Description
Tests communications between
components.
• Tests the data queue in the
DATA PCI card.
• Tests the Windows interrupt.
Tests the encoder's reliability by
comparing readings from multiple
runs along the X-axis.
Compares the following parameter
values with the minimum
requirements.
• physical memory
• available memory
• free space on disk
• monitor resolution
Verifies the presence of RFID tags
on all loaded material cartridges, and
tests them by writing to and reading
from each one.
Checks if the following voltages are
within 5% of the required voltage:
• 40V to the print heads by the VPP
power supply
• 12V to the height thermistors by
the VDD power supply
Analyzes the thermistor readings
when the block is full and when it is
empty.
Tests the interlock in the printer
cover.
Tests the temperature level in the
build-tray area.
Tests the read/write capabilities of
the print-head driver cards.
Checks the control of voltages
supplied to the print heads.

• If only the FIFO Interrupt test fails:
Faulty Windows interrupt.
Faulty encoder.
Failure of RAM memory allocation in
the printer computer.
• Faulty RFID reader.
• Faulty RFID reader power supply.
• Faulty or misaligned RFID tag.
• High level of electromagnetic noise
around the RFID tag.
• VPP power supply:
Faulty head drive(s).
• VDD power supply:
Faulty height thermistor(s).
Faulty thermistor.
• Failure of interlock mechanism.
• Faulty latch.
• Disconnected cable.
Faulty temperature sensor (OHDB).
Faulty print-head driver card(s).
Faulty print-head driver card(s).
