A switch to 9-cpm copying mode is made after delivering the 19th copy in a continuous
copying job.

Controlling the Copying Speed in Multifeeder Mode
The machine does not possess a copy paper width detecting function and, therefore, the tem-
perature of the ends of the fixing assembly increases when copies are made continuously on paper
narrower than A4/LTR.
When the multifeeder is used for continuous copying, a delay is initiated after picking up the
19th sheet so as to increase the sheet-to-sheet distance for the sheets that follow, controlling the
copying speed to 9 cpm.
If the copying speed is controlled (to 6 cpm) by a mechanism to prevent overheating of the
copyboard, this control will not be executed, and moreover if the temperature of the copyboard
increases during 9-cpm control, 6-cpm control will be initiated.
