Even if the acquisition of the printer scanner combo device Epson WF-2540 just under 80 Euros was still favorable with at the time, this price into perspective in the rather expensive cartridges. Currently 9.90 for small cartridge with just 5.4 ml / only about 175 kinds of leaf print (!) Or even 17.90 for the XL cartridge with only 12.9 mL / only 500 possible sheet printing (! ) is but a bit much. Consider - for a few times cartridge purchase the XL version you get again a new printer cartridges including Epson. Therefore, the cartridge prices have kept consumer-friendly in any way, serve rather to profit optimization for the Epson Group, since the manufacturing cost of such a cartridge are only minimally, is thus calculated with a high charge here for the end user. 7,99 for small and 12.99 for the large cartridges variant which would for example. Just an unauthorized consumer-friendly price level. No wonder that many consumers are trying to cheaper cartridges variants dodge. But precisely where the so-called "Oops" is -. Epson has also made provision here, so that very few no-name cartridges can actually be used properly and you have more trouble with the non-original cartridges (eg conscious Failure to recognize the no-name cartridge by Epson devices scan or leakage of no-name cartridge up to the technical defect in the device thereby!). There are a total of me finally also an authorized rate of two stars for both cartridge types.
