So that your question can possibly be answered, we have forwarded it directly to the community. This is because we unfortunately do not have an effective user experience with the product.
As I have a new printer, I don't know everything yet. I think not as I can't find a duplex function. Note: At the moment I print on both sides by printing the odd pages first. Example 1,3,5,7,9, then I place the pages upside down (note the order), printed side "down" and print 2,4,6,8,10.
The printer does not have a paper tray as a drawer, as is known from larger devices.
However, the paper feed at the back has space for about 100 sheets. This means that you do not have to feed the sheets individually each time.
