Do you get the message on the printer or PC ?
Please let me know, if you still need help on this problem.
I can only help you, if I get all the information from you and as you can see that, you have replied me back after 6 hours from my first reply. So, I could not get back to you , as I was offline at that time. If you want to continue then, I can still help you.
try putting a piece of paper in the manual feed slot for small photo paper
that printer is really bad at deciding which slot it wants to print from based on the type of print it is doing and absolutely refusing to change its mind or let you over ride it or even telling you where it wants it.
