New Kyocera FS-1135MFP, on power up it says "Developer unit not installed"'. Reinstall of all units and install of new units from maintenance kit don't make any difference. Any help?
Make sure the shield on the drum unit is raising up when the developer is inserted. It may stay down and keep the developer from making contact.

Hi Did you run up the developer unit? Menu button down to Other then to Service and press enter on developer and switch off and turn on will run for a while. In the service menu after you run up the dev unit you may have a option in there to press enter on the MK Symbol.
Cheers

For the message to be cleared you should enter the service menu and reset the replaced elements

Hi not sure if you tried this...
It can also be that your toner cartridge is empty
Try inserting a new toner
I get this a lot with toner cartridge being empty on 1135/3514
