Epson DFX-9000
Continuous form feeding
Continuous forms are fed by a pair of Pin belt tractors attached to the left
and right ends of the Tractor shaft (square shaft). A continuous form fed
by the Pin belt tractors moves along the paper guide section where it is
picked up by the DV roller F and 1st Nip Roller. Continuing upward, it
is fed across the Platen and directed by the Card guide on the Carrier
unit. After the form has passed the Card guide, it is transported and
ejected by the Paper eject unit.
The Pin belt tractors, DV roller F and Paper eject unit are all driven by
the LF motor.
