The Printhead Cartridge
The Memjet printhead cartridge contains over 70,000 inkjet nozzles. These nozzles are divided into ten 
rows; two rows of nozzles for each color channel. Due to the very tiny size of each nozzle and the high 
number of nozzles; it is not uncommon for some nozzles to become contaminated or clogged.
