Installing the BJ Cartridge
The BJ cartridge contains ink and a print head for printing. Each
cartridge can print about 700,000 characters approximately.
Prepare the cartridge by the following the instruction sheet that comes with it.
Open the top cover, then the paper cover.
Before using a new BJ cartridge, perform the head cleaning
operation first, otherwise, it may print poorly or not print at all.
