I’m a Printer Technician and have been working with all types of Printers.I have noticed a eunich problem with HP Deskjet 1220c printers.the problem is you switch it on and the green LED to show the printer is ready only flashes for a few seconds and switches off aand the printer wont print.I’m having problems with a couple of this series i have tried to open it to check the connections to the switch and did not find any problems
