4.18 Check on Exhaust Duct dripping 
 The exhaust contains the vapor of makeup and it will be liquefied when cooled down.   
 Depending  on  the  IJP’s  installation  environment,  there  will  be  a  case  that  there  is  a  big 
difference between IJP’s inside temperature and the operating temperature.   
 When IJP is installed or when IJP is serviced at periodical maintenance, please check the 
items below: 
 
(1) Is there any wiring routed around the exhaust duct, such as the power cord, the electrical 
signal wirings, etc.? Should there be dripping the wire/cable coating may get cracked.   
 Please reroute the wiring and call customer’s attention. 
 
(2) Is there any track of the dripping?   
 Please propose a tray for dripping to customer.   
 There  may  be  a  possibility  that  the  ink/makeup  was  supplied  to  the  ink/makeup 
reservoir more than needed and it overflowed from the reservoir’s vent and ran to the 
exhaust duct. Please call customer’s attention.
