Fig. 4-65   Structure of BJ Cartridge

• Cartridge cover

This plastic cover is bonded to the cartridge body to prevent ink leakage

from inside the cartridge. As ink is consumed, the pressure inside the car-

tridge body falls below atmospheric pressure, and supply of ink to the head

is prevented. The ventilation holes on the cartridge cover maintain the

inside of the cartridge body at a fixed pressure to prevent this phenomenon.

• Ink sponge

This sponge is soaked with ink, and is contained inside the cartridge body

in a compressed state.

• Cartridge body

This plastic case couples the BJ print head unit to the ink sponge.
