To reproduce stable colors, use other image quality adjustments as necessary, such as when changing screens or papers or when hue is important.
This section describes flows for Image Controller IC-417 or Image Controller IC-313.
These flows are available:
Adjustment flow when changing the screen
Regular adjustment flow (Standard)
Regular adjustment flow (High accuracy)
Items to be adjusted differ depending on whether the RU option is used or not.
To not continuously perform the series of adjustment of the image quality adjustment flow, perform Gamma Automatic Adjustment (Adjustment Flow When Changing the Screen / Regular Adjustment Flow (High Accuracy)), and then resume from the next adjustment.
When changing the screen, perform the following image quality adjustment.
This adjustment is the same as the adjustment when the machine was introduced (setup).
• Without the RU option (Relay Unit RU-509)
Density Balance Adjustment (Adjustment Flow When Changing the Screen)
• With the RU option (Relay Unit RU-509)
Density Balance Adjustment (Adjustment Flow When Changing the Screen)
To use special paper or to enhance the accuracy of the automatic adjustment, use [Each Paper Type Color Adj.]. For details, refer to Color Density Control (Adjustment Flow When Changing the Screen / Regular Adjustment Flow (Standard) / Regular Adjustment Flow (High Accuracy)).
This adjustment is recommended for all customers in their daily operations.
Perform this adjustment at any of the following timings:
6 hours after turning on the power of the machine
When between 1,000 and 2,000 sheets of paper have been output
Immediately before the job for which hue is important is output
Others, such as when you cannot get the desired hue
• Without the RU option (Relay Unit RU-509)
• With the RU option (Relay Unit RU-509)
Check that the RU option is used.
When the RU option is used, calibration is automatically executed.
In addition to "Regular adjustment flow (Standard)," perform this adjustment especially in the following cases:
Immediately before the job for which hue is important is output
When the color stability is not desirable (you want to increase the accuracy of reproducibility)
When the paper type is different
• Without the RU option (Relay Unit RU-509)
Maximum Density Adjustment (Regular Adjustment Flow (High Accuracy))
• With the RU option (Relay Unit RU-509)
To use general paper, set to Default Adj. Data.
To use special paper or increase the accuracy of the automatic adjustment, [Each Paper Type Color Adj.] is recommended. For details, refer to Color Density Control (Adjustment Flow When Changing the Screen / Regular Adjustment Flow (Standard) / Regular Adjustment Flow (High Accuracy)).
