SPECIFICATIONS
INDEXING AND NON-INDEXING MODELS
Universal Non-Porous Conveyor Line Printers are available in both indexing and non-indexing models.
Indexing coders contain a print drum spring return mechanism
which provides print registration capabilities when carton printing
(see Figure 1). As the trailing edge of a carton passes the coder,
the print drum automatically rotates back to the same starting or
“home” position. There must be adequate space between cartons
at any given line speed for this mechanism to work properly. Print-
ing with an indexing coder will allow the imprint on each carton to
be registered in the same position relative to the leading edge of the
carton. The code will repeat every 18" down the length of the car-
ton.
Non-indexing coders have print drums which simply rotate on
bearings with no spring return mechanism. These coders are nor-
mally used for web printing applications where the print drum stays
in contact with the web at all times. If used in carton printing appli-
cations, when the trailing edge of a carton passes the coder, the
print drum rotation stops at a random position. When the next car-
ton engages the print drum, the code will begin printing at a random
position relative to the leading edge of the carton and repeat the
code every 18" down the length of the carton.
Note: Due to the symmetrical design of the Inking System on the Non-Porous Conveyor Line Printer, the Right
Hand and Left Hand mounting configurations are field convertible. Due to the location of the ports for the 4 Oz.
Reservoir Ink Cartridges, Top Mount and Side Mount orientations cannot be field converted and must be properly
specified when ordering.
MOUNTING CONFIGURATION
The mounting configuration of a coder is determined by how the machine is designed to be mounted in relation to
the product and its movement. All references to mounting configuration are made as though you are viewing the
production line with the product moving away from you. Universal Conveyor Line Printers are available from the
factory in 4 different mounting configurations as shown in Figures 2 and 3.
