NOTE: When running smaller stapled sets (15 sheets or less), limit the quantity to 100 maximum. Unload the stacker after each
quantity is completed.
Set BFM Registration Values
Paper registration at the BFM is impacted by curl. Follow the steps below to improve paper registration quality at the BFM for each BFM
on the system. However, it is recommended that you first resolve curl issues with the IOT decurler or, if available, the Sheet
Enhancement Module setting (see
Adjusting the
1. Select [Print Manager: Stacking tab].
2. Right-click on one of the finishing devices and select [Stacker Limits]. The Stacker Limits window displays.
3. If this is a dual BFM system, select the stacker you need (for example, Stacker B).
4. Select one of the following checkboxes in the Set Registration Quality area of the window:
Improve Set Registration:
If sheets exiting the print engine have an excessive amount of upcurl preventing the BFM from pushing sheets from the lead
edge into registration position, select this checkbox. This selection enables and lowers the scuffer in the BFM, which applies
pressure to the center of a dual staple job set, minimizing the amount of pucker or buckle between the staples. It also helps
push the sheets to the registration gate. In addition to improving set registration, this feature helps to reduce jams.
Improve Initial Pages Registration Within Set:
Select this checkbox if you are experiencing jams and paper curl within sets. The system disables buffering between sets.
While registration of stock is improved, productivity will be impacted. The system skips a number of pitches until the compiler
is ready to accept new sheets.
NOTE: Registration is not optimized for tabs and oversized covers . This includes stapled and unstapled sets. The first 200 -
500 sheets from a cold start may exhibit this problem. Machines left in standby recover much more quickly.
Using the Variable Shaped Tray
If you are still experiencing curl in the stacked output and want to further improve stacking quality, you can install the Variable Shaped
Tray on the stacker tray. The Variable Shaped Tray is available through a customer kit for all BFMs and can be installed and removed
by the customer. It is designed to enhance the stacking of stock in the tray by improving sheet flatness. If you are experiencing early
unloads, jams, curling or poor stacking, use this feature for paper <140 gsm, only after trying the standard decurl adjustments. Keep in
mind that some papers will run best without the tray installed, especially if no curl exists. Do not use this feature for stock >140 gsm.
To install the Variable Shaped Tray:
1. Slowly pull out the Elevator Tray on the BFM.
2. Place the Variable Shaped Tray on the BFM Elevator Tray. It drops directly into the Elevator Tray when it is in the unload
position.
3. Carefully push the Elevator Tray back into the BFM being careful not to damage the actuator on the right side of the tray.
To remove the Variable Shaped Tray:
1. Slowly pull out the Elevator Tray on the BFM.
2. Unload the stacker, if necessary.
3. Lift the Variable Shaped Tray off the Elevator Tray.
4. Push the Elevator Tray back into the BFM.
Unloading stock from the Variable Shaped Tray:
1. Slowly pull out the Elevator Tray on the BFM being careful not to disturb the stack.
2. Only unload up to two (2) reams of stock at a time, being careful to maintain stack integrity
3. For the the last two reams slide your fingers under the staple cutouts on the right of the tray.
4. Slide your hands back to mid-stack, lift and remove the stock.
