Digital BW, The Print

Hello,
I also posted this question to the Piezography group. I apoligize for the 
redundancy but I know this is a bigger group and I am hoping for a quick 
solution.

I just loaded up an Epson 7500 with selenium toned piezo ink. I am using 
IP5.6. And the ink I am using was purchased in July -I wanted to use up most 
of the OEM color ink in the printer since I have access to an Epson 9500 with 
the same inkset at my institution. I followed all the updated instructions, 
loaded the flush cartridges into the printer yesterday afternoon and loaded the 
Piezo ink cartridges today. I pulled each one out for a reset and then 
performed an initial load of the ink. My first test print looked good but my 
second larger print came out with a terrible yellow-green tint, as has every 
print since. I also tried to run the flush image that came with my old CIS 
system to no avail. 

I think two things could be wrong. When I ran the first flush my yellow cartridge 
light began to flash by the end of the cycle. The flush cartridges were bought 
this week at IJM and I had to break off tabs to get them to fit into the 7500 -its 
possible this cartridge might not have set correctly and therefore not fully 
flushed the yellow. Why would the first print look neutral and from neutral 
progress to a not so slight yellow/green tint? The only other possibility I can 
imagine is contaminated, badly labeled (maybe one or more cartridges are 
not really SL), or simply bad ink. I will try and find a CMYK image and run it 
with a color profile to identify if one ink is tainting the whole process. Any other 
words of wisdom? I do not have an owners manual can you purge one ink 
without dumping the rest? Jon is it possible to have a bad batch of ink? Since 
I am familiar with the selenium set I know this is not how it usually looks. 

Thanks in advance for your help.

As for flushing only one ink, if they allowed us to do that, think 
of all the money they'd lose! The only way to flush only one line is 
to release the head, take the cover off, remove the plastic bar that 
holds down the dampers, and pop the damper/inkline of the nipple. 
From there you can put a windex refilled flush cart in, and using a 
syringe with an MIS bottom-fill adapter, gently pull through enough 
windex to verify that all the color is gone. Replace the ink cart, 
pull ink into the damper. If you want to, you can also put a short 
piece of plastic tubing on the syringe and flush the head as well. A 
good trick to know if you ever get a really intractable clog. Of 
course, you want to get some paper towels under the head and ink 
lines before you go sqirting messy liquids around. I know this all 
sound radical, but it works, and is not very difficult I'm a 
cheapskate, this is how I change my inks in my 7500! And I'm about 
to figure out how to do it in my 7600 as well..

Best of luck, keep us posted
