I have had a lot of work done on my 9600 over the past few months. First, I
had my 9600 print head replaced (twice actually, the first replacement was a
disaster), the pump cap assembly and also the wiper blade replaced. Despite
that, I began to find magenta blobs on my paper. (I use Conecolor inks, by
the way.) In an effort to remedy that situation, I had the flushing box and
all of the dampers replaced. I also emptied out the LM and M cartridges and
filled them with more ink in the hopes that would help. (To make sure the
newer ink was actually flowing through the printer, I ran 3 power cleans.)
This last round of work, all done by the Epson tech rep, was not effective.
I still get blobs after I have made several prints in a day. If I clean
behind the print head, the wiper blade, and the pump cap, and then wait over
night, the next print I made is OK. My nozzle checks are mostly perfect,
What to do? The Epson tech guy suspects the Conecolor inks and can only
suggest that the Conecolor inks be flushed out of the machine and replaced
with Epson ink. In that way, he wants to demonstrate that the inks are to
blame. Naturally I don’t want to do that. But is it possible that the inks
are to blame? I likely bought them in April 2012, although I had bought
Conecolor inks as long ago as August 2010, and I have not segregated the
April 2012 stash from earlier ink inventory.
When I pointed out that I have been using the Conecolor inks without
problems for several years, and that I therefore suspected the second print
head to be defective, just as the first replacement print head had been, he
said that ink manufacturers often change their ink formulas and don’t notify
customers that they have done that. He also thinks it’s unlikely that the
2nd print head is to blame, but, then again, he can’t explain why the first
print head didn’t work for me.
I haven’t called back overall Epson tech support because of this impasse.
If I can tell them in no uncertain turns that the inks aren’t causing these
problems, I will do that. So, what is your advice? What is the expiration period for Conecolor Inks? Has the formula for them been changed over the past year or two?
Thanks, Dana, for your response.
