Re: IJC/OPM

2003-03-31 by grdglass

Antonis and Robert,

Thanks for your suggestions.  I have run a couple of cleaning cycles 
and performed an alignment on my 2200.  Neither worked.  I also 
worked up a new test file, just in case the file I had been using was 
corrupted.  No luck.

So, I am stuck for awhile, because I am running OPM off an iBook that 
I do not use for image editing.  I use a PC for images and will have 
to wait for IJC for Windows before I can check out my 2200.  I have 
no need to buy both platform versions.

Antonis, since I see the banding in only the 100% patch with OPM, 
does that mean the problem definitely lies in the black jet?  Would 
your black single-jet profile for troubleshooting tell me anything 
definitive?
