0x61011beb ink system failure on my HP officejet 6500. I have gone through all the troubleshooting steps = not fixed. Makes a clicking sound when it reaches the r-hand side. It is still under warranty, but we need to fix it ASAP. No paper jams, carriage moves freely, hard reset done several times to no avail.

1. Plug it directly into the wall, rather than into a UPS
2. Verify that the unit is switched on. Disconnect the USB/Ethernet cable from the All-in-One and also disconnect power cable from All-in-One and also from wall outlet.
3. Wait 30 seconds.
4. Plug in the power cable to All-in-One and also to wall outlet.
5. Check for the functionality.

I still had the error message, so they said to reset the printer to factory default settings:
1. Unplug the power cable from printer when the printer is powered on and wait for 20 seconds.
2. Then, press and hold # and 6 while plugging in the power cord.
Continue holding until it displays Semi Full Reset message in the front panel of the All-in-One.

If those two steps do not resolve the problem then its is hardware related and can't be solved here.

Try this fix, it worked for us a few times:
