the -: impressions must be in "Text & Photo" mode and not "Text" if not for jobs / features to make photocopies should always use the "color copy" button except for jobs / traits, it is can not use these cartridges with any other Epson cartridges (just remove the Epson)
Despite - you soon get used to it and the quality is at the rendezvous, and for the price (almost 6x cheaper than the original) there is nothing to say. Level quality / price I put 5/5 compared to the Epson I estimated 3/5.
