2–4 CX20/CX30/CX34 Service Manual
The printer is located in a housing on the right–hand side of the machine,
accessible through a removable drop–down door (lockable on the CX30 TK). It
dispenses printed tickets through a ticket slot at the front.
The CX20 unit has two 20–character, vacuum–fluorescent, numeric displays,
one on the vendor side of the unit and one on the customer side. These
displays present numeric and annunciator information only. A small liquid crystal
display (LCD), capable of presenting alpha and numeric information (16 digits),
is positioned below the ticket slot to provide the operator with prompts and error
messages.
The CX30 unit has a head–up display assembly. This comprises two
alpha–numeric displays mounted on top of a double column at the customer
side of the unit. The head–up display presents information to the customer and
vendor by way of two display screens. Operator prompt information and error
messages are presented only on the vendor side of the display assembly. The
CX30 does not have an LCD.
