Data Recall Not Used
The copier firmware has a test pattern with eight stepped gradation scales for each color
(KCYM), including background white, for Text and Photo modes. The ACC procedure
automatically calibrates the gamma curve when the user selects ACC. Generally, here is
what happens:
• The operator prints the pattern.
• Operator places the pattern on the exposure glass.
• Copier scans 8 lines (1 for each color in text mode and one for each color in photo
• Machine corrects the printer gamma by comparing the ideal settings with the
• Machine combines the corrected gamma curve with the High, Middle, Low ID
• Machine calculates the ID max (amplitude and gamma curve) based on data from
Note: This is done only with machines that support ACC.
