Before replacing any PCBs, print out the F5/F6/F7 Parameter Lists using the F7, and F9 Modes. *3. After Mechanical adjustment, also adjust the Printer Registration, LSU Image Side to Side, etc. *4. To perform F8-09 or F8-11, open the Front Cover first before turning the Power SW ON. *5. When replacing the IT Belt, clean all the Metal Rollers, such as Bias Roller, and Feed Rollers with a soft cloth saturated with Alcohol first. Toner stuck on the Rollers will affect the Print quality, and may reduce the life of the IT.
