Ink is smearing
Check the print settings
●When you print documents that use much ink, allow more time to dry before handling the
printouts. This is especially true for transparencies. In the printer driver, select the Best print
quality, and also increase the ink drying time and reduce the ink saturation using the ink volume

Troubleshooting installation issues
Problems printing an alignment page
When printheads are installed or replaced, the printer automatically prints a few alignment pages to
align the printheads. This process takes about 8 minutes, and the alignment pages may be discarded
after they are printed. If the printer does not print the pages, try to start the alignment process
manually (see 
To align the printheads).

configuration utility for the network card installed on your computer, and ensure that the profile
selected is the profile for the printers network.
