I have a HP 4100 DTN that is not working. It was purchased in 2002, but the page count has to be below 140,000. When the Ethernet card, all extra trays, extra memory, and the duplex unit are removed, so that it is effectively a HP 4100 the printer display still shows all asterisks "*******". When I change the memory that is installed, the display does properly dsplay the amount of memory that is installed, then switches to all asterisks. None of the LED's on the front panel light. What should I replace?
