3rd Mirror Position Adjustment

[2]: 3rd Mirror (C)
[3]: 3rd Mirror (M)
[4]: Mirror Adjustment Motors (
)
[5]: Temperature Sensors
Each color Yellow [1], Cyan [2], Magenta [3] has a mirror. The machine uses the
mirror motors (
) to adjust the position of each mirror to correct color
registration errors on the ITB in the main scan direction. Color registration errors
occur if all four color-toner images do not cover each other exactly on the ITB.
The 3rd mirror for black (K) does not have an adjustment motor. (The position of
black toner on the ITB is used as a reference point to adjust the positions of the
other colors.)
Exposure Unit Temperature Sensors
There are temperature sensors [5] near the f
θ
lenses to monitor the temperature
inside the exposure unit.
The f
θ
lenses are made of plastic. The magnification ratio of plastic lenses may
vary slightly with temperature. The CPU uses the feedback from these temperature
sensors to adjust the mirror positions during MUSIC calibration. This corrects color
registration errors on the ITB.
