FACTORS LIMITING PRINTING SPEED

Image Quality Adjustment

1 During printing To keep the image density at target level.
3
2 Admix* • To prevent making a density difference between input
→
(Toner Cartridge Developer)
• To prevent toner from being stirred unequally.
• To supply toner when printing an image with high print
→
3 Collection(Developer Toner To prevent excessive amount of toner in the black developer
Cartridge (collection space)) when printing in black and white continuously.
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..

ratio.
Condition and control
1. When printing more than 51 copies (pages) continuously
Every time the printer makes 50 copies (pages), it stops the job temporarily to
perform the ADC* 2 control.
2. If the printer detect a near-end of Toner Cartridge, it changes the timing of the
ADC control to every 25 copies (pages).
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.
1. A/C* 4 = 100% : 5 per page
2. 35% Average of A/C < 100% : Every 5 to 50 pages
3. Average of A/C < 35% : Every 50 copies (pages)
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.
