    Well as no one has replied to you yet i will try
    The sensors on the sprint 228 are set at 295 degres,Check to make sure the eye is turned on and selected,put a sheet on the board and see if the lights are lit or go out,use the paper to determine if the lights go on or off when a sheet is present as i cannot remember if the lights go on or off. If the light goes on when a sheet is present then turn the sensor till the light goes offf then just on and turn a small amount more just so you are not on the border. The sensors should be under the feedboard and labeled RF LF with an in and out for inside and outside eyes. If you adjust the overshoot as well make sure that a piece of paper is over the eye as it is set back from the headstops
    This procedure works for the press with the smooth paint job not sure if the older 228 with the orange peel finish is the same
    Good Luck

    I asked about the eyecom myself earlier this month and got this info> maybe itll help you.....>


    "1) Rotate the press so that the sensor paddles are raised.

    2) Clean the projection lenses and sensors under the paddles with alcohol or a dampened cloth or Q-Tip. Wipe the surfaces with a clean dry cloth or Q-Tip.

    3) Rotate the press to approximately 295 degrees.

    4) While holding down the “ADJUST” button

    A) Turn the “P” control to the point at which the lamp is just off.
    B) Turn the “D” control to the point at which the lamp is just on.
    C) Turn the “LF” control to the point at which the lamp is just off.
    D) Turn the “RF” control to the point at which the lamp is just off.

    5) Release the “ADJUST” button. The lamps should change to their opposite states. When the “ADJUST” button is pressed again, the lamps should appear as in step # 4.

    Adjust Button Depressed . . . . . . Adjust Button Released

    P --- OFF. . . . . . . . . . . . . . . . . . . P --- ON

    D --- ON . . . . . . . . . . . . . . . . . . . D --- OFF

    LF --- OFF. . . . . . . . . . . . . . . . . . LF --- ON

    RF --- OFF. . . . . . . . . . . . . . . . . . LF --- ON

    If any of the lamps will not set as shown above, try adjusting the paddle sensors so that they are directly over the projection lamps. The center paddle is the double sheet detector and should be no more that 2.5 mm. above the projector lens. If the lens is cloudy it can be removed temporarily until a new lens is installed. New lenses must be carefully trimmed to fit tightly into the cutout. Super glue can be used but be careful not to cloud the lens. Order extra lenses as they can easily be broken during fitting.

    If you suspect a faulty sensor, connect a voltmeter to the two outer pins of the sensor plug. The meter should indicate just under 0.5 volt when the sensor is illuminated. The double sheet sensor paddle may appear similar to the LF and RF paddles but should have a larger square photocell when viewed from the bottom.

    If the settings will not hold, tap the faceplate of the Eyekom. If the LED lamps flicker, the Eyekom should be repaired of replaced . If any of the LED lamps flicker while turning the dials, this also indicates that the Eyekom should be repaired or replaced."
