Printout Of Scanning Compensation Data (Function Mode 05) - Ricoh G157 Service Manual

Printout of Scanning Compensation Data (Function mode 05)

The machine prints out a white and black level data sheet for scanning
compensation.
IMPORTANT
Always do a scanning operation before you perform this function. This
function cannot print out correct scanning compensation data if scanner
initialization is not done first. This is because the scanner initializes white
and black level data during initialization, and this is included in the
scanning compensation reference data.
1. Enter the "Maintenance" mode.
2. Press "0" then "5".
3. "WHITE LEVEL 1" appears on the LCD.
4. The machine prints out the scanning compensation data list. This contains the
following:
a) Black/white data graph
b) Bright output adjustment value (REFH-PWM)
c) Illuminant adjustment value (LED-DATA: R)
d) Illuminant adjustment value (LED-DATA: G)
e) Illuminant adjustment value (LED-DATA: B)
f) Black level MIN data
g)
Black level MAX data
h) White level MIN data (R)
i) White level MIN data (G)
j)
White level MIN data (B)
k) White level MAX data (R)
l) White level MAX data (G)
m)
White level MAX data (B)
n) Background color compensated data
o) Black level data
p)
White level data (R)
q) White level data (G)
r) White level data (B)
5. After printing, the machine returns to the initial display of the maintenance
mode.
NOTE: If any data is abnormal, its mode will be printed in inline style (white on
black, for example: 0000).
