Printer trouble (by 11 users)

When I try to print on my HP Photosmart C5280 all the lights flash and error code 00C515C4 comes up, everything freezes and I can't even turn it off, I have to unplug it. It was only installed and used last Friday

how do you correct this error??? 00c515c4 on my hp 5280 all in one printer?

Have an error on my HP C5340 printer 00C515C4. All the lights flash on it and my printer won't work.

Hi I have the same problem with my HP Photosmart C5280

All the light are flashing and the screens states that I should turn the printer off and on. When I hit the off switch it just doesn't stay off but immediately restarts and when I do this I very briefly see an error message "error 074a4dd6"

On my PC it continously tries to reinstall the printer and gives a fatal error. I have unplugged the printer completey and taken the power off but appears to have gone the way of the Dodo! I am going to completely deinstall the printer this weekend to at least be able to work on my PC. My Wireless connection has also deceased on my PC but it still works on my laptop. Unfortunately I can't fix that problem because of the printer installation error!

Kind regards

Fred
