|One of the last phases paper goes through in a laser printer is the Fusing Process. The Fuser Units or Kits are simply two rollers that will reach a temperature of approximately 200 degrees C (392 Farenheit), enough to melt the toner particles to the paper passing through the rollers. Specifically, the paper containing toner particles is sandwiched through the rollers, bonding the toner to the paper via heat and pressure. The Fuser Assembly will need to be replaced every so often due to natural wear and tear, as well as from dust particles latching onto parts of the printer creating unnecessary and unwanted friction. Inkgrabber.com offers the Original Equipment Manufacturer (OEM) or Genuine Fuser Assembly Kits which are created by the printer manufacturer and tested to ensure quality performance. All products, including the HP RM1-1535 , are ISO 9001 certified, meeting the highest standards and offered at only $278.99.
