Z6200 - Ink Cartridges Not Recognized ("Missing")

[Pinball-Jerk]

I have begun setup of the Z6200 60" printer and am unable to print even a test page until all ink cartridges are accounted for. Although all cartridges are present, contain adequate levels of ink, and do not show as expired, the printer insists that the Light Cyan, and Red ink cartridges are missing.

So far, I have attempted cleaning the contacts as per HP directions, but to no avail. I am not willing to risk over $600 in new ink cartridges without the promise of that being the solution. 

Barring any other solution, I fear the next step is to remove the left cover and check for loose connections.

Any guidance on how I can better determine what the cause of this issue is will be appreciated to say the least.

Update: Awaiting two new cartridges in the hopes that the cartridges are the issue. I will post another update once these have been tried.

While I have no clue what is your device, I'll try to apply some logic and see if this leads anywhere.

You say "contain adequate levels of ink", is this by checking inks manualy or is this what system reports on your machine?

In order to show level of ink in my understanding it needs to see cartridges.

Also cartridge missing and low or empty ink reports are different things.

I'll assume you know there is ink but machine reports it cannot see cartridges. (If machine reports ink levels but still says no cartridge, do a system reset, factory restore or whatever the name is)

In order for a machine to identify a cartridge it needs a few things.

Cartridge chip, coresponding reading platform, processing board and wires.

You've mentioned cleaning contacts. If you cleaned cartridge contacts, try cleaning coresponding part, unless it is in a shape of pins. However if it is in a shape of pins, check if they are at the same level. No broken pins and/or bent pins.

After Chip and connecting parts are checked and confirmed having no visual defects, there must be a connecting wire/flex cable. It could have a tear. That is unless this is buit in to a cartridge holder, close inspection won't hurt anyway.

Finally, unless you've got spare cartridge holder on hand, check all of the cables going to and from it. Check for bent cable(s), jammed spots etc., reseat connectors. Even a single wire that has been damaged internally, can cause a problem.

All of this is based on me beeing to lazy to look up your machine and seeing exactly how it is made. However, all of the above should give you at least some sort of thinking direction.

The contacts at the end of the ink tubes assembly (where the cartridges make contact) are pretty flimsy and easily bent..I would take LH cover off and have a close look at them.
