Question about Sharp Mx-4501n mx4501n
I have a Sharp MX4501N copier/printer and wish o determine how much of the toner cartridges have been used up.
Hold down the copy button. These are approximate values and are calculated so they are not right on.

SOURCE: leaking toner
Make absolutely sure you are using new OEM Sharp supplies for this machine. I sell OEM and generic, and I always have trouble with generics leaking in Sharp copiers. Also if the drum unit has toner backed up in the waste channel, it will leak out.

SOURCE: Dirty Background on Printouts
The most likely problem is not with the drum unit but rather with the developer unit and there is a leakage current within the unit causing the 'ghosting' on the printed images.
I would suggest that you replace the developer unit within the system. It is quite possible that the waste toner blade is contaminated with debris from using non-OEM toner within the unit. Therefore leaving residual toner particles on the surface of the drum.
Try this solution and see if that corrects your problem. This solution can be applied to virtually any laser printer, copier or MFP device in the industry. The problem is nearly 99% of the time related to CHEAP toner cartridges that are refilled or refurbished and the company doing the work does NOT replace the cleaning blades within the units, and they use a generic polyester-resin toner that does not conform to manufacturer standards.
I worked as a Design Engineer for Kyocera-Mita America for nearly 6 years and have seen this problem many times in the industry. The price you save on using recycled cartridges ends up costing you more when you have to replace a developer or drum unit.
Hope this information helps you out.

the problem in your machine is on the drum unit there is a arching on the mc unit.located in the upper portion of the drum unit.if you have an old drum unit try to install it again just for testing.and check if ther is a dumping toner again.

the DK message means it is time to replace the black drum unit. the drum unit is called an ARC26DU. open the front cover. remove the toner cartridge/s by lifting the green
lever and pulling the toner out. Open the left side door. look at where
you just pulled out the toner and there is one screw (facing you)
holding each drum in place - loosen the screw and pull the drum unit out
towards you....slide in the new drum unit.
to reset drum counter go into SIM mode by pressing the following keys one after the other "P" "*" "C" "*" then 24 and start/copy key then 7 then select the color drum you are replacing and confirm reset. make sure copier restarts afterwards
DO NOT refill these toner cartridges (even if you can find someone to do it) The toner cartridges for these machines have generally had ongoing problems as far as longevity and quality - refilling them will only make it worse.

Open up the large front door, it will swing downwards. At the top section you'll see four boxes with front handles. Each of the boxes is a slide-out container of toner.
Follow the instructions on the new toner box to prepare it for the copier.
You'll note each toner box has a color designation (on a plastic label just above where you grab). Simply grab the handle on the one you need to replace, pull it out and then slide in a new one.
Also note there are four colors: Yellow, Magenta, Cyan and Black. The LCD screen should indicate which toner bottle(s) to replace.
