The readout is CH. The door are shut . Nothing

if CH blanks , your developer unit not inserted.
no blanks mean that side door or front door is open

Sharp AR-M550 with a paper tray error F3-12

1. Start and end of simulations Note: The "PAUSE" key in the descriptions means the "INTERRUPT" key. Simulation IN The Simulation IN mode becomes only available from the Copy mode screen. In the simulation mode, printer operation is inhibited. Printer operation is also inhibited in either of the Aging mode or the Adjustment Copy mode. The printer selection key is disabled, too. By operating the keys [C] – [PAUSE] – 0/g – [PAUSE], the simulation main code input screen appears. * If the interval between any two key operations is more than 5 seconds, the entry into the simulation mode is canceled. (Ref.) 1 ~ 9: Loading/ sensor checks 10 ~ 19: Resetting troubles 20 ~ 29: Counter/mode setting 30 ~ 39: Sensor activation checks 40 ~ 59: Adjustments 60 ~ 69: Digital readout and printer Simulation OUT The simulation can be terminated by pressing the [CA] key. 2. Simulation main code input screen SIMULATION NO. _ INPUT MAIN NO. AND PRESS PRINT SWITCH 1 If any trouble has occurred when the trouble code is requested, the 7-segment readout displays the trouble code (main only). [Note] The trouble code is canceled when the copier enters the simulation IN mode. [Note] The 7-segment readout becomes blank when the copier enters the simulation IN mode. 2 Only the [PRINT] key LED comes on. [Note] The [PRINT] key LED is usually OFF. It comes on when the copier waits for the [PRINT] key to be turned ON in the simulation mode. 3 The main code input area (2 digits) waits for the input of a main code. [Numeric Key]: Main code input [Note] Codes are entered in the ring format. [PRINT]: Sets entered data. [C]: Clears entered data. [CA]: Terminates simulation. [Others]: Cancels (ignores) entered data. 4 If a simulation has a sub code, it should be executed on the sub code input screen; a simulation does not have a sub code, it should be executed on the simulation execution screen. 3. Simulation sub code input screen

Sharp AR-160 has an error code CH when you power it on

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

I believe that that "CH" code means that one of the doors is not fully closed. Not sure because I haven't worked on a Sharp in a couple of years. It's easy enough to check though. Let me know if that helped.
