Manufacturer Narrative

(b)(4).Customer reports: jammed, stuck leadscrew.Per visual inspection: no cosmetic damage noted.Several attempts were made to pair inpen, every time app displayed dose doesn't match and inpen not found.The inpen does not pair with commercial mobile app.The inpen screw retracts when dialing and advances when turning dose knob and high resistance while dispensing and dialing noted.The dose button was removed and no dust / debris under the dose button or dose knob noted.Inpen was cut open and after inspection it was found that the encoder pattern wheel tabs rotating and traveling off the keyed slots of dose nut guides.Encoder pattern wheel should never rotate.This causes an unexpected travel of the encoder pattern wheel creating resistance to dial and dispensing.Also contamination build up found caused by encoder wheel tabs rubbing at the walls of the dose nut.In conclusion: it was determined that pairing anomaly and the customer complaint jammed / stuck lead screw was confirmed due to encoder pattern wheel rotating and traveling against the walls of the dose nut.
