I do not know anyone out there is searching for answers but I have the definitive solution. After hours of work on this printer and research online, I've concluded that the PK line is defective (I do not know where). I was not going to send my printer for service which costs $200 and change the print head for $400. Anyways here is the solution: Step1: I put my Photo Black Ink into the Matte Black Ink slot and Matt Black Ink into the Photo Black Ink (switched the two). Ofcourse, if you try that, you would realize there are some insert pattern on the ink tanks that do not allow you to place the wrong cartridge into the slot. So, I used a knife and cut the platic vertical pattern off from the side of the cartridges to allow the switch. Step2: On the printer, I used the onscreen control and switched selected ink to matte black (remember in reality that location now has my Photo Ink cartridge) Step 3: I inserted a Premium Photo Paper (Glossy) onto the printer Step 4: On the computer, I selected any photo, select Matte Print out (like Ultra Premium Matte Paper) with Matte ink, (This will use my PK cartridge that I have inserted in the Matte Slot) and press Print Step 5: Be amazed! No blobs, no issues. I have ran over 100 prints so far and no issues.
