1.11 Measurement of Transfer Guide Bias

The transfer charger bias is applied to the pinch roller and the paper guide plate to prevent the transfer charger charge from escaping through the recording paper during transfer. To analyze the cause of a transfer failure which has occurred, you can output the transfer guide bias in the output test at any time and then measure the voltage.

Important:

Measure the transfer guide bias with the toner cartridge and the process unit taken out from the copier and the front cover open. Also, keep the front cover switch and interlock switch (front cover) ON by using the switch jigs (big/small).
