Every day before using the printer, you must remove and shake the cartridges. This will agitate the ink and reverse some of the settling of pigments that occurs.

1. The printer should be off.
2. Since the cartridges are pressurized, first remove the rubber seal to release the pressure. You may want to use a paper towel so that no ink spills or splatters onto the printer parts.
   
   
   
   
3. Press the release lever and slowly pull the cartridge from the slot.
