Thanks Wieck, for your insight. Optical sensors are clean, and no error code reported. Though MP feed solenoid won't energize thus no paper pickup from MP tray with error Tray 2 Jam error when print attempted with paper in Tray 1.

If you get a Tray 2 jam error, and theres no paper jam, then the paper
jam sensors are faulty. Check these again with a multimeter if they are
mechanical, and clean the optical ones out throughly as Peter Wieck said
