The following table illustrates the message exchange in response to a new paste cartridge being
inserted into the carrier and the tag being read successfully:
Comments Host Equipment Comments
Host acknowledges event
Host checks whether current
material ID is suitable for the
current product.
Host requests the equipment sets the
SCValidatedMaterial EC, ECID 44,
to the value just verified
If the item ID is appropriate for the
current product the host requests the
equipment sets the value of the
MaterialVerifState EC, ECID 43, to
Valid otherwise the value is set to
Invalid
S6F12 -->
S2F15 -->
S2F15 -->
<-- S6F11
<-- S2F16
<-- S2F16
System power up after covers opened.
The equipment successfully reads a new
value for the Material ID and sends to host
using CEID 40201 configured with a report
containing SVID 1047.
Equipment sets ECID 44 to the specified
value and sends the ack message.
Note if the host fails to set the EC value or
another cartridge is loaded prior to the
verification response being received the
attempt to set the verification state will fail
with an EAC value of 65 indicating the
current UID is not synchronised.
Equipment updates the material verification
state model and sets the MaterialVerifState
EC to the required value.
Note the host must set the verification state
within the time period specified by the SC
Verif Timeout configuration parameter
otherwise the state machine will transition to
the error state and refuse any subsequent
updates from the host

10.5 Material Verification
The transfer material can be configured for verification when the applicator is either a paste dispenser
or refillable ProFlow device.
If the applicator is a paste dispenser the equipment reads the unique identifier contained in the RFID
tag. The tag is affixed to the material cartridge.
If the applicator unit is a refillable ProFlow device the equipment reads the unique identifier of the tag
fixed to the ProFlow head and also a sequential number stored in the data area of the tag. The
sequential number is written to the tag by an external device when the ProFlow head is recharged with
material. The unique identifier and sequential number are concatenated to produce an ID unique to that
head and material charge.
The following table lists the equipment variables associated with material verification. Full
information about these equipment variables can be found in section 7.
NAME TYPE ID DESCRIPTION
MaterialVerif EC 42 An equipment constant used to specify whether the
material verification feature is enabled or disabled
MaterialVerifState EC 43 An equipment constant used to drive the material
verification state machine. This is a model shared
between the host and the Printer. It is used to synchronise
verification activity.
SCValidatedMaterial EC 44 An equipment constant used to store the UID of the
material last validated by the host. The host should set
this value prior to attempting to set the material
verification state
Material RFID Tag Read
Failed
CE 40200 A collection event used to notify the host that the tag
read attempt has failed
Current Material UID
Changed
CE 40201 A collection event used to notify the host that the UID of
the currently fitted material has changed
CurrentMaterialUID SV 1047 A status variable that normally represents the unique
identification value of the currently loaded material
cartridge or ProFlow charge. However in the event that
the tag read fails it is set to one of the following values:
“0” – Cartridge not detected in dispenser
“-1” – Cartridge present but unable to detect the RFID
tag.
“-2” – Tag read failed due to hardware error.
ValidMaterialUID SV 1048 Represents the unique identification value of the last
validated material cartridge or ProFlow charge
