The Fixing Lever on the Xerox WorkCentre 5855 is a component in the printer’s fuser assembly. The fuser is responsible for bonding toner onto paper using heat and pressure. The Fixing Lever helps maintain the necessary pressure between the fuser rollers to ensure that the toner properly adheres to the paper. This lever is essential for the smooth functioning of the fuser, and if it becomes damaged or worn, it can result in issues like print quality problems or paper jams. If you're troubleshooting print quality issues or jams, the Fixing Lever might be a potential cause, and you may need to inspect or replace it.
