I got a bad nozzle check with the Matte Black in one of the 3880 after only one week  (The 3880 doesn't clog my foot!).  Only one small bar was visible in that darkest black diagonal area out of maybe 100.

Ran the Unclog routine of Black ink only.  Sadly, it did an ink change to Photo Black since that was the last one I used in the Unclog I guess.  Didn't want to do that.  Big waste of ink.

Had to switch it back to Matte again - another waste of ink.  Still plugged according to the manual Nozzle Check.

Ran a Power Clean (Another big waste of ink), or whatever it is called, and it is starting to flow again.  Ran Unclog again and it is clearing up the clog.

Question:  "Can there be a way for either the Matte or Photo Black ink to be selected from within the Unclog window, rather than flipping back and forth doing ink changes pending how it was set prior?"  QU seems smart enough to know that last ink selected in paper profiles and adjust there, but I'd rather it be done at the Unclog window since once it starts, it can get wasteful.  Couldn't stop the ink switch-out once it started either.

Now I need to go flip it back to Photo Black and see if it is clogged too.  Ugh!

Thanks Terry.

Looks like I got some Set-upping to do.

When running the unclogger in maintenance mode, all ink colors that your printer uses should be selected.  For example, on my Epson R1900, I check all colors and then uncheck blue and green because it doesn't have those inks.  Still, 7 colors are selected so when that pattern prints, very little of each color is used because with a full page print, only 1/7 of the page gets used per color (less actually since it isn't 100% coverage per color).  That is really the minimum amount of ink that should be used to keep the carts primed and clog free.

If a printer (in this case Epson 4800) has these 8 inks: light grey, med grey, black, yellow, light cyn, drk cyan, lt magenta, dk magenta.  How do I map this to the Qimage print unclogger color selections?
Can I selectively run unclog on just one of the 8 Epson inks?

I have upgraded to a version with the print unclogger and was trying to use it last night, but noted that the color selection in the dialog box
(your screen shot above) does not match the 8 colors in the Epson.

OK. I'll try that, but it is not obvious from the instructions/dialog box.
It seems that one can not selectively run the routine on for example just light grey as if one checks the black/grey box it will run the routine on black, med grey and light grey ink.  That is better than running all the inks of course if just one is clogged.

My Qimage PC is not connected to internet so I can't see these videos.  I also learn so much better from written material.

Just an idea, not sure of possible or really all that practical.

I use 17" roll paper and usually before I print I switch to sheet feed and print the Epson test page on 8.5x11 plain paper to ensure all ink channels are unclogged.  I could print the pattern on the 17" roll, but it uses paper which costs more than a single plain sheet.  But it does take a bit of time (and ergonomically not good or easy for me due to my printer location) to switch paper source and sometimes I damage/crinkle/fingerprint the leading edge of roll when re-feeding into printer.

This has me wondering what the smallest/shortest strip of roll paper Qimage could print a head test pattern on?  Maybe if it was short enough I wouldn't always be compelled to switch paper to check.
