Settings

The six sections under Home → Settings, and the reader menu you open while reading, screen by screen.

Firmware 2.0.0-ko.1 · screens from the X3 (Korean UI)

Using the settings screen

Home → Settings lists six sections: System / Display / Reader / Controls / Library / Connectivity. Pick one with up/down and press Confirm.
Inside a section, move with up/down and press Confirm to change a value. Two-value settings flip on each press; settings with three or more values open a picker. Numbers step up one notch at a time and wrap from the maximum back to the minimum.
Back returns to the section list; Back again goes Home. Your changes are saved.

Moved since 1.6.5: Time to Sleep is under Display, Clear Reading Cache under Reader, Wi-Fi, Bluetooth, sync, and OPDS under Connectivity, and Use Book Metadata plus the two read-book options under Library.

Settings are saved to /.crosspoint/settings.json on the SD card. You can also edit them on the web server's settings page (Web server).

Rows marked for specific devices are hidden on devices without that hardware. Screens shown are from an X3.

About is always in English. Include the Device and Firmware lines when asking for help.

Line Spacing now has seven steps. A 1.6.5 value moves over when you update: Tight → 0%, Normal → +20%, Wide → +45%, Extra Wide → +60%.

Images = Black & White replaces 1.6.5's Image Grayscale toggle. Images are drawn as dots without gray levels, so pages with images turn like text pages.

Reader Font Family lists the fonts on your SD card. The default is the built-in Pretendard 10pt; for 14pt get Pretendard-14.epdfont, and for KoPub Batang KoPubBatang-14.epdfont. How to add fonts is in Customize → Fonts.

Customise Status Bar has a live preview. Toggle chapter page count, book progress %, the progress bar (book/chapter/hidden) and its thickness, the title (book/chapter/hidden), battery, the XTC status bar, and the clock (devices with a clock).

Dictionary: put StarDict files (.ifo, .idx, .dict or .dict.dz, synonyms .syn) in /dictionaries/your-dictionary/ on the SD card. While reading, use reader menu → Look Up to pick a word and see its definition. For the Korean dictionary and how Korean lookup works, see the dictionary guide.

Clear Reading Cache erases every book's index and your reading positions and reading time. If only one book misbehaves, use that book's reader menu → Delete Book Cache instead.

Bluetooth page turner

A Bluetooth remote (page turner) can turn pages. Turn Bluetooth on in the top row and connect with Scan for Remotes. Connected remotes stay under Paired Remotes. Map Buttons assigns page and chapter turns, Confirm, Back, or the reader menu to each remote button: pick an action and press the button within 15 seconds; holding it for 0.7 seconds or longer maps separately from a tap. Without mappings, the remote's default buttons still turn pages. While reading, reader menu → Bluetooth Page Turner turns it on and off.

Sync and OPDS

CrossPoint (KOReader) syncSettings → Connectivity → CrossPoint Sync

CrossPoint Sync (KOReader Sync in the Korean menu): enter a username, password, and sync server URL, then authenticate. No account yet? Sign up from the device. Set Server Type (CrossPoint / KoSync / Other) to match the server, and turn on Sync Clippings only with a CrossPoint sync server. Steps are in KOReader sync.

OPDS Servers: Add Server takes a name, URL, username, and password. The download folder (default: SD root) and file name format (Author - Title / Title - Author / Title) are set here too. Usage is under OPDS.

Plugins

From 2.0.0 the device can run plugins from the SD card. They start disabled on a fresh install; selecting Plugins opens Enable / Disable / Cancel. Once enabled, Plugins appears on Home, where you open an installed plugin or hold Confirm for a second to remove it. Plugins live in /.crosspoint/plugins/, /plugins/, or /.plugins/ on the SD card. Plugin Hub, which downloads plugins over Wi-Fi, is optional. Disabling plugins leaves their files in place.

Clippings are stored in /.crosspoint/clippings on the SD card and also appended to My Clippings.txt at the root in Kindle format. Each book holds up to 256 clippings on the X3/X4 and 1,024 on S3 devices.

Reader menu: toolbarSettings → Reader → Reader Menu Style = Toolbar

With Settings → Reader → Reader Menu Style set to Toolbar, the same functions sit in a bar at the bottom of the page: a slider on top to move through the book, and below it Contents, Text (font and spacing), and More (the rest of the menu).
