HP C7280 Ink System Failure

Here are the details. Got the Ink System Failure message. The error code shows was '0xc18a0005'. The tech had me press and hold the '*' key on the key pad, then press the '#' key and release them both. Then he had me enter '123' to enter maintenance mode. He then had me press the right arrow (beside the OK button) until System Config. menu appeared on panel. Then pressed OK two times to clear the error condition, then cancel two or three times to return to the top menu. Then powered off and back on, printed a test page just fine, copied a document fine.

After seeing the hitting the buttons with the door open tricks for different models I tried anything that sounded like it had the same buttons my 4040 has... nothing on here worked so I just started hitting combinations of buttons with the door open - wow there are quite a few hidden menus there

For the toner life reset menu:
1 Open the front cover of the printer
2 press and hold the cancel button
3 press the reprint button while still holding cancel
- here is the reset menu - go to the appropriate cartridge on
- the menu and reset it and you're done!
FYI... Pressing the "Go" button and the up arrow gives you the parts life reset menu (drum, laser, fuser, etc.)

Brother MFC 9440CN Toner Life End Message

Brother toner cartridge low toner override

There is a "flag gear" that, it seems, slowly turns (counterclockwise) as the toner cartridge is used, which finally hits a stop that appears to force the toner light on and prevent printing even if there is toner left. I have a TN550 cartridge which was refusing to print, and indeed the gear was at the stopping point. To reset the gear, take the cartridge out. On the gear side take off 2 screws, the flag gear (on the tn550) is the black gear on top right side, with a small spring underneath. Just take it off and reset it (rotate clockwise) so it is not at the stopping point.
