12-6. Toner Replenishing Control
• Replenishing of the supply of toner is determined based on the T/C ratio and B/W ratio.
• If T/C is 14 % or more, toner replenishing is not carried out regardless of the B/W value.
• If T/C is less than 14 %, toner replenishing is determined according to the B/W value.
• Toner is replenished until T/C becomes 14 %.
