Model 750 “Core” Printer: Main Chassis Assembly

The Series 700 printer operates with a unique system that allows for printing and
presentation of the ticket, without allowing for ticket removal during printing. The
ticket remains out of the reach of the user until all printing is complete. The perforation
is located at a tear bar. Only in that position is the ticket protruding from the bezel
and the perforation easy to tear. Even if the user removes the ticket before the ticket
is completely presented, there will be no disturbance of the graphics as all printing is
complete. The following ticket will then proceed to the correct printing position,
unaffected by the premature removal. This system requires a specific ticket length and
a Black Dot/Top of Form indicator in a precise location for presentation to work as
described. Both of these features keep the ticket in the proper locations for printing
and separation. Any changes to these features require consideration of the presentation
scheme. The benefit of the Model 750 is to allow for the entire printer and Ticket Supply
Box to be removed through a 4.68 by 2.38 inch opening in front of the printer.
