d. Adjustment.
(1) Place an old print between the drum and the apron at the squeegee roller (fig. 3-14) with the
squeegee roller in the MATTE PRINTS position.
(2) Move the squeegee roller to the GLOSSY PRINTS position.
(3) Pull the print and note the amount and the evenness of the tension required to remove it. If
the print pulls easily, the spring tension is not great enough.
(4) Adjust the spring tension by tightening the hexagonal nuts on the anchor bolts attached to the
squeegee roller tension springs. Turn the hexagonal nut on each anchor bolt the same number of turns so that
the tension on both ends of the squeegee roller is equal. Shift the position of the two squeegee lever
assemblies (5) if the squeegee roller is worn and the hexagonal nuts have to be taken up more than a few
turns.
(5) The squeegee lever assemblies are slotted on the bottom for adjustment. Loosen the bolts
(not shown) in each squeegee lever assembly base and shift them as required. Tighten the bolts and recheck
the pressure on the test print (3). Be sure that the tension on the test print is equal at both ends of the
squeegee roller.

Replacing the drive roller assembly on the EL-5(1).
a. Removal.
(1) Remove the screws (4, fig. 3-13), the lockwashers (5), and the bearing retainer (6).
(2) Hold the snub roller (8) and slide the drive roller assembly (7) out through the opening in the
frame left by the removal of the bearing retainer (6).
(3) Remove the snub roller.
b. Repair.
(1) Refinishing. If the rubber surface of the drive roller assembly is hardened, refinish it with
fine sandpaper. Be sure the finished surface is smooth and even. If more than 1/8-inch of rubber is removed,
or the drive roller does not provide the proper apron tension, replace the drive roller or the drive tube (3, fig.
3-18).
