m601 - duplexer

[dan_movie]

Hi all,

Do I need to change anything in the base m601 model for the duplexer to work ?

I purchased an automatic duplexer and assumed that if i installed it on the printer it would be recognized.

Everytime I print (with "print both sides" box cheked in the printer driver) I am given the manual option to flip the paper.

Any help welcomed.

Thanks

Dan

The 'automatic discovery' feature used by some (Windows) drivers on installation (or update) doesn't always work; ensure that the driver knows that a duplex unit is present on the printer (assuming that one is present):

• For the printer instance in question, bring up the Printer properties dialogue.
• Select the Device settings tab.
• Ensure that the duplex unit is set to Installed rather than Not installed.

You'll probably need to be logged in with administrator credentials in order to change the device settings.
