Hello Grade,
The cartridges are packed into the carton manually by a person.
In addition to the visual inspection by the person packing we are also going to check weigh each carton by using a digital weight scale – it will identify 1 missing cartridge.
Then for the next 2 shipments each carton will be weighed for correct weight/count by another person. Plus the Baroda Quality Manager will also make random checks throughout production to ensure correct weight/count, if one cartridge is found missing we will rework the full order by checking each carton again.
I appreciate that this issue has had a lot of focus from your Customer and we will make good so you do not have to worry about this in the future.
