Question about HP OfficeJet 9120 All-In-One InkJet Printer
My HP 9210 is constantly aligning the printheads. Have to turn it off to make it stop. After I replaced the black ink cartridge this happened. Have never replaced the printheads. The color ink cartridges are expired, but I backdated the machine so they would be okay.
Hi thanks for using fixya!
I recommend that you should replace the printheads to anew one. And you have replace the color ink cartridges as well. If you have used an exprired cartridges, it will result an error to your printhead. Always make sure that you always change the ink cartridges whenever it is required and if you are frequently using it heavily. Backdating the machine is helpful, however it will be more efficiently if you replace the printheads. By the way, how many years now your are using your HP printer? Did you had a chance to send it to any HP Service Center for maintenance as well? I recommend to my clients if they are heavily using or not the machine, it should be always be maintained every 6 months.
If you need further assistance, let me know.
