-When using your IoT Box, a common issue you might encounter is that your

-steps you can follow to find your IoT box.
-
-HTTPS Issues
-============
-
-Your IoT Box is not found? You probably have https issues!

-To check it, go to your database and verify if your database address
-starts with an https (like https://www.odoo.com). If this is the case,
-then you may have problems with your IoT Box image. It should be version
-18.12 or later.
-
-If your IoT Box image is from an earlier version, then you will have to

-Troubleshoot
-~~~~~~~~~~~~
-
-The PoS cannot connect to the IoT Box
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
--  The easiest way to make sure the IoT Box is properly set-up is to
-   turn it on with the printer plugged in as it will print a receipt
-   indicating any error if encountered or the IoT Box's IP address
-   in case of success. If no receipt is printed, check the following
-   steps:
-
--  Make sure the IoT Box is powered on, indicated by a brightly lit red
-   status LED.
-
--  Make sure the IoT Box is ready, this is indicated by a brightly lit
-   green status LED just next to the red power status LED. The IoT
-   Box should be ready ~2 minutes after it is started.
-
--  Make sure the IoT Box is connected to the same network as your POS
-   device. Both the device and the IoT Box should be visible in the
-   list of connected devices on your network router.
-
--  If you specified the IoT Box's IP address in the configuration, make
-   sure it corresponds to the ip address printed on the IoT Box's
-   status receipt.
-
--  Make sure that the POS is not loaded over HTTPS.
-
--  A bug in Firefox's HTTP implementation might prevent the
-   autodiscovery from working reliably. You could also manually set
-   up the IoT Box's IP address in the POS configuration.
-
-The Barcode Scanner is not working
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
--  The barcode scanner must be configured in US QWERTY and emit an Enter
-   after each barcode. This is the default configuration of most
-   barcode readers. Refer to the barcode reader documentation for
-   more information.
-
--  The IoT Box needs a 2A power supply to work with some barcode
-   scanners. If you are not using the provided power supply, make
-   sure the one you use has enough power.
-
--  Some barcode scanners will need more than 2A and will not work, or
-   will work unreliably, even with the provided power supply. In
-   those case you can plug the barcode scanner in a self-powered USB
-   hub.
-
--  Some poorly built barcode scanners do not advertise themselves as
-   barcode scanners but as a usb keyboard instead, and will not be
-   recognized by the IoT Box.
-
-The Barcode Scanner is not working reliably
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
--  Make sure that no more than one device with 'Scan via Proxy'/'Barcode
-   Scanner' enabled are connected to the IoT Box at the same time.
-
-Printing the receipt takes too much time
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
--  A small delay before the first print is expected, as the IoT Box will
-   do some preprocessing to speed up the next printings. If you
-   suffer delays afterwards it is most likely due to poor network
-   connection between the POS and the IoT Box.
-
-Some characters are not correctly printed on the receipt
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
--  The IoT Box does not support all languages and characters. It
-   currently supports Latin and Cyrillic based scripts, with basic
-   Japanese support.
-
-The printer is offline
-^^^^^^^^^^^^^^^^^^^^^^
-
--  Make sure the printer is connected, powered, has enough paper and has
-   its lid closed, and is not reporting an error. If the error
-   persists, please contact support.
-
-The cashdrawer does not open
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
--  The cashdrawer should be connected to the printer and should be
-   activated in the POS configuration.

+===============
+Troubleshooting
+===============
+
+IoT Box Connection
+==================
+
+I can't find the pairing code to connect my IoT Box
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The pairing code should be printed on receipt printers connected to the
+IoT Box and should also be displayed on connected monitors.
+
+The pairing code doesn't show under the following circumstances:
+
+-  The IoT Box is already connected to an Odoo database;
+
+-  The IoT Box is not connected to the Internet;
+
+-  The code is only valid for 5 minutes after the IoT Box has started. It's
+   automatically removed from connected displays when this delay has expired;
+
+-  The version of the IoT Box image is too old. It should use version 20.06
+   or more recent. If your IoT Box image is from an earlier version, then
+   you will have to reflash the SD card of your IoT Box to update the image
+   (see :doc:`Flashing your SD Card <flash_sdcard>`)
+
+If you are not in any of the cases listed above, make sure that the IoT Box
+has correctly started, by checking that a fixed green LED is showing next to
+the micro-USB port.
+
+I've connected my IoT Box but it's not showing in my database
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+When you connect an IoT Box to a database, the IoT Box might restart, if
+that is the case, it might take up to one minute before appearing in your
+database. If after some time the IoT is still not showing, make sure that
+your database can be reached from the IoT Box and that your server doesn't
+use a multi-database environment.
+
+My IoT Box is connected to my database, but cannot be reached
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Make sure that the IoT Box and the device running the browser are located
+on the same network as the IoT Box cannot be reached from outside the local
+network.
+
+Printer
+=======
+
+My printer is not detected
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If one of your printers doesn't show up in your devices list, go to the
+IoT Box homepage and make sure that it is listed under *Printers*.
+
+.. image:: media/troubleshooting_printer_01.png
+   :align: center
+
+If your printer is not present on the IoT Box homepage, hit
+*Printers Server*, go to the *Administration* tab and click on
+*Add Printer*. If you can't find your printer in the list, it's probably
+not connected properly.
+
+My printer outputs random text
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+For most printers, the correct driver should be automatically detected
+and selected. However, in some cases, the automatic detection mechanism
+might not be enough, and if no driver is found the printer might print
+random characters.
+
+The solution is to manually select the corresponding driver. On the IoT
+Box homepage, click on *Printers Server*, go to the *Printers*
+tab and select the printer in the list. In the Administration dropdown,
+click on *Modify Printer*. Follow the steps and select the Make and Model
+corresponding to your printer.
+
+.. image:: media/troubleshooting_printer_02.png
+   :align: center
+
+.. note::
+   Epson and Star receipt printers and Zebra label printers do not
+   need a driver to work. Make sure that no driver is selected for those
+   printers.
+
+My Zebra Printer doesn't print anything
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Zebra printers are quite sensitive to the format of the ZPL code that is
+printed. If nothing comes out of the printer or blank labels are printed,
+try changing the format of the report that is sent to the printer by
+accessing :menuselection:`Settings ~~> Technical ~~> Views` in developer
+mode and look for the corresponding template.
+
+Barcode Scanner
+===============
+
+The characters read by the barcode scanner don't match the barcode
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+By default, we assume that your barcode scanner is configured in US
+QWERTY. This is the default configuration of most barcode readers.
+If your barcode scanner uses a different layout, please go to the
+form view of your device and select the correct one.
+
+Nothing happens when a barcode is scanned
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Make sure that the correct device is selected in your Point of Sale
+configuration and that your barcode is configured to send an ENTER
+character (keycode 28) at the end of every barcode.
+
+The barcode scanner is detected as a keyboard
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Some poorly built barcode scanners do not advertise themselves as
+barcode scanners but as a USB keyboard instead, and will not be
+recognized by the IoT Box.
+
+Cashdrawer
+==========
+
+The cashdrawer does not open
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The cashdrawer should be connected to the printer and the *Cashdrawer*
+checkbox should be ticked in the POS configuration.
