Maintenance code vk - Sharp MX-2300N Color Copier

black developer need to be changed

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.

This is one of the scheduled maintenance codes. it comes on at a certain "milage" and requires a technician to reset it.

If you're in Houston we'd be happy to help you out, and supply new machines should you need any.

TA is like the universal maintenance counter, on this model only one code is displayed at a time. hold the copy key to figure out how many copies have been made on your machine and then call your
Sharp dealer they can tell you what is do to be replaced.

I have the book but I cant find the codes.

So find out if your rad fan is coming on. If it does then pull out your thermostat and place it in a pot of water and see at what temp it opens at. The open temp should be stamped on the thermostat.

If it is stuck closed or opening to slow, replace stat.

Good luck!

Check out this little walkthrough I have put together. Adjusting the printer port settings on your computer should take care of it. Sharp Printer Offline Solution

VK means black developer has reached end of life. You can safly carry on using the copier with this message displayed but over time the copy quality may slowly degrade. You will need to call a Sharp authorized dealer to replace the developer in the developer unit.

VK = 100,000 pages printed on the developer counter or 715,000 revolutions of the developer unit (as mixing can occur even when pages are not being printed). Developer can break down over time and or the seals can be damaged - so service by a technician is indicated. If maintenance was recently performed and the developer replaced then the counter needs to be reset.
