54 Finisher unit explanation ENWW
1 Operation
a Staple
Upon completion of the alignment
operation by the alignment plates, M709
and M714 (stapler /R and /F) initiate the
operation of pushing the needles into
the paper. After a predefined time
period has elapsed, M710 and M715
(clincher /R and /F) start bending of the
needles. The stapling operation finishes
when PS732 (clincher hp /R) and
PS733 (clincher hp /F) as well as
PS730 (stapler hp /R) and PS731
(stapler hp /F) detect the clinchers and
the staplers at their home positions (off
to on).
b Staple clogging detection
During the stapling action, if one or
more signals from PS730, PS731
(stapler hp /R and /F), PS732 and/or
PS733 (clincher hp /R and /F) do not
return to on within a predefined time
period since they have changed to off,
the MFP recognizes that a needle
clogging error has occurred. In this
case, M709, M714 (stapler /R and /F),
M710, and M715 (clincher /R and /F)
initiate reverse rotations to return the
staplers and the clinchers to their home
positions.
c Cartridge detection
SW701 and SW703 (cartridge /R and
/F) in the staplers detects whether the
cartridges are properly installed or not.
If the cartridge is not found or is
considered to be improperly installed,
an error message will be displayed on
the LCD of the MFP.
d Staple detection control
When SW702 (staple /R) or SW704
(staple /F) detects the state of no needle
remaining staples, an error message
will be displayed on the LCD of the MFP.
