664-01 code

[Tefao]

Greetings. please i need in clearing SC 664-01 on Ricoh MP5503. the machine literally comes on but that's just all, no noise from any moving block or roller from inside. with this code on the display board, no other function or operation can be carried out.

It is covered in the service manual.

As per manual ....Description:ASIC on the IOB SRAM program expansion error. Access permission error to ASIC on the IOB SRAM (write permission fails)

Causes: • Noise • Hardware problem

Remedy: • Replace the imaging IOB and paper transport IOB • Check the harness....

(let's not confuse we are talking about MP C 5503) First of all a toner chip could also be faulty, clean the chip reader as well.

You can turn off the machine completely, wait for a few minutes, and then turn it back on. Sometimes a simple restart can resolve temporary glitches.
