After the BJ Cartridge is installed, the printer requires at least two
seconds to detect the presence of the BJ Cartridge. The cartridge
holder moves to the home position, and the printer automatically

If print quality problems such as white streaks, missing dots, or
irregular dots are found in the initial printout, clean the print head.
