我的Canon400D拍出的照片出现了黑斑，确定99%是Sensor[CMOS]脏了。不敢自己动手，只能找最近的Canon服务中心。
与Canon服务中心联系好之后，驱车前往。这是Canon在新泽西的服务中心，离住地约80公里，大概开了一小时才到。
服务人员很热情，了解情况后，收下相机和镜头，打了两份接收文件。叫我等。
等了不到一小时，通知我取件。并给了我两份竣工文件。告诉我作了全面检查，清洗了Sensor，清洗了镜头，给固件升了级。全部免费！而且告诉我，就是过了保修期，这些项目也都是免费的。
这真是没想到，听摄友们说，国内只有北京，上海，广州三地有这项服务，而且每月只一天。还说，保修期内只免费清洗一次，过了保修期清洗一次￥150元。可这里是终生免费清洗，且随到随清。可见Canon在美国的服务真好！
-------------------------------------------------
Canon400D在美国叫Canon EOS DIGITAL REBEL XTi，与国内叫得都不一样。
有摄友说，Canon把一等品销往美国，二等品在日本国内卖，合格品卖中国。不知此话当真？
不管怎磨说，Canon还是躇老美的，怕给他惹官司。美国人的维权意识就是强。

下面附几分维修文件，大家看一看，就这磨一点事，人家多认真！

美国人在天堂里！我们何时才能享受这等待遇？

我的40D和朋友的400D都是MADE IN JAPAN

正解！

诶，我们国人，无言中......

LZ很幸运啊,我这里最近的服务机构是在LA.

我的机器是美国带回来的，也是made in Japan。

没办法啊，落后国家，什么都落别人后边。

美国也就两个服务中心。
佳能的dSLR都是日本造的，而Nikon的基本都是泰国造的。

不止两个吧，就我附近就两个，一个在纽约法拉盛，一个在新泽西。法拉盛那个虽近，但易堵车。
去不了不要紧，多数人都是把机器寄去。
按Canon的要求，要寄机器和镜头（不寄电池和CF卡），问题机器拍的照片（刻成盘），问题说明，包修单，购买收据，用户详细地址。寄出后，你就可以享受此帖开头所说的全部服务了。当然，回来的寄费得由用户负担了。

楼主的机器是在美国买的还是在中国买的呢？难道Canon还是全球联保？

我的机器在美国买的，Canon的机器好像没有全球联保，当然，在中国买的到美国去保修恐怕不成。我上面说的寄件，也是说在美国买的，寄给美国的维修中心。

我寄过一次，下面EMAIL 上说可以寄两个服务中心中任一个(NJ or CA)，在保修期回程邮费是佳能出的。 如果已经过了保修期，或着所出问题不在保修范围(摔，进水，进沙等等)，佳能会通知你并给个估计，你要是同意修，付了钱佳能才会给你修。

Dear NPHOTO user:

Thank you for contacting Canon product support. We value you as a
Canon
customer and appreciate the opportunity to assist you. I am sorry to
hear that your EF 17-40mm f/4L USM lens clicks at 20mm.

Unfortunately, your lens will need to be sent to a service center to be

examined.

For factory service, please forward your lens to one of the Factory
Service Centers shown below. When shipping your lens, you are not
required to send any accessories (except lens caps). Be sure to
include
your name, street address (no P.O. boxes, please), telephone number,
and
a letter describing the issue with the product. If it has been less
than one year since the lens was purchased, we ask that you also
include
proof of warranty in the form of a copy of your sales receipt.

As we do not provide RMA numbers for service, we suggest using a
trackable and insurable service (i.e. UPS, Federal Express, Priority
Mail) to ship your lens. Please package the lens very securely in a
sturdy shipping box to prevent damage during shipment.

Please send your lens to one of the following Factory Service Centers:

Canon Factory Service
100 Jamesburg Road
Jamesburg, NJ 08831

OR

Canon Factory Service
15955 Alton Parkway
Irvine, CA 92618

The telephone number and hours are the same for both facilities:

Telephone: (800) 828-4040
Business Hours: Monday - Friday 8:00 a.m. - 12:00 midnight ET, and
Saturday 10:00 a.m. - 8:00 p.m. ET (excluding holidays)

Upon arrival at the Factory Service Center, your lens will be logged in

to our repair database and assigned a repair number. Next, the lens
will be examined and you will be advised of the findings. If the
required repairs are covered by the warranty, the repairs will begin
immediately. When the repairs are complete, the lens will be shipped
back to you via Federal Express or UPS.

The length of time for the repair will be dependent upon the nature of
the repair and availability of parts, if needed. Usually, warranted
repairs are completed within approximately ten to fourteen business
days
of the lens's arrival at the Factory Service Center. Please be assured

that your lens will be returned as soon as possible. We appreciate
your
patience and understanding in this matter.

All decisions regarding warranty coverage are made by the Factory
Service Center at the time of repair. If the repair entails something
that is not covered in warranty, or if the lens is out of warranty, a
written estimate will be sent to you at the address that you have
provided. The repairs to your lens will not begin until you approve
this estimate and make payment arrangements. If, after receiving the
estimate, you do not wish to have the lens repaired, please inform the
Factory Service Center of your decision as soon as possible. If you
decline the estimate, the lens will be shipped back to you unrepaired.

Once you have confirmed with your shipper that the lens has been
delivered, you are more than welcome to contact us for repair updates.

Please include your name, address, and telephone number, as well as the

serial number of the lens, in all repair status inquiries.

Please note that our U.S. Factory Service Centers are unable to accept
packages from or return equipment to addresses outside the United
States.

We hope this information is helpful to you. Please let us know if we
can be of any further assistance with your EF 17-40mm f/4L USM lens.

Thank you for choosing Canon.

Sincerely,

Erik
Technical Support Representative
