printer nov. 2015HP M601, M602, M603 VS. M604, M605, M606 fuser drive assemblies

With the release of the HP LJ Enterprise M604, M605 and M606 many are already asking about the compatibility of parts and specifically the fuser drive assembly. While some of the main internal components are interchangeable with the M601, M602, M603 series, the fuser drive assembly (TOP) is slightly different. (M604, M605, M606 pictured bottom)

The 2 differences are:

  1. The gear that drives the fuser (Top fuser, far right).
    1. The M601,2,3 has a smaller inner hub.
  2. The shaft the fuser drive gear rotates on (Bottom fuser, far right).
    1. The M604, 5, 6 has a larger shaft that is threaded for 1 screw to mount it to the printer’s frame for added stability.
