2.2 Printer Mechanism Operating Principles

The EPSON Stylus Color 980 has black and color heads united in one
unit which includes a total of 480 nozzles: 192 nozzles for black (96
nozzles x 2) and 96 nozzles for each color. This printhead enables the
printer to print 3 lines by one pass at 10-cpi printing. Also, new ASF/
pump switching mechanism offers higher throughput with quick feeding
motion at continuous printing by combining the trigger solenoid and
independent pump/ASF motor. Production of PTS signal using the
encoder belt also enables the printer to improve printing accuracy,
detect paper jam in the CR operational range, and print during
acceleration/deceleration (on normal paper / 360 x 360 dpi only).
See Figure 2-1 for the printer mechanism block diagram.
