Designjet 500/800 Series System error 21:10

System error 21:10 is usually a Service Station failure.

The first thing you could try is “Turn the printer off and allow a few minutes for printer to cool, then turn the printer back on again.”

If this does not resolve the error, the C7769-60374 HP DesignJet 500/800 Series Service Station Assembly will most likely need replacing. You can buy this genuine HP part from Rightparts and use your own engineer, or we can replace it on-site in under an hour. Please email for a quotation.
