At work I have a Espon Stylus C86 which has been working up until now. I ran out of my colored ink, so I changed all the colored cartridges at once. I've done this about three times in the past months and no problems but now after I change the cartridges the printer recognizes the new ink but it wont print in color!! I have tried everything - cleaning the print heads, checking the nozzle, going through all the steps and nothing works!! Epson was no help they basically told me to do the very exact things I already done. So, can anyone help me?? Thank you!!
