I have got this machine up & running now, I swapped the complete hopper ass'y (all for colours) & the PRCB from an working C552, when I powered up the machine I could hear the K toner motor run & I watched the K toner % reading go back to normal.
I ordered a new PRCB for the machine I took it from but it was different, it had some connections missing! see pictures below.
I ordered
A2WUH00101 (got from the parts manual)
But the part number on the failed board was
A0P0H00100
Both parts number are definitely correct & both for the C552, but why does one not fit! Aggghh??
