1.9 MAIN COMPONENTS

The LQ-850/ 1050 printer includes the following major subassemblies:
Model-53 10/5360 printer mechanism
MONMA board (main board)
MONPL board (control panel)
Figure 1-15 shows the LQ-850/l 050 component locations.
NOTE: In LQ-850, the paper tension unit and push tractor unit are excluded.

1.9.1 Printer Mechanism

The printer mechanism is composed of two stepper motors used in carriage move and paper feed, a
24-pin printhead, four sensors (home position, paper end, friction/tractor, and platen gap sensors), and
metal frames.
The printer mechanism has two paper guides (depending on the paper type), a push type tractor unit,
and an optional pull type tractor unit. These features enable the LQ-850/ 1050 printers to print on a
wide range of usable paper types.
The construction of the mechanism has been simplified to make maintenance very easy.
