I have purchase an HP combo pack 74-75 that both were rejected by my printer. Returned and replaced with New HP 74-75 combo pack that the printer accepted. Printed about a dozen pages and then the printer errors out various displays that the cartridge on the right is not intended for this printer or insert cartridge on the right. I have performed all the maintenance cleaning from this site. These products were shipped in the last 2 weeks. Is HP having problems with a current run of ink products?
