For essential:
I just need to change cartridges 3 and YES in the first two rounds of ammunition I have messed up my fingers, but always put a certain learning process behind it. If you do not like a gas sick on the plastic wrap around the cartridge fumbles and compresses, so that the color does not splashing out, you can change a cartridge, without spilling a drop of color! Therefore you have to solve only the tab and slide natured in the other direction while the cap is off almost by itself !!
Conclusion:
Print quality is OK for me fully, but have to say that I have no glossy photos or equivalent Prints, as I leave the review previous speakers. Cartridges are recognized until now also displayed the correct level and so, for the price absolute recommendation!
