How do i fix an error 10 CH

Try to turn off the email scanning of your Antivirus.
You may have to change the email server information over to the one that is in Belgium. Looks like your computer is still trying to use the one from Schweiz.

Hi olixrules

CH light blinking - The DV tank is not installed.

CH light steady - Door switch is not turned on (interlock switch is ON).

Hope this gives you some idea, unfortunately I'm not sure how to resolve these error on this particular copier.

CH - open cover in the paper feed area
CH blinking - Dev unit is not properly installed
For the 'CH' check the covers and make sure all covers are closed properly.
For the 'Blinking CH' take the dev. Unit open and the reinstall unit properly.
Pls rate – thank you

Actually that means your out of ink. Odd code, but that is what is means.
