Be sure to turn the power switch off and disconnect the power plug before starting disassembly.
• When handling PWBs (printed wiring boards), do not touch parts with bare hands. The PWBs are susceptible to static
charge.
• Do not touch any PWB containing ICs with bare hands or any object prone to static charge.
• Use only the specified parts to replace the fixing unit thermal cutout. Never substitute electric wires, as the printer may
be seriously damaged.
• Use the following circuit testers when measuring voltages:
Hioki 3200
Sanwa MD-180C
Sanwa YX-360TR
Beckman TECH300
Beckman DM45
Beckman 330*
Beckman 3030*
Beckman DM850*
