EPSON Stylus COLOR 670 Revision A
Operating Principles Overview 40
2.1.6 Ink System Mechanism
Ink system mechanism consists of Pump unit (including CR lock mechanism)
and Capping mechanism.
Ink system mechanism drives the Pump unit that presses cap to the Printhead
and ejects ink from Ink cartridge, Head cavity and Cap to the Waste ink pad.
CR lock mechanism assembled in the Pump unit locks the printhead to
prevent the head from slipping off the capping position so that the Printhead
nozzle surface is kept clean and wet.
2.1.6.1 Pump Unit and CR Lock Mechanism
The Pump unit is driven by PF motor. PF motor drive is always transmitted to
the Paper feeding mechanism and Pump unit, and therefore Pump unit and
CR lock mechanism drives according to the PF motor rotational direction, as
shown in the table below.
(*1): The PF Motor rotational direction = seen from the PF motor pinion gear.
Figure 2-9 shows the operating principles of the pump mechanism.
