I replaced the toner cartridge chip for my sharp copier AR 6020 and the error code f2-70 appears. How can I clear the error code.

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 F2-04 error code you are getting is that you are using the wrong toner.It may be form sharp,but it toner chips is different.Only the chips swapping at the toner back can help you.

Clearing a trouble code on a AR-M160 is a little different than the AR160.

Try "#" "interrupt" "clear" "interupt" "1" "4" "start key"

This should clear the error. Even if you replace the fusion unit you will need this code to clear the error

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.
