Delivery took place as usual from another on the day. The cartridges are expensive individually sealed in foil with dried granules and in addition in a cardboard sleeve. Immediately after the onset of the cyan cartridge I have started the machine and it ran without any problems high.
Immediately launched proofs showed no perceptible to me another print image than before with the original cartridge (which I have as Stiftung Warentest with all sorts of technical aids shades etc. studied course not such.). A comparison with the day before yesterday (still with original cartridge) crafted content same print showed no visible difference.
Compared to the prices of OKI This really appears here as a bargain.
In the next few days I'll have to replace Magenta and then nachberichten. I currently have no reason to doubt that this cartridge will not fit without problems.
SUPPLEMENTARY 02/20/2014: In the meantime I have to replace Magenta. Same result: No problems, no optical difference to the printout with the original cartridges.
