Xiaomi’s compact photo printers have become a popular solution for instant prints directly from a smartphone. Xiaomi Mi Portable Photo Printer (often called the Mini) uses ZINK technology to capture images without ink cartridges. However, first exposure to the device often raises questions among users, especially regarding initial activation and pairing with a mobile device.
The adjustment process takes a little bit of time, but it requires a certain sequence of actions. It's critical to properly install the paper cartridge before power is turned on, because the calibration mechanism starts at that point, and if you skip this step, the printer will not be able to correctly recognize the type of paper and the number of sheets left.
In this guide, we'll take you through all the steps from unpacking to advanced color calibration, and you'll learn how to avoid common errors that lead to paper getting stuck or artifacts appearing in images. The first insertion of a ZINK cartridge should only be done when the printer is off, otherwise the sensors may not count the start sheet. Let's get into the process in detail.
Preparation of equipment and installation of the cartridge
Before you start any manipulation, make sure you have the printer, charging cable and, most importantly, a package of ZINK photo paper. Inside the box of paper, there is always a special blue calibration sheet (Blue Smart Sheet) that can not be thrown away or used for printing, as it contains information about the color settings for a particular batch of paper.
Insert the cartridge into the appropriate compartment on the back of the device. Make sure the color sticker on the cartridge matches the color marking inside the compartment. Once you install the cartridge, close the lid until you click the characteristic click. USB-cable.
Press the power button on the top of the button, and the indicator should light up in white, and then start flashing yellow, which signals the initialization and calibration process, while the mechanism stretches the start sheet and adjusts the thermal head.
- 📦 Make sure the cartridge is inserted to the point and snapped.
- 🔵 Find a blue calibration sheet in a pack of paper and don't throw it away.
- 🔋 Connect the printer to a network or a superbank with a current of at least 1.5A.
- ⚡ Wait for the cyclic noise of the mechanisms to complete before further action.
⚠️ Warning: Never open the back cover while the printer is running or the indicator is flashing.This can lead to paper getting stuck and damage to the thermal head.
☑️ Verification of press readiness
Installation of the application and pairing over Bluetooth
The official application is required to manage the Xiaomi Mini printer. Depending on the region and model, it can be Mijia (Mi Home) or a specialized application Xiaomi Print. For users from the CIS and Europe, Mijia is most often required, which is available on Google Play and the App Store.
After installing the app, sign up or log in to your Mi Account. Turn on Bluetooth and geolocation on your smartphone. In the app, click the device add button (“+”). The system will automatically start searching for nearby devices. When your printer image appears on the screen, click “Plug in”.
While pairing, the application may request a firmware update. It is strongly advised not to ignore this step, as new versions of the software often contain patches to work with new batches of ZINK paper. The update process takes several minutes, during which time the phone must be next to the printer.
If the automatic search didn't work, try resetting the printer's network settings, press the power button for 5-7 seconds until the indicator flashes orange, which will put the device in visibility mode.
What to do if the phone can’t see the printer?
Setup of printing parameters in the annex
The Mijia printer interface is minimal, but it hides important settings. Once you select a device from the My Home list or the devices section, you're taken to the main control menu, and you're shown the battery level and the number of sheets left.
Go to the device settings by tapping the three dots or gear in the corner of the screen, and you can change the printer name here, which is useful if you have multiple smart home devices, and you can also use calibration on this menu, which we'll talk about separately.
When choosing a photo to print, look for framing options.The app offers different aspect ratios, but for a 3x4-inch model, it's better to use automatic framing or a 3:4 format to minimize trimming of important details.
- 🖼️ Select a photo from the gallery or take a picture through the app's built-in camera.
- ✂️ Adjust the frame boundaries by dragging the image with your finger.
- 🎨 If you wish, apply filters or add stickers/text before printing.
- ⚙️ Check the number of copies in the settings before starting the process.

Use the “Passport Photo” feature in the app to automatically get the right sized shots for documents if your model supports this mode.
Color rendering calibration and maintenance
ZINK technology, which means that color is formed by temperature, and over time or when you change the batch of paper, the colors can float away, and to compensate for this, you use the same blue sheet that was included in the kit.
To start calibrating, insert the blue sheet into the printer as if you were going to print a normal photo. In the app, find Calibration or Color Customization. The printer will stretch the sheet, read the data from it, and return it, and then the color reproduction should become more accurate.
Regularly cleaning rollers will also prolong the life of the device.Rub visible parts of the mechanism with a soft dry cloth without pile.Do not use alcohol or aggressive chemicals, as they can damage the plastic elements and the heat head.
| Status of the indicator | Meaning | Action. |
|---|---|---|
| White (permanent) | Ready to work. | You can type. |
| Yellow (blinks) | Calibration/printing is in progress | Don't touch the device. |
| Orange (permanent) | Error/Low charge | Charging or checking paper |
| Orange (blinks) | Interconnection mode | Search in Bluetooth. |
⚠️ Warning: If the indicator is red or flashing orange quickly, check if the cartridge is inserted correctly.
💡
Calibration with a blue sheet is recommended for each replacement of the cartridge with a new pack for the best color quality.
Addressing common problems
One of the common problems is paper getting stuck, which can happen if the sheets are stuck to static or humidity, if the printer stops making sounds and the indicator lights up orange, gently open the back cover. Remove the crumpled sheet, pulling it in the exit direction, but without sharp jerks.
A pale print or lack of colors often indicates a battery is dead. It takes a lot of current to print one photo. If the charge is less than 30%, the printer can start printing, but stop mid-process. Always charge the device to 100% before an important photo shoot.
Bluetooth connectivity problems can be caused by smartphone operating system updates. If the app stops seeing the printer, remove the device from the Bluetooth list in your phone's settings and re-add it through the Mijia app.
- 📉 Pale Colors: Check the battery power and calibrate the printer with blue leaf.
- 📄 Paper clogging: remove the sheet, blow out the dust compartment, insert a new cartridge.
- 📱 Communication Error: Reboot Bluetooth on your phone and reconnect the device.
- 🔋 The printer is not turned on: replace the cable USB or a power supply to a more powerful.

Paper saving and care tips
ZINK photo paper is expensive, so it's important to minimize the amount of waste. Always preview your smartphone before you print it. Use framing to avoid printing unnecessary parts of the image that you'll have to cut.
Store the cartridges in a cool, dry place, away from direct sunlight. The packaging should be sealed because the paper is sensitive to moisture and light. The open pack is best used for 6 months for guaranteed quality.
Check the charging contacts regularly on the printer itself, which may accumulate oxidation or dust over time, leading to poor charge and, as a result, printing problems.
