Guide Rails The print carriage assembly is traversed across the screen via two linear guide
rails. Both guide rails are fixed in position to the machine printhead casting.
Carriage Rails The print carriage rails are a linear bearing type rail onto which the print carriage
is secured.
Print Carriage
Motor
The print carriage motor is a dc servo type motor with integral gearbox and
encoder. This motor is fitted at the rear right hand corner of the print carriage
rail system. The print carriage is driven through a pulley and timing belt system
located on the right hand side of the machine, (Drives and Sensors figure of this
chapter refers).
NOTE
Technical information on servo motors is detailed in the Sensors and Motors
chapter of this manual.

Temperature and
Humidity Sensor
The temperature and humidity sensor option is utilized during the applications
process of printing. In order to achieve maximum print quality during the
printing process, a continuous temperature and humidity monitor of the machine
printhead area is required.
The sensor provides the operator with accurate real time information of the
internal temperature and humidity levels of the machine. This is displayed on
the machine monitor Printer - Status window.
Figure 9-6 Temperature and Humidity Sensor
The sensor is a 4 wire transmitter which measures relative humidity, utilizing a
capacitive sensor, and temperature with an NTC resistive type sensor. Essen-
tially the sensor behaves like a variable source of current or voltage that is
adjusted dependent upon the temperature and humidity conditions.
Two linearized output signals are read by the machine PC NextMove card
(Temperature - ADC2 / Humidity - ADC4). Real time information is displayed
on the machine monitor Status Window.
The parameters of the temperature and humidity sensor is:
