1.7.1 Printer Mechanism
The printer mechanism of the Stylus Color 900 has black and color
heads united in one unit which drives larger amount of nozzles (180
nozzles in total) than ever. Also, for a new ink jet printer feature, the
printer has succeeded in printing in the acceleration/deceleration areas
by reading the slits on the linear scale to improve the throughput. This
improvement in throughput mostly depends on the Pump/ASF switching
mechanism. In other printers, the gear trains are switched when the
trigger lever hits the mechanism along with the carriage’s movement. In
Stylus Color 900, however, the exclusive solenoid is directly attached to
the mechanism instead. With the solenoid which switches drive at a
higher speed, the printer can control high-speed paper ejection system:
the printer bring the leading edge of the second sheet to the printing
position just before ejecting the first sheet.
The motors equipped with the printer are CR motor, PF motor, and the
Pump/ASF Motor, same as for the Stylus Color 800.
