One very good thing is that the Fuser Cleaning Web is the same throughout all 4 fuser versions. This is particularly good because it means that most fusers can run a second cycle by simply replacing the web and the Connector CRUM to reset the fuser counter. Other parts which are the same throughout the 4 versions include the Web Pinch Roll, the Web Drive Gear, the Fuser Drive Gear, the Heat Roll Bearings, Heat Sleeves (bushings), Thermal Fuses (thermostats), and the Picker Fingers.

There are three types of Heat Rollers (see Photo #2 for a side by side comparison of three types). The C35 version of the fuser has a Heat Roll which has a core of thick aluminum. The WC 232 version uses a thin steel core and the 165 version has a thin aluminum core. Word has it that the 5675 version uses a steel core roller too but that needs to be verified, and if it is steel, it needs to be compared to the WC 232 version.

There are two types of Pressure Rollers. The C35 version and the WC232 versions have a smaller Outer Diameter and the faster machines which require higher pressure (165 & 5675 versions) use a Press Roller with a larger Outer Diameter.

The Heat Lamps are different. Each fuser has two of the same lamp, but the wattage changes substantially from version to version.

C35 version = 99 Volts, 520 Watts

WC 232 version = 115 Volts, 905 Watts

165 version = 115 Volts, 1100 Watts

5675 version (remains to be seen)

Thermistors appear to be the same all around. It is possible that the thermistors report the temperatures to the machine logic differently, but it is unlikely seeing as how the labeling on each fuser shows the same stated temperature (392 degrees F / 200 degrees C).
