1 - 3Chapter 1 Troubleshooting1.3 Cautions for Service Operations1) Be sure to remove the power cord except when it is specifically required.If the printer is kept ON, never touch the conductive parts while it is not specificallyrequired.The power switch and inlet of LVPS is live even while the power supply is cut off.Never touch the live parts.2) When checking some parts with covers removed and with the interlock and safety and powerswitches ON, remove the connector (P/J140) on the ROS ASSY except when it is specificallyrequired.When checking some parts with covers removed and with the interlock and safetyand power switches ON, laser beams may be irradiated from the ROS ASSY. Sinceit is dangerous, be sure to remove the connector (P/J140) while it is not required.3) When checking some parts with the left cover removed and power ON, be sure to remove theconnector (P/J31) on the HVPS/MCU while it is not required.When checking some parts with the left cover removed and power ON, high voltagemay be applied by the HVPS. Be sure to remove the connector (P/J31) on the HVPS/MCU.When connecting the connector (P/J31) on the HVPS/MCU according to theinstructions of the FIP, never touch the HVPS and parts of high voltage.4) When using Diag. tools or other tools of high voltage, be sure to keep them covered except whenotherwise specified.When using Diag.Tool or other tools of high voltage, never touch parts of highvoltage.When using Diag. Tool or other tools of high voltage, be sure to follow theprocedure of this manual.5) When operating the driving units using the Diag or other tools, be sure to keep them coveredunless otherwise specified.When operating the driving units using the Diag or other tools, never touch thedriving units. When operating the driving units using Diag or other tools, be sure tofollow the procedures in this manual.6) When touching hot parts, be careful not to get burnt.7) Workers should wear a wrist strap or the like to remove static electricity from their body, groundingtheir body while working.To avoid injury, be sure to remove the wrist strap before working on or near high-voltage power sources, components, or devices.
