Part 2: Product Specifications BJC-6000 1.3.3 Photo BJ cartridge The Photo BJ cartridge, mounted on the left side of the carriage for photo printing, is a disposable print head with 144 in-line nozzles, and accommodates replaceable photo-black, photo-magenta and photo-cyan ink tanks. It has 144 nozzles (48 nozzles for each of the three colors), aligned vertically. It uses drop modulation technology for high speed, high quality printing, where smaller ink-droplets are discharged for low density images and larger ink-droplets for denser images. The black ink is a dye-type and the photo-cyan and photo-magenta inks are three times lighter in color density than normal color inks. Replace the relevant ink tank and/or Photo BJ cartridge if the ink-out error is issued or if satisfactory printing cannot be achieved even after the stipulated cleaning and head refreshing operations have been performed. It is recommended to replace any cartridge which is at least six months old, i.e., unpacked at least six months earlier. The Photo BJ cartridge has a life of approximately 3000 pages and a new color ink tank provides for approximately 280 pages of a 7.5% duty pattern. Figure 2-4 Photo BJ Cartridge 1.4 BJ Cartridge Container The BJ cartridge container is used to store non-installed BJ cartridges. The lid of the container must be closed fully to prevent the ink in the nozzles of the BJ cartridge from drying out. Each BJ cartridge container can store one Black, Color, or Photo BJ cartridge. Always store a BJ cartridge with its ink tanks installed. The BJ cartridge containers can be connected together. Figure 2-5 BJ Cartridge Container 2-4
