Items not to be handled
Never remove, disassemble, or adjust any of the items indicated below.
2-1 Mounting the rail for the image transfer belt unit
Never remove the rail for the image transfer belt unit. It has been mounted at the factory using a positioning jig to ensure
that it is level.
If the rail for the image transfer belt unit is removed, the image transfer belt unit will become twisted, the paper will not
be transported straight, the belt will become damaged, and the colors will be mispositioned.
2-2 Mounting the developing motor
Never remove the developing motor. It has been mounted at the factory using a jig and the drive gears adjusted to ensure
optimum gear meshing. If the developing motor is removed, the gear meshing will become too shallow or too deep,
noise will develop, and imaging problems such as the mispositioning of color, streaks, and color unevenness will occur.
2-3 Mounting the rack motor
Never remove the rack motor. It has been mounted at the factory using a jig and the drive gears adjusted to ensure opti-
mum gear meshing. If the rack motor is removed, the gear meshing will become too shallow or too deep, noise will
develop and imaging problems such as the mispositioning of color, streaks, and color unevenness will occur.
2-4 Variable resistors on the circuit board
Never adjust the variable resistor on the circuit board. It has been adjusted at the factory.
