14.3.1

2nd image transfer control

• To transfer the toner image formed on the transfer belt onto the paper, the 2nd image
transfer voltage supplied from the high voltage unit is applied to the 2nd image transfer
roller.
• Resistance of the 2nd image transfer roller changes with an environmental change, dura-
bility, and other factors. To maintain an optimum output voltage, fixed current is passed
through the 2nd image transfer roller and the voltage being outputted at that time is
detected. An appropriate 2nd image transfer voltage is determined based on the mea-
sured voltage and other information such as "type of paper used", "temperature and
humidity", "color mode or black mode", and "1-sided/2-sided".

A. Execution timing
• The 2nd image transfer control is executed when a print job is received under any of the
following conditions:
"Main power switch is turned ON"
"Sub power switch is turned ON"
"The machine exits the sleep mode"
"The threshold value of a change in machine interior temperature is exceeded."
