翻译英文：我们传真无法传到你们那，请检查是否你们的传真机有故障

We are not able to fax through, please check if any problem with your fax machine.
或者按照你想表达的意思，同样可以说
We are not able to fax through, please check if your fax machine is working properly.

p.s.正确的表达方法当然很多，我在国外的时候和同事客户就这么讲的。楼上太搞笑了吧，跟外国人这么说话人家要笑翻过去啦~~

Our fax can not reach you, please check to see if there is a problem with your fax machine

Our fax is unable to pass to yours, please check whether your fax-machine is out of order.

Our facsimile is unable to pass to your that, please inspect whether your facsimile machine does have the breakdown .

专业级翻译，信不信由你...（偶们大学教授翻译的，o(∩_∩)o...哈哈...）
