Maintenance required: code dk - Sharp MX-2300N Color Copier

The code refers to the black drum reaching the end of its life. Sometimes you will also have a VK code that is displayed along with the DK code. This refers to the black developer life. Both drum & developer have a life of 100,000 copies which is why you tend to get both codes at the same time. The maintenance code should still allow the copier to photocopy & scan as normal, so if the copy quality is still OK then the machine should continue as usual & the codes are reset when the drum & developer are replaced.
If you have a problem printing to the copier from a PC when the maintenance codes are displayed then this can be rectified 2 ways. The 1st way is to have the parts replaced & the counters reset. The 2nd way is to turn off SNMP setting within the printer driver. If you open printers & devices & locate your printer. Right click on the printer & scroll down to printer properties half way down the list (not the properties at the bottom of the list). The third tab along the top should be Ports. Click this tab & this will show the port details of your printer. Click on configure port & this will open another box. At the bottom of the box to the left there is a tick box with SMNP enable. If the box has a tick in it, untick the box, click apply then close all the open windows. This allows the printer to print when the machine displays maintenance codes.
Hope this helps.

black drum needs replaced

DK refers to the counter for the black developer powder.... a service call will be needed for this

DK means the black drum has reached its maintenance life - 50k copies. you need to buy an ARC26DU drum unit. The drum counter will need to be reset after its installed.

Hope that helps.

"dk" means the the life black drum is over. You need to replaced the drum and blade. Or you can replaced the whole drum cartridge. The line that you are getting from one of the blades, more likely from the black drum. Pull out all the drum check if there is toner on the drums.
