I. DESCRIPTION

GENERAL:

ProPack is the latest model in the family of Reporter and EE100 cameras. It is shown in Figure1-1 in the closed position and in Figure 1-2, in the picture-taking position. As can be seen in theillustrations, the ProPack looks much like the earlier models. In fact, it shares many commonfeatures with the Reporter and the EE100

.

6 ProPack Camera

This section of the Repair Manual is divided into two major parts: “Similarities to Reporter/EE100” and “New Features.” Although the similarities are briefly discussed here, you shouldreread the Reporter and EE100 manuals to gain an in-depth knowledge of these areas which arecommon among the three camera models.

Among the new features in the ProPack are an interface capability with a dedicated electronicstrobe called ProFlash, a modified CB103 camera back, and an integral digital electronic timer.Using 3000 speed film and the new electronic strobe, the camera can take unusually distant shotsat night. With 3000 speed film and the film selector set to 80, well-exposed pictures can bemade of subjects within a subject range of 50 to 75 feet (15.2 to 22.9 meters). These featureswill be discussed in detail later.

SIMILARITIES TO REPORTER/EE100:

Film

Nine types of pack film may be used in the ProPack:

Erecting System

The erecting system works identically to the systems in the Reporter and EE100 cameras. Toopen the ProPack to the picture-taking configuration, the release button on the top of the cover ispressed. This unlocks the erecting system and allows the cover to drop down. The shutterbellows extend forward and latch into the picture-taking position. (see Figure 1-2) As theshutter moves into the latched position, the flash diffuser shield swings out.

To close the camera, the release button is again pressed to unlock the erecting system from thepicture-taking configuration. Then, the front cover is pushed toward the body until it latchesclosed. Note that as the camera is being closed, the flash diffuser swings back into position infront of the shutter housing.

Focusing

As with the earlier cameras, focusing is done by first estimating the camera-to-subject distance.Then, the lens bezel is turned until the number corresponding to the estimated distance is setunder the colored pointer on the shutter face. Camera ranges for specific films and lightingconditions are presented in Table 1-3 on page 14.

Framing

To frame the subject, look through the fixed viewfinder on top of the camera. As seen in Figure1-3, there are two sets of framing lines (Albada lines). When using T100 or T600 series film,the outside lines (rectangular shape) are used to frame the subject. When using T80 series, theinside lines (square shape) are used to frame the subject. The Albada lines indicate that portionof the subject area that will appear in the finished photograph.

FIGURE 1-3 FRAMING THE SUBJECT

Page 8: Polaroid ProPack Repair Manual

Taking The Picture

The shutter release in the ProPack works the same as the shutter release in Reporter and EE100cameras. When the shutter button is pressed, it closes switch S1, initiating the electrical se-quencing. Mechanically, the shutter release pushes down on the capping blade arm and thecapping blade swings upward, out of the optical path. At the end of its movement, the cappingblade closes the flash switch (S4), releases the opening blade, and the film is exposed. Whenenough light is measured by the photocell, the closing blade is released by the magnet and theexposure is complete. As the shutter button is released, the three shutter blades return to theiroriginal position.

Electronic Shutter

As mentioned before, the ProPack has an electronic shutter run by two 1.5 volt alkaline batteries.The shutter operates much as the shutter in the Reporter and EE100. Shutter blade operation andflashcube indexing is exactly as before.

Electronically, the ProPack has been modified to accept an electronic strobe called the ProFlash.(See New Features portion of this section.)

Other Similar Features

Other features of the ProPack which are similar to the Reporter and EE100 are:

— a lighten/darken control on the shutter trims exposures from- 0.8 stop to + 1.0 stop.

— a heavy duty neck strap allows the camera to be comfortably carried.

— a tripod socket in the bottom of the camera body which accepts most tripods.

— a threaded cable release socket on top of the shutter housing permits the use of aremote shutter button.

— a ring handle on the door which is used to hold the camera when film is beingpulled through the spread system. The ring handle folds away into a recess in thedoor when it is not being used.

NEW FEATURES:

An inspection of the ProPack shows that there are some subtle differences and some strikingdifferences between this camera and the earlier Reporter/EE100.

Electronic Flash Capability

The most important difference between the ProPack and the earlier cameras is the ability of heProPack to interface with an electronic strobe called ProFlash. (The ProFlash is covered in a

Page 9: Polaroid ProPack Repair Manual

9 ProPack Camera

separate Repair Manual.) ProFlash extends the range at which the ProPack camera can makeflash exposures. The ranges for the various modes are detailed in “Film/Camera ExposureCharacteristics.”

Figure 1-4 shows the ProFlash installed on the ProPack camera. The flash is mechanicallyconnected to the camera via a bracket secured to the tripod socket.

FIGURE 1-4 PROFLASH INSTALLED ON CAMERA

FIGURE 1-5 PROPACK CAMERA HOT SHOE CONNECTOR

A close-up of the tripod socket area on the camera (Figure 1-5) reveals a hot shoe connector.This hot shoe mates with a corresponding five pin connector contained in the ProFlash bracket.An electrical cable contained runs through the bracket to the body of the flash carrying thesignals needed to fire the ProFlash in synchronization with the shutter opening. A five wire

Page 10: Polaroid ProPack Repair Manual

10 ProPack Camera

cable from the hot shoe to the base of the shutter housing (Figure 1-6) completes the connectionbetween the camera electronics and the flash electronics.

FIGURE 1-6 FLASH TO SHUTTER FIVE WIRE CABLE

CB103 Camera Back

The ProPack employs a modified CB103 camera back. This camera back has a built-in plasticlatch instead of the metal bail latch used in the Reporter and the EE100. The back surface of thedoor has two recesses; one is for the ring handle and the other is for a new electronic develop-ment timer.

As can be seen in Figure 1-7, the pack spring arrangement in the CB-103 differs from the packspring arrangement in earlier cameras. In the CB-103, there are actually two different springsarranged along the same plane in which the film is pulled from the camera.

FIGURE 1-7 MODIFIED CB103 CAMERA BACK

Page 11: Polaroid ProPack Repair Manual

11 ProPack Camera

FIGURE 1-8 DIGITAL ELECTRONIC TIMER

Electronic Timer

The electronic digital timer (Figure 1-8) can measure time periods up to 19 minutes, 59 seconds.The timer has a self-adhesive back which holds it to the recessed surface in the door. It is pow-ered by two replaceable type AG-10 batteries.

To set the timer...

Hold the SET button in. The digital display will increase by one second, pause, then increase ata rapid rate. When the desired time is near, release the SET button. Then, increase the time onesecond at a time by alternately pressing and releasing the SET button until you reach the desiredsetting.

To start the timer...

Press the START button. The timer will beep once to indicate the countdown has started. Then,the timer digital display will sequence backwards one second at a time until the timing period isover. At the end of the time-out, the timer will beep twice, pause and then beep twice again.

At the end of the sequence, the timer will automatically reset to the pre-selected timeout period.

To reset the timer to 0...or, to reset a blank screen...

Simply press the start and set buttons simultaneously. The digital display will very briefly read“18:88) and then will step back to “0:00.”

Page 12: Polaroid ProPack Repair Manual

Film Selector ( Refer to Figure 1-9)

The ProPack has a film selector on top of the shutter housing which is used to establish theproper lens aperture for the type of film being used. There are three settings:

o “80” for color film;o “3000” for black & white film;o “3000ER” for black & white film in low light

(In the Reporter and EE100, the color setting is labeled “75”).

Although all of the camera models have three settings, the apertures which result differ. Thefollowing table shows the apertures resulting from the various film selector settings:

TABLE 1-2FILM SELECTOR APERTURES

Film Reporter/Selector EE100 ProPackSetting Aperture Aperture

75/80 f 9.2 f 9.23000 f 60 f 60

3000 ER f 9.2 f 18

You can see that the 3000ER setting in ProPack results in an f 18 aperture versus the f 9.2 aper-ture in Reporter and EE100. The f 18 aperture improves the sharpness of pictures taken in thismode.

FIGURE 1-9 FILM SELECTOR SETTINGS

Page 13: Polaroid ProPack Repair Manual

13 ProPack Camera

HOT SHOE PIN FUNCTIONS(Refer to Figure 1-10)

As mentioned previously, the hot shoe connection on the camera has five pins which mate withthe five pin connector in the ProFlash. The function of each of the five pins is as follows:

Pin 1 connects camera ground to the strobe ground.

Pin 2 carries information which informs the strobe exposure circuit of the setting of the camerafilm selector. That is;

Setting Pin 2 Voltage

80, 3000 +0.67 V (nominal)3000ER 0.00 V

Pin 3 connects the + side of C2 (the camera integration capacitator) to the ON pole of the strobeON/OFF switch. When the strobe is ON, pin 3 works in conjunction with pin 4.

Pin 4 connects the + side of C3 to the common pole of the strobe ON/OFF switch. With thestrobe ON, C3 is connected in parallel with C2 (3000ER) and with C1 (80 or 3000).

In the strobe mode, the network of capacitors C1, C2, C3, and resistor R6 provides a shutterspeed of about 1/125th of a second. When the strobe is turned OFF, pin 4 inhibits the flash fromfiring and the camera operates in the ambient mode.

Pin 5 connects shutter switch S4 (through resistor R11) to the strobe trigger circuit. Therefore,when S4 is closed by the shutter capping blade, a voltage is transmitted to the strobe. If thestrobe is ON, it will fire. Typical transmitted voltages area:

STROBE ON/OFF SWITCH ON - + 0.5VSTROBE ON/OFF SWITCH OFF - + 0.1V

D. CAMERA/ELECTRONIC FLASH GRAYWALL TEST

NOTE:This test pre-supposes that the wiring between camera and flash is OK. If you havepersistent problems with graywall testing, first check the flash cable connection at the shutter.Be certain that the cable is properly mated between the flash contacts at the tripod and theshutter connector.

The camera/electronic flash graywall test is done on the Model B or Model B-600 Tester (youmay turn the Light Source OFF) with the electronic flash installed on the camera and the cameramounted on the traditional camera horn.

The purpose of this test is twofold:

Page 20: Polaroid ProPack Repair Manual

20 ProPack Camera

1) to determine if the electronic flash is working properly and,

2) to determine if the camera electronics are properly “reading” the output of theelectronic flash. If you cannot obtain the specified readings, replace the elec-tronic flash with a known good flash and retest. If the readings are still notwithin specification, replace the camera baseblock.

Setup

1. Set the tester as follows:

Test Selector Switch to 75 EXPTest Mode Switch to EXPOSURE

2. Open and erect the camera and install the electronic flash. Place the camera on thetraditional horn.

3. Set the camera as follows:

E. FLASH SOCKET CHECK AND ADJUSTMENT

1. Referring to Figure 2-4, examine the flash contacts:

a. If the contacts are broken, replace the baseblock.b. If the contacts are too low to make good contact with the flashcube pins,

carefully lift the contacts with tweezers. Lift the contacts as high as theywill go within the plastic housing.

2. Examine the flash socket holder. If the holder cover is loose or otherwise dam-aged, replace it. Use an approved commercial glue to hold the parts together. Ifflash socket holder parts are not available, you must replace the entire baseblock.

FIGURE 2-4 FLASH SOCKET EXAMINATION

F. SHUTTER VISUAL INSPECTION

1. Remove the baseblock from the camera. (Refer to Disassembly section.)

2. Visually examine the baseblock, looking for broken/missing parts. Replace anydefective/missing parts as necessary. Discard the baseblock, if necessary.

3. Actuate the shutter by pressing on the capping blade extension (point A in Figure2-5). The blades should move freely. Look for any mechanical binds caused bybroken or otherwise defective parts.

4. Check the position of the hooked end of the extension spring relative to switch S2(just under the end of the spring). The end of the extension spring must not touchswitch S2.

5. Be sure the keeper on the closing blade mates properly with the magnet. Tocheck this, disconnect the extension spring from its post and push the blades backso the keeper touches the magnet. The keeper must be within .002 to .030 inch(.050 to 7.62 mm) of the poles of the magnet. Adjust the position of the magnetas necessary.

Page 23: Polaroid ProPack Repair Manual

23 ProPack Camera

6. While observing switch S3, (Figure 2-6) insert and withdraw a flashcube. Themovable contact of the switch should make firm contact with the clips on thecircuit board. If it doesn’t, very carefully bend the movable contact so it makesproper contact with each clip on the board as it moves from one position to theother.

FIGURE 2-5 BASEBLACK INNER COMPONENTS

FIGURE 2-6 CHECKING FLASH SWITCH S3

Page 24: Polaroid ProPack Repair Manual

24 ProPack Camera

7. Examine flash switch S4. (Refer again to Figure 2-5). The switch contactsshould close only when actuated by the edge of the capping blade. At all othertimes, the contacts should be separated by about 1/32 inch (.07938cm). Also,check that the contact is not so severely bent that the capping blade will pass overit without actuating the switch. Carefully, bend the switch contacts to satisfythese requirements.

G. TIMING SWITCH (S2) ADJUSTMENT

The adjustment of this switch is critical. The switch must open immediately upon actuation ofthe opening blade to insure proper shutter timing for the entire exposure. Additionally, after theexposure, the switch must close positively to provide a path to completely discharge the timingcapacitator. Adjust the switch as follows:

1. Set a VOM to the R X 1 scale.

2. Place one of the VOM probes across both contacts of S1 (Figure 2-5).

3. Place the other probe on the stationary contact of S2. The meter should indicatecontinuity.

4. Slowly press point A on the capping blade until all of the slack is removed fromthe three blade assembly. The meter should still indicate continuity.

5. Turn the adjusting screw clockwise until the switch opens (no continuity).

6. Very slowly turn the adjusting screw counterclockwise and stop the instant themeter again indicates continuity.

7. Note the position of the screw-head, and then turn the screw exactly three fullturns counterclockwise.
