My problem is slightly different. My PK chip was telling me that there is ink in the cartridge about 1/8 full when the cartridge was actually empty. I kept printing with the empty cartridge now the black ink is not printing. I have tried multiple cleanings and printing of test sheets after refilling the cartridge and the black PK is not printing. It seems to have lost its prime. The cartridge chip did not reset to full when I refilled it it still reads about 1/8 full as it did when it was empty.
This is the first time I have used up the PK cartridge since going to the new ink system. And yes I filled up all cartridges completely as per instructions when I started.
Two weeks ago I took the cartridges out to shake them up as per instructions and replaced them. This did not affect any of the ink cartridge chip readings to the printer and the printer worked fine afterwards.
I have been very happy with the Con inks. The colors are just as good as original ink colors as far as I can tell. The printer has been working fine until it ran out of the PK Ink.
Any help would be greatly appreciated.
Thanks, Larry Carnes
