Re: 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

My ricoh aficio code a 990 how to fix them ?

An SC990 is usually an error indicating maintenance is overdue. The only way to verify that is by printing out the SMC report and seeing the subcodes. In the case of this model when is the last time the drum and developer was replaced?

How to solve this problem sc 302

I managed to find a list of Ricoh error codes with brief explanations of their causes here:
Ricoh copiers error code messages

This clearly identifies the problem as a laser motor problem - OR
Charge roller, HVT, or fuse FU5 (AFICIO 340, 350 series, 355, 450 series, and 455) - OR
SC-302-01, 02, 03, 04 Charge corona assembly Aficio 550/650
SC-303 Charge corona wire cleaner, disconnected or time out for printer.
All of these sound rather like an engineer requirement but you may be able to something with appropriate spares

SC326 is a laser synch detect error. The jamming is probably just because of the code popping up and the machine shutting down. 9 times out of 10 the cause of an SC326 is toner dust buildup on the laser optics. It is either that or possibly a laser unit (LD Unit) failure. The power to the LD unit flows thru the front door switches and I have seen those go bad and cut or reduce power to the LD unit which will cause the same code. I would get a Ricoh tech out to clean the laser optics. This is especially true if you open the fron door and there is toner dusting around the toner cartridge/DV unit area.
Good Luck and Thank You for using Fixya.

Open heat error

From looking at the manual it looks as if you have a faulty thermistor. When warming up, it has to heat up to at least 60 degrees. If it stays lower then 60 degrees celsius for over 35 seconds and doesn't reach 60 within that time frame then that would cause the open heat error that is happening on your machine.

Ricoh 1515

Turning the main power switch off and on, resets the SC code if the error is caused by incorrect sensor detection.
If the error is still there, the laser synchronising detector or laser diode is faulty. Please call a service engineer.

Good luck and please rate me, thanks.
