The swing plate assembly, a small obscure assembly in the right rear of the HP LaserJet 4200 through 4350 series of printers, has recently become very popular. Why? One reason is that, obscure as it is, it has a very important job: to couple the printer’s main drive assembly to the fuser. The other reason is that if the fuser isn’t fully seated (which is unfortunately a common problem in this series of printers), it will “bounce” when the swing plate attempts to drive it. This can damage both the gear in the fuser and the gear in the swing plate. (more…)
