    hi jaylet

    thank for the solution provided for my ricoh ap8550C printer. it really works. the problem as you rightly put it was the wall power socket. the contacts in the socket was loss( poor contact), so the result was sparks each time the printer is trying to start up.

    you gays are really the gurus that you are call.

    thanks a million.

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.
Solution

  • 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?

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.
