I CHANGED ALL THE CARTRIDGES AS ADVISED BY YOUR TECH. What a huge expense to find out this DID nothing!. I suppose now you will advise me to change all the printer heads to the tune of another $100 plus. I would have like a ''right'' response in the first place. perhaps some can tell me the ''real'' problem.

Try This: cold reset on the printer with only the power cable
connected. By doing so, the printer settings will default to factory
settings. Please note that after a cold reset the printer settings will
default to factory settings and you may have to re-configure all the
Press and hold the Return and Select buttons, then press Power button to turn on the printer.

Most likely you left the tape on the new cartridges which protects the printhead. Remove the cartridges, pull the tape off and reinstall the cartridges. If the tape was already off, double check to make sure they are the right cartridges. Good luck!
The hard part is getting to the power supply! The power supply is located at the left side of the printer and in the front (the opposite side of the cartridges).
You have to remove the side and top covers.
There are some hidden screws. One is under the button faceplate that you will also have to remove. The entire procedure is tricky especially without a service manual. Unfortunately I couldn’t locate a manual.
Caution always disconnect the power lines and allow some time for capacitors discharge before you attempt any repairs.
I hope you have some luck with yours !!
