Win7系统安装联想LJ2500方法
1.连接电脑与打印机，接通打印机电源，系统自动检测安装驱动后，在“设备和打印机”窗口中出现“USB打印支持”项。

2.右击，在快捷窗口中选择“属性”，点击。

3.在弹出窗口中，选择“硬件”栏中设备“LEGENDLJ2500”。

4．点击“属性”
5.在弹出窗口中点击“常规”栏目下的“改变设置”：
6.在弹出的窗口中选择“更新驱动程序”，点击：
7.出现下面窗口，选择“浏览计算机以查找驱动程序软件”，点击：
8.出现下界面，选择“从计算机的设备驱动程序列表中选择”项：
9.在弹出的窗口中选择“打印机”，然后点击“下一步”：
10.在驱动程序列表中选择“BROTHER HL-2140(或2150N)”,然后点击“下一步”：
11.系统会弹出更新驱动程序警告，选择其中的“是”：
12.屏幕出现如下界面：
13.点击“关闭”。

在“设备和打印机窗口”中就会出现BROTHER HL-2140(或BROTHER HL-2150N)打印机图标。

14.BROTHER HL-2140(或2150N)打印机驱动程序能基本兼容联想LJ2500打印机。

打印测试一切正常，唯一不足的是在首张打印页面的左上角有几个小黑点（不留意看不出来……）。

灯检测模式功能Drum 简单测试页打印机打印简单测试页，打印完毕后回复ready 状态。

Ready打印配置&打印字体测试页打印机打印当前配置和内部字体表，打印完毕后回复ready 状态。

Alarm复位打印机恢复出厂设置，打印完毕后回复ready 状态。

Data十六进制数据打印打印机将数据打印成十六进制数据，检查数据错误或问题。

要退出此模式必须关闭打印机。

2（二）、LJ880/LJ1600 按住演示按钮2 秒，直到控制面板所以指示灯慢速闪烁，打印机打印出一页演示页，打印机必须处于就绪模式。

3（三）、LJ2110/LJ2210/LJ6P/LJ6P+/LJ6010 按住面板按钮打开打印机电源开关。

面板上四个灯亮后，第一个灯再亮时松开面板按钮。

按住面板按钮：一秒钟之内松开面板按钮为打印普通自检样张。

按住直到第二个灯亮再松开面板按钮，为打印硒鼓寿命样张。

按住直到第三个灯亮再松开面板按钮。

为打印机复位（初始化）。

4 （四）、LJ3010A/LJ3116/LJ3220A/LJ6C/LJ6C+ 在就绪模式下按一下联机，使打印机处于脱机状态，按一下执行键，打印出一页测试页。

在就绪模式下按一下联机，使打印机处于脱机状态，同时按住CANCEL 和ALT ，待蜂鸣器响一声，打印机会重启动，即恢复出厂状态。

5 、LJ2800 关闭打印机开关，关闭前盖。

按住取消键，开机，至墨粉灯亮。

然后按一下启动按钮，可打印测试页。

关闭打印机开关，关闭前盖。

按住取消键，开机，至纸张灯亮，即恢复出厂状态。

联想lj2500拆机教程1、拆下小面板即可看见硬盘，注意把卸下的螺丝分类放好，依次拿出光驱和无线网卡。

2、使用一字螺丝刀或撬棒撬起键盘，撬开时注意力度。

3、撬起键盘后，可见主板，内存条和散热器，可分别拆下。

底盖拆卸以及散热器清理：lj2500的底部散热器那里底盖的螺丝三颗、硬盘底盖螺丝两颗、无线模块底盖两颗、光驱固定螺丝一颗（暂时看不到光驱固定螺丝）。

散热器底盖拆开看到左下侧的内存、散热铜管末端是处理器、中端是北桥、末端是GPU芯片。

底盖的三颗螺丝中，有两颗是用卡簧固定在底盖，这样的设计可以免去了我们如何存放螺丝的烦恼哦！第三颗螺丝是沉头的有特别的作用。

散热铜管是弯曲设计的，在GPU芯片那里的空间很有限，不能做一个特别大的散热片或者外加弹性压片，而沉头螺丝的作用就是把图中的弹性压片压下。

（主要是因为空间限制才这样设计的。

）弹性压片的作用是让散热片与GPU表面更好接触，好处是不会压坏芯片，不过因为压片是单边的，所以可能存在受力不均问题哦！处理器那里的压片是四边的，所以受压均匀。

今天拆机重点是清尘，散热风扇由三颗螺丝固定，只要拧开三颗螺丝就能取下散热风扇，这里需要注意别样散热器撞倒主板上哦，因为主板上的电子原件密集，碰撞容易造成损坏。

PS：这里需要注意一点-拆机前一定要把电池卸下，这个是为了避免在拆机过程中造成主板短路，要好好记住哦！散热风扇已经被拆卸下来了，散热风扇给我的感觉是比较薄，其次散热风扇底座竟然是塑料材质。

薄说明散热风扇的功率有限，塑料材质的风扇座导热性不如金属。

散热风扇面盖有四个螺丝固定，拧开后可以拆除风扇，不过我没有拆开。

原因有两：1、我没有这么小的螺丝刀；2、我先用刷子清扫了一下里面的尘埃，然后用气枪吹干净。

当然仅仅用刷子不能清理到风叶的缝隙，我们可以使用棉签一片片清理。
