You just ran an important document for printing, but instead of clear text you got sheets with blurred stripes, missing letters or vertical white lines? The problem of βstripedβ printing in Xiaomi printers is one of the most common, and it can occur in both budget MiJia Photo Printer and Mi Laser Printer laser models. In 80% of cases, the malfunction is fixed on its own without contacting the service center, but for this you need to accurately diagnose the source of the problem.
In this article, we will discuss all possible causes of the strips - from banal clogging of the print head to firmware failures, as well as give step-by-step repair instructions for each situation. 1S, Mi Portable Photo Printer and Mi Laser Printer 15000A, Because they have specific "weaknesses" in their design, and if your printer is warranty, there's a section at the end of this article on how to avoid losing free repairs when you're manipulating yourself.
1. Clogging of the print head: the most common cause of stripes
Xiaomi print strips are 60 percent contaminated with duzes in the print head, and this is true for inkjet models (MiJia Photo Printer, Mi Portable), where the ink dries out and forms a crust that blocks the normal flow of paint. Laser printers (Mi Laser) also suffer from clogs, but there the problem lies in the toner cartridge or the photo drum.
How do you know if it is the head that is to blame?
- π Vertical stripes β if they go parallel to the cartridge movement, it is a sign of clogged duzes.
- π¨ Missed colors β for example, the photo does not have a blue or red hue.
- π Blurred edges β text or graphs appear βsmearedβ horizontally.
For Xiaomi inkjet printers, there are two ways to clean:
- Software cleaning through the printer menu or Mi Home software (suitable for weak blockages).
- Manual washing using a special liquid (if the software method did not help).
β οΈ Warning: Never use alcohol or acetone to wash the head - they destroy rubber seals! Only specialized water-based solutions (for example, PrintHead Cleaning Solution).

If the Xiaomi MiJia printer has not been used for more than 2 weeks, start the Deep Clean feature in the device menu before printing.
2. Problems with cartridge or toner: when the stripes are the fault of consumables
If Xiaomiβs printer started stripping after replacing the cartridge or refueling, the problem is almost certainly with poor-quality consumables or improper installation, both inkjet (MiJia) and laser (Mi Laser) models.
| Type of printer | Signs of a problem | Probable cause | Decision |
|---|---|---|---|
| Inkjet (MiJia) | Horizontal bands, color skips | Air bubbles in the cartridge after refueling | Remove the cartridge, shake, set back |
| The inkjet (Mi Portable) | Vertical white lines | Dried ink on cartridge contacts | Wipe the contacts with a cotton swab soaked in distilled water |
| Laser (Mi Laser) | Gray stripes all over the leaf | Wear of a photo drum or a non-original toner | Replace the drum or cartridge with the original |
| Laser (Mi Laser) 15000A) | Black vertical lines | Damage to the magnetic shaft in the cartridge | Replace the cartridge (not subject to repair) |
For Xiaomi laser printers, there is one trick: if the strips appeared after refilling the toner, try redistributing the powder inside the cartridge.
- Remove the cartridge from the printer.
- Then, shake it from side to side (not up or down!).
- Install it back and run the test print.
β οΈ Note: In laser printers Xiaomi Mi Laser categorically can not use toner from other brands (for example, HP The composition of the powder is different, and this leads to premature wear of the photoreel.
3. Mechanical malfunctions: when rollers and belts are to blame
If the stripes on the print are accompanied by extraneous sounds (squeaking, crackling) or uneven paper supply, the problem is most likely mechanical.
- π οΈ Paper rollers - wear out or become dirty, because of which the sheet passes unevenly.
- π Cartridge drive belt β stretches over time, which leads to a βshiftβ of the print.
- π§² Carriage position sensor β if it is contaminated, the printer βlosesβ the position of the print head.
To diagnose mechanical problems:
- Open the printer lid and manually move the carriage (for jet models) and it should move smoothly, without jerking.
- Check the rollers of paper submission - they should not have traces of wear or glue from labels.
- Start printing on a blank sheet and watch the movement of the machinery. Any delays or irregularities are a sign of malfunction.
In most cases, mechanical problems are solved by cleaning (rollers, guides) or replacing (belts, sensors). For example, the feed rollers in MiJia Photo Printer can be cleaned with a cotton swab dipped in isopropyl alcohol (not higher than 70% concentration!).

4. Firmware and drivers failures: software causes of bands
Less commonly, but still, there are cases where the stripes on the print are caused by software errors.
- π₯οΈ Outdated drivers β especially relevant after Windows or macOS updates.
- π± Failures in the printer firmware β for example, after an interrupted update by air (OTA).
- π Antivirus conflict: Some security programs block access to printer ports.
How to diagnose a software problem:
- Connect the printer to another device (e.g., a smartphone via Mi Home), and if the bands are gone, it's the software on the first device that's to blame.
- Run the test page directly from the printer bar (without a computer), if the page is clean, the driver problem.
- Check the printer event log in the Control Panel β Devices and printers β Printer properties.
Solutions for different cases:
| Problem. | Action. |
|---|---|
| Outdated drivers | Download the current version from the official Xiaomi website (Support section) β Printers) |
| Firmware failure | Reset the printer settings: Settings β System system β Reset to factory |
| Conflict with antivirus | Add the printer to the antivirus exceptions or temporarily disable the protection |
β οΈ Note: If the Xiaomi printer after updating the firmware stopped printing at all or gives an error E02, Don't try to sew it manually! Contact the service - self-firmware can lead to locking the device at the chip level.

5. Incorrect printing settings: when the user is to blame
Sometimes, the bars on the print appear because of incorrect settings in the driver or application, which is the most innocuous reason, because it is eliminated in a couple of clicks.
- πΌοΈ Incorrect resolution β if set too high DPI For low quality paper, the ink will flow.
- π Paper type mismatch β for example, choosing a βphoto paperβ for a regular A4 sheet.
- π¨ βDraftβ mode β in this mode, the printer saves ink, which leads to pale stripes.
How to set up the print correctly (on the example of Xiaomi MiJia Photo Printer):
- Open the document and select the file β Seal.
- In the Printer Properties section, set: Paper type: Corresponds to loaded (e.g., Normal or Photo Paper). Quality: Standard (1200Γ600 DPI textual, 4800Γ1200 DPI Color profile: sRGB for photos.
Quick print
For Xiaomi Mi Laser laser printers, it's critical to set the toner density correctly. If the value is too high, dark stripes will appear on the prints, if the low one is light: 3-4 (printer-scale).
π‘
Always use the print settings recommended by Xiaomi for your model. For MiJia Photo Printer, they are listed in the manual on page 12, for Mi Laser on page 18.
External factors: humidity, paper, electricity
The strips on the print can appear due to operating conditions that at first glance have nothing to do with the printer.
- π‘οΈ Humidity β if it is above 70%, the paper absorbs moisture and deforms, leading to uneven printing.
- β‘ Unstable voltage β electricity surges cause malfunctions in the printing head.
- π Low quality paper β cheap paper can dust, clog machinery, or have an uneven surface.
Recommendations for elimination:
- π Store paper in sealed packaging, in a dry place.
- π Use a voltage stabilizer (especially for laser printers).
- π For photo printing in MiJia Photo Printer, use paper labeled Xiaomi Photo Paper β it is optimized for the ink of this printer.
If your Xiaomi printer is in a room with high humidity (such as a kitchen), try drying it:
- Turn off the printer and remove the paper.
- Leave it off for 12 to 24 hours in a dry place (such as near a heater).
- Before turning on, check if there is any condensation left on the internal parts.
7.When to contact the service: signs of serious breakdowns
Not all lane problems can be solved on their own, but there are a number of signs that indicate serious hardware malfunctions that require professional repair:
- π₯ The smell of burning when printing - a sign of overheating of electronic components.
- π₯ Persistent errors (e.g, E01, E03) even after resetting.
- π Stripes are maintained after cartridge replacement, head cleaning and firmware updates.
- π§ Mechanical damage (cracks on the body, bent parts).
The cost of repairs in Xiaomi service centers (Moscow, 2026):
| Type of breakdown | Cost (β½) | Duration of repairs |
|---|---|---|
| Replacement of the print head (MiJia) | 3 500 β 5 000 | 3-5 days |
| Repair of the paper-filing mechanism | 2 000 β 3 500 | 2-4 days |
| Photo Drum Replacement (Mi Laser) | 4 000 β 6 000 | 5-7 days |
| Firmware after failure | 1 500 β 2 500 | 1-2 days |
If your printer is warranty, donβt disassemble it yourself, it voids warranty obligations. Xiaomi service centers have special tests for diagnosing striped printing, which allow you to accurately determine the cause without disassembling the device.
β οΈ Note: When contacting the service, take a check and a warranty card. If the printer was purchased on AliExpress or from an unofficial seller, the warranty may not work - check this in advance by phone service center.
