When I get a clogged nozzle on my 1430, rather than running a cleaning cycle, I use QTR to purge only the channel I want to target.
So if, for example, my K channel is clogged, I use the “PURGE K” QTR profile, and then print a page of large black text. It will start out with some line breaks in the text due to the clogs, but once the ink gets flowing, they usually clear right up. The advantage of this technique is that you are only purging one channel, not wasting ink in every channel, which you would be doing running a QTR calibration page or Epson cleaning cycle.
You can do this with any channel using the attached profiles.
I’ve posted my 1430 profiles here. Just add them to the 1400/1430 folder in QTR and install as usual. It’s very easy to modify these for any printer.
Hope that helps.
