6. Turn on power to the PRL-200 and wait for the system to initialize.
7. Execute five (5) Purge cycles (Options menu on Handset Controller). Each purge cycle will draw
100 microliters of recoat material from the bottom of the recoat bottle through the red Fill tube and
inject material back into the top of the recoat bottle through the green Purge tube (see Figure 3).
Five (5) Purge cycles are required to fill the pump with recoat material and force any air out of the
pump system. This will take approximately 15 minutes to complete.
8. After the pump has completed its Purge cycles, the Inject tube that runs from the pump to the die
must also be filled with recoat material and purged of air. Have cotton swabs and cleaning
solution (NMP) available prior to proceeding.

9. Set the Inject to Die Qty to 100µl (Options menu on Handset Controller).
10. Execute the inject command (press “Select” on the Handset Controller).
11. Watch for recoat material to emerge from the die inject port located at the center of the center of
the bottom right die (see Figure 5). Make sure to collect the recoat material with a cotton swab as
it comes out of the die injection port. Do not allow recoat material to run down between the die.
12. Execute three (3) additional “Inject 100” sequences to purge air completely from the inject tube.
Note: Because the injection pump holds 100µl of recoat material, there will be a delay of
approximately one minute between the second and third inject sequences while the pump refills.
