2.13.5.4 Vacuum Voltage Sensor Relay
This relay senses the voltage when powering on the imagesetter. Refer to Figure 2-13.
If the relay senses 220 volts, it configures the transformer for a 115 volt output to
the vacuum pump. The green light on top of the relay sensor should come on at
220 volts. If the light is off, then 220 volts can be output to the vacuum pump.

2.14 Media Transport System Overview

The media transport system automatically loads, punches, advances, cuts, and
rewinds media from multiple supply sources into and out of the drum image area.
This process entails pulling media out of the supply cassette, applying it to the drum,
firmly affixing the media to the drum, and, after imaging, pushing media into the
take-up cassette or on-line bridge.
The media transport system consists of:
• Rollers and drives
• Supply and take-up supports
• Autocutter
• Optional punches/clamps
The system also consists of all hardware necessary to advance and retract the media
from the supply cassettes through the drum and into the take-up cassette.
