4) Paper feed mechanism and sheet feeder
The built-in sheet feeder is driven by the paper feed motor. Plain paper as well as
coated paper, transparencies, back print film, envelopes, etc., can be loaded and fed
automatically into the paper feed mechanism.
Driven by the paper feed motor, the paper feed mechanism rotates the feed rollers to
feed the paper vertically.
When printing transparencies and back print film, remove each sheet from the paper
output tray immediately after it is printed. This is to allow enough time for the ink
to dry.
The paper ejection operation of this printer is performed using the
RESET button
.
3.2 BJ Cartridge
3.2.1 Black BJ cartridge structure
The black BJ cartridge consists of a 128 nozzle print head and integrated ink
cartridge.
1) Cartridge cover
The plastic cover is attached to the cartridge body to prevent the ink from leaking
inside the cartridge.
As the ink is consumed, the pressure inside the cartridge decreases in relation to the
atmospheric pressure. This makes it harder for the ink to be supplied to the head.
To prevent this, the cartridge cover is provided with a pressure adjusting hole for
maintaining constant pressure inside the cartridge body.
2) Ink sponge
The sponge is soaked with black ink. It is compressed and stored in the cartridge
body.
3) Cartridge body
The plastic case connects the ink sponge with the bubble jet head unit via the ink
filter.
4) Bubble jet head unit
Ink is ejected through the 128 bubble jet nozzles, according to the print signals
received through the signal contact.
