I have an HP OfficeJet Pro 8025e. I just changed my black ink cartridge (using an Original HP ink cartridge) and now my printer has been stuck saying "validating - please wait" for hours. I unplugged the power cable from both ends, waited a couple of minutes and then plugged it back in and it still sits at "validating - please wait." I also tried reseating the cartridge. Any suggestions?
