Brother LC-123, LC-125 and LC-127 ink cartridges have a relatively simple design and are therefore ideal for refilling. Another advantage is that the chip of the cartridge can easily be reset with our Chipresetter. After resetting the cartridge, the printer shows you the correct fill level of the Brother LC-123, LC-125 and LC-127 and gives you security when printing. The following pages show different refill instructions. There are instructions for the filling with the Refilltool "BroLuer" and instructions for the filling without tool; on the one hand for original Brother cartridges and on the other hand for our empty cartridges (Fill IN™). We will also show you how to reset the chip of the cartridge to complete the filling process.
