Hi, I have not used my DCP-135c for about 1 month as I never got round to getting more ink, I have just got new ink and have installed it, the Cyan, yellow and magenta are all ok but the black will not print. I am suspecting the print head has dried/clogged ink in/on it, I have had a google and inspected the printer but cant seem to figure out how to open the thing. If anyone has any experience with these any info would be very much appreciated. Thanks,
0put flush liquid in an old ink tank and run that through it might clear it. the print heads are not removable
