To fill the hopper:
1. Open the hopper lid, located on top of the hopper on the right side of the printer.
2. Place the filled powder cartridge upside down on top of the hopper with the valve handle
(marked with the Formlabs logo) facing out.
3. Pull the valve handle out until it stops. Wait for the cartridge to empty.
4. Push the valve handle back in to close the cartridge.
5. Leave the cartridge in place for approximately one minute to let the plume of powder
settle. You may continue setting up the printer before removing the empty cartridge
from the hopper.
5.4.4 Checking the IR sensor
The Fuse 1 uses an IR sensor to monitor temperature
changes inside the print enclosure. Readings from the
sensor greatly influence the print quality, accuracy, and
reliability of the printer. Any obstruction of the sensor
adversely affects prints and is likely to result in a print
failure. The image shows a dirty IR sensor that needs
to be cleaned.
The IR sensor may be difficult to reach for some
users. If necessary, keep a step stool nearby.
To check the IR sensor:
1. Open the IR sensor access door on the top of the printer.
2. Locate the IR sensor, which has a grey cap with an LED in the center. The LED turns green
or orange, depending on the status of the IR sensor.
3. Grip the cap and pull the IR sensor off its mount. The IR sensor is held in place with magnets
and should come out with little force.
4. Inspect the lens on the underside of the IR sensor.
5. If the lens is clean, reinstall the IR sensor. If the lens
looks contaminated, clean it with a new polyester
swab or PEC PAD wetted with ethanol and reinstall
the IR sensor. Reconnect the IR sensor to the yellow
wire inside the IR sensor panel.
6. Place the IR sensor cap into the mount and allow the
magnets to secure it. The LED turns green when it is
properly aligned.
If the LED turns orange:
a. Place the cap into the mount until you feel the
magnets pull the cap down.
b. Rotate the cap until it comes to a halt and cannot rotate any further. If the LED is still
orange, it may be necessary to subtly turn the cap in either direction.
7. Close the access door to the IR sensor panel.
