First, the praise:. Fast delivery, quick response a few minutes after my message to the supplier Fa STARTeurope, (now we are already in the negative part) has my just newly purchased Epson XP 620 cartridges not recognized that and refuses to work. After several (but fast) mails back and forth at first (try ... now you are trying times ....) the message that they wanted to send me free cartridges a recent batch, shortly after the meek admission that the manufacturers have informed that "your brand new printer is not supported by the chip. Epson has since encryption again adjusted so that the chip needs to be updated. This will be in the near future. Of course, we'll refund the cartridges." A reputable provider clarifies such things already in their own interests ahead to save unnecessary costs and time. . However, the company launch to have your chance: I asked to let me know (and if necessary to supply) when the chip fix should have borne fruit. I am curious to see if that actually happens.
