The amber RM10 and RM11 light is flashing on my karcher 7/10

Hi, on most Dells a flashing amber light on the power button indicates a problem with the PSU or a short on the main power rail, if this is the case you should have 2 flashing lights as well, 1 & 3.

If the wireles light is flashing Amber .. Some one outside your house is trying to access the Wireless network . If it is always flashing amber.. try with a Firmware update available in belkin.com/au/support.

Thank You

when i turn the printer on the light flashes amber several times, then green then repeats flashing amber, and back to green etc. turning it off and back on made no difference. last time it worked normally after being off for a couple of days, but now it is doing that again.

Amber light flashes 7 times, then green for a couple of seconds, then amber 7 times etc.

what error message coming from your computer...i think something stuck inside your printer

Hi:
This sounds like a short circuit or motor problem. They are relatively easy to take apart. If you see a burned wire or connector this can be repaired. If not, it is the motor and probably too expensive to repair considering the price of a new one.

4 blinks of the amber light says that the ink is empty, at least 1 cartridge is empty.

The Battery indicator LED is to the right of the power LED. Flashing AMBER indicates a fault with the Battery. To resolve, replace the system battery.

You do 2 things. See the service manual

I believe that 7 amber flashes refer to a cartridge error. Check that the cartridge is seated correctly.
