Hi, fellows,
A customer has an hp-ljc-2840. It asked for a new black-Crtdg and the customer installed a brand new OEM one; but it does not detect it and keeps on asking for a new K-Crtdg. The customer figured that the cartridge was possibly defective and had it replaced for a second new OEM black cartridge. But, low-and-behold! it still does NOT detect this second new one either.
I have checked the sensors but cannot find anything wrong. The other cartridges have not problems.
What could be wrong? Please help.
