C227 internal error

[jwai]

I'd start first by updating the firmware & then the function version.

When scanning/copying the HDD is being written to so you could have a failing HDD.

The printing is OK, copyscan through document feeder is ok, mainly occurred on copy/scan through original glass.

I updated the machine with GC2-W4 firmware and test a period, this month I visit and check the error call times, 9401 > FA17 > FC06.

Now I consider it may cause of IR unit, flat cable, MFPB or other else?
