Does anyone know how to solve this issue? This Tecan Fluent hasn’t been used for a while and I tried to bring it up to use. I had this error and thought it was a bad tip-adapter filter, changed out to all new cone filters and this error still pops up on channel 4 when picking up tips.
Possibly a bad tip adapter sensor. when tips are mounted, they shift the black cylinder up against the tip adapter “box” that has the cables coming out and going into the channel. If that “box” doesn’t make full contact when shifted up, or if it’s not sensed, there’s no way for the instrument to confirm that a tip has been picked up successfully.
You could try manually holding it up to see if that passes and isolate the issue. Just be careful of moving parts.
