Laser printer parts manufacturer Metrofuser ( has issued a warning for business users of laser printers. Removing certain parts when the printer is turned on will harm the device irrevocably. The company’s research reveals as much as 10% of failures can be traced back to improper handling of these devices.

Metrofuser has issued the warning for all makes and models of laser printers and MFPs. A company spokesperson said this is not an engineering or design problem but more of a failure to follow best practices. A significant portion of the failures are occurring when end-users remove the fuser while clearing paper jams or when service is performed with the device is turned on.

This problem is so widespread it traces back to devices with older hot roller technology all the way up to the latest instant on technology. Faults show up as error codes referencing damage to the fuser, power supply or other electrical components.

Metrofuser is asking the service community to reevaluate procedures and educate their end-users on the proper handling of these sensitive devices. To avoid damage simply turn printer off before removing or installing fusing assemblies. Failure to do so WILL destroy printers heating elements, thermistors and/or power supplies.

Furthermore, Metrofuser is now equipping all of its fusers with warning labels that can be applied to printer to help inform installers and end users. Labels are also available by calling Metrofuser at 908-245-2100 Ext 128.
