Tension Roller - Eiki ESL SERIES Service Manual

a. The tension roller (5) applies constant but gentle tension to stabilize the film over the
sound drum. The amount of tension is determined by tension spring (11 ).
b. In the "STOP" and "REWIND" position, the tension roller is at the top (See Fig.#84)
allowing the film to clear the sound drum.
In the "MIC" or "FORWARD" position, the roller swings down as it is released by
the main interlocking bracket. (See Fig.#85)
c. To check the roller tension, load the film and turn the function control to "MIC". The
tension roller should ride on the film with gentle tension. A slight push on the roller
should allow it to travel downward slightly. In "REWIND" the roller is raised up by the
interlocking bracket to clear the film path.
d. Adjustment: To adjust the tension roller's position, remove the control pannel and turn
function switch to "MIC" to expose the nut (4mm) from behind the interlocking
bracket. (See Fig. #89)
Fig. #89
Unhook the tension spring and using a 7mm nut driver, loosen the 4mm nut slightly
and return the function switch to "STOP".
(1) Bring the tension roller close to the No. 2 sprocket shoe roller keeping approxi-
mately 0.5mm gap.
(2) Turn the rotary switch to "MIC" holding the tension roller in the position.
(3) Tighten the 4mm nut.
(4) Hook up the tension spring.
(5) Make sure the tension roller position is correct at "STOP" "MIC" "REWIND".
