IMPORTANT NOTICE Because of possible hazards to an inexperienced person servicing this copier as well as the risk of damage to the copier, Konica Minolta Business Technologies, INC. (hereafter called the KMBT) strongly recommends that all servicing be performed only by KMBT-trained service technicians.
SAFETY AND IMPORTANT WARNING ITEMS SAFETY WARNINGS [1] MODIFICATIONS NOT AUTHORIZED BY KONICA MINOLTA BUSINESS TECHNOLOGIES, INC. Konica Minolta brand copiers are renowned for their high reliability. This reliability is achieved through high-quality design and a solid service network. Copier design is a highly complicated and delicate process where numerous mechanical, physical, and electrical aspects have to be taken into consideration, with the aim of arriving at proper tolerances and safety factors.
SAFETY AND IMPORTANT WARNING ITEMS [2] CHECKPOINTS WHEN PERFORMING ON-SITE SERVICE Konica Minolta brand copiers are extensively tested before shipping, to ensure that all applicable safety standards are met, in order to protect the customer and customer engineer (hereafter called the CE) from the risk of injury. However, in daily use, any electrical equipment may be subject to parts wear and eventual failure. In order to maintain safety and reliability, the CE must perform regular safety checks. 1.

SAFETY AND IMPORTANT WARNING ITEMS SAFETY AND IMPORTANT WARNING ITEMS Read carefully the Safety and Important Warning Items described below to understand them before doing service work. IMPORTANT NOTICE Because of possible hazards to an inexperienced person servicing this copier as well as the risk of damage to the copier, Konica Minolta Business Technologies, INC. (hereafter called the KMBT) strongly recommends that all servicing be performed only by KMBT-trained service technicians.
SAFETY AND IMPORTANT WARNING ITEMS SAFETY WARNINGS [1] MODIFICATIONS NOT AUTHORIZED BY KONICA MINOLTA BUSINESS TECHNOLOGIES, INC. Konica Minolta brand copiers are renowned for their high reliability. This reliability is achieved through high-quality design and a solid service network. Copier design is a highly complicated and delicate process where numerous mechanical, physical, and electrical aspects have to be taken into consideration, with the aim of arriving at proper tolerances and safety factors.
SAFETY AND IMPORTANT WARNING ITEMS [2] CHECKPOINTS WHEN PERFORMING ON-SITE SERVICE Konica Minolta brand copiers are extensively tested before shipping, to ensure that all applicable safety standards are met, in order to protect the customer and customer engineer (hereafter called the CE) from the risk of injury. However, in daily use, any electrical equipment may be subject to parts wear and eventual failure. In order to maintain safety and reliability, the CE must perform regular safety checks. 1.
SAFETY AND IMPORTANT WARNING ITEMS WARNING: Power Plug and Cord • Do not bundle or tie the power cord. Overheating may occur there, leading to a risk of fire. • Check whether dust is collected around the power plug and wall outlet. Using the power plug and wall outlet without removing dust may result in fire. • Do not insert the power plug into the wall outlet with a wet hand. The risk of electric shock exists. • When unplugging the power cord, grasp the plug, not the cable.
SAFETY AND IMPORTANT WARNING ITEMS WARNING: Ground Lead • Pay attention to the point to which the ground lead is connected. Connecting the ground lead to an improper point such as the points listed below results in a risk of explosion and electric shock: a. Gas pipe (A risk of explosion or fire exists.) b. Lightning rod (A risk of electric shock or fire exists.) c. Telephone line ground (A risk of electric shock or fire exists in the case of lightning.) d.
SAFETY AND IMPORTANT WARNING ITEMS CAUTION: Ventilation • The copier generates ozone gas during operation, but it is not sufficient to be harmful to the human body. If a bad smell of ozone is present in the following cases, ventilate the room. a. When the copier is used in a poorly ventilated room b. When taking a lot of copies c. When using multiple copiers at the same time CAUTION: Vibration • When installing the copier, read the Installation Guide thoroughly.
SAFETY AND IMPORTANT WARNING ITEMS DANGER: Work Performed with the Copier Powered • Take every care when servicing with the external cover detached. High-voltage exists around the drum unit. A risk of electric shock exists. WARNING: Safety Checkpoints • Check the exterior and frame for edges, burrs, and other damages. The user or CE may be injured. • Do not allow any metal parts such as clips, staples, and screws to fall into the copier. They can short internal circuits and cause electric shock or fire.
SAFETY AND IMPORTANT WARNING ITEMS WARNING: Safety Checkpoints • After replacing a part to which AC voltage is applied (e.g., optical lamp and fixing lamp), be sure to check the installation state. A risk of fire exists. • Check the interlock switch and actuator for loosening and check whether the interlock functions properly. If the interlock does not function, you may receive an electric shock or be injured when you insert your hand in the copier (e.g., for clearing paper jam).
SAFETY AND IMPORTANT WARNING ITEMS DANGER : HANDLING OF SERVICE MATERIALS • Unplug the power cord from the wall outlet. Drum cleaner (isopropyl alcohol) and roller cleaner (acetone-based) are highly flammable and must be handled with care. A risk of fire exists. • Do not replace the cover or turn the copier ON before any solvent remnants on the cleaned parts have fully evaporated. A risk of fire exists. • Use only a small amount of cleaner at a time and take care not to spill any liquid.
