After 3 cleaning cycles, if the nozzle check is still not in perfect condition, don't operate "cleaning" anymore. 

Just leave the printer power on for at least 30 minutes and then operate "cleaning" again as the previous procedure. 

This is to secure not to suck  too much air into the cartridge and let the ink flow down automatically.

paper with optical brighteners

It is essential that the correct paper is chosen for your application.  Most papers on the market contain optical brighteners. 

These fluorescence will drown out much of the color of the invisible inks.  So, we would suggest users use light yellow plain paper or light blue plain paper for invisible printings.
