PRS-900 Pdf file experience

I was trying to read a 12.1 MB pdf file (downloaded from OReilly). This book has quite a few images. Although I did not have problems viewing the images on the reader, the reader froze when I was trying to go to the next page at the end of the table of contents, and a couple of chapters.

I could get around this by going to the next page number (by GoTo function)

I am wondering if epub format is more suitable for this reader? or anybody has seen a problem like this?

Just tested by downloading the same book in the epub format, it works fine on the epub format and the tables are also showing up correctly.

So it looks like it may be better to convert the pdf to epub before viewing on the reader. Comments?

I read a lot of PDFs (I am a PhD student) and some of those larger than the 12 MBs you mentioned. The largest one I have is 28 MBs, and I don't really notice any slowdowns - but it isn't heavy on graphics, just A LOT of pages. I haven't had the device for long, but I have more than 300 PDFs archived with annotations taken on the PRS, many larger than 10 MBs.

Slowdowns are common - especially if:

1) The current or following page has some heavy images;

2) I take handwritten notes and leave the note tool open when switching page;

3) Use Zoom or Resized Text.

4) The 3G connection is on and the Reader is checking for new deliveries/downloading new deliveries in the background (this seems to be a problem if you have many subscriptions active, otherwise it's too infrequent to notice).

Now, combinations of the above have occasionally (rarely, I should say) led to VERY LONG loading times. With "very long" I mean - up to a minute or so. Which feels like forever, if you are trying to turn a page. But, this has happened rarely and it has never completely frozen my device.

I had one freeze that forces a hard reboot (using the reset at the bottom of the device). It happened once when opening the dictionary - go figure...
Never had the device freeze otherwise.

Question Random blank pages in pdf

Hello vxf,

Interesting that you use the PRS 900 with your study (I am currently applying for a PhD myself and am planning to use the PRS 900 for the same reason). I am curious on your developed method: how do you produce your PDF's or do you ever have to clean up your PDF's to make them display better? I.e. I have had a couple of PDF's suddenly appear with a blank page in the reader or in the PC reader while it still displays perfectly in Adobe reader.

Thank you in advance.

When I make my own files, say from a word document, the only thing I make sure of is not to use Times New Roman. At times, it creates display problems in PDFs.

Aside from that, I use BRISS to crop margins and, occasionally, to reorganize text (for example, if it is in multiple columns).

I have not had the 'blank page' problem myself.

If you are making your own documents, I suggest converting them to ePubs. PDFs are big and slow and the text doesn't reflow properly. Using ePubs gives you a lot more functionlity and reflowable text. There are several good, free programs to convert Word DOC and RTF to ePub.

If you do create PDFs for a PRS-900, I suggest that you make the document size appx. 3.5 x 6 inches and use small margins all around. I would keep the margins to about 0.25 inch or less. This size of PDF should look good on your 900 as it is the size of it's screen (excluding the information bar at the bottom of the screen). As mentioned above, avoid the Times New Roman font. A lot of people actually prefer a sans serif font on digital readers, but use whatever is easiest for your eyes to read.
