Regarding the empty ink cartridges, ink is a lubricant for the print heads. Some color ink is used even if you only print in black or viceversa. If you printed with a color missing, you could destroy that print head from the friction of running without ink to lubricate it. That's why most printers won't allow you to print with a color missing even if you aren't using it.
If you allow a color to go empty, the residual ink in the head could clog and become permanently blocked. You would never be able to print that color again. So always replace ink cartridges as soon as they are empty.

Regarding the printer not being able to detect the size of the paper, you probably need a firmware update. Here is the support information from Kodak website.

And I have to agree with you, printers don't have a very long life cycle, but you should get at least 2 years out of it! Good luck!

Loading envelopesYou can load plain envelopes into the paper tray of your Kodak ESP 3 All-in-One printer.
IMPORTANT: Do not load envelopes with cutouts or cellophane windows in this printer.

1. Remove any other paper from the paper tray.
   
2. Insert one or more envelopes into the right side of the paper tray with the print side down and the envelope flaps on the right, pointing left.
   
3. Squeeze the paper-width guide and move it to its right-most position up against the envelopes.
   
4. Leave the paper tray open while the envelopes are loaded.
   

you should go to printing properties before printing and then set the size of the paper

Have you tried "fanning" the paper before loading it? This fixed my problem after a 6 hour battle, downloads of all firmware and restarting infinity times.

Restart your printer,put 8.5X11 papers in th paper tray.Align the gray coloured paper tray to the edge of the paper.Place any paper on the scanner glass of the printer and press copy on the printer.You will get a copy from the printer. Keep posting me ...
