FACTORS LIMITING PRINTING SPEED
 Image Quality Adjustment
Note *1: Condition to print 50 copies (pages) continuously:
The average of the print ratio should be 35% or less for each color.
*2: ADC = Automatic Density Control: A control to ensure stable print density
*3: The printer sometimes perform the ADC control more than once. In such case, the time required can be obtained by multiplying "Time for once ADC" by "Number of executions".
*4: A/C = Area coverage:
Print ratio of each color
*5: 3 seconds x 4 colors
 Cooling down
This is performed to prevent the edges of the heat roll from rising in temperature when small-sized paper is used. If the temperature difference between the edges and the center
of the heat roll reach a certain level, the printer stops the current job to perform the cooling down operation. Time required may vary according to paper size, number of printed
pages, etc..

(Toner Cartridge → Developer)
• To prevent making a density difference between input
data and output image.
• To prevent toner from being stirred unequally.
• To supply toner when printing an image with high print
ratio.
When the printer comes into the following conditions, it stops the job temporarily
at the timing given for each condition to perform the ADC control.

To prevent excessive amount of toner in the black developer
when printing in black and white continuously.
After printing in black and white continuously, the printer rotates the rotary if it
detects that the toner dispense time during the job is equivalent to 30 pages.
