Troubleshooting - Frequently asked questions:

Q1. Why can I not preview my mobi book in the Kindle E-reader device mode?
A1. The Kindle E-reader device mode does not support preview of books in the older generation Mobi 7 format. We recommend converting your Mobi 7 book to EPUB so that you can preview your books using all the device modes and see if Enhanced Typesetting is supported for your book.

Q2. I see small boxes instead of the actual text in the table of contents while previewing an Indic language eBook on my Windows PC. What should I do?
A2. This can happen when your machine does not have the necessary fonts to display the text. You can resolve this by installing the corresponding language pack from Language Control Panel on your Windows PC. You might have to restart your machine for the installation to take effect on your computer.

Q3. I am unable to preview my eBook in Word format. What could be the reason?
A3. Some of the potential reasons could be: 
• The file is password protected. 
• The file name contains non-ASCII characters. 
• The eBook was created using an old version of Word (Example: Microsoft Word 97 or before). 
• The eBook is in a language other than English. 

Q4. Why do I not get an option to navigate by tables or lists for some books?
A4. The ‘Navigate by’ feature is only available for books that support Enhanced Typesetting. If your book supports Enhanced Typesetting, the ‘Enhanced Typesetting’ label is displayed under the ‘Device’ menu in the Inspector window. Also, the options that you see under ‘Navigate by’ are populated depending on the content in your book. If there are no tables in your book, you will not see an option to navigate by tables.

Q5. For a specific location, why can I not see the same content on Kindle Previewer and on my Kindle device?
A5. In a reflowable book, the content adapts to different screen sizes and font sizes. For example, as you change the font size on a device, the text you see in a given page might flow in to the next page. For the same reason, there might be differences between the content you see in a given location on KPR and on devices of different sizes. For fixed-layout books, given there is no reflow, the content you see in a specific location will match across devices of different sizes and on Kindle Previewer.

Q6. When I open my book on Kindle Previewer, some part of the content goes beyond the margins and is not visible.
A6. This could happen if you are using negative margins in your content. If that is the case, although the content is not visible on Kindle Previewer, when the book is rendered on a Kindle app or Kindle device, it will be displayed properly.

Q7. The zoom option on the Inspector window is not enabled for my book.
A7. The zoom functionality is used specifically for print replica books and will be disabled for other types of books. For books in other formats, if you wish to zoom into an image, you can double click on an image to open the image viewer and then double-click again to zoom-in.

Q8. Why can I not see thumbnails for my book when I open it in Kindle Previewer? 
A8. Thumbnail previews are currently available only for reflowable books that are enabled for Enhanced Typesetting. If your book is a fixed-layout book or is not supported for Enhanced Typesetting, you will see the previewer pane without thumbnails.

Q9. I get a warning with the message "App is not optimized for your Mac" when I launch Kindle Previewer 3 on my Apple computer. Is this a problem? 
A9. No. This is due to an update to Mac OS X, to warn users when they run a 32-bit application. Please download the latest 64-bit version of Kindle Previewer for Mac OS X from the ‘Downloads’ section on this page to avoid these warnings.
