Ribbon-Feed Mechanism - Epson L-1000 Technical Manual

PRINCIPLES OF OPERATION

2.2.11 Ribbon-Feed Mechanism

The ribbon-feed mechanism consists of the ribbon cartridge and the ribbon-feed section. The ribbon-driving
gear always turns counterclockwise, via the gear trains shown in Table 2-21, irrespective of the direction of
the timing belt.
Figure 2-65 shows the ribbon-feed mechanism. The inked ribbon is inside the cartridge case in an endless state,
held between the ribbon-feed and ribbon-pressure roller mounted on the ribbon-driving gear. The rollers are
driven by the movement of the gear and the inked ribbon is fed.
A ribbon-braking spring is attached at the exit of the cartridge case to prevent the ribbon from slacking. A rib-
bon mask is installed for preventing the ribbon from staining the paper.
