Sharp MX-2300N Maintenance Required: Code VC - Sharp MX-2300N Color Copier

The firmware is only available from a dealer. You can make an arrangement to get it on a USB thumb drive and update the machine using SIM 49

Derp 101: Please state your category of problem. Misfeed, Error Code, Maintenance Required Code, Can't Print, Won't Scan, Lines on Copies or Prints, Bad Print Quality, etc, etc,

The VC code on a sharp mx-2700 is the cyan developer has reached its maintenance cycle of 60,000 copies. to clear this code enter sim mode #, *, C, * then 24-5 to clear dv count.

The TA code refers to the maintenance cycle of the copier. Its the copiers way of saying ''come and see if im ok''. I would recommend resetting the maintenance counters for your drums, developer, fuser and transfer belts. This can be done in the engineers menus.

It means that your fuser unit has reached its lifespan: you can still use the machine but be aware you will need a fuser rebuild in the near future

Ok so the DK code means that the Black drum counter has reached its limit
To clear this you need to clear this easy you want
# , * , c , *
To enter service mode
Type in code 24 press start
Then you want sub code 07
Then you can select what you want to clear so the bk drum unit
Execute this yes then press the CA key the machine will restart and away you go
I also do advise that you service representative comes along at some point to check the machine it could need parts because if you stretch the life of parts your machine could become unreliable... But that is up to you.

enter code 20 start 1 start

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.

reset it by simulation no 24 n then ul get t detail
