The printer uses RFID technology to automatically identify the material

cartridges. For this purpose, an RFID module is part of the printer hardware.

Tampering with this module will render the printer inoperable and may void

Objet warranties and service contracts.

Tips about replacing cartridges:

•You can replace material cartridges either before or during printing.

•You can replace partially used cartridges to avoid the need for replacing

them during printing.

•You can load partially used cartridges, as long as they contain more

than 100 grams of material.

You can stop and later resume printing from either the Connex printer

the printer interface, you can only resume printing from the printer interface.

You should carefully plan printing models with different model materials to

avoid unnecessary waste of the material loaded in the printer. The amount

of material flushed depends on the flushing cycle chosen and if you are

replacing one or both cartridges.
