HP MFP3310 tries to pickup two sheets of paper even after replacing pickup roller and separation pad

[MAN2016]

It appears like a deliberate act by the printer because it raises the sheet twice in a row to pickup a second sheet while the first is going through the fusor.

It's the so called sticking solenoid problem.

The solenoid seats under right side cover, take good care of it and it will never jam again.

That did it! Problem solved and it's working smoothly. Thanks for your help!
