The 1400/1430 does print great, but the thickness of the paper you stack in the feeder can very as far as how many. It may not be the greatest with a handful of sheets and if you want a printer that works better with this option, I'd recommend the P400/P600/P800. P400 and P600 are both 13" models, but it's the colors that are different. P800 matches the P600 color set, but is a 17".
The best option is to make sure you "fan" the sheets apart from each other before feeding them so this may help with the feeding issue. It sometimes works and other times it will still jam or attempt to take another sheet at the same time. If going with a pigment printer, the feeder is slightly different, but can still do the same thing. For a better ink usage printer, I'd recommend either the P600 or P800 as the inks are bigger (1400/1430 (470 page yield), P600 25.9ml and P800 is 80ml).
P800 has been a great model and many customers love how it functions and prints. Not saying the 1400/1430 is a bad printer, but it depends on what you're printing and how much to say if it's a good option for your needs.
