• The CPU cooling fan becomes extremely hot during operation. Since touching a high temperature component risks burns, perform replacements after the temperature inside the machine has sufficiently dropped.
  • When replacing the CPU, be sure to replace both the CPU and the CPU cooling fan. When replacing only the CPU, there is a possibility of overheating.
  • When replacing the CPU, make sure that the pins of the CPU socket are not bent. When a pin of the CPU socket is bent, it can cause an operating failure of the print server.
  • Be careful not to damage the motherboard, the CPU, or the CPU socket when replacing the cooling fan.
