Digital BW, The Print

Ive tried the suggestions involving Windex to unclog the printhead, however
the black still isnt printing... I fed a roll of paper towel through the
feeder, got a dripper to drop windex on the paper towel and manually turned
the cogwheel. I did get some ink deposits dissolved onto the paper, however
the head for black still isn't printing... What should I do next??


Thanks!!

Kevin.

As I posted a couple of days ago, I didn't agree that this method 
helps with clogging at all, but only with dirt/hair/ink deposits at 
bottom of head (giving a compeltely different symptom). Although I 
think feeding the towel in through the paper feed is a novel approach.

Please search back and find my post that describes my opinion on what 
is wrong and how to fix it.

Hint- less cleaning cycles, more purge patterns with real Epson carts 
installed. Forget the paper towell trick.

I am not sure if you use cartidges or a CIS. If you use the 
cartridges, check the links on this page ... 
http://www.piezography.com/ts/index.html

You will find one of the links is to the page of info about the foam 
pads in the printer cartridge chamber causing problems with the black 
ink position.

If it is the cartidges that you use, this may be one thing to check.

Best of luck.

I found that my CIS lasted about a year and a half before the black channel 
quit.  I had poor black channel performance and tried many ways to clear 
the "clog", including injecting the head directly with Windex.   When I got 
a good test pattern, I ran a black-only test image at high speed and 
watched as the ink lay-down quickly went from total black to just a few 
black lines on the page.  I deduced from this that it was the CIS that was 
starving the black head for ink, not a clogged head. I bought a new CIS, 
installed it and I'm printing normally again.  Others have commented that 
the black channel (not the head) suffers from clogging due to evaporation 
of the solvent through the Nalgene tubing.

Excellent experimenting and detective work there, it is good to 
share this stuff to lead to a better understanding of what is going 
on...

My recent observations with a ten week old CFS on an 1280 with VM ink 
are not over yet and I'm waiting another day or two before drawing 
conclusions. I am waiting for ink to dry on a sample I printed 
tonight. It is starting to look like I did indeed have something 
altered in the k ink bottle with the CFS after only 10 weeks- but I 
can't confirm that for another day or two. I do know that if there was 
a change, it was just beginning to happen, and was still very subtle. 
It wouldn't be recognised by a glance at a print. One would have to 
have a stepwedge recently printed and compare it side by side in a 
good light to a sample printed months ago to see the change at 100%k.

So I can easily imagine that I could have left the CFS go for quite 
awhile longer before it really became visually noticable on prints and 
I encounterd the clogging degree that you describe. And my environment 
is arid so perhaps that may also account for time difference of ten 
weeks vs 1 1/2 years.

I remember that with an 1160 and a CIS using the old piezo (Sundance) 
inks, I was one of the discovers and namers of DSS or "the greenies". 
I didn't notice a "density shift" until the CIS had been operational 
for about six months. Now I see that Jon Cone does not reccommend 
using a CIS with the old inks due to evaporation.

It would be ironic if I indeed can confirm there are evaporation 
problems with my CFS and VM ink after only ten weeks of use in my 
climate. Of course there are a lot of "ifs' and "buts" dealing with my 
climate and printer to printer variation I can't account for 
precisely...

Which (1160?) cis and ink set was this, Peter, i.e., was it the CFS 
or NoMoreCarts CIS (possibly rebranded), or another cis? Thanks.

It was a NMC CIS, directly from them when they still sold directly.

Running G4 colour pigs exclusively since new, probably three complete 4 oz 
bottle-sets worth of printing before failure.

I sealed the old CIS with tape, intending to re-use it, but decided not 
to.   When I get keen, I'll take it apart to see what happened.
