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

| Tiket tersangkut akibat terjepit |
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. |
On frog-launching redemption games like Happy Frog, players smash physical target buttons to activate mechanical launchers or lifts that throw plastic frogs onto scoring lily pad targets.
When the machine displays Err 01, Err 02, Err 03, or Err 04 alongside a failure where the frog mechanism cannot rise or launch ("Katak tidak bisa naik"), the issue points directly to a failure in the solenoid actuation circuit, position detection sensors, or mechanical linkage assembly.

| Monster ball drop |
A frequent operational fault reported by field technicians is Error 08 (E-08 / E 08), which signals that a ball has become physically wedged or hung up in the upper ball release/gate channel, preventing it from dropping smoothly onto the playfield.
 |
| Error 8 : disebabkan karna adanya bola yg tersangkut di atas |
🔍 Understanding Error 08 Symptoms
When Error 08 occurs on a Monster Ball Drop cabinet:
Error Code Display: The digital score/credit LED display flashes E-08 or E 08, accompanied by an audible error chime.
Game Cycle Freeze: The machine halts normal game startup or mid-game plays because the upper ball release mechanism fails to confirm a successful ball drop within the CPU's programmed timeout window.
Visible Ball Jam: One or more balls remain trapped or tightly wedged under the upper mechanical retainer bar or gate release bracket.

| Perbaikan : angkat sedikit besi yg menahan bola tadi untuk memberikan ruang agar bola tidak tersangkut. |

[ Ball Gets Trapped Under Upper Retainer Bracket ] <=== ROOT CAUSE (Insufficient Clearance)
│

Drop Sensor Receives No Ball Signal -> CPU Timeout -> Triggers "E-08"
Primary Cause:
Tight Retainer Bar Clearance: The metal retainer bracket/bar positioned above the ball chute sits too low, pinching the ball against the track.
Ball Size Variance & Wear: Over time, replacement balls or thermal expansion/surface grime increase ball friction, causing them to catch against tight metal guards.
🛠️ Step-by-Step Adjustment & Repair Procedure
Resolving Error 08 requires a simple mechanical clearance adjustment rather than replacing electronic components.

Detailed Repair Steps:
Power Down & Access Upper Chute:
Turn off the main AC power switch and open the upper cabinet service hatch or remove the front protective acrylic panel.
Locate the Ball Jam:
Identify the trapped ball stuck beneath the upper release arm or metal retaining bracket.
Adjust Mechanical Retainer Clearance (Perbaikan Adjustment):
Loosen the mounting screws holding the upper metal ball retaining bar.
Slightly bend or elevate the metal bar upward (by 1–2 mm) to increase vertical clearance in the channel.
Objective: Provide just enough overhead clearance so the ball rolls freely through the gate without binding, while keeping it low enough to prevent secondary balls from jumping the track.
Manual Roll Test:
Pass a ball through the chute manually by hand to ensure smooth, unhindered gravity feeding through the drop sensor area.
Re-tighten & Test:
Firmly tighten the mounting screws and power on the cabinet.
Enter the Test Menu or play several test credits to verify that balls drop reliably without triggering E-08.
