The Fixing Heater PCB Assembly, like the AC Driver Assembly, is located inside the power inlet assembly. Unlike the AC Driver PCB Assembly, there are not 110V and 220V versions. Versions do differ, however, depending on the type of cooling fan being used. Any printer with an internal video controller needs both a lower fan and a more powerful upper fan to dissipate the heat generated. Fixing assemblies are more likely to fail and melt gears when the fan does not provide enough cooling. SX and TX printers without internal controllers use RG1-0714-050, which powers the low power fan. All others use RG1-1438-030, which provides more power to a higher wattage fan. Fans have also been revised and the new ones move more air with less power.
