Print quality troubleshooting
3 Check 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.
4 Check 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.
5 Check 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).
6 After 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

vertical stripes. This can happen when you use thin paper that becomes
saturated with ink.
Shown below is an example of what you might see if you have problems
with the paper not being flat:
Corrective Action
1 Check 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).
