Storing Paper

Store paper under the following conditions to maintain quality.

• Inside a cabinet or other dry and dark place
• On a flat surface
• Temperature: 20°C
• Humidity: 50% RH (relative humidity)
  Do not store in the following locations:
• Directly on the floor
• In direct sunlight
• Near the inside of an exterior wall
• On an uneven surface
• Where static electricity may be generated
• In places that are excessively hot or where temperature rapidly changes
• Near a copier, air conditioner, heater, or duct
• Do not unwrap the paper until you are ready to use the paper.
• Do not leave paper unwrapped for a long period. Doing so may result in paper handling and print quality issues.
• Depending on the media you use, usage conditions, and storing conditions, a decrease in paper quality, or curling of the paper may occur.

Maintenance

This chapter explains how to replace consumables and maintenance units, clean the printer, and move or transport the printer.

WARNING

• Do not throw the toner or toner cartridge into the fire. Doing so may cause toner splashes leading to burns.
• Do not keep the toner cartridge in places close to the fire. It may catch fire, which causes fire and burns.
• Do not vacuum spilled toner powder. If vacuuming, it may cause ignition due to the sparks from electric contacts. Toner’s spillage on the floor should be wiped off with wet clothes.

CAUTION

• There are high-temperature parts in the device. Do not touch the periphery of the label “Caution High Temperature”, which may cause burns.
• Keep the toner cartridge out of reach of young children. If young children swallow toner powder, follow the doctor’s directions immediately.
• If toner powder is inhaled, gargle with large amounts of water and move the person to the open area for fresh air. Follow the doctor’s direction if necessary.
• If the toner powder sticks to your skin like your hands, wash it with soap.
• If the toner gets into the eyes, flush with plenty of water immediately. Follow the doctor’s direction if necessary.
• If you swallow toner powder, take large amounts of water to weaken the toner. Follow the doctor’s direction if necessary.
• When handling a paper jam, or replacing the toner cartridge, make sure not to get your cloth and hands dirty. When toner powder stains on your cloth, wash with cold water. If you wash with hot water, the toner may be soaked into the cloth; it may be difficult to clean.
• Do not disassemble the toner cartridge. Toner powder may fly upward, and you may inhale the toner powder or may get your cloth and hands dirty.
• Keep a used toner cartridge in a bag so that the toner powder can not fly upward.
