Officejet Pro 8100 cartridge icon blinks

[Beach_Bum]

The printer worked as advertised (using USB cable) until black ink cartridge needed replacement. THREE new cartridges failed to restore former working condition - the black ink cartridge icon lite blinks repeatedly which prevents printing. I've tried both USB and wireless connection without success. Also ran "print & scan doctor" and "easy setup" REPEATEDLY also without success. Download printer driver(s). Finally removed and reinserted the print-head (cartridge holder) but lite continues to blink. Can this situation be corrected by a poor but honest user like me ??

ADDITIONAL BUG - UNABLE TO UPDATE FIRMWARE.  Desperately trying anything & everything to salvage the printer but apparently the blinking icon cartridge lite prevents proper troubleshooting. It's beginning to appear that merely replacing a black ink HP cartridge could result in scrapping the printer.

Factory reset procedure is no help either. Why is this happening to a nice guy like me ??

STILL MORE - following link says that HP firmware may be cause of initial rejection of 2 of 3 replacement cartridges but fails to say how to remove firmware.  It's worth a try but HOW ??

Hi @Beach_Bum,

I'd like to help!

As this is a hardware issue, I'd suggest you contact HP support in your region regarding the service options for your printer

Follow the instructions below to reach them:

1) Click on this link - https://support.hp.com/us-en/contact-hp

4) Select the country from the drop-down. 

5) Select the chat or get phone number options based on your preferences. 

6)Fill the web-form and proceed further.

If you are having trouble navigating through the above options, it's most likely because the device is out of warranty. If yes? please send me a private message with the region you are contacting us from. Check next to your profile name, you should see a little blue envelope, please click on it.

Another HP printer (officejet 8620) has been discontinued by HP and is reported NOT to accept newer ink cartridges with correct model #s (950 & 951). Is it possible that same fate has happened to my 8100 Pro since nothing that I've tried so far restores prtr to normal functions ??
