None of the steps worked for my hp 79 service error. I took the printer to a local printer repair store and got it serviced. It is very expensive to repair hp printers, just as high as their ink price

Hp is really doing a great job. They manufacture printer that is filled with errors (like 79 service error i have) which has no fix so that they can drain more money from us for fixing it. I paid a lot for this printer and their ink cartridges are very expensive and now i have to pay almost the half amount of what i paid for the printer to get it fix. Well played HP, never going to purchase any hp product from here on

It did not work for me. I have tried everything available on the internet for 79 service error and none of them provided anything that could solve this problem, this printer is old and has no warranty, so i got no support from the hp technical support. now i have to take it to a local printer shop to get it serviced.

Switch off the printer, remove all the cables connected to the printer, press the power button for few seconds and reconnect the cables and power up the the printer and 79 service error will be gone. Thats how i fixed the error message on my hp printer.
