Hmm my friend use led uv ink in 1500w for more than 2 years already .... never had any clogs ....and was not aware of cleaning caping station too:) so seems like it is not as bad.... of course on my L1800 I hade to replace dampera anb tubes plus caping station tubes to solven friendly and uv blocking ones..... otherwise it seems to works fine .... i have tested some uv ink under day light and it not cure... cure well when strong uv lamps is used close to it ....
