Hi I Have a message saying colour pcu type A Flashing ? Ricoh Aficio AP3800c What do i need Thanks

This message indicates that the colour drum(s) (called pcus) have reached near the end of their counter life. If the output is still ok you can safely ignore the message for now. If the machine stops working, then you'll either have to replace them (expensive) or if the quality is still ok, then reset them. Take a look here.

I have a Ricoh AP3800c and need to get into Factory Mode to set the destination code. Service Mode lets me look at the destination but not change it. Can anyone tell me the procedure?

power off hold down the job reset and
the down arrow keys together and power on (whilst holding the keys)

The only time you should need to get in to PP Mode is to set the country code
Please take care when in this mode as you can change settings which are for Factory/Design
use only and this could affect the machine

Cause for error code sc560 on ricoh ap3850c

H there below is what is stated in the service manual and I suggest to change the power cord before the main PSU (Power Supply Unit)

SC 560 Zero Cross Error

When the power switch is turned on. The machine checks how many Zero-cross signals are generated during 500 ms. If the number of Zero-cross signals is more than 66 or less than 45 and the condition is detected more than 10 times this code is shown.

Cause is electrical noise in the supply from the power cord.
  • Change to another power wall socket
  • Change power cord
  • Replace main PSU (Power Supply Unit)
I hope this help you
Thanks J

Service Mode

The service mode for an AP3800c printer only is different from the copier version. push down the up and down arrows together for a count of 7. Then push the enter key (#). The screen should now show "engine" in the window. If you are resetting a function you will need to arrow down to "service" then push enter (#) again. Use the escape key to exit from the sub menus. To exit back out of SP mode you will need to select "end" at the top line menu pressing enter to accept.
