DesignJet 500/800 Series System error 86:01

System error 86:01 is usually a Carriage Belt failure, or it may just be friction on the Carriage Rail.

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.”

You could try cleaning and lubricating the Carriage Rail. If this does not resolve the error, the Carriage Belt will most likely need replacing.
