Copiers perform their function by creating an image on a piece of paper. This image is produced by applying powdered toner onto the page, then melting it onto the page with hot rollers. This melting process is called ‘Fusing’. Running a large print job will result in a build up to ‘Hot’ paper whilst existing the machine, this is normal. The machine runs at temperatures of 200 degrees Celsius. If the machine was to run to Hot, then the 2 thermal fuses would blow and cause a Service Call Error Code, disabling the machine. If this was to happen call us, otherwise, the ‘Hot’ paper is very normal.
