Finisher Y-1 on IRC3080i stapling problem

[bartman]

Hello all. I am refurbishing a IR3080i with finisher Y-1 and when stapling sets, one piece of paper will be out of alignment in stapled set. When the paper is partially coming out of the finisher to be pulled back into position for stapling, a sheet will be pulled back in crooked and stay that way once stapled. Thx for your thoughts.

see------------------attached TP08 230 pdf.
Consult technical publication TP08 230 for information to minimize skewed sets of paper.
On page five of the publication there are instructions for determining the down position of the swing guide.
An alternate procedure uses a spring gauge to adjust the down pressure of the swing guide.

Minimizing Skewed Stapled Sets in Finisher -
Alternate Procedure:
Prepare a 20lb letter size sheet of paper with a punch in the short edge of the paper. This will be with for a spring gauge.
a) Turn off the imageRUNNER.
b) Set finisher controller pcb bit 1,2,5,7 & 8 to 'on'.
c) Turn on the imageRUNNER.
d) Press switch 103 once to raise the swing guide.
e) Place letter paper in the swing guide path in the landscape direction.
f) Press switch 103 once to lower the swing guide.
g) To apply more pressure press switch 102 (each press = .2mm), to lower pressure press switch 101 (each press = .2mm).
h) Adjust the pressure so that the paper begins to pull out at 200 to 300 grams of pressure.
i) Press switch 103 once to lock in the adjustment. Turn off all dip switches and reboot the machine.

If a spring gauge is not available, adjust the down position so that the sheet of paper has a slight drag when pulled away from the swing guide.

Thank you Teckat. IMG_0217.JPG The finisher rom version is 8.01 which appears to be newer than the tech pub mentions. The spring is not missing. I have tried adjusting pressure every step from loose to tight and cannot keep this from happening. At a loose setting I get something close to what the tech pub shows. At a tight setting I get the even overlap. This happens even when not stapling. The first set comes out fine. The second copy of the next set, while the finisher is getting ready to eject the stack underneath,comes out overlapped. Thank you for any other information. Bart

it's all about hold and ejection timing

Canon has tried may fixes for this skew issue on their finishers----frustration is part of the job
on the 5180 finishers which has a similar issue>>> see below
one thing to look at >if u know how to remove the covers over the stack ejection area( see picture in pub) there is a sensor attached to a metal plate> the cut out in plate sits over a small bib (making plate not adjustable)

plate.JPG
u can sometimes on a trial & error test experiment bend the plate out/or in a little to change the timing of hold and ejection/ some techs wedge a small piece of paper to change angle (timing for flag reaction to sensor)
this adjustment works about 80% of the time

Re: Finisher Y-1 on IRC3080i stapling problem

It seems like it only happens when there is a downward curl to the paper. After the first stack is done(before ejection) the first copy comes out on top of the first stack and then, when the second copy comes out it seems to have a timing change(only with the second sheet) like maybe the lead edge is catching on the first sheet due to the different angle of the stack underneath it, then the rest of the stack comes out fine. If I turn the paper over in the cassette the problem gets better. If this finisher was able to staple and eject before starting the next stack then there would be no problem.

is there a buffer pass E-2 & puncher installed

are u using 20lb paper /Curl when printing / copying on 20# paper.
Adjust Copier/Option/Body/FN-ENTMP = (-4)
Adjust Copier/Option/Body/TEMP-TBL = (-2)
this will minimize the curl experienced on lower weight media.

if so 24/28lb is better/

also think there is a curl adjustment under additional functions ( not sure under which settings

As teckat said if you have slight paper curl you will get this fault.

I advice my customers to use 100GSM for long staple runs then the finisher runs perfectly.
