Immediately after borderless printing, the trailing edge margin is soiled during regular printing iPF8400 Immediately after borderless printing, the trailing edge margin is soiled during regular printing Cause Depending on your printing environment, after borderless printing in which the leading and trailing edge of the roll is cut automatically, any ink adhering to the cutter unit may rub off on the next printed document. Corrective Action Follow these steps to change the Between Pages setting of Drying Time to a value between about 30 seconds and 3 minutes before trying borderless printing again. 1. On the Main sheet of the printer driver, click Advanced Settings by Media Type. 2. Select an ink drying time in the list for the Between Pages setting of Drying Time. Printed colors are inaccurate Cause Color adjustment has not been activated in the Advanced Settings of the printer driver. Corrective Action In the Advanced Settings of the printer driver, access Color Settings in Color Mode to adjust colors. Colors have not been adjusted on the computer or monitor. Refer to the computer and monitor documentation to adjust the colors. Adjust the settings of the color management software, referring to the software documentation as needed. The Printhead nozzles are clogged. In the Windows printer driver, Application Color Matching Priority is not selected. Print a test pattern to check the nozzles and see if they are clogged. (See "Checking for Nozzle Clogging.") →P.920 Click Special Settings on the Layout sheet of the printer driver and select Application Color Matching Priority in the dialog box. There may be a slight difference in how colors are printed after Printhead replacement because of individual variation among printheads. Execute color calibration. Printhead characteristics gradually change through repeated use, and colors may change. Execute color calibration. Color may change slightly even on the same model of printer if you use a different version of the firmware or printer driver, or when you print under different settings or in a different printing environment. Follow these steps to prepare the printing environment. 1. Use the same version of firmware or printer driver. 2. Specify the same value for all settings items. 3. Execute color calibration. When reinstalling the printer driver, you changed the region selection of the Media Configuration Tool. Changing the region selection of the Media Configuration Tool deletes the region-specific paper information originally registered on the printer before installation. Using paper with deleted information when executing color calibration will prevent the resulting calibration adjustment value from being applied to all other types of the paper. Prepare paper compatible with calibration in the newly selected region and perform calibration again. Troubleshooting Problems with the printing quality Banding in different colors occurs Cause The paper feed amount is out of adjustment. Printing does not proceed smoothly because print jobs are interrupted during transmission. Corrective Action Adjust the feed amount.
