Send to kindle flaws or restrictions?

[solitarywolf]

I have sent several documents using the send to kindle feature.

I generally send EPUB files most of them work, but occasionally a few don’t. They are within the size limit of AMAZON’s restriction of 200 MB. Anyone know why I cannot send these other files I get a fail to send. All the time.

Are they not allowing certain books to be transferred?

For the most part, the only epubs I've seen rejected have errors in them. You can use epubcheck (standalone if you are familiar with running Java .jar files or from Sigil or calibre's ebook editor where epubcheck is an optional plugin).

Azw3 via USB works better. Or epub2 to Amazon's KDP.
They are fussier about the epubs than elsewhere, they should have working TOC UTF8 and pass both Checkbook (ladybug) and EpubCheck (tick) in Calibre Editor. It can also verify all TOC have destinations.

Also elephant in the room is security & privacy. No business should use it. What does Amazon do with the stuff? What security? It's a great temptation to scan the docs and profile users.

I wondered about that. Are they looking at what I’m uploading and denying certain titles? I guess only Amazon can tell me that. I have several epubs that I purchased from Sony years (over a decade) ago when I was using their PRS-505 series.

they may look in terms of advertising more than anything. to make a buck. thats not based on experience. only reason i use it. as usb ports only last so long before they stop working. some of mine on my laptop have stopped. dont want them all to stop

Very very doubtful
Much more likely is that there is some flaw in the epub that causes Amazon's conversion to fail. You could do all the epub check things with calibre tools,

Could converting to a different format then back to epub cure the faults?

Early on, when a lot of my epubs were being rejected, I found that converting to docx and then sending the docx worked reliably--I got no rejections.

I haven't had much trouble wiht epubs recently so I no longer automatically convert to docx and send the docx.

yes

and does not have to be to something different, even:

convert epub to epub in calibre is my go to fix for headscratching glitches.
it seems to fix all sorts of coding and structure issues

others say that is overkill but works for me,

alternatively you can use the modify epub plug in or the polish feature in calibre. that also does a great job e.g. it puts a well formatted cover where kobo expects to find it, repairs a TOC [ my fav feature]....

id do a cross format convert only if truly desparate, and use a downgrade to somthing simpler - like epub to mobi then back again

Send to Kindle web is failing on a large-ish (60 MB) ePub (Complete Works of H. G. Wells from DelphiClassics). It passes epubcheck, opens without issue with Apple Books, and imports successfully to Kindle Previewer 3. Too large for email or the Send To Kindle app.

I looked at the source, it looks pretty clean to me. Edit Book check complains about using named entities and CYMK color space. But these are not going to trip up S2K service. I had it remove unused CSS rules and fix a spine issue; trying to send again.

[update: Nope, failed again. Took about 50 minutes to fail, maybe it's just timing out.]

KP3 took awhile to 'index' (about 3 minutes), whatever that does. Obviously it has a very large TOC.

What is 'polish feature in calibre'? I see a plugin for it, but how to apply it?

Hi:

I am getting ready for when my trusty Kindle dies and I need to read ebooks on an iPad. I have been trying mightily to send the books from Calibre by email using the Kindle special email address. Nothing works and I have set up email with port number and other needed settings in Amazon etc. Always my email is rejected, the latest being that Kindle seems to blacklist any IPs my email server is using. I have not tried "GMX" yet.

Is a correct step by step set of instructions to do this available? Especially the ebook email settings in Calibre before trying.

Thanks

ps This is only my second posting in this forum as I have been using Calibre for a long time with excellent results.

So you are sending books from Calibre to the Kindle app on your iPad. If I understand correctly, those e-mails are being rejected. My recollection is that when you use that approach, you receive an e-mail from Amazon asking that you confirm that you want the e-book transferred to your device, and you must respond by clicking an active link in the e-mail. Are you seeing those confirmation e-mails?

Another concern: what is the format of the material you are trying to transfer? Amazon recently stopped transferring mobi files.

There are some alternative things you can try.

First, are you able to receive e-mails from other sources on the iPad? If not, you need to resolve that matter first. As to the Amazon setup - I don't think you need to do anything there. Amazon assigns the e-mail address for each Kindle device and app, and you don't need to change it. And trying to change it may introduce problems.

Second, it's helpful to identify where the Calibre library is stored on your computer. Once you know that, you have access to the e-book files and can transfer them using one of the other 'send to Kindle' options. They include:

• Generating a traditional e-mail (from whatever e-mail client you normally use), and attaching the e-book file.
• Downloading and installing Amazon's 'send to Kindle' app on your computer. You can then 'drag and drop' the e-book file into the app for transfer to your iPad Kindle app.
• There is also an Amazon 'send to kindle' drag and drop web site that you can access with a browser.

Of the methods listed above I think the send to kindle web page is the best and easiest to use. It supports books of up to 200MB (email is limited to 50MB) and has a progress indicator that shows the processing of you book by Amazon’s servers.

One downside of using the iOS app for personal documents is that it does not support KF8 (azw3) format so books will be delivered by Amazon in the less capable MOBI format.

Well, thank you. That worked!

But .......................

All the apostrophes and quote marks are trashed in the Kindle Read App. I recall this happened before when the email directly out of Calibre worked.

This is a font encode issue. Can you tell me what to change and where to restore the apostrophe and quotes.

Another thank you .......................

The simplest way is to install the "Modify ePub" plug in, then apply it with the "Encode HTML in UTF-8" item checked.

This will stay checked, so you can select a book, invoke the plugin and hit return after the first time.
