TWS QUADRA LASER

The machine is in good general electromechanical condition, we have a multitude of chargers of different types and we have been using it until a few weeks ago. We get rid of it because the optical unit gives many problems and when starting the machine, it passes the initial optical checks with difficulties. There are days that start the first and others that we just gave up after several hours of attempts. The TWS provider in Spain tells us that TWS no longer manufactures spare parts for the Quadra Laser, so we only see two options: disassemble the optical unit and try to clean it inside or sell the machine for parts. The first option does not appeal to us, so if a company already has a Quadra Laser, it could need replacement at some point. And if someone knows how to fix it, then they will take a very good machine at an incredible price.
