___you ____further problems with your printer,contact your dealer for advice.should had ,
为什么不能用 in case ,that

你的答案是错的.应该是should -- - have.（should +动词原形）
in case (== if) +句子：如果,万一- - - - .
Should you have further problems with your printer(条件状语从句部分),contact your dealer for advice（主句部分）
=== In case you should have further problems with your printer,contact your dealer for advice
再问： In case you should have further problems with your printer, contact your dealer for advice. 为什么要加should 呢？ in case you had further problems..... 这个可以吗？
再答：你好。in case you had further problems.....是错的。以下都是正确的：1 in case you have further problems (主将从现原则) 2 In case you should have further problems （should的使用在于说话人认为“假如”或者“万一”，因为在他看来have problems是有可能的）
再问： shoul 是万一， in case 在这里也是万一，会不会重复了呢？
再答：你好。这一点你就不必担心了。英语与汉语不一样，不是一个概念。在许多场合in case可以搭配should.你的句子就是一个例子。其实两个短语是通用的，可以相互转换，in case后面带的现在式、虚拟时态，都是表示“以防万一”的意思。 Take an umbrella in case it rains/ should rain. 未雨绸缪。快周末了，祝你周末愉快。
