Abstract

Cartridges in an ink jet printer can be cleaned by users following a protocol set by the print manager. This cleaning function is especially useful when changing from a normal color print mode to a photo-realistic mode. Instead of having to purchase another cartridge with enhanced ink for photo-realistic printing, the user can ciean the existing ink out of the conventional color print cartridge and replace with the new ink.

Cartridges in an ink jet printer can be cleaned by users following a protocol set by the print manager. This cleaning function is especially useful when changing from a normal color print mode to a photo-realistic mode. Instead of having to purchase another cartridge with enhanced ink for photo-realistic printing, the user can ciean the existing ink out of the conventional color print cartridge and replace with the new ink.

tanks from the cartridge and then to click the OK button. This will initiate an extended priming function that will draw out all the ink from the cartridge channels and ink reservoir. As the priming begins, a message will appear to remind the user to put the newly removed ink tanks in their ink tank caps.

Step 2. After priming has been completed, a message wiIl prompt the user to insert ink tanks fded with cleaning solution which can be a co-solvent of the ink. The cleaning solution will be sold in the same manner as separable ink tanks. Upon clicking the OK button, the actual cleaning protocol will begin. This protocol entails a priming sequence to draw the cleaning solution...
