1.8.1 Printer Mechanism
Like the printer mechanism for earlier printers such as the St
lus
COLOR 600, the paper feed
PF
motor drives both the paper feed
mechanism and the ink pump. However, the ink pump operates onl
when the carria
e is in its home position and the PF motor is turnin
the
appropriate direction.
Another important feature is that the printhead is one unit, combinin
both black and color ink nozzles.
