white spots in prints

It still looks like contaminated media. Did you try another media as suggested in the other thread?

 

Hello we were having the same issue with our hp 360 and IJ35C-20 media. We thought it was the media at first but then we thought it was something in our environment. After lots of tests and different media’s we came to the conclusion it was the media. We have had 2 bad rolls from 2 different suppliers at pretty much the same time but all is good now after we got some newer rolls

 

Have you done a cleaning of the curing tunnel?

Typically greasy spots are due to reduced airflow and heat. If the holes are plugged the air can't wick away the moisture from the latex ink.

 

I'm having the same issue with black not drying. Can you explain or point us in the direction of where/how to clean the "curing tunnel"? Thank you!

 

It is part of service maintenance kit 3, but depending on your print environment the cleaning needs to happen more frequently. you need to disassemble the curing tunnel to clean the airflow plates on the top side, its pretty laborious.

 

Is this something that would be covered under a warranty to have a tech come out and handle?

 

no its not a warranty item as its a general service item. Our local tech company charges us $250 to do the cleaning or $450 for the full SMK3 service.
