为什么出这个错误？换了什么部件没有？说明一下前因后果。

关机，稍凉。
1)拉出转印处理单元，手工转动转印带，确定转印带部分没有卡住(比如废粉收集单元)

2)开机进入47模式，输出， 41-12，看看马达是否转动
3)47模式，输出，49-00，看看有没有出错(这个是检查光码盘的)

电机陡然出故障可能性不大，很可能是光码盘碳粉累计脏了，

F23-09 indicated with lines on copies.
Solution
CAUSE: Toner is backing up or solidifying in the cleaning unit box for the transfer belt causing the transfer belt drive motor (M18) to bind.There is insufficient airflow during idle which causes the internal machine temperature to rise.

马达烧了不正常，治标不治本。废粉部分要检查一遍，确保马达安全。
