Designjet 510 - issues with black printing

HP Recommended
Designjet 510
Microsoft Windows 10 (64-bit)

Hello 🙂


I was just given an HP Designjet 510.

It hasn't been used in a while (not sure if it's been a few months - may even be more than a year).

I've set it up, and can print to it, but the black missed spots.

It's reporting that the ink and print heads are fine.

I assume I need to do some kind of 'Clean print heads' but can't find where.

When I do a 'troubleshooting' - it prints the Diagnostics Print A.

In the top row, the Yellow, Cyan Magenta print perfect - black prints pretty good.

In the next row, the colours looks good, but the black starts out light and fades to nothing right away.

It's like the black is running out - shows as 29%.

Any suggestions?


Thanks in advance 🙂

DJ510 is a good printer, invest in the new black printhead C4810A and replace it.
