6.3 Signal Contacts
The scanner cartridge is recognized by TOP.S, DIAS, and CCHK signals. The scanned
image output to the printer is transmitted with a SCLOCK signal in sync with a SDATA
signal. The scanner is controlled by the internal register setting signals, CMD0, 1, 2
and 3.
For the location and assignment of signals, refer to

6.5 Calibration
Calibration is performed by using the white calibration sheet. In the calibration
process, to create calibration data, data such as the printer's internal temperature,
black level data, and white standard data used as a reference in scanning, are sampled
and then corrected in terms of shading and white balance.
The scanner application retains the past 5 calibration data samples and saves them in
a file.
When a scanning operation is performed, a value from the compiled temperature data
that is within ±5°C of the printer's internal temperature at the time is downloaded to
the scanner controller. The scanner application requests calibration when there is no
compiled data within ±5°C.
