The Phomemo M120 is a portable label printer designed for various labeling needs. It is primarily used for printing labels from a mobile device via a dedicated app, "Print Master."

Function Description

The M120 printer is a thermal printing device, meaning it does not require ink cartridges, using heat to produce images on special thermal paper. It supports different types of consumables, including pre-cut paper, black mark paper, and continuous paper, allowing for flexibility in label creation. The printer is capable of generating both 1D and 2D barcodes, making it suitable for inventory management, shipping, and retail applications.

The device features a simple interface with a screen, a power button, and a feed button. The power button serves to turn the device on/off with a long press (3 seconds) and to switch between home menu options with a continuous click. The feed button has multiple functions depending on the type of paper being used. For pre-cut or black mark paper, a single click will take a label, position it, and adjust it to the beginning of the next label. For continuous paper, a single click will feed the paper, and releasing the button will stop the feed. A long press of the feed button will automatically return the user to the main menu interface. Continuous clicking of the feed button allows switching between sub-menus.

The M120 also includes a reset hole and a USB port for charging and data transfer. The paper exit is located at the top of the device, and a rope hole is provided for portability.

Usage Features

Paper Roll Installation: Installing a paper roll in the M120 is a straightforward process. First, the device is powered on by long-pressing the power button for 3 seconds. The paper compartment cover is then opened by holding both sides of the cover near the paper outlet and lifting it upwards. The label paper mounting bracket is removed from the compartment. The left baffle of the bracket is removed, the label paper roll is inserted with the printing side down, and the baffle is pushed back to the right to secure the roll. The installed label roll holder is then aligned with the card slots on both sides of the paper compartment and placed inside. Finally, approximately 15mm of paper is pulled out above the paper exit, and the paper compartment cover is closed. The printer will automatically feed the paper to position the gap of the label paper, indicating that the installation is complete. It's important to note that after the first operation or whenever consumables are replaced, the printer will automatically feed the paper to ensure proper label positioning and prevent incomplete, missing, or non-aligned prints.

App Download and Connection: The M120 operates in conjunction with the "Print Master" app, which can be downloaded by scanning a QR code provided in the manual or by searching for "Print Master" in app stores (Google Play or App Store). To connect the printer to the app, users must first ensure that GPS is turned on for Android mobile phones due to system requirements for geographic location access during connection. The app is then opened, and the user clicks to search for the device. Once found, the connection can be established immediately. It is crucial that the printer is turned on and Bluetooth is enabled on the mobile phone during the connection process.

Label Creation and Printing: The app offers two main methods for printing labels: creating a new label or selecting an existing template.

New Label Creation: Users can click "New" in the app to customize the label size and paper type. This involves setting the label name, width, height, and print direction. After customizing, text can be input by clicking the "T" icon. Once the label is edited to satisfaction, clicking "Print" will initiate the printing process.
Template Selection: Alternatively, users can click "Label" in the app to browse and select from various pre-designed label paper templates, such as "Round label." After selecting a template, text can be input, and the label can be printed. It is important to select a matching template to avoid undesirable situations like half-printed labels.

Editing Functions within the App: The "Print Master" app provides a comprehensive suite of editing tools to customize labels:

Text: Insert and edit text, adjusting size, typesetting, and fonts.
Icon: Insert various cute icons to decorate labels.
Border: Choose from different borders to enhance label aesthetics.
Picture: Insert and print images.
Time: Insert the current date and specific time.
Scan Code: Scan existing codes to quickly identify text content for QR codes.
1D Code: Insert one-dimensional barcodes by entering information, which then automatically generates the barcode with adjustable layout.
QR Code: Insert QR codes by entering information, which then automatically generates the QR code with adjustable layout.
Line: Insert dashed or solid lines.
Shape: Insert round or square shapes.
Excel: Support table import for quickly generating printable lists.
Recognize Text: Recognize text from a picture.
Templates: One-click editing/printing of more scene label templates. App functions are subject to updates, so users should refer to the actual app for the latest features.

Maintenance Features

Troubleshooting Common Problems: The manual provides guidance for common issues users might encounter:

Paper Not Detected: If paper is fed but not detected, users should check if the paper is correctly placed on the right side of the printer, pulled out slightly from the outlet to sit between the sensors, and if the bin cover is closed.
Printer Unresponsive: If the printer doesn't respond after a long press of the power key, it might be due to low power. Charging for at least half an hour and then restarting is recommended.
Automatic Shutdown: If the printer shuts down automatically, check the app's automatic shutdown time settings or if the power is too low, requiring a timely charge.
Charging Issues: If the printer refuses to charge, try charging for at least half an hour, performing a manual reset using a pin in the reset hole, checking if the charger is 5V-1A or 5V-2A, replacing the charger, or contacting the dealer if issues persist.
Blank Prints: If prints are blank, ensure the paper roll is installed with the correct printing side facing down and to the right. Also, verify that "label paper" is correctly selected in the printer's display menu.
Fuzzy Prints: Fuzzy content can be caused by an expired label roll or foreign matter. Users should check the label roll's storage period, clean the printing area with an alcohol swab to remove dirt from the print head, or replace the roll.
Skipped/Incomplete Prints: This can be resolved by cleansing the printer thermistor and paper outlet, reinstalling the paper roll bracket, and pressing the paper feeding key once to allow the printer to recognize the paper gap. Additionally, verify that the paper size and software print template match.
Paper Feeding/Printing Issues: If the printer doesn't run smoothly or experiences feeding failures, check if the paper roll bracket is too tight or stuck. There should be approximately 1mm of gap between the roll and baffles for smooth feeding. Wiping the printing area and paper outlet with an alcohol swab and checking for stickiness can also help.
Multiple Mobile Phone Connections: The printer can only connect to one mobile phone at a time. To connect with a different phone, the current connection must be disconnected first.

Warranty Information: The M120 comes with a one-year warranty from the date of purchase, offering replacement/return support. Users are advised to keep the warranty card in a safe place for future reference. The manual itself is carefully checked, but for any printing errors or misunderstandings, customer service should be consulted. Updates to the supporting software will be compiled into new versions of the manual without prior notice.
