SN Code is not working - FAQ
Important Note: When you only need to remove the ink cartridge for maintenance/cleaning, you do not need to re-enter the SN Code! After cleaning, simply reinsert the ink cartridge into the printer.
1. Verify your SN Code is entered correctly
As shown in the image below, the letters and numbers on the yellow dotted line represent the SN Code.
2. Check your ink's expiration date
To ensure food safety, all Evebot edible inks have expiration dates:
- Shelf Life (Unopened): 12 months from production date
- After Opening: Use within 6 months
The production date can be found on the ink cartridge label just below the SN Code, formatted as YYYY-MM-DD.
Desktop Coffee Printers will track and calculate ink expiration, displaying a replacement reminder on screen before expiration.
3. Confirm the ink is not depleted
4. Only enter new SN Code when replacing ink
Do not enter a new SN Code unless you're installing a brand new ink cartridge. Once activated, the Coffee Printer records the ink as "used" and this status cannot be reversed.
