12 | Calibrating the PCU
3. Set the temperature to 190.0 °C on the control panel using the temperature arrows and then press
.
The set temperature indicator on the right displays (in green) the temperature you set. The
temperature indicator on the left displays (in red) the actual temperature.
4. Set the Speed control knob to 1.5.
5. Wait for the PCU to warm up to the set temperature; this takes approximately 5 minutes.
The light on the Heater switch comes on while the PCU is warming up, and then turns off and on
periodically after that. The light indicates that the heating element is working to maintain a stable
temperature.
6. Place three THERMAX temperature strips on the coated side of an Epson DirectPlate Aluminum test
plate, one in the middle and one on each short end of the plate, 1/2 inch from the edge.
WARNING:
The plate edges are sharp. Use of gloves is recommended to avoid injury.
7. Place the test plate on the input tray with the long edge toward the slot, coated side up, and gently
push it in so it engages with the roller. The plate feeds through the PCU at the set speed.
If the plate is not pulled in by the roller, check that the feed direction switch on the side of the PCU is
set correctly.
8. Check the indicated temperature on the temperature strips as the test plate leaves the PCU to see if it
is in the range of 150 to 160 °C. If the temperature is low, decrease the speed; if you see burning or the
temperature is high, increase the speed.
