MASTER FEED
C262/C265 6-48 SM
Master Buffer Mechanism
To minimize master processing time, the master is stored in the master buffer duct
[A] after the thermal head transfers the image to it. The stored master is fed out
from the duct when the drum reaches the master making position after master
ejecting.
The master buffer duct is located under the master feed path. A two-level chamber
inside the duct can hold a sufficient length of the master for A3 printing.
As soon as master making starts, the three master vacuum fans [B] start turning,
creating suction to guide the master into the duct [A]. At this time, the master feed
control roller has already caught the leading edge of the master. This roller does
not start turning until the drum reaches the master making position and the master
clamper opens.
The master is fed while the thermal head writes the image on it. With the leading
edge of the master stopped, the suction guides the fed master into the master
buffer duct and stores it as shown in the above diagram.
When the drum comes to the master making position, the master feed control roller
starts turning and feeds out the master that is stored in the duct.
The master buffer fans [C] provide air to make sure that the master does not stick
together in the master buffer duct.
