Problems with Graininess Description of problem
Shown below is an example of what you might see if you have problems with graininess:
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 printing is on the correct side of the paper.
3Check that the appropriate print quality settings are being used (refer to the User’s Guide for more information). In many cases, you can correct grainy printing by raising the print quality settings. 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).
6After Paper Advance Calibration, reprint the job.
Paper is not Flat Description of problem
If the paper does not lie flat when it comes out of the Printer, but has shallow waves in it, you are likely to see visible defects in the printed image, such as vertical stripes. This can happen when you use thin paper that becomes saturated with ink.
