I have now purchased 3 printer & CISS bundles from City Ink Express, 2 Brother printers and one Epson. They have all been straightforward to set up, one of the Brothers came with ink in the CISS system, all I had to do was fit the air filters and slot the cartridges in. The second brother I had to fill the ink and then prime the cartridges but this was easy with the aid of the video on the City Ink Express Youtube channel – I would recommend you watch the relevant video before setting up your printer. Both the Brothers have a separate ink tank, but it doesn’t take up much space.
The last printer was an Epson with refillable cartridges which I haven’t done yet, but it’s just a case of filling them using the syringes supplied and removing the air plugs. This a great option if you don’t want a separate tank with tubes.
