1. Charge Your Printer

Before using your printer for the first time, make sure it is fully charged. Connect the provided charging cable to your printer and plug it into a power source until the battery indicator shows it's fully charged.

2. Install the Ink Cartridge

Open the cartridge compartment following the directions in the user manual. Insert the ink cartridge securely and close the compartment. Ensure that it clicks into place to avoid any printing issues.

3. Perform a Print Test

Conduct a test print on a piece of paper to ensure the ink flows smoothly and the printer functions correctly. This step verifies that the handheld printer and cartridge are properly aligned and ready for use.

4. Adjust Print Settings

After the initial print test, you can adjust the print settings based on the result to better align with your specific needs. This includes modifying the print resolution, direction, grey level, and print mode among other settings. Adjustments can be made directly via the printer’s touch screen, allowing you to fine-tune the output until you achieve the desired quality and effect.

5. Prepare the Object to be Printed

Ensure the object you want to print on is clean, dry, and positioned correctly. Depending on the object's shape and size, you may need to adjust its placement for optimal printing.

6. Edit Content to be Printed

You can edit the content directly on the printer’s touch screen or create your content on a computer and save it to a USB drive. If using a USB drive, ensure the content file is in a supported format (JPG, PNG, BMP, CSV), doesn’t have any blank space in file name and adheres to the printer's size limitations.

7. Insert USB Drive and Print

If you're printing from a file, insert the USB drive into the printer. Select the correct file and confirm the settings meet the printer’s format and size requirements.

8. Start Printing

Depending on the nature of the object, choose to use the assisting tools provided:

1. Roller: Helps in achieving more stable prints, ideal for even surfaces.
2. Positioning Plate: Assists in getting better results on narrow and curved surfaces.

Before choosing an ink cartridge, it's important to understand the ink types for Bentsai handheld printer: water-based and solvent-based ink. The table below outlines their key differences to help you choose the right one for your printing needs.

● Water-based ink is suitable for printing on absorbent materials in indoor environments—commonly used in packaging, warehousing, and labeling on paper or wood. It's ideal for users who work with cartons, tags, or wooden crates in relatively dry, clean settings.

● Solvent-based ink works on both absorbent and non-absorbent surfaces, making it better suited for industrial production, logistics, electronics, or pharmaceuticals where plastic, metal, or glass surfaces are common, and durability and water resistance are required.

The above print count test was conducted using a 42ml ink cartridge containing 1.14 million ink dots, with printing parameters set at 300 DPI and a grayscale level of 7.  For further assistance or inquiries, please contact us.

Bentsai handheld inkjet printers are built to perform reliably in a variety of environments.
They support a working temperature range of 5°C to 35°C (41°F to 95°F) and a relative humidity range of 10% to 80%.

These conditions cover most indoor and outdoor use cases, including printing on construction materials, cables, pipes, and other surfaces commonly found in warehouses, factories, and job sites.

Selecting the right Bentsai handheld printer starts with identifying your specific application needs. Key factors to consider include: printing height, material compatibility, availability of variable data printing and photoelectric sensor connection, etc.
