Digital BW, The Print

Hi,
I'm doing some proofs before a large mural on my 2100 ... they have started to show banding in spite of a clear nozzle check.

What should I do next????

thanks,
Richard

Try various head alignment settings. The horizontal alignment is notoriously
difficult to get right. My horizontal alignment sheet shows so much banding
it's impossible to tell which of the boxes are best aligned. I remember
Clayton had good results with the lower settings (1-2) in spite of obvious
gaps on the alignment sheet.

I'm not sure if you have to go through the whole alignment process after the
horizontal alignment. The color alignment is slow and tedious to go through.

Also try both the thick and normal paper settings. Sometimes on of them will
have banding while the other is fine.

Hi Richard

I just had a banding problem on an R220 when printing on heavy stock
(HPR 308).  Nozzle checks were fine and printing on EAM didn't show
banding.

It turned out that I needed to realign the heads (using the
maintenance function supplied with the printer drivers) for a thicker
paper.

I didn't manage to completely remove the banding from the HPR prints
but it's much less pronounced and quite difficult to see.

(I realise this is a completely different printer, but might help you
solve your problems.)

Good luck

Chris

Richard, You may also want to adjust your print quality and dry time. If the
banding is not file related, then adjustments to the printer may get rid of
them. Is this a normal size print for you? Sometimes techniques used at one
print size don't work so well at other print sizes.  Good luck.

One more thought, it might be a paper feed problem.  You might try
cleaning the rollers.  Maybe built up coating residue is affecting it.
Just grasping at straws...

Clayton

Richard;

Look at your nozzle test carefully with a 3x-5x lupe. They should 
not simply all be there, but each one should be straight and clean 
with any little hooks on the ends, anf the gaps between them should 
be even and consistent between colors, If you have hooks or other 
minor imperfections, you likely have an ink build-up under the head. 
I'm sure you've already tried wiping with a strip of cleaning-fluid 
soaked fabric, but you may need to get more aggressive. I recently 
solved a similar problem by making a fabrick sleeve that fit over a 
thin blade bent so I could slide it under the head and apply a 
little pressure whlie wiping it.  Worked well, the printer went from 
almost unusable to almost perfect.
