I have been noticing quite a few complaints of this type of late. A
person changes several cartridge at the same time or within a small
duration of time, and they lose a complete color or more.
I am beginning to suspect a few possibilities.
1) Perhaps exchanging several cartridges at once, is more than the
vacuum pump can handle in reinitiating the ink flow
2) Perhaps the cleaning/purging station is not providing a full seal and
therefore the vacuum is not complete.
I suggest trying the following, with the following caveats:
IF YOU ARE NOT COMFORTABLE WORKING ON YOUR PRINTER, GET IT
PROFESSIONALLY CLEANED OR REPAIRED. I CANNOT AND I WILL NOT TAKE ANY
RESPONSIBILITY FOR DAMAGE DONE TO YOUR PRINTER, OTHER PROPERTY OR YOUR
HEALTH OR WELL-BEING AS A RESULT OF ATTEMPTING ANYTHING I SUGGEST IN
THIS POSTING, WHETHER DUE TO MISUNDERSTANDING OF THE INSTRUCTIONS OR
IMPLEMENTING THEM EXACTLY AS INDICATED. YOU TAKE ANY ACTION UPON YOUR
PRINTER AT YOUR OWN RISK.
Get some ammoniated window cleaner (typically, the blue stuff that
smells like ammonia).
Remove each cartridge which isn't working, and drop a couple of drops
into the ink outlet of the cartridges (the place that was punctured by
the ink nipple) and a drop or two on the ink nipple tip itself, and then
return the cartridges. Make sure they are fully seated in their slots.
Start the printer and run one or two cleaning cycles if the printer
doesn't initiate them when you start the printer. Then try a nozzle
test and see if you are showing the steplike pattern for each color. If
the test is not showing complete steps, run one or two more cleaning
cycles, which should take care of it.
If this fails to work, your next step is to try to get the vacuum pump
and cleaning/purging station to work and seal against the head well.
If you know how to unlock the heads and move the head unit over out of
the way of the cleaning station with the printer off, do so. If not,
turn on the printer and start a printing job, and unplug the electrical
cord for the printer while the printer is away from the cleaning
station, so it is exposed. With an eyedropper, fill the cleaning
station with the same ammoniated window cleaner solution and return the
printhead to the station. Allow it to sit for a fee hours like that, and
then turn the printer on and allow it to do a purging or cleaning
process. If it doesn't do so, run two cleaning cycles. Run a nozzle test.
Hopefully, now you have all colors printing. If not, request my Epson
Cleaning Manual, as you may have developed under head ink build up.
