Q5: Long-term placement results in less ink output or no ink output from the print-head. What should we do?

You can try the following methods to solve this problem:

1. Take out the ink cartridge and shake it vigorously to confirm whether there is still ink. If there is no ink, please replace the ink cartridge.

2. Enter the UI device maintenance interface and click "nozzle cleaning" to clean the nozzle for multiple times;

3. Wipe the nozzle with a soft paper towel and alcohol.

If the above actions cannot improve the situation, please replace the cartridge before use!

 

Q6: My printer states “ink box not installed” when the ink cartridge is inside, what to do?

Please run a quick troubleshooting by following these steps.

1. Press the pins on the cartridge container to check whether they can bounce back normally.

2. Check whether there is any dirt on the ink cartridge's chip before installing; if yes, please gently clean it with an eraser or lint-free cloth.

3. Check whether any parts of the electrical connections on the ink cartridge are missing before installing.

If all seems normal and your printer still cannot detect the ink cartridge, please contact BENTSAI Customer Support at bentsai@ptstsb.com for assistance.
