Sc672 is a communication error between the controller board and some other component. Did you switch the machine off using the orange power switch on the lower left side, or just the power button on the operation panel?

With the power completely off and the machine unplugged, pull the controller board out by removing the two screws holding it in on the rear left side of the machine. (It should slide right out the side.) Check all of the connections on the board and make sure everything is sitting securely, then reinstall the controller board.

Worst case scenario, you might have a bad memory stick, bad controller board, or another bad circuit board, but more than likely there is a connector somewhere that just needs to be set securely. You can also remove the operation panel (two screws on the top of the panel and possibly two screws underneath it as well) and check the harness that connects the op panel board to the machine.

Ricoh 3800c call for service


On the screen where it says "Call for service," there should be an error code (starting with "SC" and ending with a 3-digit number). This code can tell you what is wrong with your machine -- what code is displayed?

Does turning the machine off (with the main, orange power switch) and then back on clear the error message?

I have a RICOH FT 4022 copier and it displays E 5 error code. It does not allow copying. I have checked the fuser unit and its ok. What could be the problem? Do I need a reset code to solve it and where do...


The E5 code is the fuser malfunction error.
E52 fusing lamp warm up error.Possible causes thermistor open,heater lamp open,thermofuse open.
E53 fusing lamp overheat.Thermistor in shortcircuit
E55 fusing thermistor open
When service call E5 conditions occur they cannot be cleared by turning OFF/ON the power switch.To reset turn ON the main switch,turn DIP switch 101-1 ON and OFF(the DIP switch is located in rear part under main supply board).,and turn the main switch OFF and ON.

Reset the error code e-5 on a ricoh ft4522


There is no need to use dip switches to reset this error code.Providing that the thermistors are good and they have been installed correctly,here the reset procedure that is done through operation panel: press "Clear Modes" botton,then 107,then press and hold the "Stop" key for 3-5 seconds until you see the screen has changed.After that you need to turn the main power swith off and back on.The error code should be reset at this point.If it comes back,you may have a bad fusing lamp or a bad connector.

I do not recognize either of these codes (187 or 387) as part of the Aficio 2015 error list.

If the code is displayed on the screen, physically TURN OFF the copier with the main switch (red switch), wait 10 seconds and turn it back on. If it's an erroneous error, this should reset the error code. NOTE: THE ERROR CODE MUST BE DISPLAYED FOR THIS TO WORK.
