Things to Check Before Installing a New Fuser

• Check that the pressure wedges are in place. These are essential for Lexmark fuser storage. Without them even a brand new OEM fuser will have developed a flat spot on the backup roller that will make the printer sound like it’s about to come apart.  Be sure to remove them before installation.

• Make sure the Narrow Media and Exit Sensors are functional, that the springs haven’t dislodged or the flag gotten pressed into the Lower Exit Guide Assembly.

• Ensure the internal wires are installed correctly, and that all the connectors, both internal and external, are firmly plugged in. And don’t forget the Fuser Guide Assembly at the front of the fuser. It needs to be straight.
