System error 21:10 is usually a Service Station failure. Error 21:10 may be seen on the LCD display of the following models: DesignJet 500, DesignJet 510 and DesignJet 800.
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 HP DesignJet 500/800 Series Service Station Assembly C7769-60374 will most likely need replacing. You can buy this genuine HP C7769-60374 from Rightparts and use your own engineer, or we can replace it on-site in under an hour. Please email for a quotation.
