SOURCE: my sharp ar-5316e error code CH please help me

Hope you are fine, ch are in two forms steady one and the blinking ch.
Steady CH
This is associated with door switch for either front cover or side cover. Check that the front cover of the copier and the right side is well closed.
Blinking CH
This is associated with the toner cartridge or the developer unit not being sensed by the machine. Make sure that the developer unit is well locked in the machine. Pull out the toner cartridge and insert back with some force into the machine, it should clear this sign. If it does not, replace a new cartridge Sharp Ar016ft and you are done. Good luck.
