Operating Principles Overview 38
2.1.5.2 Pump Unit Mechanism
The PF motor also controls the Pump unit mechanism (including the Change lever) as
well as the Paper loading/feeding mechanism. The drive of the PF motor is always
transmitted to the Pump unit. (And also, its drive is transmitted to the LD roller through
the Clutch mechanism & the Change lever.)
On these printers, the Pump unit mechanism including the Change lever plays a major
role expecting the ink eject operation. And, these operations control depending on the
PF motor rotational direction as the following table below.
(*1): The PF motor rotational direction = seen from the left side of the printer.
1. Ink eject operation (usual operation)
The ink is absorbed from the ink cartridge, the ink cavity and is ejected to the
Waste drain ink pad from the cap when the ink tube is pressed by a roller in the
Pump unit.
Following figure shows you the overview of the Pump unit mechanism operation

Transmission Path :
PF motor pinion gear (CCW) → Spur gear 60 (PF roller & Paper eject roller) (CW)→ Spur gear 10.8 (CCW)
→ Combination gear 18.28 (CW) → Spur gear 27.2 (Pump unit gear) (CCW)
( * Above transmission pass = seen from the right side of the printer)
