S4 Scaner error

[Tubylec1982]

Hello. I replaced the rubber wheels on the 135/240 carrier. After reassembly, I get error 1409. Set the film path in the mask. Id doesn't matter if i set track for  135 or 240 .I checked all the tape connectors, and everything looks fine.What else i should check ?

Lane selection circuit is simple. Lane limit switches have connect J/P17 contact 12, or J/P17 contact 13 to ground ( when selected 135, or 240 lane ) . Intermediate connectors between J/P17  and lane switches are J/P1008 , J/P1009 , J/P1032 and J/P1033 . Check do you have 0V on J/P17 contacts when lane selection switch is pressed.

Is there a wiring diagram available somewhere?

I'll try to check it tomorrow or on the weekend

135/240AFC-II circuit diagram is on minilab service manuals ( for QSS32 and later models ) .How everything connected can see on my post above.

I found a cracked one Flexible Flat Ribbon Cable from sensor PCB to driver pcb2 i think so

AWM 20624 80C 60V  is not a model. Here just cable UL-AWM specifications ( flexibility, temperature, voltage, etc ) . VW-1 is flammability rating.  e41447-k is cable style.
Here is 1 mm pitch 14 pin flat flexible cable ( FFC ) . If to buy cable from Noritsu then part number is W407026-01 . Also can buy it from cable makers.

After replacing the 36-pin connector, the film position error is gone. But there are others: charging sensor error, perforation sensor error, and ready sensor error. There's also an error - the sensor sensitivity hasn't been set. But it can't be set because errors for all three sensors are popping up.

Load in your backup data, that should clear the Sensor calibration has not been completed yet error.

Enter the service mode, on the film carrier adjustment screen, enter 255 for the Perforation and Ready sensor and LED values, register, now go into input check and see what the status is for the Perforation and Ready sensors. If they are still showing dark, there will be some hardware issue with film carrier.

The new tape was damaged, I put on a second one and there are no errors except the previous one about setting the correct track for the film (error 1409)

To this cable connected APS spool motor driver, lane selection switches ( 135, 240 ) and nothing else. This cable can't effect how work sensors. To sensors connected two other cables.

Cable is 75 cm length , 1 mm pitch , 14 pins, B type ( contacts are opened on different sides - reverse direction  ) . It is easy to find similar cable ( 80 cm , or 800 mm  length ) . On film carrier space is enough to fit 80 cm cable instead of 75 cm. Cable is cheap. Two pieces of 14 pin, 800 mm length , reverse direction, 1.00mm pitch cables on online shops cost about 6 EUR.

Not so easy to repair 135/240AFC-II . I had to make self made equipment to have possibility to test and calibrate sensors when AFC is diassembled. Then can repair film carrier without scanner.
