HP DeskJet 2720e - information light / ! permantly displaying

[Robbie]

I'm (almost) word for word repeating a question another user asked a few months ago as I'm having exactly the same problem.

[quote]My new 2720e inkjet printer has set up ok and functions as expected.

However there is an "!" on the control panel display and a steady orange light on at the info button.

The HP Smart app tells me every thing is ok.

Can any one explain what the steady orange light means and why there is a ! indicator permanently displaying in the control panel display?[/quote]

Sadly the poster at the above link never returned to answer the questions asked.

The printer is working perfectly fine and if it were not for the above problem I would be perfectly happy with the printer. Is the orange / red information light supposed to be on permanently and the ! symbol permanently dispalying in the control panel display? I'm guessing not as isn't the ! supposed to indicate that there is an error?

This is a new printer, I only set it up a few days ago. It's set up as it should be, I haven't made any changes to it. As for troubleshooting, every check I've made says everything is working normally.

I've found the solution to this problem in another thread that was replied to today. It's because I'm using the ink cartridges that were supplied with the printer but have subscribed to instant ink. One of the cartridges supplied with the printer isn't an instant ink cartridge. Removing that cartridge removes the red light and ! symbol. As my instant ink supplies have now arrived it means that when I insert the cartridges there won't be any red light / ! symbol displaying.
