maintenance procedures; the ionizer bars are powered only when the UV lamps are
on.
- VideoNet pass-through and short cable: the external VideoNet cable from the print
server plugs into the printer leg. This is pass-through connector to a 3’ cable that
runs from the leg to the electronics box. When troubleshooting communications is-
sues, bypass this pass-through and connector by plugging the external cable directly
into the electronics box.
- UV power supply: see below
5. UV Lamp System
The UV system is somewhat intermingled with both the carriage assembly and the electronics
assembly. The twin lamps move with the carraige, but are not otherwise integral to the rest of
the X-axis mechanics. The power supply for the lamps is housed in the electronics assembly,
but is similarly unrelated to any other aspects of printer operation.
UV Lamp - identified as left and right. The lamp should be kept conceptually distinct
from the bulb. Just as in most lighting applications, the lamp is the permanent fixture;
the bulb is a consumable meant to be replaced over time. The lamp is replacable as
a complete FRM (exluding the bulb), but has these internal components:
- cooling fans (2)
- shutter motor
- shutter linkage
- shutter/reflector
- shutter home sensor
- shutter motor encoder
- lamp control board
- temperature thermistor
- air filter: this thin foam pad keeps ink dust and other particles from being pulled
into the fans and onto the bulb. The filters should be changed periodically.
UV Power supply - receives power input via the power distribution board, then
outputs via a separate cable to each lamp assembly. There are no servicable parts
within the power supply, it is replaced as an assembly.
