Digital BW, The Print

Gary,

The Epson OEM carts have always got the ink flowing again when I've used them 
for stubborn clogs. My success before being advised about their strong medicinal 
was not very good:  I replaced an 1160 printhead every 9 or 10 months for a couple 
of years. After replacing the bad cart with Eps OEM, I often get a perfect nozzle 
check after one cleaning cycle; and the tougher clogs have all yielded to the 
Eps OEM carts after letting them sit in the printer overnight.

Whenever I do 3 cleaning cycles, I print a purge-pattern (downloaded from MIS's site).
If the problem is only with the black, I edit out the color columns so I don't waste ink; 
if the problem is with the color cart, I remove the black column.

Hope this helps.
John

  Jim,

  I searched the archives and distilled information from the many posts 
  to the list on clearing clogs using various windex and paper towel 
  techniques.  Over the weekend I tried these and on Sunday evening 
  tried the printer again -- still no luck, the black nozzles are still 
  partially clogged resulting in very noticeable banding.

  Specifically, the left most black grid on top is mostly there, with 
  just a few gaps showing up here and there.  The black grid on the top 
  right is the one that has been the worst and gotten worse over time.  
  Lots of gaps, not always in the same place after a cleaning cycle.  
  The three grids below from the color positions have always printed 
  out perfectly.

  So, since the windex and paper towel techniques did not work for me, 
  I'm wondering what to try next.  The windex direct injection as 
  described on the MIS website?  I've thought about pulling both of the 
  cartridges and putting in Epson OEM cartridges for awhile (read 
  something about the Epson inks being good for clearing air bubbles).  
  Or purchasing some cleaning cartridges from MIS and running those for 
  awhile before installing new cartridges.

  Any suggestions?  I sure would like to get back to making prints 
  again.

Yes, this many of the time is the next step, but I wanted more info on 
nozzle appearance before I recommended it myself. 

Since the right-most grid is the worst offender, and it doesn't jump 
around to other areas, I think we can rule out air bubbles or a 
misfilled cart. Your nozzle check seems to be speaking CLOG. You do 
hint at getting more spaces moving around after a cleaning cycle; if 
you also get MORE spaces opening up than before the cleaning cycle 
this is a sign that you are doing more cleaning cycles than the 
printer wants you to- even if it only three.

  The single most important thing to do now is get Epson carts in 
there as quickly as possible. John's method below I'd pretty much 
agree with and he sounds experienced in these things; you don't need 
to edit out the other colors for the purge sheets though as MIS has 
individual color purge files that print  pretty much the whole area 
black, or cyan, etc. I'd run maybe between 3 and 7 pugrge patterns 
every day depending on whether single color or full color narrow 
stripes for three days or so, and then try the 3rd party again.

I would make sure of one other thing: be sure the parking pad has the 
springs under it (push gently with finger and that will tell you), 
that the pad has not dried out, and that the rubber rim of the pad is 
cleaned off with a foam swab (Radio shack) dipped in something like 
40%ethanol-60% distilled water or the old stanby-windex. Be carefull 
not to drip outside the pad. Putting a couple of drops of the stuff on 
the pad before shutting off with either Epson carts or 3rd part inks 
in is a good idea- don't overdo it, once a week or thereabouts.

 If this doesn't do it, most people try the direct injection method, 
and/or after that point pay Epson tech for a new printhead swap. Since 
special software is used to align the new head, be sure a "real" Epson 
place swaps it, although a few I guess have gotton away without the 
"alignments" to report it still prints okay..
