i received a printer from my client with the similar problem..... blinking power light. I tried to disassemble it but was not sucessful. I feel the timing has been disturbed or some other problem.
Hope someone would be able to help me out in this
My pc runs in xp and I had the printer 2 years ago. Actually, my printer is HP Deskjet 3920, not 3915. It was going all well until I started to stop buying and start refilling. Refilling is good... if the printer isn't dumb enough to recognize the cartridge level and self-destruct! I really hate this!
