The jamming was caused by a malfunctioning paper detector. This part had to be replaced. After the repairman installed the new part, he called to tell me that all of the ink lights were now on, and that he couldn't test the repair because the printer wouldn't function. Since I've had the same experience of having all the ink lights come on, I told him to simply pull out each cartridge and reinsert them. He said he did, and that didn't correct the issue. He also told me that some of the cartridges were almost empty. So, I assumed that by making sure all of the cartridges were full, the ink lights would go out and the printer would function again.
When I got it home, I filled the low cartridges and fired the printer up again. All of the ink lights came on. In checking the printer utility, I get the message that none of the cartridges are being recognized.
I don't have a chip re-setter. Will re-setting the chips correct the problem, or do I need to do something else?
