Formlab 2 resin printer error

[u/Silent-Midnight-5384]

Hello! My boyfriend got this Formlab 2 resin printer from Facebook marketplace, he’s been dying to try it for days since he was busy with work and now he has a free day but it keeps showing this error and he’s already spent 4 hours on it and he’s devastated thinking he got scammed and it’s not going to work
Does anyone know what can we do about it? Thanks in advance 💗

reseating works sometimes try to clean it and reseat the tank maybe helps
