I have a newer Designjet 510 42" and I got the 5:10 error. Also the formatter card had the red light on. I found one at a local shop. They pulled it out of a designjet 500. They told me it would work and after looking online I have found some saying it would.
After installing the new card the printer boots up to the System Error 5:09 screen
Could the issue be as simple as the card is not compatable with our 510 or does it sound like the printer itself is FUBAR.
The card I installed has the amber light flashing.
