• Code: E609-0008
• Description: There is an error on the HDD.
  At startup, the HDD fails to reach a specific temperature level within a specific period of time.
• Remedy: Replace the hard disk. Replace the DC controller PCB.

• Code: E609-0009
• Description: There is an error on the HDD.
  At time of sleep recovery, the temperature fails to reach a specific level.
• Remedy: Replace the hard disk. Replace the DC controller PCB.

• Code: E610
• Description: The HDD coding key is faulty.
  The SRM/PCB is faulty. The battery has become exhausted, leading to loss of SRAM contents.
• Remedy: Try step 1); if it fails, try step 2). 1) Turn off and then back on the power switch to generate the key once again. 2) If the same error still continues, replace the board on which the SRAM is mounted. (Keep in mind that doing so will lead to loss of all user data.)

• Code: E674-0001
• Description: An error has occurred in communication between the fax control PCB (2-line) and main controller PCB.
