Hello, I have owned an r3000 for several years, and have used inkjetmall carts and cone inks since 2014.
I was having intermittent errors “Can’t recognize the following cartridges” with a few different colours. Often removing and replacing the cartridges would clear the errors, but they would often recur, sometimes the same cartridges, sometimes different ones, sometimes in the middle of a print. Refilling and resetting the chips (adding new batteries as needed) would usually help the error to go away, but not always. Often removing/replacing the carts again and again would make it work.
Last month, I couldn’t get the yellow to work, so I ordered a new inkjetmall cartridge, filled it, but it is still not recognized. What’s more, the two cartridges next to it (VLM and LC) are also giving the same “can’t recognize” error. These two were recognized fine earlier today before I installed this new Yellow. I have removed/replaced the cartridges one at a time, and removed/replaced all of them at once after leaving the printer unplugged for half an hour.
I also just received a full set of new large size cartridges for this printer from inkjetmall, but I don’t want to fill them if the printer has a serious service issue. I would love to hear what others think might be the issue here.
Full disclosure: I have twice left the printer for a couple of months without using it or agitating cartridges, but have always been able to recover from this by following the instructions for cleaning wiper, capping station, and running clean/test cycles and doing a bunch of prints to cycle ink through.
There is no visible damage to the chip readers, and the printer was working fine (when I was able to clear the errors by removing/replacing carts) as recently as a few weeks ago.
Any ideas/suggestions would be greatly appreciated!
