Belt fusing is adopted in this machine.

The surface of the fusing belt is made from polymide and is covered with silicone rubber that is coated by fluororesin. The fusing belt is driven by the fusing roller (Φ57).

  1. Fusing roller material
    The following material is used to shorten the warm-up time for MP C6503/C8003, to improve the image quality of the coated paper for Pro C5200S/C5210S.
    • MP C6503/C8003: Sponge rubber
    • Pro C5200S/C5210S: Solid rubber
    The elastic layer of the fusing belt of Pro C5200S/C5210S is thickened in order to let the belt enter indentations in the paper that existing belts cannot be inserted into. This improved fusing belt imposes pressure and heat equally on all parts of the paper, and dramatically enhances fusing efficiency.

  2. Fusing Roller
    In this machine, the fusing roller materials are different between Pro C5200S/5210S and MP C6503/8003 in order to suit different types of users as follows.

    Merits

    • Superior to MP C6503/8003/C6502/8002 in image quality of coated paper
    • High productivity

    Demerits

    Longer warming-up time

    • Pro C5100S/C5110S: Less than 300sec

    *1 The outer diameter of the fusing roller is larger than the predecessor model. This increases the nip width and the fusing temperature is lowered.

  3. Heating roller
    The heating roller (Φ35) is made of a magnetic shunt alloy. The flux shield plate (aluminum) and the shaft (aluminum) are included in the roller.
  4. IH Coil (external heating IH)
    In this machine, an IH coil heats the heating roller and the fusing belt.
    The IH coil is employed in order to realize fast heating and temperature uniformity.
  5. Pressure Roller (Φ55)
    The pressure roller (Φ50) surface is made of iron covered with silicone rubber that is coated with a fluororesin tube. The pressure roller has a fusing lamp in it.
  6. Fusing Lamp
    There is a fusing lamp [B] inside the pressure roller [A]. This heats the pressure roller when starting up and when warming up. It also keeps the machine heat during waiting.

  7. Fusing separation plate
    Other models have multiple separation plates but this model has only one plate. This prevents folding, jams, and damage to the image.
