3.4.6 Fixing
The heat roller should reach the designated temperature necessary to melt the toner when the
sheet is in contact with it. At the same time, the toner solidifies when forced into the sheet under
pressure. Note: toner fixation can be influenced by fixing temperatures that are too high or too low.
3.4.7 Cleaning
The toner on the surface of the OPC is not completely transferred to the sheet so the wiper blade
cleans the OPC before the next sheet is printed.
3.5 Duplex Principle
When one side of paper has been printed and delivered from Output Roller Component 2, this
component contra-rotates, supplying the paper to the duplex unit, where any paper skew is
corrected. The paper is then moved from the duplex unit to the transfer module of the toner
cartridge unit through the channel between the correction roller and transfer roller. The back of the
page is then printed.
