Does this appear to be a clogged Damper, and if so, would loading a Cart of Piezo flush on the PK channel potentially fix it? Five of the other Epson inks are very low, so I am considering purchasing a new Epson P800 instead of dumping more $ into R3000. Went back to PK black, still no black channel on nozzle check.

Switched to Matte Black, still no black channel on nozzle check.
#Ink supply unit for epson stylus photo r3000 manual
Nozzle checks revealed a completely non-existent black channel - even after numerous print head cleanings and another manual external print head cleaning with Piezo Flush. Installed a NEW Epson PK cart, because the previous one emptied after all the head cleanings! Noticed that all print head cleanings after these 3 steps, produced an ink foam coming from the external waste tank. Installed an external waste tank (not from ink jet mall) and then Cleaned Print Head and docking station, and wiper blade with Piezo Flush and bounty towels and foam sticks per the inkjet mall video. There is a possibility that the only differences between a P600/P800/R3000/3800/3880 ink supply assembly is the ink cartridge holder as it is obvious that it needs to fit the smaller and larger carts. Printed a photo and the black wet streaks immediately returned. I have no idea if the P600 components are the same as the 3800.

I purchased a R3000 in November of 2011 and have not used it very much (only on 2nd Carts of Epson inks)! 99.9% of use was with PK, not MK.
