My hp officejet pro 6830 suddenly quit printing black, can see ghost letters on paper but no black ink. Test page show color but no black. Replaced all 4 ink cartridges that cost me $80 thinking this was the issue. Went through all the troubleshooting hoops such as cleaning print heads...no luck. If I can't resolve this issue I will be shopping for another printer and it won't be an HP. Very frustrating.

@trmaret, Welcome to the HP Support Community!
That's unfortunate. Let us try these steps:
Reset the printer
- With the printer turned on, disconnect the power cord from the rear of the printer.
- Wait at least 60 seconds.
- Reconnect the power cord to the rear of the printer.
- Turn ON the printer, if it does not automatically turn on.
- Wait until the printer is idle and silent before you proceed.
Note: HP recommends connecting the printer directly to a wall outlet rather than a surge protector or a power strip.
