Probably your papers moisturize due to high humidity. Take care of how you store the papers; ensure that no unused paper is left in the cassettes, but put back in the wrapper at the end of the working day. This is just one of the simple solutions, but you could as well turn the 'humidifier circuits 'ON', Assuming the machine has this features fitted. Refer to the manuals.

iR2318

Operating environment (temperature range) 15 to 27.5 deg C
Operating environment (humidity range) 25% to 75%
Operating environment (atmospheric pressure) 0.6 to 1.0 atm

there are no Magic Adjustments in poor environments

Avoid locations subject to temperature and humidity extremes, whether low or high.
For example, avoid installing the machine near water faucets, hot water heaters, humidifiers, air conditioners, heaters or stoves.

Avoid installing the machine in direct sunlight.Avoid exposing the machine to rapid changes in temperature.
If the room in which the machine is installed is cold but rapidly heated, water droplets (condensation) may form inside the machine. This may result in a noticeable degradation in the quality of the copied image, the inability to properly scan an original, or the copies having no printed image at all.

■ Avoid locations where a considerable amount of dust accumulates.

SW14-0 Transfer bias pressure reduction mode /On, Off
SW14-1 Developing assembly idling mode /On, Off
SW14-2 Black belt addition mode /On, Off
SW14-3 Post-rotation reduction mode /On, Off
SW14-4 Flicker reduction mode /On, Off
SW14-5 Silent mode /On, Off
SW14-6 Terminal temperature rise noise reduction mode /On, Off

Select whether to enable or disable transfer bias pressure reduction mode.
Select "On" to avoid image defects (black spots) produced by transfer bias leaks occurring in a low-pressure region, such as one at a high altitude. This setting regulates the transfer bias to keep it from exceeding a predetermined level during printing.

[Detailed Discussions of BitSW14-1]
Select whether to enable or disable developing assembly idling mode. Select "On" to drive the main motor for a specified period of time to apply idling and developing bias (AC + DC) to prevent the thinning of the image density when the unit is installed or the developing unit is replaced in a low-temperature, low-humidity region. This mode works only on a new developing assembly and before a toner cartridge is loaded.

[Detailed Discussions of BitSW14-2]
Select whether to enable or disable black belt addition mode. If the user uses paper that causes fixed toner on paper to be fused and adhered to drum, selecting "On" will clean the drum by forming a black band on the drum surface during the reverse rotation which is performed after printing on 50 sheets.
