HP deskjet 3820 喷墨打印机修好了

坏调的齿轮用万能胶粘后发现不行,该用电烙铁热粘,呵呵,这样就粘牢了,打印机又可以工作了。grin

HP 3820 喷墨打印机在电源打开的情况下,按住电源按钮不放松,按出纸按钮4次后都松开,打印机打印自测页,可以看到总共打印了多少页和序列号,软件版本等信息,我的是820页。

HP Deskjet 3820

I found  fixyourownprinter.com have this topic : HP Deskjet 3820
These people have  the same problem like me

The cartridge cradle of my 3820 is jammed…will not move from home position on the right. Any fixes?
It is indeed a shame but there is nothing you can do. If it's out of warranty HP will not offer you any solution other than selling you a new printer. Consider the whole episode a learning experience. See my last post in this thread. If you get a DJ 6122 the cartridges will not be a loss.

I once got blamed for a DJ 3820 konking out because I had recently worked on the system that used it.

I repair printers for a living so casually putting them in the trash it not what I抦 all about. I encourage people to have their 'old' printers repaired because I genuinely believe it is a better value than buying a new printer, unless they need different capabilities. Why do you think I spend so much time on this forum? My only compensation is the satisfaction of saving repairable equipment from the landfill.

All DJ printers will eventually need service. I regularly repair models that are approaching 10 years old. All they generally need is a mechanical 'tune-up', but if the electronics has failed, fairly rare, they are instant parts machines. People will not spend $150-$200 to repair a typical inkjet printer.

The DJ 3820 was made for a price driven market, i.e. the customer wants a 'deal' and the seller 'throws in' a cheap printer with the computer. All HP and others are doing is filling the demand and making a profit by selling short-filled cartridges. If you have an argument with the repairability and reliability, take it up with HP. All I know is that you can't repair them without parts and/or documentation. Check for yourself.

HP Pavilion 畅游人的9合一读卡器竟然是USB 1.1的

以前我用的存储卡都小,每次写入和拷出时等的时间短,也没注意HP Pavilion 畅游人的9合一读卡器是 USB 1.1 的还是USB 2.0 的,最近新购入了1G和2G的SD卡,发现读取速度就在个8、9百K/S 的速度,感觉是不是买到假SD卡了,就把我以前的存储卡,XD,MS,MMC等都拿出来试,都是这个速度。看来是9合一读卡器的问题,今天打HP 800电话问了,得到明确答复所有 HP 的9合一读卡器都是USB 1.1 接口的!

HP Pavilion 畅游人w5060cl (HP Entertainment PC) 提供给用户的竟然是廉价的USB 1.1 9合一读卡器,>1G的存储卡越来越普遍,用USB 1.1 9合一读卡器读取文件要浪费多少时间啊。
我做了个测试:
700MB的文件写入 需要16分钟(900K/S)
那么2G卡上的文件全部读出要37分钟  -_-….zzzZZZ

HP的喷墨打印机罢工了

hp deskjet 3820 打印机开机就要进纸,只是空转,打印模块也不出来,关机也是如此。
自己检查后发现是黑墨盒漏墨,在盒子底部形成一个小包,卡住打印模块进出。
把小包撬掉,还是不工作,问了hp维修的,是服务站时序错误,修理要7、8十左右。
HP 维修是比较贵,象这个问题,应该只是机械部分的,估计是齿轮的状态不对。

等周六拿去修。cry
