Question about HP Photosmart 8450 InkJet Printer

1 Answer

Dead printer My hp photosmart 8450 printer has only been used about 5 times over the last 6 months but has now stopped working completely. All I get is a flashing red light from the card slot area and an error message on the central small colour screen C0620003. Any help here would be greatly appreciated.

    After using for about 2 years, I was using when it make a "popping" sound and went dead. Now when left unplugged for a few minutes, then plugged in it comes on for about 3 seconds then goes completely dead again.

I am afraid this is a fairly fatal error. It can sometimes be recovered in one of two ways: 1) Unplug the unit for at least 24hrs and once unplugged press all the buttons at the same time for a couple of seconds. Leave the unit alone. After 24 hrs or so plug it in and try again. Chances are it will be the same 2) Flash the firmware with either the same or updated version. This would require a copy of the service utility and latest firmware to upload. VERY hard to get hold of either. A final chance may be to get a second printer with say a broken head and pinch the main board from that to repair your own.

Where can I get a windows 10 driver for HP8450 photosmart printer


Most HP drivers are available here: http://support.hp.com/us-en/drivers . Then search for your model. The direct link to the drivers for the Photosmart 8450 is http://support.hp.com/us-en/drivers/selfservice/hp-photosmart-8400-printer-series/402149/model/402151#Z7_3054ICK0K8UDA0AQC11TA930C7 . Select your OS version.

The Photosmart 8450 drivers should be found with the new hardware wizard in Windows 10. You'll need to connect the printer to the computer via a USB cable to start. (Make sure that the system is connected to the internet.)

I hope this helps.

I am using a stand alone photosmart 8450 ( with out computer ) it will print every memory card except SDHC the cards are fine as I use them in my Pentax camera


The 8450 works with SD cards. While SDHC cards will fit into the slot, they are electronically incompatible and will not work in devices not designed for them. SD cards will work in SD and SDHC devices, but SDHC cards will not work in SD devices.

My scanner stopped working. hp solution center says that the device installation is not complete. i have a hp photosmart 3210 all in one. it was working the last time i used the scanner.


You probably need to uninstall and re-install the Latest Drivers for your printer

To uninstall you can do it from the Software disk you recieved with printer.
Insert the Disk in CD ROM and Click uninstall from HP Printer Menu

OR If you dont have the disk, you need to manually uninstall the Software
( Disconnect the USB cord before uninstalling )

Click START - Open Control panel - Add/remove Programs ( XP ) / Or Programs and FEatures ( Vista/Win 7 )
you will find list of HP Programs installed..

Choose one by one and uninstall these programs
1. HP Customer participation program
2. HP Imaging Device and software
3. Software and drivers for Photosmart 3200
4. HP Solution Center or HP Director
5. HP Image Zone ( or Image Zone Express / HP Photosmart Essential )
6. HP Update
7. HP Printer Drivers/Diagnostic Drivers
( after every Uninstall you will be prompted to restart the PC, you will find an option [ Click here to restart later ]. click on it and restart the PC once you completed uninstalling all the above programs )

Once you have uninstalled - click on this link to download the latest drivers by choosing your operating system

My HP Photomart 8450 prints in black sporadically.


Normal 0 Driver could be corrupt.
Normal 0 Disconnect the printer or at least be sure it is turned off. I'd do both and reinstall the CD software program that came with the printer. When the software program asks you to connect the printer to the USB port, do so and it should again work properly.
Hope this helps. Bud
