6.2 COVER FEEDING PROCESS
6.2.1 PRINCIPLE OF OPERATION
Inserting covers
Cover On is selected in the booklet maker UI (operation panel).
Empty bin sensor (CF-Q31) detects that sheets are loaded. The operator must
press down the bin to load covers. The bin automatically positions the covers
against the feed roller. Blower CF-M17 / M18 blows separation air into the stack.
If sheets have been run previously, the cover feeder is now in ready mode.
If sheets have just been loaded, feed motor (CF-M15) and drive motor (CF-M16)
start and transport the first sheet past sensor (CF-Q30). When paper positioning
sensor (CF-Q32) is activated the feed and drive motors runs a short distance lon-
ger and then stops. The cover feeder is now in ready mode.
During automatic operation the copier sends a start signal, a manually fed set
needs to insert a cover or the single feed mode is selected.
Feed motor (CF-M15) and drive motor (CF-M16) starts. This drives the cover into
the booklet maker. The feed motor (CF-M15) uses an encoder and the current
format to determine when the trailing edge leaves the feed motor rollers. When
this happens the feed motor stops. The drive motor monitors the paper positioning
sensor (CF-Q32) and when the trailing edge of the cover leaves this sensor, the
drive motor (CF-M16) lowers its speed (unless already running at low speed as
when running an A3 job). When the speed of the drive motor (CF-M16) is lowered
the feed motor starts and repeats the initial cycle.
