21.13 - HP Designjet T1100ps Printer

The 21:13 error is a service station jam error. My recommendation is to replace the service station with a new one. We have tried many times to fix these by cleaning and lubricating and the error will still persist for no apparent reason. If someone is successful at fixing these, I would like to know how. Bob Wert
