Problems successive with black resin


#1

My first black cartridge, resin was out of the cartridge fortunately it was protected by a plastic packaging …
After returning the resin, my new cartridge is not detected …
I saw in post that you can do a DIY with a piece of paper to raise the cartridge.
At the price of these cartridges, this DIY is not acceptable.
What is the formal solution of formlabs?
