1.12.1 Factors Limiting Printing Speed

Fuser cool down control
When the temperature of the Fusing roller edge reaches 235 °C, printing operation
stops for about 40 seconds until the temperature falls to 225 °C. If the temperature of
the Fusing roller edge reaches 194 °C when printing on smaller width papers, printing
operation stops for about 55 seconds until the temperature falls down enough.
(Monochrome printing speed becomes slow.)
Toner supply operations within a cartridge during a continuous Monochrome
printing.
When performing monochrome printing continuously, the rotary starts rotating in
process of print job in order to supply toner. (The speed of simplex monochrome
printing turns down.)
1. When the number of continuously printed pages reaches 255 (counted with
Vsync), the print process is interrupted while the rotary rotates 360° (until the
Vsync counts another 1) to supply toner.
2. When the integrated value of the toner counter reaches a certain level, the
print process is interrupted while the rotary rotates 360° (until the Vsync
counts another 1) to supply toner.
When performing duplex printing, the printing speed does not turn down as the rotary
rotates while the duplex unit is re-feeding the paper.
Toner supply control
After 3 hours have passed since the power-on without any printing operations,
developer rollers are rotated to stir toner inside of them in order to prevent banding on
printout from occurring. (This may cause delay in printing.)
Product Description
Patch Control (AIDC)
Patch control is activated by the engine factors on occasions described below.
At power on
When the Photoconductor unit is replaced
When the Toner cartridge is replaced
When the target value is changed due to the lifetime of the toner cartridge. (It
may affect printing
Note *: Approximate frequency is as follows. (5 % duty or color printing with 5
% of each color, in case printing 5,000 pages continuously.)
