For the Error "140B" that you are getting I suggest you can:
-remove the ink from the printer then power it off.
-then using a Q-Tip with cleaning alcohol (or warm water if you do not have any), clean out the chip of the cartridge and areas where the ink goes in.
-Then use a damp cloth and wipe down the inside of the printer.
-Once done, let it dry for 10 minutes
-Then put the ink back in, power it on and tell me if it then prints correctly please
PLEASE NOTE: do not touch the chip of the cartridge with bare hands as may damage the chip.
