Interlock System Test Procedure

Introduction

This section outlines the procedure for testing that all of the safety interlock systems of the T220UV BG model printer are
functoning properly. Note that the non-BG model does not have a blue reset button - instead it requires that you release the
Emergency Stop by twisting it slightly clockwise, then press ACCEPT to restart the printer.

Activating any one of the three Emergency Stops will trigger the Machine Safeguarding Category Four Interlock System,
causing any carriage and/or gantry motion to stop, the UV Lamps to have their power removed, and will require the T220UV
system to reboot. The T220UV system will need to be RESET (press the blue RESET button when prompted after the reboot
sequence starts) to allow the printer to complete its power up sequence.

Opening any one of the four Capping Station or Blot Station doors will trigger the Machine Safeguarding Category Four
Interlock System, cause any carriage and/or gantry motion to stop, the UV Lamps to have their power removed, and generate
a "Door Open" Message, but will not require the T220UV system to reboot. The T220UV system will need to be RESET
(press the blue RESET button when prompted on a BG model and ACCEPT on non-BG) to allow the printer to perform any
Gantry/Carriage motion and printing functions.

Tripping either of the two Hinged Gates will trigger the Machine Safeguarding Category Four Interlock System, causing any
carriage and/or gantry motion to stop, the UV Lamps to have their power removed, and generate a "Door Open" Message,
but will not require the T220UV system to reboot. The T220UV system will need to be RESET (press the blue RESET button
or ACCEPT when prompted) to allow the printer to perform any Gantry/Carriage motion and printing functions.

Note:

Due to the advanced technical nature of this procedure, you may want to have an Océ service representative perform

the test.

Purpose

To establish a clear procedure for determining the Machine Safeguarding Category Four Interlock System is functional.

Caution:

IMPORTANT SAFETY NOTE (BG only): It is critical for Operator and other person's safety that the Hinged Gate

operates with minimum resistance. If the Hinged Gate is stiff, or binds at any point along its travel, it must be removed and
repaired to provide smooth motion.
