How are you loading the paper in the printer?

I had a simply spectacular smudging problem with my R2400 a couple of weeks ago. Ink would seep right across the page, making for wonderful "artistic" images, but very frustrating printing. It had me completely baffled until I noticed that the images were printed on the BACK of the paper... sigh.

Those were color images printed on glossy paper, but I've gotten some really nice B&W results using the Epson Heavyweight Matte paper. I use the top-load feeder and drop in one sheet at a time. I get great results with both the OEM inksets and with the G&G ink I get from http://www.4inkjets.com/

Hope your problem was as easily fixed as mine!

I have had excellent results printing on Moab Entrada with my Epson R1800. The Entrada paper is printable on both sides so there's no right or wrong there. That paper does come in two thicknesses: 190 and 300 gsm and my printer has a box to check for thick paper under Maintenance. I check the thick paper setting and feed the paper in the single sheet guide when printing on the 300 gsm.
I downloaded the profile from Moab and use the recommended, for my printer, enhanced matte paper setting. I realize we're using different printers with different inks but perhaps some quality control problems could have similar solutions.

Thanks for the advice everyone. I'm getting better help here than from the manufacturers. I am loading paper thru the front manual feed path. Yes, i also checked the "thick paper" box and I even cleaned the nozzles just in case. I've now used two separate paper manufacturers (MOAB and Hanhelhume) and about 4 different paper styles all with the same results. I love the saturation (blackness) of the black inks but can't get rid of the smudging.

Do you know if I can use ICC profiles with PS Elements 4.0 or Paint Shop ProX - or does this not relate to my problem.

I got one smudge free print using epson "enhanced matte" paper but the tones were pretty drab. The blacks looked more like gray than black.

The reason I bought this printer was to do bw prints on fine art, heavy, textured papers but it seems these are the only papers my printer DOES NOT like! Please help again.

The front loading method with the R2400 is to be used only for card stock and other very thick and stiff media, not for papers around 200 to 300GSM like those made by Moab or Hahnemuhle, which should be loaded through the top paper paths on the printer.

The cause of your smudging is probably loading standard weight and thickness papers through the front loading slot of the R2400.

I am now using the rear single sheet path and Epson "velvet fine art paper" with great results. I assumed the front path would be appropriate for very thick (300gsm) papers but i guess I was wrong. Live and learn.

A bit late with this reply but hopefully the person who posted it will get to read it !! I had exactly the same with my Epson 2000P, and the solution was simple. I don't know how similar the 2400 is to the 2000P, but this is all I did - if you lift the main cover up, on the right of the printer, as you look at it, you will see an adjustable lever (well you do on the 2000P). Make sure the lever is set to "+" not to "0". When I did that, the smudging stopped instantly !!
