18-4. Cleaning Web Take-Up Mechanism
●
The Cleaning Web wound around the Web Roller is taken up by the Web Take-Up
Roller which is driven by Cleaning Web Drive Motor.
●
Cleaning Web Drive Motor is turned about one turn in every 7 to 14 copies made to
take up the Cleaning Web.*
* The length of the Cleaning Web taken up per one revolution of the Cleaning Web
Drive Motor varies depending on the amount of Cleaning Web which has already
been taken up. That is, in the beginning of a new roll of Cleaning Web, a shorter
length of web is taken up per one revolution of the Cleaning Web Drive Motor, as
there is a very little amount of web taken up by the Web Take-Up Roller. The more
the web is taken up, the longer the length of web taken up. The copier therefore
refers to the count of the “Web Roller” counter and turns the Cleaning Web Drive
Motor one turn, in the beginning, for every 7 copies made and, at the last stage,
for every 14 copies made, thereby ensuring that a given amount of web is taken
up for each copy.
●
The Web Take-Up Roller Shaft is provided with a Clutch Spring that prevents the
roller from turning backward, thereby preventing the Cleaning Web from developing
slack or wrinkling during take-up.
● On the right side at the front of the Fusing Unit, there is a gauge provided showing
the approximate amount of Cleaning Web still available for use. It eliminates the
need of removing the Cleaning Web Assy to check for the amount of web.
