Print quality troubleshooting
If printing over a LAN, it is possible that the LAN is too slow to meet the requirements of the print job.
If this is the case, the following corrective measures can be taken:
1Do not use the computer while printing. Close applications that use a large amount of computer resources.
2Convert the file PDF. Formats like PDF require less resources to print, which may solve your banding problem.
Lines are Missing, Too Thin, or Too Thick Description of problem
Shown below is an example of what you might see if you have this problem:
Corrective Action
1Check that the paper type loaded corresponds to the paper type selected in the front panel and in the software. You can verify the paper type selected through the Front Panel (Main Menu/Paper menu/View loaded paper).
2Check that the appropriate print quality settings are being used (refer to the User’s Guide for more information). Select the custom print quality options in the Print dialog, and if you are using best quality and glossy paper, try turning on the Maximum detail option. Reprint the job in case the problem has been solved.
3If the resolution of the image is greater than the printing resolution, a loss of line quality may be seen. You can find the Max. Application Resolution option in the Windows driver dialog's Advanced tab, under Document Options > Printer Features. Reprint the job in case the problem has been solved.
4Check the Printhead alignment status. If the status is PENDING, perform the Printhead Alignment (Main Menu/Image Quality Maintenance/Align Printheads). After alignment reprint the job.
5Check the paper advance calibration status. If the status is PENDING, perform the paper advance calibration (Main Menu/Image Quality Maintenance/Paper Advance Calibration/Calibrate Paper Advance). After calibration reprint the job.
6Use Part 3 of the Image Quality Diagnostic Print, check if there are a significant amount of nozzles out in the color that is actually causing the problem (if see you a problem with the Black color in the customer print, then only check the Black printhead in the Image Quality Diagnostic Print). If there is a significant amount of nozzles out then replace the defective Printhead.
