    Probably wired different and drive gear differences.

    Two things. The electrical connection are different. The c554 has much bigger bearings supporting the fuser sleeve roller. The c454 has the small bearings that disintegrate.

    Probably the most common issue with the models that use that style fuser.

    Brush Cleaning Roller A2XK740400

    Teflon Cleaning Roller A2XK740301

    Cleaning roller bushing A2XK742901

    Brush roller bushing A161771000

    There may be new style / color bushings?

    Ball bearing 4120550302


    The small bearings that disintegrates is used in a lot of finishers, FS 527, FS 534, etc. I take them out to use in these fusers when I strip parts off finishers before trashing.

    Also available as a repair kit HHFRC754E-C754A, used for 554, 654 and 754 models. Recommend using hi-temp grease on bushings.

    Also wanted to add I've seen both cleaning rollers removed and machine ran 100's of thousands prints with no fuser issues. All single side of course, don't think it would hold up well with a lot of 2 sided.

    I've personally left the cleaning rollers out out for a few weeks while getting parts and returning. No unusal build up on rollers, etc. Rollers look fine. Think you could leave them out permanently on high volume account that run mostly 20lb plain paper single side only, but don't hold me to it

    The whole assy. with both cleaning rollers or just one of the roller assys? If just one of the rollers, which one? We've never tried removing either of them so I was wanting the inside info.
