Konica Minolta 1690MF causing Fuser Paper Jam
The problem is in weakened solenoid's (SD2) spring (10). That solenoid located under metal cover (13) on left side of 1690MF (if look at front of them). Required solenoid has red wires. Remove metal cover with 3 screw, unscrew solenoid and just slightly stretch spring (10). That is all.
