MX-3114N OPERATIONAL DESCRIPTIONS 13 – 30
c. Half-tone process control operation (Toner patch generation and half-tone correction operation)
1) When the machine enters the half-tone process control mode, the secondary transfer unit enters the free state.
2) While changing the dither pattern step by step by the MFP PWB, a number of toner patches in different densities are generated on the F
side and the R side of the primary transfer belt.
F side: The color toner patch is generated.
R side: The black toner patch is generated.
3) Each toner patch density is detected by the image density sensor, and each toner patch density are compared with the reference gamma
to calculate the correction amount.
4) The dither pattern in the actual operation mode is generated in the MFP PWB with the reference gamma and the correction amount.
