If it is on solid then you have a cover that is not closed try opening and closing all your covers. sometimes you need to use tape to hold them down if they wont stay closed on their own. If it is blinking then your developer unit is not communicating with the machine, this is the unit between the toner and the drum that is normally held in by one blue screw. pull it out and try using canned air to clean the electrical contacts on the back of it.

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.
