Hi, I recently had an issue with the ‘vacuum out of range issue’. I’ve read the couple other threads to troubleshoot the issue from cleaning the Thomas pump and the vacuum tubes. There was mention of bypassing the filter, but wasn’t clear on which filter they were referring to. I finally found out that the issue on my printer had to do with a filter looking think that’s connecting the vacuum tubes near the printer head unit (attached picture). I bypassed this unit, and the vacuum issue seems to be gone. My question is whether anyone knows what the unit is called and how I could find a replacement (a generic one) for it? Thanks.
