Type 1 SELECTIVE

Issue number 1

PURPOSE:

The TILT MOTOR SHAFT is replaced with a new shaft which provides an earlier actuation of

MICROSWITCH MS 14 to prevent the TILT MOTOR over-running. If the motor over-runs, film jams can

result in the SUPPLY MAGAZINE or the MULTIPLE FILM LOAD DETECTOR area.

NOTE - Modification M17 added a potentiometer to control the speed of the TILT MOTOR, and in most

cases this will provide all the control needed. However some TILT MOTORS cannot be satisfactorily

adjusted for speed by modification M17. If is possible that the speed has to be set so slow to prevent

over-running, that the TILT MOTOR occasionally stalls.

IMPORTANT: Only qualified service personnel should install this modification!

SERIAL NUMBERS: 1162 - 1269

SCREW 1

Switch off the MINILOADER, and remove the TOP COVER and the left (looking from the front) SIDE PANEL.

Disconnect the TILT PUSH ROD by removing the M4 SCREW (SCREW 1 in FIGURE 1) on the TILT LINKAGE.

Disconnect the CASSETTE SUCKER BAR PUSH ROD by removing the SCREW (SCREW 2 in FIGURE 1) from the LEVER. CAUTION - support the SUCKER BAR as you remove the SCREW, and gently lower the SUCKER BAR to the CASSETTE CONVEYOR BELT as it becomes loose. Do not attempt to disconnect the CASSETTE SUCKER BAR PUSH ROD by unscrewing the PUSH ROD, as you will destroy the adjustment.

LIGHT SEAL

Carefully peel back the LIGHT SEAL to gain access to the SCREWS that secure the TILT MOTOR ASSEMBLY and remove them.

By rotating the complete assembly by 90 degrees it is now possible to withdraw the TILT MOTOR ASSEMBLY from the MINILOADER. The MICROSWITCH WIRES are still connected to the WIRING HARNESS so you must keep the assembly alongside the MINILOADER.

Remove the SCREW (1 in FIGURE 2) that retains the two MICROSWITCHES, and then rotate the MICROSWITCHES away from the CAM ASSEMBLY.

SCREW 1

Remove the three SCREWS that secure the TILT MOTOR to the MOUNTING BRACKET. Hold the CAM FOLLOWERS away from the CAMS and withdraw the TILT MOTOR. The hole in the MOUNTING BRACKET is profiled to allow the withdrawal.

MA 3211-31 August 1992

Change the existing SHAFT for the new SHAFT, reusing the GRUB SCREW. The new SHAFT has the FLAT for the MICROSWITCH operating CAM advanced by 15 degrees compared to the old SHAFT. This ensures the MICROSWITCHES are operated earlier. Reassemble the TILT MOTOR on the MOUNTING BRACKET.

Replace the MICROSWITCH MOUNTING SCREW, and adjust the MICROSWITCHES so the SWITCHES are not bottomed as the CAMS rotate.

Refit the TILT MOTOR ASSEMBLY in the MINILOADER and refit the LIGHT SEAL.

Refit the CASSETTE SUCKER BAR PUSH ROD onto the LEVER.

Refit the TILT PUSH ROD.

Load some TEST FILM into the SUPPLY MAGAZINE and run some cycles to check the operation of the TILT. If necessary adjust the speed of the TILT MOTOR by means of the POTENTIOMETER P601 on PCB 106A/B. It should be possible to run the TILT MOTOR faster now that the modification has been carried out.

Circle M31 on the MODIFICATION LABEL and refit the PANELS.

Type 1 Required

PURPOSE:

To change the speed of the cam motor to stop cam system malfunctions, to prevent damage to the

cam motor relays, and lengthen the life of the cam motor. Film handling is also improved.

This modification will also prevent spurious blowing of the cam motor fuse.

IMPORTANT: Only qualified service personnel should install this modification!

MODIFICATION INSTRUCTIONS

Switch off the power to the MINILOADER and remove the TOP COVER and the right hand (from the

front) SIDE PANEL.

On the CAM MOTOR, identify the CONNECTOR STRIP. Un-solder the WHITE WIRE marked "C" and the CAPACITOR from the CONNECTION that the RED MOTOR WIRE is connected to, and resolder the WHITE WIRE and the CAPACITOR to the CONNECTION that the GREEN MOTOR WIRE is connected to. See FIGURES 1 & 2.

FIGURE 1. Before the modification.

FIGURE 2. After the modification.

Replace the right hand SIDE PANEL, and turn the power to the MINILOADER on.

Using the SWITCHES on PCB 303 enter the PROGRAMMING MODE. (SWITCH 1 ON) Check that

the DATE & TIME are still correct, reset if necessary. Check the SERIAL NUMBER is still correct, change if necessary. Select the required LANGUAGE. Note that PARAMETER P3, "MULTIPLE FILM DETECTION PAUSE" can now be reduced to 0.5 Seconds (previously 1.0 Second) because as the CAM MOTOR is now moving more slowly, less time is required for the FILM to stabilise.

On most MINILOADERS, the cycle time after doing this modification does not change. This is

because although the CAM MOTOR is running more slowly, the time for HOME POSITION to be reached at the end of the cycle is much reduced as, due to the slower speed, the program is able to stop the CAM MOTOR in HOME POSITION first time, and does not need to "hunt" for HOME POSITION. However, on PROCESSOR INTERFACE MINILOADERS, it is necessary to check that PARAMETER P4 "GAP BETWEEN FILMS" is still correctly set. The correct way to do this is to check the gap between films leaving the PROCESSOR in SERIAL MODE, and alter PARAMETER P4 if necessary.

Circle MOD M01 on the MODIFICATION LABEL, re-assemble the MINILOADER and test .

PURPOSE:

On some MINILOADERS it is not possible to adjust the MAGAZINE SUCKER BAR to prevent FILMS

being pulled back out of the CASSETTE by the SUCKERS as the SUCKER BAR returns from the

CASSETTE.

This modification replaces the old SUCKER BAR with a bar of a new shape.

The new SUCKER BAR can be identified by a white spot on the mounting.

MODIFICATION INSTRUCTIONS

1. Remove the MINILOADER COVER and the non-drive SIDE PANEL. Remove the FILM MAGAZINE(S). Unload the SUPPLY MAGAZINE and place some TEST FILMS in it. Replace the SUPPLY MAGAZINE in the MINILOADER.

2. Remove the MAGAZINE SUCKER BAR from the MINILOADER, retain the SUCKERS and discard the old BAR. IMPORTANT - Do not touch the surface of the SUCKER with your hand,

use a GLOVE or a CLEAN CLOTH to handle the SUCKERS.

3. Fit the SUCKERS on the new SUCKER BAR IMPORTANT - Make sure the SUCKER with the “O” RING inside is fitted to the mounting end of the SUCKER BAR.. This ensures correct

separation of FILMS when the vacuum is applied to the SUCKERS. See Figure 1.

F igure 1.

4. Fit the new SUCKER BAR to the MINILOADER taking care not to damage the "O" RING SEAL inside the SUCKER BAR MOUNTING. Using the JOG SWITCH (on PCB 106) jog the machine until the MAGAZINE SUCKER BAR is just above the TEST FILM in the SUPPLY MAGAZINE. See Figure 2. Loosen the two GRUB SCREWS on the SUCKER BAR and adjust the angle of the BAR, so the SUCKERS are parallel with the FILM. If necessary alter the individual SUCKERS, so both SUCKERS are parallel..

5. Jog the machine further through the cycle and make sure that the SUCKER BAR does not touch the CASSETTE SCREEN as the SUCKER BAR enters and leaves the CASSETTE.

F igure 2.

There must be clearance between the sucker

bar and the cassette screen here.

Suckers parallel to the films here

MB 3211-32 June 1992

There should be a gap of 1 mm between the sucker and the film when the vacuum is released.

6. Fit the STEP BY STEP SWITCH to the MINILOADER (see the SERVICE MANUAL for instructions if necessary). Run some cycles and check that the FILMS enter the CASSETTE correctly.

The FILM should be “tucked into” the HINGE of the CASSETTE without catching the BASE of the CASSETTE or the SCREEN. The FILM must not be pulled back out of the CASSETTE when the SUCKER BAR returns. There should be a gap of a least one millimetre between the FILM and the SUCKER when the vacuum is released.

If necessary adjust the angle of the CAM FOLLOWER (1), the height and/or angle of the STATIC CAM (2) or the height of the STOP (3). It may also be necessary to adjust one of the PUSH RODS which drive the SUCKER BAR.

7. When the FILM is entering the CASSETTE correctly, check that the SUCKER BAR presses against the STOP (3) with a force of 0.5 to 1 kg. Adjust the PUSHROD if required.

8. Circle M 32 on the MODIFICATION LABEL, replace the SIDE PANEL and the LID of the MINILOADER. Reload the MAGAZINE(S) and if possible process some film to check for ARTIFACTS.
