After a power flicker, my Officejet Pro 8500 wireless, model C023A, is displaying the message,
"The following ink cartridge appears to be missing or damaged
[icons for Cyan, Magenta, Yellow, and Black]
See the device documentation for more information."
And the red exclamation point icon to the left of the Cancel button is flashing.
i am using type 940XL cartridges for all four (4) colors, and have only printed about 150 pages, so it is unlikely that all of the cartridges have gone empty at the same time.
i have tried powering down, as well as downloading and installing "OfficejetPro8500A909g_R1006B_ENG", both with no effect on the message.
The documentation talked about cleaning the printheads, but the reference to an "OK" button is totally confusing. There is no obvious "OK" button on this machine.
Thanks for any assistance.
