OHP-PTH Set of ITB clean transp threshold value
Lv.2 Details When a large number of transparencies is fed, surface active agent
which coats the surface of an transparency adheres to the ITB, and
consequently the transfer efficiency is lowered, causing an image
failure. After feeding a certain number of transparencies, a patch
is formed on the ITB, and the ITB Cleaning Blade scrapes it off
together with surface active agent.
This setting is used to set the threshold value for the number of fed
transparency which is the condition to execute ITB cleaning.
