TIM-Mag Unit
TIM-Mag (Transferred Image Reading Module - Magnification) provides the following
functions:

Auto color calibration

Auto registration adjustment

Real-time registration adjustment

Main scan shading correction
Here, we will focus on the two registration functions; auto and real-time registration
adjustments.
CIS Detects the image magnification ratio in main scan direction and the
coordinates of the image and media. Registration adjustment is
performed based on these readings.
Trigger photo sensor Detects the leading and trailing edges for registration adjustment in sub
scan direction.
Encoder Feeds back the sensor readings for registration adjustment in sub scan
direction.
NOTE: When the TIM-Mag Unit or its surrounding components are replaced, certain
adjustments are required to retrieve the registration accuracy. See RTB
RD0A5024 for detail.
