The MFP is now fully functional, but the blue and yellow cartridges need replacing. I refilled the blue one with a little ink, but because of that damn chip, which can only be reset with a special programmer (available at the service center), it won't print. I'll have to buy a PZK system with resettable chips from Anechka here: http://www.originalam.net/cart_orig/ For those who want to help develop the channel:
