Question about HP PhotoSmart C4480 All-in-One Printer InkJet

My HP Photosmart C4480 will not turn

I can not get my HP to power on even though it has powered on in the past. I just bought it a few days ago and it was working fine until I tried to turn it on today and it will not respond. It is definately plugged in to a working power source and the electric cord is properly connected to the machine. Any thoughts on how to get it up and running? Thanks!

If you are confident with electronics, remove the rear casing near the power socket, and check the power supply board for a fuse. Using an exact match, replace the fuse and replace the cover. Try powering up. If it fails, you have a blown power supply :(

C4480 all in one screen has an "incompatible print cartridge[s]" message. The same hp cartridges have been in the printer for a month, then 2 days ago get this message

Did any one remove the cartridge to check it, if so will need to initialize it to a used one otherwise check the numbers on the cartridge to ensure none were swapped.

well it sounds like it may be a defect that was undetected since you never used it, unfortunately the manufacturer wont do anything out of warranty.

We just got a Hp model c4480 photosmart printer this past February and have used it just a handful of times. It now displays a paperjam error message with no apparent problem. We have tried to restarting a...

Just remove both the cables power and data from the printer leave it for 5 minutes then re-connect. If it works fine then its ok or else you can conclude that your paper sensor has gone u/s and need to re-install. Before sending for the repair just give power to the printer and take a self diagnostic test to the printer without connecting the data cable to the printer.

New printer not recognized?


Here two causes are possible first your driver that you installed is not insralled properly so turn off your computer, reboot, delete HP Photosmart C4480... driver from the printer list icon and install again properly.(if you will not get the right solution of your problem then try the next step)

Second your U.S.B. cable maybe faulty so change your U.S.B. cable.(if you will not get the right solution of your problem then try the next step)

Third your U.S.B. port of computer is faulty so cahnge the port(many computer have more then one U.S.B. port if you have so try one(if you will not get the right solution of your problem then try the next step)


after this all you try your installation on other machine.

I hope you will get your problem solution.

My Printer won't print and theres no error message.

I had the same problem (I've had the printer for 3 days). I checked my print queue and found that a file from the previous day was too large (1.1MB) I couldn't delete the file so went to HP website. I downloaded a utility file and voila....fixed the issue.
