Printer head cleaning cartridges for Brother, Canon, Epson and Ricoh. For unblocking nozzles on print heads, these cartridges contain cleaning fluid that breaks down stubborn blockages in printer nozzles.
Before using you will need to remove the colour air plugs or yellow tape from the top or side. This opens the vacuum inside the cartridge and allows the cleaning fluid to flow when printing. For the cartridges to be recognized by the printer it is sometimes necessary to install the complete set.
We advise that you target the colour nozzle that is blocked. For example if it is the cyan, then print pictures of blue skies, or better still a full paper of cyan colour. This will ensure that the vast majority of cleaning fluid is pushed through that particular nozzle.
For stubborn blockages we recommend you leave the fluid in over night to slowly work away at the problem.
