8 Examine test pattern A for adjustment. Determine the pattern in which banding is least noticeable. Note •If banding seems least noticeable in two patterns but you cannot decide which one is better, choose an intermediatevalue.For example, choose 11 if you cannot decide whether pattern 10 or 12 is better.9 Press ▲ or ▼ to select the pattern number you have decided, and then press the OK button. Test pattern B is printed for adjustment. Note •If you printed test pattern A on a sheet, follow the instructions on the Display Screen and use another sheet of thesame type of paper.Additionally, after test pattern B is printed, follow the instructions on the Display Screen and remove the sheet.10 Examine test pattern B for adjustment. Determine the pattern in which banding is least noticeable. 11 Press ▲ or ▼ to select the pattern number you have decided, and then press the OK button. The adjustment value is now registered, and adjustment is complete. Fine-Tuning the Paper Feed Amount Fine-Tuning the Paper Feed Amount If the contrast is uneven or banding in different colors appears at 50 mm (2.0 in) intervals in printed documents, try executing Adj. Fine Feed during printing to fine-tune the feed amount. Note •The Adj. Fine Feed menu is only displayed during printing.Additionally, it is displayed when you have selected Automatic or Print Quality in Adj. Priority in Feed Priority. (See "Menu Settings.")→P.648•Always execute Adj. Quality before Adj. Fine Feed.Once you execute Adj. Quality, the Adj. Fine Feed value will revert to 0. (See "Automatic Banding Adjustment.")→P.738 (See "Manual Banding Adjustment.")→P.739 Perform adjustment as follows. 1 On the Tab Selection screen of the Control Panel, press ◀ or ▶ to se- lect the Settings/Adj. tab ( ).

Adjusting Line Length Adjusting Line Length To ensure that lines in CAD drawings are printed at exactly the right length, use Adjust Length to adjust the amount that paper is advanced. There are two options in Adjust Length : AdjustmentPrint and Change Settings . • AdjustmentPrint After a test pattern is printed, you will measure the discrepancy based on the results of printing. • Change Settings No test pattern is printed. Instead, you will measure a document already printed to determine the discrepancy. Additionally, two modes are available in both AdjustmentPrint and Change Settings : A:High or B:Standard/Draft . Choose the mode that suits your particular printing application. • A:High This setting is applied when Highest quality or High is selected in Print Quality in the printer driver. • B:Standard/Draft This setting is applied when Standard or Fast is selected in Print Quality in the printer driver. Note •We recommend executing the adjustment if you have changed the paper type or paper size.•Always check the Adj. Priority values before using Adjust Length.

When "Stop printing?" is displayed,press ▲ or ▼ to select "Yes", and then press the OK button.8 Press ▲ or ▼ to enter the amount of discrepancy, and then press the OK button. If the scale is shorter than the actual size, use a positive setting value. If it is longer, use a negative value. The feed amount can be adjusted in 0.02% increments. Adjusting Color on the Trailing Edge of Sheets Adjusting Color on the Trailing Edge of Sheets If printed sheets are affected by banding in different colors by the trailing edge (about 20–30 mm (0.8–1.2 in) from the edge), try adjusting the feed amount of the trailing edge of sheets. Important•This adjustment is only possible when feeding paper from the Top Paper Feed Slot that can be set up with a margin on thetrailing edge of 3 mm (0.12 in). Paper that does not allow a margin of 3 mm on the trailing edge is automatically ejected, andthe adjustment is not available. Note •We recommend using the type of paper you use most often for adjustment.•For banding in different colors over the entire printed area of sheets or rolls (not only at the trailing edge of sheets), try adjust-ing the overall feed amount. (See "Automatic Banding Adjustment.")→P.738Items to PrepareSheetsOne sheet of unused paper of at least A4/Letter size Perform adjustment as follows. 1 Load the paper. • Loading Sheets in the Feed Slot→P.554 iPF6400 Adjusting Color on the Trailing Edge of SheetsUser's Guide Adjustments for Better Print Quality Adjusting the feed amount 743

Adjusting the Vacuum Strength Adjusting the Vacuum Strength When printing on heavyweight paper or paper that curls or wrinkles easily, if the Printhead rubs against paper, adjust- ing the level of suction against paper on the Platen may improve results. Important•Paper rubbing against or becoming caught on the Printhead may jam or result in printed documents that are soiled.

Using this mode requires adjustment or configuration of the settings of your monitor, the source application, the file for printing, and the printer driver. Important•Monitor matching may not be applied, or these settings may not be configurable or adjustable, depending on your monitorand the source application.Printing Images to Match Monitor Colors iPF6400 User's Guide Color Management Monitor Matching 748
Note •Printing in exactly the same colors as displayed on the monitor may not be possible due to differences in the monitor andprinter color gamuts.•Calibrating your monitor requires a measuring device.•Because colors appear different under sunlight at different times of day, we recommend following this procedure in a room notexposed to sunlight.• Monitor Matching The sequence in monitor matching is as follows. 1 Calibrate the printer. Calibration improves color consistency by compensating for slight differences in how color appears due to indi- vidual variation among printheads or conditions in various printing environments. (See " Color Calibration Using the Printer Sensor .") →P.758 2 Calibrate the monitor. i1-Display and similar measurement devices are commonly used. Set white point to 6500K or 5000K , Gamma to 2.2 , and brightness to 120 cd . The exact procedure varies depending on your monitor and measurement device. 3 Open the file to print and configure settings in the source application. Display the file in the sRGB or Adobe RGB color space. Configure settings to prevent color conversion by the application. In Photoshop CS3, for example, select Color Management in the Print dialog box, and then select No Color Management in Color Handling . 4 Configure and adjust printer driver settings. Select Monitor Matching using the Matching Method , and then select the Monitor White Point that you set up in monitor calibration. In Color Space , select the color space used when displaying the file in the source application. Note •To print multiple times using the same value, we recommend opening the Printer Driver dialog box from the Systemmenu and configuring the appropriate settings. (See "Accessing the Printer Driver Dialog Box from the Operating Sys-tem Menu (Windows).")→P.183 For instructions on configuring printer driver settings for monitor matching, refer to the following topic, as appropriate for your computer and operating system. • Printing Images to Match Monitor Colors (Windows)→P.749 • Printing Images to Match Monitor Colors (Mac OS X)→P.751 Printing Images to Match Monitor Colors (Windows) Printing Images to Match Monitor Colors (Windows) By calibrating your monitor and configuring settings in the source application in advance, you can complete settings to print in colors that are as close as possible to the colors displayed on the monitor. Important•Before using this feature, you must calibrate the monitor and configure settings in the source application. (See "Printing Im-ages to Match Monitor Colors→P.748")1 Choose Print in the application menu. 2 Select the printer in the dialog box, and then display the printer driver dialog box.
