Question about HP DeskJet 3940 InkJet Photo Printer
I have a HP 3940, which I have had for about a year. I have had a couple of sets of cartridges during that time. In each case these were HP cartridges and I have had no problems with the printer to date.
When the last set ran out I purchsed remanufactured cartridges from a reputable retailer. When I installed these I was unable to print and had an error message "HP Deskjet not connected". I have uninstalled and re-installed the printer but this has not solved the problem.
When I reinstalled the printer with the old (HP) cartridges installed the printer printed OK. It also did so after shutting down and restarting my PC. However, when I last started my PC (with the old HP cartridges installed) the "not connected" error message reappeared. My operating system is ME. Any suggestions would be appreciated. Wayne.
The "remanufactured" cartridges can cause the printer to stop working by making a electric failure in the printer circuits. Those cartridges should be avoided now that HP makes extremely cheap and fragile circuits, not like the cartridge burner's HP's 600, 700, 800.
