QTR-Quadtone RIP

I  have been using QTR for some time and have a new problem: prints
using my Epson 1280 now show perceptible horizontal bands or stripes
for the first and last 1/4" of each print. Can this be an alignment
problem?
If not, what might it be?

Thank you.

Realign or clean your heads or both.

Thank you for your suggestion. But if the problem is either in
alignment or head cleaning, how would that account for the banding
appearing only at the very beginning and end of the prints, not in the
central portion of the print?

I would agree adolphamster, with you that head alignment and nozzle 
clogging would not exhibit such banding at the begining and end of 
prints.  Since I read your post I noticed this too with my 2200 and MS 
GQ inks.  I think it only happens when I don't upsize a file and try 
to print from QTR at more than 100%.  I only print less than 100% now 
and upsize before I send to QTR- man do I miss Qimage.  No more 
banding.  Let us know if that is on the mark.  -p

I have been experiencing the same problem with the R800 at 1440dpi. It 
seems that the problem vanishes most of the times at 1440 Super. No 
problem at 2880dpi (shifting the problem to the use of too much ink and 
blocking blacks). Funny that the banding occurs always at the top and 
at the end of an image. Until now I thought that it was just a R800 
profile issue.

Ignacio

I think you hit the nail on the head! And thank you very much. I've
been relying upon either QTR or my Epson print driver to resize my
prints. Following your input, I selected an image resized it to the
desired final size (using Bicubic sampling) in Paint Shop Pro and then
printed at actual size.

Problem gone!!

How about that!

Thank you again.
