imageRUNNER C1022 / imageRUNNER C1022i / Color imageRUNNER C1030 / Color imageRUNNER C1030iF
This control corrects values of primary charging biases and developing biases to obtain an optimum image under the detected environmental condition.
Explanation of operation
The environment sensor sends detected temperature and humidity to the DC controller as a temperature signal and a humidity signal.
The DC controller detects the printer's installation environment based on these two signals.
The DC controller requests the main controller to send a command to execute environment related corrective control at the following timing.
- After power-on
- When the front cover is closed after the replacement of the toner cartridge
- When a specified period of time elapses after the execution of this control
- When a specified number of prints are completed after the execution of the previous job or after the replacement of the toner cartridge
- When a specified level of environmental change (temperature/humidity) has been made after the execution of this control
- When the DC controller received the execution command from the main controller
The DC controller executes the following measures to prevent an image failure after the execution of this control.
- Change the primary charging bias value.
- Change the developing bias.
- Request the main controller to execute image gradation collective control.
