George, This is the same problem I was having with the cartridges & I contacted the company I bought the printer from. Luckily they were not too far away from where I live & they asked if I could take the printer to them to have a look to see what was going wrong. They tried various different things but in the end they decided to change the chips & hey presto it was working. It was ok for a short time & then the same happened again & again. Talking to other printer & cartridge suppliers it was evident that this was quite a common problem on the D120. As I said before I finished up having several sets of chips in stock & replaced them on a very regular basis. In the end the same explaination started to come from suppliers that it seemed the extra black cartridge seemed to be causing the problem. Now I know this bit will seem a bit silly but, it's what I was told time & time again. It seemed the chips in the two black cartridges seem to have a conflict all of a sudden & would in a way argue between them who was the dominant black cartridge to the point neither of them would play with the other. Like I said sounds really silly but, it did seem to be the case. I think the proof in point here is that the D120 was soon replaced when all these similar problems arose & the replacemt didn't have that extra black cartridge.Georgestreets;19458 wrote:The other night I managed to get a 1/4 of the page printed then it just stops and the red light comes on.
I know they'll probably be a few posts dimissing what I have said but it did happen to me & I've just repeated what was said to me by suppliers who were having a nightmare with this printer.
