About the influence of dirt on the printer
Printed images may have red, blue, or white dots or thin lines on their surface due dirt
or dust entering the printer. This is not a malfunction. These symptoms may become
worse depending on the storage conditions of the print paper or print cartridge. See
"Using the printer-Introduction" for details when handling print paper and the print
cartridge.
About cleaning printer heads
We recommend that you clean the printer heads with the head cleaner (supplied) when
you exchange the print cartridge. If printed images have thin lines, remove the print
cartridge, and clean the heads. Handle the print cartridge with care. See "Using the
printer-Introduction" for details when inserting the print cartridge.
How to clean the printer heads
Insert and remove the head cleaner several times. Store the head cleaner in the specified
case (supplied) after cleaning the printer head.
About the color of printed images
Printing images continuously or printing images at a high temperature may cause the
color of the printed images to change.
