Check in bottom of the ink cartidge u must have to remove plastic strip.then also check u proper fixed ink cartridge in ink tank as matching color.
re-seating the cartridge may temporarily fix the problem but it will not last. but if even that doesnt give u relief.... then its a hardware failure and wud service is required at this point. contact Hp...

thank you for using Fixya...
have a nice day

Alarm light is lit -


Ok my printer is giving me the U140 message saying that ink tank cannot be recognized. The new ink tank is Cannon (not a off brand or refill). i think it is a problem with the chip reader port inside the printer not the ink tank chip. I feel this way because if you switch around the yellow and black 8 tanks, the printer accepts them without error.. soo if it was the ink cartridge i could be able to swap the black with the magenta and it should read it.
