Ricoh sp 8200dn printer is only pulling paper from tray 2 (color tray) and tray 3 (plain paper tray). Trays 1 and 4 will not pull any paper (both white trays)

SOURCE: HP Officejet 7410 AIO keeps saying out of paper when plenty of paper loaded

Once remove both the trays and insert them again and if the problem persists, power cycle and semi-full reset the all-in-one.

Where the paper comes out there is a little black thing that is supposed to stick out. Somebody has pushed it in.
