Firmware Update Kindle 5.19.2 software is available

I side-loaded an AZW3 comic (downloaded 'for transfer via USB' back in the day) and it works fine (except no cover thumbnail appears). Note this has ctype=EBOK.

KCC now I think uses ctype=PDOC but in past used ctype=EBOK.

I do not know if that matters, but it would be interesting to know if it does.

In any case AZW3 is easily inspected so some other difference in HTML/CSS might shed some light.

Based on your profile, you are using a Scribe? The problem was only reported on PW11/12 and Basic 11 so far. and yes your are correct about pdoc ebok, I'll ask around.

EDIT: a scribe 2022 user reported the problem just now

Have you tried loading any files generated by kcc? I made some sample files a while ago if you want to try loading a mobi.

I have Scribe 2022 and Scribe Colorsoft. I have seen the issue on the latter with a particular comic in my Amazon library (which downloaded AZW3 rather than KFX), but I cannot remember which one it was, so cannot reproduce. I don't use KCC.

But then I did try KCC, and while I'm not seeing extra whitespace, I'm seeing a lot of pages that do not render and remain blank.

AZW3 files that were downloaded from Amazon do not seem to work correctly either: I downloaded one to my Kindle Touch and side loaded it to Scribe. (This would identify as EBOK, not PDOC as with the KCC book). Some pages display a black square instead of rendering the page content.

KCC has orientation setting available, but not the AZW3 I moved over. But it's moot since neither works.

Maybe it 'should' work but do we really think this will ever be a priority for Amazon to fix?

Which is another reason I don't use KCC and use Kindle Create instead to get KFX for side loading, or if I want it in my Library, PDF & Send To Kindle (hey, you can draw on them! or colorize BW manga/comics on Scribe Colorsoft).

This is unfortunately an extremely common problem on 2025 Scribes: https://github.com/ciromattia/kcc/issues/1216

It also happens on 2022 Scribes with certain option choices like png/crop: https://github.com/ciromattia/kcc/issues/1224

KCC can output PDF and autosplit on 200 MB. And you can choose png option for writable PDF output via Send to Kindle, which will use 16 color lossless png instead of 256 color jpg that kindle create uses. Which means a much sharper image on a 16 color eink display at much smaller filesize since 16 colors fits in 4 bits (2^4=16) while 256 colors fits in 8 bits (2^8=256).

Also, Kindle Create often renders images at 1500x2250 last time I checked, which isn't quite the 1860x2480 of the Scribe 2022.
