Recently, my printer (Deskjet 3630) has been having issues with printing my documents double-sided. The only option it gave me was to duplex-print manually, while previously there had been an option to do this automatically.
I wasn't quite sure what the issue was at first, but eventually figured out that it had something to do with one of the properties of the printer.
If I go to the printer's properties --> device settings --> Automatic Duplex Unit, it tells me that said unit is not installed. Since the printer previously did print my documents double-sided (automatically!), it seems odd that I can't change this setting back to installed. The bar is greyed out, so the only option is 'not installed'.
Is there some possible fix for this? I have tried unplugging the printer, removing and re-adding its driver (as well as the printer itself), but nothing seems to work.
Thanks for the help!

Hi,
The HP Deskjet 3630 printer does not offer any automatic duplex print capabilities, your printer hardware is not capable of performing a such, your printer never offered such an option.
You may find the printer specifications below
Paper handling Duplex printing - Manual (driver support provided)
http://www8.hp.com/us/en/products/printers/product-detail.html?oid=7491299#!tab=specs
You may only perform manual duplexing with the HP Deskjet 3630 printer by following the steps on screen and manually reloading the page with the printed side facing down into the tray.

Hi,
Thank you for the information! I actually just figured out what the issue was. The code for the 3630 printer is (F5S57A), while mine has the code (95E5CB), despite saying '3630 series'. Looked at my printer again and it turns out it's a 3632.
Does this matter? It seems like the driver that the 3632 supports is the same as the 3630, but I can't find much information about the model specifically.

Hi,
The entire HP Deskjet 3630 series offer the same specifications, including the Deskjet 3632 model.
None offers auto duplex printing for the entire series, here are the technical specifications which lists the same and clearly listed any model of the series:
