Q2: Can I use the Bentsai printer while it is charging?
Yes, the Bentsai handheld printers support pass-through charging. You can continue to operate the printer while it is plugged into a power source. This is particularly useful for extended printing sessions where the battery life might be a constraint.
Q3: How do I upgrade the firmware on Bentsai B2, B3 or 6105F printers?
Before upgrading, please ensure the printer has at least 50% battery. If power is below 35%, connect to an external power adapter. Follow these steps to upgrade your printer:
- Check Current Firmware Version: On the printer's home screen, go to Device or Maintenance to view your current firmware version. Confirm that it is eligible for the upgrade.

Ink Cartridge Troubleshooting and Maintenance
Q1: Can I remove or insert ink cartridges while the printer is turned on?
Yes, the Bentsai series is designed with a "hot-swap" feature. You can safely remove or insert ink cartridges while the printer is powered on. The system will automatically detect the cartridge change. However, ensure the printhead is not actively printing or moving to avoid any potential issues.
Q2: Can I use third-party ink cartridges with Bentsai handheld printers?
To ensure optimal print quality, reliability, and longevity of your printer, we strongly recommend using genuine Bentsai ink cartridges. Third-party cartridges may not be recognized by the printer's firmware, could cause clogging, void your warranty, or result in inconsistent printing output.
Q3: How to fix the "Ink Box Not Installed" error message?
If you see an "Ink Box Not Installed" error on your screen, even with a cartridge inserted, use the following checklist to resolve the issue.
Troubleshooting Checklist:
- Check the Chip Sensor: Press the chip sensor pins inside the cartridge slot to verify they bounce back normally.
- Clean the Cartridge Chip: Gently clean the ink cartridge's metal chip with an eraser or lint-free cloth to remove any dirt or residue.
- Inspect the Chip: Check if any parts of the electrical connections on the cartridge chip are missing or damaged.
If the issue persists after completing these steps, please contact support@bentsaishop.com for further support.
Q4: How to fix low ink output or clogged print-heads after long-term storage?
If your printer has been stored for a long period without use, the ink in the nozzles may dry out, leading to poor print quality. Follow these steps to restore performance.
Troubleshooting Steps:
- Perform Automatic Cleaning: Navigate to the maintenance menu on the printer and select "Head Cleaning." Repeat this 2-3 times if necessary.
- Check the Test Print: After cleaning, print a test pattern to evaluate the nozzle performance.
- Clean Manually: If automatic cleaning fails, use the following method.
- Prepare a Cloth: Fold a lint-free cloth and dampen it slightly with a small amount of isopropyl alcohol or cleaning solution.
- Wipe the Nozzle: Gently press the printhead nozzle against the damp cloth for 3-5 seconds to allow the cleaning solution to dissolve dried ink.
- If the problem continues, contact us for further support.
Warm Tips for Maintaining Ink Cartridges:
Before Printing: Wipe the ink cartridge nozzle with alcohol and a facial tissue, and shake the ink cartridge before use.
After Printing: Clean the ink cartridge again. When not printing, remove the ink cartridge from the printer and install the protective clip on the cartridge to prevent ink from drying.
Differences and Purchases
BENTSAI 6105 series include the 6105B2, 6105B3 and 6105F. They share some common features such as the same print height of 2.5mm to 12.7mm, up to 600 DPI resolution, and can print on porous and non-porous surfaces such as cardboard, wood, plastic, glass, and metal.
However, they are slightly different as well.
Q1: Differences between 6105 series models
6105B2: Entry-level model. Supports 1–5 lines of text, QR codes, barcodes, and logos. Uses BT-2560N (water-based) or BT-2580P (solvent) cartridges. Does not support variable data printing or file import/export.
6105B3: Advanced model. It shares the same print height and ink types as B2, but adds variable data printing and the ability to import/export txt and csv files. Uses the same BT-2560N/BT-2580P cartridge series.
6015F: This is the newest model that upgraded from model B2/B3. It features new code types (ITF-14, GS1-Datamatrix), a new ink system (BB21/BB22 series), faster touchscreen response, enhanced stability, and support for variable data printing and file import/export.
Q2: Can I purchase B2 and B3 now?
No, the BT-HH6105B2 and BT-HH6105B3 are no longer available. They have been replaced by the BT-HH6105F, which runs smoother and has more features. We recommend going with the 6105F.
