Clogged heads

I have not used my ep 1400 for many th . I have Inthrift inks. I installed fresh ink cartridges
rest the cartridges and everything reads ok.nozzle check shows no black. It is clogged. What do I need to unclog this. Do you have a set of filled flush cartridges for the 1400. If not would you begood enough to tell me what I need to buy

Hi inewton5~

I recommend you manually clean your printer’s capping station, wiper blade and bottom of the print head, and you may need to flush the black print head channel with PiezoFlush using our print head cleaning kit. Instructions (and videos) are available here:
