Paper upside down
Solution: Load paper in the paper tray print side down.
Cause: Paper in the paper tray was upside down.
Paper orientation error
Solution: Insert paper into the paper tray with the short edge forward and the print
side down. Slide the paper forward until it stops.
Cause: Paper in the paper tray was in landscape orientation.
Ink is drying
Solution: Leave the sheet in the paper tray until the message disappears. If it is
necessary to remove the printed sheet before the message disappears, carefully hold
the printed sheet on the underside or the edges, and place it on a flat surface to dry.
Cause: Transparencies and some other media require a drying time that is longer
than normal.
Print cartridge messages

Low on ink
Solution: Ink level warnings and indicators provide estimates for planning purposes
only. When you receive a low-ink warning message, consider having a replacement
cartridge available to avoid possible printing delays. You do not need to replace the
print cartridges until print quality becomes unacceptable.
If you have installed a refilled or remanufactured cartridge, or a cartridge that has
been used in another product, the ink level indicator may be inaccurate or unavailable.
