getting flashing light on power and problem light when pressing the scan button. serial no. cn94b220w7 tried help doctor it said i needed to down load a large file,also said it would be better to get the cd disk
Running the HP Print and Scan Doctor app is really the best way to diagnose connection problems and you will have to download that to get the latest version (i.e., v5.0) and run it. There's really no way around that.
Also, once that runs, it might also require that you download additional diagnostic routines..
And finally, if it determines you need new drivers, it will ask to download the latest printer drivers, as well.
If you don't download and run these, you won't be able to diagnose and fix the problems
