2 cartridges.
The toner and drum.
Toner contains all you need as far as ink. And also the waste sump is on the toner cartridge.
The Drum is a self containted unit that has the cleaning blade and auger built in.

That unit uses an AR-016TD Toner/Developer Cartridge. The developer is changed each time you replace the toner. To remove the drum unit open the right side cover, then the front cover, remove the TD cartridge, loosen the green screw on the front of the developer unit housing just above the TD slot. carefully remove the DV unit without tipping or you will spill out the existing DV. Then you can pull out the drum unit. There may be a green screw on the drum that must be loosened but I don't think so on that particular model. Installation is the reverse of removal.
