Page 5: Introduction
INTRODUCTION PREFACE The KF-250 is a precision folding machine. With its intuitive touchscreen design, it can perform 6 different types of automated setup folds of pre-creased paper. It has a manual feature that allows for the fold to be placed virtually anywhere on the sheet. When properly setup and using pre-creased sheets, the knife blade folding mechanism will prevent the cracking of digitally printed material when folded. -

Page 10: Bi-Pass Tray Installation
BI-PASS TRAY INSTALLATION As shown below, there are hooks that hold the bi-pass tray into position. If the magnetic paper stops have already been placed, you should remove them for easier installation of the tray. First, angle upward and insert the upper hooks into the upper slots and then rotate downward to place the lower hooks into the lower slots. -
Page 11: Machine Operation
MACHINE OPERATION There are two power switches on the KF-250 located on the lower portion of the operator side cover. One is the main power (top) and the pump (lower). Everything else is controlled by the Touch Screen. All paper run through the KF-250 folding machine must be creased. -

TOUCH SCREEN CONTROLLER THE TOUCH SCREEN CONSISTS OF FOUR SECTIONS: 1. Count Logo and Service Access 2. Auto Setup 3. Manual Setup 4. Repeat Last Job TOUCH SCREEN OPERATION When the machine is turned on, the display may take up to 7 seconds for the home screen to display. -
Page 13: Auto Setup Screen
AUTO SETUP SCREEN From the home screen press the Auto Setup button. The select fold screen appears. Press the desired image to select that fold. Select the fold you want by pressing the image. PAPER THICKNESS Select the thickness of paper to be folded. This is important as thinner stocks will fold differently than thicker stocks. -
Page 14: Knob Settings / Gap Adjustment
KNOB SETTINGS / GAP ADJUSTMENT This adjustment is very important and affects the operation of the machine dramatically. The knobs are positioned from left to right. Knob 1 is on the left and knob 2 is on the right. Knob 1 controls gap 1 and knob 2 controls gap 2. -
Page 15: Measure Sheet
Once measured press accept to go to the run screen. RUN SCREEN On the Run Screen there is a counter that will count how many sheets are run through the machine. It can be reset by pressing the counter reset. When the run button is not selected you can jog the machine forward and backward using the jog arrows. -
Page 16: Micro Adjusting The Fold Position
MICRO ADJUSTING THE FOLD POSITION It is very important to understand the relationship of the fold offset versus the crease offset. When folding a creased stock, the nature of the creased paper when folded is to follow the crease. If possible, adjust the crease before micro adjusting the fold. If you wish to move the position of the fold relative to the lead edge you would need to adjust the position of the crease and not necessarily the position of the fold. -
Page 17: Transport Operation
TRANSPORT OPERATION The Run Button will start the knife home function. Once the blades are in position the transport will start. This is about a 2 second delay and is normal. Press it again to stop the transport. Each Mode has a timeout feature to preserve the life of the machine. ... -

Page 23: Adjusting The Feed Rail
ADJUSTING THE FEED RAIL The fixed feed rail on your KF-250 is factory set and should not be adjusted. If necessary, it is possible to have slight adjustment to the rail by using the button head screws on the bottom of the feed rail. -
Page 24: Setting The Automatic Feeder
SETTING THE AUTOMATIC FEEDER For efficient Auto-feeding, the setting of the Paper Caliper is very important. Make sure the pump is off while adjusting the caliper. Use a piece of the stock to be run as a “feeler gauge”. Place one sheet under the caliper and place another sheet on top of that sheet. Now move it back and forth under the caliper while adjusting the caliper down (counterclockwise to lower, clockwise to raise) until the second sheet is not able to go under the caliper. -
Page 25: Feeding Notes
The lighter the stock, the lighter the ball combo needs to be. DELIVERY TABLE The delivery table for the KF-250 is a motorized delivery that has a variable speed knob that is used to adjust the speed. It also has a smart sensor that ensures the paper only travels a short distance to ensure continued shingling. -
Page 26: Checking The Sensors
CHECKING THE SENSORS 1. Turn machine power on and allow screen to turn on 2. There should be 2 lights on the sensor; a green indicating power is getting to the sensor and orange that is the reflecting signal. If both lights are not on, there is a problem and must be fixed before you are able to run. -
Page 27: Trouble Shooting
TROUBLE SHOOTING POWER DOES NOT TURN ON 1. Check circuit breaker in electrical cabinet. 2. Make sure the power switch is being controlled and not the pump switch. 3. Check outlet for power. TRANSPORT “LOCKS UP” AFTER OR WHILE FOLDING 1.
