Failure Symptoms
Error Code Displayed: The game board enters an error state (often showing
Er 03,Err-Tk, or similar ticket fault indicators depending on the mainboard model).Motor Runs Continuously: The ticket dispenser motor keeps spinning endlessly without pushing paper out, eventually triggering a timeout system halt.
Complete Silence: When points are scored, the ticket motor does not run at all, and no tickets are fed.
Jam & Tear: Tickets enter the mechanism but crumple, jam, or tear before exiting the payout notch.
Failure Analysis: Where Is the Problem Located?

| Tiket tersangkut akibat terjepit |
When tickets fail to pay out, the fault typically lies in one of four areas:
[Mainboard CPU Signal] ──> [Wiring Harness / Power supply] ──> [Dispenser Motor Mechanism] ──> [IR Ticket Notch Sensor]
Mechanical Jamming: Paper lint, foreign objects, or misaligned paper feed paths.
Optical Notch Sensor Failure: The dispenser's infrared sensor fails to count paper notches, so the CPU doesn't know tickets are exiting.
Motor Circuit Failure: The $12\text{V DC}$ drive motor or its control transistor is damaged.
Logic & Driver IC Issue: The mainboard PCB signal buffer (e.g., input/output logic ICs) is not transmitting the command.
Step-by-Step Diagnostic & Repair Process

Step 1: Physical & Mechanical Inspection
Check Ticket Stock: Ensure tickets are properly loaded, not folded incorrectly, and that the tension roll is not too tight.
Inspect the Roller Path: Open the ticket dispenser module (such as Deltronic Labs DL-1275 or similar standard mechanisms). Check rubber rollers for wear, hardening, or accumulated paper dust.
Clean Rollers: Wipe down drive rollers using 99% Isopropyl Alcohol (IPA) to restore grip.
Step 2: Testing the Optical Ticket Notch Sensor (IR Sensor)
Most arcade ticket dispensers use an infrared through-beam sensor to detect the small triangle notches between individual tickets.
Symptom of Dirty/Faulty IR Sensor: The motor dispenses tickets continuously without stopping until an error triggers, or it dispenses 1 ticket and immediately halts with an error.
How to Fix:
Blow out dust from the optical notch sensor channel using compressed air.
Use a cotton swab with IPA to clean the small optical lenses (transmitter and receiver) on the dispenser board.
Inspect the notch LED status on the dispenser board: the LED should flash rapidly as tickets pass through the beam gap. If the LED stays solid ON or OFF, replace the ticket sensor board assembly.
Step 3: Voltage & Wiring Verification
Measure power input at the ticket dispenser connector pins using a multimeter:
Power Pin: Should read $+12\text{V DC}$ (or $+5\text{V DC}$ depending on dispenser model).
Ground (GND): $0\text{V}$.
Measure the Enable/Trigger Line while triggering a payout test:
When activated, the control line from the mainboard should pull LOW or HIGH to signal the motor drive circuit.
If $+12\text{V}$ power is missing, check cabinet fuses or power supply connections.
Step 4: Board-Level Diagnostic (Mainboard Driver Repair)
If the ticket motor, wiring, and sensor are tested and functional on a bench setup, but the machine still won't trigger payout from the main cabinet:
Trace the Ticket Output Line: Trace the trigger trace from the ticket output header back to the mainboard drive transistor or ULN darlington array IC (e.g., ULN2003 / ULN2803) or buffer logic IC.
Check Buffer ICs: As seen with coin input faults, signal line drivers between CPU and peripheral ports can burn out from power fluctuations.
Replace Damaged Transistor/IC: Desolder and replace damaged drive transistors or ICs on the main board to restore output control to the dispenser.
Quick Reference Troubleshooting Summary
| Symptom | Primary Cause | Recommended Action |
| Motor runs constantly, no stop | Dirty/Defective IR Notch Sensor | Clean sensor channel with IPA or replace dispenser optical board. |
| Motor does not turn at all | Blown fuse, broken wire, or dead motor | Check $+12\text{V}$ supply line and measure motor coil continuity. |
| Tickets jam frequently | Worn rubber rollers or physical obstruction | Clean rubber wheels; replace dispenser roller assembly if hardened. |
| Error code shown, sensor verified working | Faulty driver on mainboard PCB | Trace PCB output line; replace buffer IC or drive transistor. |

berfungsi sebagai pengaman hubungan singkat/korselet serta mempunyai fungsi pengaman beban lebih,MCB otomatis akan memutuskan arus bila arus yang melewatinya melebihi batas nominal yang telah ditentukanpada MCB tersebut,
nominal arus MCB adalah 1A,2A,4A,6A,10A,16A,20A dan lain sebagainya.
Beberapa manfaat (fungsi MCB) adalah sebagai berikut :
1. Pengaman hubungan arus pendek
secara otomatis MCB akan trip bila terjadi korslet/ arus pendek
2. Mengamankan beban lebih
secara otomatis MCB akan trip bila over beban
3. Sebagai saklar utama

When a player hits a target or drops a ball into a scoring chute on Slam A Winner, the machine is expected to add points to the score display and payout physical tickets accordingly. However, a frequent issue encountered in field operations is when the ball successfully enters the scoring target, but no score is registered and no tickets are dispensed.

Fault Breakdown & Diagnostic Summary
Reported Fault: Score is not recorded on the display, and no tickets are dispensed when target holes are hit.
Root Cause: Defective, misaligned, or oxidized Needle Switch (Microswitch with Whisker Actuator).
[Ball Hits Target Lever] ──(Fails to Close Contact)──X──> [No Input Signal to PCB] ──> [No Score Registered / No Tickets Issued]
Why Does the Needle Switch Cause This Failure?
 |
| Sensor/ switch bagian tengah |
In Slam A Winner, needle switches (whisker-actuated switches) act as the physical trigger inside the score chutes and target channels. They feature both Normally Open (NO) and Normally Closed (NC) contact terminals.

| switch jarum NO-NC |
Physical Bending/Misalignment: Because balls drop directly onto the thin metal arm/needle, high usage causes the needle to bend over time. As a result, a falling ball no longer pushes the arm far enough to actuate the switch mechanism.
Contact Surface Oxidation/Pitting: Constant electrical arcing and ambient moisture lead to oxidation on the internal contacts. Even if the needle is pushed physically, the electrical circuit fails to bridge, keeping the signal floating.
Internal Spring Fatigue: The return spring inside the microswitch loses elasticity or breaks, leaving the contact stuck in between states.
Since the central control CPU never receives the pulse input from the COM $\rightarrow$ NO contact closure, it assumes no target was hit. Consequently, no points are added to the display, and no payout signal is triggered for the ticket dispenser.
Diagnostic & Repair Process
Step 1: Physical Inspection of the Needle Switch
Power down the machine and open the target scoring assembly panel.
Inspect the thin wire needle/lever of each scoring switch.
Verify that the needle sits directly in the path of the ball and moves freely without binding against the chute walls.
Manually drop a ball down the channel and observe if the needle depresses with a distinct, sharp "click."
Step 2: Electrical Testing with a Multimeter
Disconnect the wiring leads from the target switch's COM and NO terminals.
Set your multimeter to Continuity Test Mode or Resistance ($\Omega$) Mode.
Place one probe on the COM terminal and the other on the NO terminal.
Resting State: The meter should read Open Loop ($1$ or $\infty\ \Omega$) with no beep.
Manually Depress the Needle: Press the whisker arm fully.
Good Switch: Reads near $0\ \Omega$ with a continuous beep.
Faulty Switch: Reads high resistance ($>5\ \Omega$), fluctuating values, or no continuity beep at all.
Step 3: Repair & Replacement Steps
Adjust the Arm (If Misaligned): If the electrical continuity test passes when pressed manually, gently bend the wire needle to ensure the falling ball applies sufficient leverage.
Replace the Switch (If Contacts are Degraded):
Unbolt the faulty needle switch from its mounting bracket.
Install a new arcade-grade microswitch equipped with a whisker/needle lever.
Re-solder or attach the harness terminals correctly: signal wire to NO (Normally Open) and ground wire to COM (Common).
Test Game Play: Power on the unit, drop test balls into every scoring chute, and verify that the display increments score instantly and triggers ticket payout.
