CARTON PRINTING
Universal Non-Porous Conveyor Line Printers are designed so the frame of the machine will pivot on the mount- ing column. This allows the print drum to deflect, or swing, on contact with the leading edge of the carton a maximum of 2". It is recommended that cartons be aligned between guide rails with no more than 1/4" clearance on each side as shown in Figure 40. This should allow ample clearance for cartons and protect your printer from damage.

In most applications, installation of the printer can be accomplished by attaching the mounting bracket to the side rails of the powered conveyor using two 3/8" machine bolts. The printers should be mounted as close as possible to the end of the guide rails to ensure that proper carton alignment is maintained at the printing station.
Before tightening the mounting bolts, check alignment of the print drum. It is very important for proper tracking that the top of the print drum is parallel to the top of the conveyor (Figure 41) and the side of the print drum is parallel to the side of the carton (Figure 42). Once this alignment has been achieved, tighten the mounting bolts.
