Roller Alignment Instructions
Prior to shipment, the JM63 Fuzion XD is carefully inspected. Inspection includes making sure the roller alignment is
calibrated and tested for paper travel at 20-60% pressure. Paper deviation of less than 0.12” (3mm) for 20’ (6m) of
travel (maximum standard) is likely to increase above 60% pressure due to roller de
fl
ection. For best results with most
applications, processing at 40% pressure is recommended. If paper travel or excessive wrinkling occurs, perform the
following procedure for roller alignment.
Required Tools: (2) 10mm open end wrenches, (1) set of metric Allen wrenches
1. Ensure the machine is level front to back and side to side, with casters locked to prevent movement.
2. Disconnect the machine from the power supply.
3. Remove both end case panels and set them aside.
4. Raise the top roller slightly until there is a visible gap between it and the bottom roller. Slowly lower the top
roller until part of it touches the bottom roller. If the gap between the top and bottom rollers is uneven, an
adjustment must be made. Proceed to Step 5. If not, test for paper travel at 20% and 40% pressure before
proceeding. A small visual difference in the gap may not necessarily cause poor paper travel or wrinkling,
and therefore, may not require roller adjustment.
5. Raise the top roller so that it is not touching the bottom roller. Check the gap between the upper and lower
bearing blocks (Figure A). If there is no gap or the gap is uneven, adjust the two leveling bolts next to the
spring washer stacks to create a 0.08” (2mm) separation between the upper and lower bearing blocks.
Adjust the bolts to ensure the two bearing blocks are parallel with each other.
NOTE
:
Because the sensor is located in the left end case, any adjustment made to the bearing block on that side can affect
height and pressure readings. Therefore, it is recommended that any adjustment be made to the bearing block in the
right end case
fi
rst.
There must be an even gap
between the upper and lower
bearing blocks on each side
of the machine.
