2-32 Functional Analysis

Figure 2-19 Media cutter assembly.

➀–Cutter home switch. ➁–Cutter motor.

NOTE: The DC gear motor and the home switch can also be

replaced separately.

The cutter assembly consists of:

• Media platens

• Cutter bar

• Home switch

• DC gear motor

• Linkage

• Take-up media present sensor

Internal platens guide the media through the reciprocating cutter mechanism. A DC

gear motor, which attaches to the end of the cutter through linkage, drives the cut-

ter. One revolution of the motor output shaft causes the linkage to reciprocate the

cutting bar. A built-in sensor (a mechanical-micro switch) signals when the cutting

cycle completes. The media cutter assembly also includes the take-up media

present sensor.

2.14.6 Supply Cassette

The supply cassette is a daylight loadable cassette that accommodates a 250 foot

roll of 4 mil media in widths ranging from 16 to 36 inches. The cassette may be

adjusted continuously between these widths.
