I've just purchased a C400 for use in our office. I'm unable to disable Duplex printing on it though. I've changed the driver option to 1 sided print and have also disabled 2 sided in Earth Smart. I've tried the Postscript and PCL6 drivers but nothing seems to make a difference, everything prints duplexed. Just wondering if I'm missing anything obvious please?
Hello Yaffle,
Does it print duplex from all applications? I would check your application menu first. I found the steps on how to duplex print, so check the steps to make sure you have it turned off. If you really want to turn it off permanently, you could disable duplexing as an installable option from the driver.
