2.1 Overview
This chapter describes the operating principles of the printer
mechanism and electrical circuits.
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.
