Rechargeable
Transfer Head
The rechargeable transfer head option is fully compatible with the ProFlow
hardware and offers the alternative of using ProFlow without changing the
format new material is supplied in, ie material not in ProFlow cassettes can still
be used with ProFlow.
Elements of the rechargeable transfer head comprise:
• Conditioning Chamber (single or dual chamber)
• Diaphragm Retainer
• Diaphragm
• Filling Ports (3 in number, 1 for 150mm transfer head)
• Retention System
• Cover
• Recharging Nozzles (2 in number)
Figure 1-13 Rechargeable Transfer Head
The rechargeable transfer head is constructed in much the same way as the
cassette transfer head. The main difference being that a diaphragm, held in
position by a diaphragm retainer, replaces the cassette. The transfer head is
fitted to the pressure mechanism unit in the same way as the cassette transfer
head unit, (Cassette Transfer Head section of this chapter refers).
Print material is initially filled into the paste chamber through the stainless steel
grid of the retention system (single conditioning chamber units), or the nozzle
system of the dual conditioning chamber type. General recharging is performed
by using the 3 filling ports sited on the front side of the transfer head. The filling
ports are sealed using bayonet connector caps.
NOTE
For detailed procedures of print material filling refer to the Consumable Replen-
ishments chapter of the machine manual or the ProFlow Best Working Practices
guide (DEK Part No. 171280).
