I am a big fan of brother printers and have used them for years. A few years ago Brother printers used to have chip-less ink cartridges which are DRM free cartridges making them easy to refill or replace with re-manufactured ink cartridges.
The new Brother printer which now have the chip can still be converted to CISS printers. In fact they make great CISS printers due to their design.
If your interested in trying out a Brother printer and using it as an CISS printer I recommend getting a MFC-J870DW which is one of the best and most reliable printers in the Brother fleet of ink jet printers.
The J870DW is a really fast all in one printer. It has a fax, scanner, copier and printer in one package. The print speed is at par and even slightly faster than Epson and HP. The added wireless functionality makes it easy to print using your Android or iOS devices.
I went through the best options on converting MFC-J870DW in to a CISS printer. Bellow are some of the best kits you can use to make it one of the best CISS printers.
The refillable ink cartridges comes with an easy manual on how to install it on your Brother printer. You actually just need to remove the normal cartridge and insert the CISS Cartridges. You will then need to remove the flap cover and insert the ink cartridge flap sensor.
