Can't uninstall hp series 309a from programs - HP Photosmart Premium C309A All-In-One Printer

No HP Support Assistant is not necessary, it's bloated junk. Uninstall it. Click Start/Programs and look for the HP Support Assistant in the program list to uninstall it. If it is does not have a uninstall feature then Click Start/Control Panel and look for Add or Remove Programs or Program Features or Uninstall a Program. When the list of programs open up, highlight HP Support Assistant then click Uninstall or Remove.

Remove it. Click Start/Control Panel and look for Programs and Features, or Programs (depends on your operating system). Uninstall the HP Support Assistant. It's not needed, just a bloated program on your system.

Try to remove the existing printer driver from your computer. Go to Start > Programs > Lexmark Z2400 Series > Tools > Uninstall. Your computer will then uninstall the Lexmark program. After the uninstall process, reboot pc when prompted.
When your pc turns on, check if your operating system is running on 32-bit or 64-bit. Go to Start > right-click on Computer > click on Properties. Take note of the System Type.
Use the link below to re-install the Lexmark Z2400 Series printer driver: - Lexmark Z2400 Series driver for Windows 7 32-bit - Lexmark Z2400 Series driver for Windows 7 64-bit
Download and execute the file. Simply follow the instructions on your computer screen.
I hope this helps.

Hi

Well it is nothing but to change the region of the printer. hence remove all the cartridges and remove the power supply first.

1. Hold # & 9 key on the keypad
2. Connect the power back to the printer
3. It will say NVRAM init.
4. It will ask for the Region select what you want.
5. And continue to work

OR

Goto setup menu in printer and change the region.

Regards

run hp print diagnostic utility http://h10025.www1.hp.com/ewfrf/wc/document?docname=c02072599&cc=us&lc=en&dlc=en&product=421991&tmp_track_link=ot_search
instructions on how to run it are included in that link.
if it does not fix your problem I strongly suggest you uninstall the hp printer software from your computer and reinstall it.if you still have the cd installer,insert it in the cd drive and select uninstall.if you do not have the disk uninstall it using add/remove (win xp) features or programs and features (for vista or win 7).make sure to uninstall all hp programs associated with your officejet 6210 (driver series,hp customer participation program,imaging device functions,shop for hp supplies,hp yahoo toolbar,hp image zone.hp memories disc,hp update,hp smart web printing,hp photosmart essentials). NOTE:uninstall programs enumerated above only when you have that printer installed on your pc because uninstalling them may affect the functionalities of other printers installed on your computer. handle is invalid error is caused by a dll file that got corrupted. after the uninstall,restart pc. then reinstall using the same cd or better yet download the latest version of software. here's the link for that.

Solved! I now can scan wirelessly throughout my network. I downloaded the drivers for a friends newer HP all-in-one scanner and I can scan. Look for the driver for the 309a series of printers and install it. Complete the install and set up your existing printer. You can now scan, print, fax wirelessly. It includes updated HP apps for these functions that work with OS 10.5. I didn't upgrade to the HP 1.1 drivers through Apple. The file name is: PS_AIO_05_C309a_Net_Full_Mac_WW_102.dmg

Yes it is.
I had the same problem with the 1300 series.
Uninstalling it from Add/Remove programs and then reinstalling it had the same problem. i had to uninstall it from the program directory, delete the program directory then do Add/remove programs and then reinstall it to get the Solution center and HP Director icons.
