Operating manual:
Replaceable print heads (Hewlett Packard, some series of Lexmark, Canon series 2000/ 4000/ 5000).
Small dirt:
pour the liquid on paper towel and leave the cartridge on for about 15-30 minutes in position such how it is in printer, after this time clear up the nozzles area.
Large dirt:
fill up the flat pot with Rinse Solution and leave the cartridge for even 12 hours in position such how it is in printer
ATTENTION: Do not dip cartridge in Rinse Solution higher than nozzles level. Otherwise you can damage (delaminate) the plastic parts of cartridge.

You can use Rinse Solution in inside of cartridge. There is a higher efficiency of the cleaning process if Rinse Solution is heated up to approx. 55°C. It is very important to not cross this border. Because electronic plates are sticked, so too high temperature causes unsticking of them as well as damage of cartridge electronic. If you apply the liquid inside you have to suck off it with syringe with suction device after 10 minutes.

ATTENTION: There is a higher efficiency of the cleaning process if Rinse Solution is heated up to approx. 55°C. But it is very important to not cross this border.
