50.7 fuser error HP Color laserjet pro mfp

Good day. I am attempting to repair my HP Color laserjet MFP M181 printer that initially had streaks on the output. But i seem to have inadvertently damaged the "pressure release flag" (sorry not sure what its called.) and i am now getting 50.7 fuser error. Is there anywhere i can get just the "flag" or a damaged fuser unit. Please help
