HP 25500 black cuts out intermittently

[Andy D]

I'm new to this printer and I'm not sure what the known issues are for this model.
Once the black starts printing correctly it seems to do fine, but sometimes
if I let the printer sit for a minute between prints, the black cuts out, sometime
it will print fine, even if it sat over the weekend.
We replaced the print heads, any suggestions of what we should check next?

Thanks

Is the cartridge nearly empty?
