1. Check that the paper type you have loaded corresponds to the paper type selected in the front
panel and in your software. To check on the front panel, use the View information key .
2. Check that you are printing on the correct side of the paper.
3. Check that you are using appropriate print-quality settings (see Print options on page 77 ). In some
cases, you can overcome a print-quality problem merely by selecting a higher print-quality level.
For instance, if you have set the Print Quality slider to Speed, try setting it to Quality. If you
change the print-quality settings, you may wish to reprint your job at this point in case the problem
has been solved.
4.
Go to the front panel and select the Ink menu icon , then Printhead information to see the
printhead alignment status. If the status is PENDING, you should align the printheads. See Align
the printheads on page 59 . After alignment, you may wish to reprint your job in case the problem
has been solved.
5. Go to the front panel and press the View information key to see the paper advance calibration
status. If the status is DEFAULT or RECOMMENDED, you should perform paper advance
calibration: see Perform paper advance calibration on page 35 .
If the problem persists despite all the above actions, contact your customer service representative for
further support.
The paper is not flat
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 defects in the printed image, such as vertical stripes. This can happen when you use thin paper
that becomes saturated with ink.
