MATERIAL DELIVERY MODULE (MDM) INSTALLATION
The MDM is made of stainless steel and has eight casters for moving and maneuvering it while installing or removing it from
the machine. There are also handles on the MDM that help the user to transport and maneuver it into and out of the system.
HOT SURFACE: The area underneath the MDM where the heaters are located is hot (about 40°C (104°F)) —Do
not reach underneath!
Make sure that the elevator is at its lower limit by first homing the print applicator, homing the elevator and then
moving the elevator down -10. You must also ensure that the print applicator is in its storage location on the MDM. Assuming
the MDM is outside the ProX 950, the following steps describe how to install it.
IRRITANT!: While performing this procedure, wear protective clothing, disposable nitrile gloves, and goggles .
Note: Move the MDM very slowly . Sudden starts and stops can result in material spills, even with the MDM lid in
place . Continuous slow movement is important .
1. Make sure that the connecting cables are out of the way before you
attempt to place the MDM into the machine.
2. Wearing nitrile gloves, remove the cover from the MDM, wipe off any
excess material from inside the lid by carefully applying some isopropyl
alcohol to a paper towel and wiping excess material off of cover. When
finished, store lid in a safe place.
CAUTION: Ensure no alcohol gets spilled into material . Alcohol
will contaminate material causing it to build ineffectively .
3. Open the front doors of the ProX 950 and slowly roll the MDM into the
machine.
4. Roll the MDM until the
locking pins
located on the inside of the ProX 950
are lined up with the brackets on the MDM. Turn the pins until they set
into the brackets. The left side of the bracket has a hole for the pin to set
into. The bracket on the right has a notch. When the locking pin attaches
properly, the MDM will also hit the bumper at the back of the machine.
