I have the same problem with a refurbished printer. The guage was always white for all. I did not know if white was full or black was full. By the time I found out white meant empty the warrantee expired! I spent many hours exchanging emails with HP support. Each time I got a different tech. Each time they did not review the previous emails (that were included) and asked the same questions/had the same suggestions. I sent diagnostic print outs showing good prints with 0% ink in the cartridges. I replaced some of them (with genuine HP) and got the same result.

After reading this thread I tried the reset (help & OK) most of the color cartridges showed ink. The one that did not I replaced with another new HP cartridge. It showed as 100% full. The black still showed empty.

I tried checking it from the printer software on my desktop. It showed empty cartridges (this time all black - inconsistent to the printer display)). I read elsewhere that you need to install the printer to the USB port where the ink levels show - I tried that and 2 color cartidges showed ink. Then I swapped the port on that set-up to be the LAN port and they showed up. That worked until I re-booted. 

I removed the black, cleaned the contacts replaced it - it still showed empty. I re-reset hoping it would show the black. After that it went back to showing ink in only 2 color cartridges. The test print still looks perfect except for reporting 0% ink in all except the 2 cartridges.

I am suspecting leaks around the O-rings on the cartridges. Does anyone know how these cartridges work? Is that a possibility?

I have HP computers, laptops, printers that have worked well over the years but this printer is causing me to loose faith in HP. It is very disconcerting that the technical support seems un-aware of these problems and the fixes especially as they are reported on the HP support forums.

Anyone have other suggestions on resolving this apart from buying a competitors product?.

Try Stewml's solution on the previous page. Yout problems sound the same as the one I had. I tried EVERYTHING. Stewml's solution worked and I haven't had any problems since. It has nothing to do with O rings. I believe when they refurbished these machines they forgot to do a full reset--that would explain why many of these machines have the same problem.

Another possibility: When I got my 7280, I transferred partially used cartridges from a different HP printer that used the same ones. Later I read that the cartridges that come with the printer are supposed to be used because they somehow are part of the initialization process. If that is the case, HP doesn't make that clear enough in the installation instructions.

An update on my 7280 printer problem

I fixed the problems about 6 months ago when HP came out with an updated printer program. It shows the ink levels correctly now. 

The only problem I have with it now is that when I print 2 sided the software pops up with a message that  the unit does not have the Automatic Two-Sided Printing Accessory installed. It does have it. If I use the web browser to check it the device information says that it is installed. The program says it will print 1 sided. I select the OK button and it prints 2 sided!

Heres a good one for everyone.

I struggled with the level indicating low and went and bought new cartridges like I imagine many have done. Same result with the "new" HP branded cartridges. I say new because they came as a kit, in a single HP box.

Something popped in to my head to weigh the old and new cartridges with the digital scale I have that is capable of weighing very low numbers.

Much to my chagrin, it would appear that at least two of the NEW cartridges are EMPTY, fresh out of the HP box.

There is a reasonable difference to the new and old cartridges weights on the NEW vs. OLD that I am assuming are full vs. empty to make me believe that the offending cartridges, while bought as new, are EMPTY.

I had inadvertantly printed a huge color document that I am perfectly accepting of the fact that I used up the ink in the original cartridges. So, I weighed the cartridges that were saying empty, then weighed the new full cartridges of the same color and in two instances they weigh the same. The other cartridges have a few gram difference.
