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.
