● Use a cable whose outside diameter is within the specified range. Securely tighten the lock nut 
at the lead-in port. 
In addition, do not bundle cables of weak and strong electric systems inside or outside the unit, 
in order to minimize the influence of noise from strong electric system signals (connection 
signals to the power supply and terminal block TB5) on weak electric system signals 
(connection signals to terminal blocks TB1, TB2, and external communication connectors). In 
particular, do not bundle the print target detector, print stop signal, power supply, and ready 
signal cables, or do not route them in the same duct. 
 
[Method for connecting the cable to the lead-in port] 
The procedure for connecting the cable to the lead-in port is described below. 
 
 
   
(1)  Remove the set screw, and remove the 
cable seal block from the unit. 
(2)  Divide the cable seal block. 
(3)  Wrap the seal around the outside of the 
cable as shown above. At this time, wrap it 
so that there is no gap between the seal and 
(4)  Put the part where the seal was wrapped 
into the cable seal block, tighten the set 
screw, and install it to the unit. 
(1)  Remove the lock nut. 
(2)  Insert the cable as shown above. 
(3)  Tighten the lock nut.   
Tighten it with a tool securely.
