106 Maintaining the Printer Chapter 7Using InkThe print head is the device that projects the ink onto the paper. During aprint operation, the printer heats the ink to boiling point in the nozzle toform a bubble. The bubble expands until there is no room left in the nozzlefor the ink. The printer then ejects the ink onto the paper through thenozzles on the print head.Ink formulation is the most critical component of a Bubble Jet printer. Theink you use must meet these guidelines:o It must be able to be heated and cooled over 6,000 times per secondwithout clogging.o It must dry very quickly without bleeding into other colors.o It must work with different media and software, while providingcorrect color matching with the printer driver.o It must be environmentally friendly.Canon has more engineers dedicated to providing the best results foroutput on Bubble Jet printers than any other organization.
