Bentsai B10 FAQs
Q: On which material surfaces is Bentsai B10 not suitable for printing?
A: The B10 may not print well on glossy surfaces like polyester paper and POM plastic, as ink adhesion can be weak. Also, dark-colored ink (e.g., green) may not show up on dark surfaces.
Q: How many characters can one Bentsai B10 ink cartridge print?
A: One 42ml cartridge prints up to 2 million characters.
Q: How do I fix blurry prints on the Bentsai B10?
A: Blurry prints are usually caused by a clogged or dirty nozzle. Try these steps:
- Perform Automatic Cleaning: Run a nozzle cleaning cycle in the app (if available).
- 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 issue persists, try a fresh ink cartridge.
Q: Can B10 ink be washed off?
A: Once dry, the solvent-based ink is waterproof but not permanent.
- On non-porous surfaces (glass, metal, plastic), ink sits on top and can be removed with alcohol or a scraper.
- On porous surfaces (wood, fabric, paper), ink soaks in and becomes permanent – it will not wash or wipe off.
Note: The B10 cannot print on oily or greasy surfaces – the ink will not adhere properly and may diffuse. With multiple washes or prolonged friction, the ink may gradually fade even on fabric.
The Bentsai B10 is a versatile, pocket-sized printer that fits both small business workflows and creative projects. With easy app control, fast-drying ink, and support for a wide range of surfaces, it's a solid choice for on-demand printing.
