Mel, this is what I found in the online manual:
Set the
Ink Drying Wait Time longer.
Doing so gives the time enough to dry the printed surface so that paper curling and ink blots are prevented.
(1) Make sure that the machine is turned on.
(2) Open the printer properties dialog box.
See Opening the Printer Properties Dialog Box Directly from the Control Panel.
(3) Click the
Maintenance tab and then
Custom Settings.
(4) Drag the
Ink Drying Wait Time slide bar to set the wait time, and then click
Send.
(5) Confirm the message and click
OK.
Make sure that the actual size of the paper is suitable for automatic duplex printing.
The sizes of media suitable for automatic duplex printing are A4, Letter, A5, B5, and 5" x 7".
Load paper of suitable size and then press the
OK button.
Make sure that the
Page Size or
Paper size setting matches the actual size of the paper with a size suitable for
automatic duplex printing.
First, check the
Page Size or
Paper size setting in the application software you are printing from.
Then, check the
Page Size setting on the
Page Setup sheet in the printer properties dialog box (Windows) or the
Paper size setting on the
Page Setup dialog box (Macintosh).
Note
Depending on the version of the application program, the automatic duplex printing may not be supported.
Make sure that the type of loaded paper is suitable for automatic duplex printing on the
Main sheet (Windows) or the
Quality & Media sheet on the
Print dialog box (Macintosh).
Note
To switch to manual duplex printing, follow the procedure below.
Open the printer properties dialog box, clear the
Automatic check box on the
Page Setup sheet, and reprint.
When performing manual duplex printing, note the following.
If you are printing three or more pages of a document with manual duplex printing, one side of all sheets of paper will be printed first. Turn over the paper and reload the paper in the machine, and then the reverse side of all sheets of paper will be printed. Be careful not to change the order of paper in the stack.
The procedure for reversing the paper varies depending on the staple side and printing orientation. Follow the on-screen instructions.
