My HP Photosmart C7250 won't print because it doesn't detect the other cartridge. It always says that the cartridge is empty. I've followed the instructions on how to clean the heads according to the HP manual. I already replaced the cartridge multiple times.

This printer has been working fine for 6 months and I'm sure I am doing it right. Now I bought a new ink and it says status light that says that the ink cartridge is empty. I don't know if I need to buy a new printer or what.

Any help would be greatly appreciated.

Thank you. ...

Hi guys,

I need some help from you who have wide knowledge in computer troubleshooting.  Last week, I ran the disk de-fragmenter utility of my PC to reorganize the noncontiguous files that I have in my hard drives. While it was running, I received the check disk error and it instructed me to run chkdsk/f.
