This probably cleaned off the dust but it left behind fragments of the sponge vrush on it. I typed single letter on the device and hit print while the sponge was pressed against the rubber roller. For this I put vodka on the provo ides mini sponge brush. The tape was slipping on the rubber roller.

I tried to address this by manual pressure on the lever operated by the cartridge door knob. In the first instance I thought the head clamp was not exerting enough pressure. It looks like I used a combination of tactics to fix this. (If you try to pull the tape of out the cartridge by hand it's worth noticing that it requires substantial force. I think this has the effect of reducing the traction the rubber had on the tape.

Regarding ribbon not moving during printing on a Dymo LetraTag LT-100T with a variety of 12mm Dymo LetraTag label cartiges.

I then cut off all but a quarter inch of the white tape, reinstalled the cartridge, and now have a working Dymo. The ribbon spool hole is located about 1/2 inch above and to the right of the “O” in the work DYMO. You can prevent the black tape from moving by using something that fits in the hole, like a pencil eraser, to keep the ribbon spool from moving. I managed to grab this small length of white tape and pull it out about 2 inches while preventing the black printer ribbon from moving at all. There was already about 1/4 inch white tape sticking out from the point where the black printer ribbon heads back into the cartridge. This point is about 1/2 inch below the letter “D” in the brand name DYMO on the cartridge. I removed the cartridge, got out my magnifying glass, and, looking at the side of the cartridge you see when it is installed in the DYMO, found the spot at which the white tape is supposed to separate from the printer cartridge ribbon.

Had same problem with first tape cartridge I installed, which is the same one that came with my Dymo model 160.
