I have a 4900 that I had fllshed with the flushing fluid. It had some nasty clogs, but it eventually got working. a nozel check whowed all pink.
BUT, I was running out f flsh in several.
I switched to the thrift ink pro, and did a charge ink nd a nozel check. About half of the nozels printed, everything else was blank. not even pink.
So I did a second flush, and everyone printed some. Tow were iffy and the black was not working to print the names of the colors.
So, I did the option to purge the lines, thiking that it would use less ink. and now nothing is working…
I checked the lines, and they have ink. One has a few bubles… so that needs to be addressed.
Does purge lies actually empty them, or does it do the same as an initial fill, with less ink?
I will do an initial charge again, and see if it helps.
