1. Top Metal Ticket Guide
For servicing, the top metal ticket guide can be removed and replaced. With unit facing you, gently spread side plates with thumb and index finger. Tilt guide to right at 45° angle and snap left side tab out and pull straight back. When replacing, simply reverse these steps. Note there is no need to spread side plates while replacing guide. Tilt to right and insert right tab first. Note: When PCB has opto-sensor cover, guide is inserted over sensor then directed down to right. Be sure guide is BELOW brake bracket screws when replaced.

2. Bottom Metal Ticket Guide
The longer, more durable ticket guide extends through the face plate allowing for better guidance plus a larger opening in the face plate prevents curled tickets from catching.

3. Loading of tickets with ticket advance switch
Tickets are inserted in the rear of machine between the top and bottom ticket guides and pushed forward to the rollers. If needed, gently push the locating spring (9) away from the ticket guides. Then push the ticket advance switch until you see the edge of first ticket.

4. Braking system
Our impressive braking system eliminates brake slippage allowing foolproof, accurate dispensing. The design also reduces wear and tear on the dispenser.

5. Brake bracket
The brake is easily accessible and can be adjusted to engage immediately when ticket is pulled. (Minimum of 1⁄8" from brake wheel.)

6. Opto-Sensor
Included as part of the controller is an opto-electronic beam sensor which detects the notch between tickets. The output of the ticket sensing circuitry is an open collector transistor.

7. Opto-Sensor Dust Cover
In addition, an optical sensor dust cover is also included to eliminate the possibility of ticket dust accumulating on the optical sensor. This increases the accuracy of the ticket count and reduces maintenance.

8. Roller Tension Spring

The roller tension springs keep constant tension on tickets which insures proper delivery and prevents the tickets from being “pulled through” when the dispenser is idle. To increase the tension, loosen the screw and move the spring forward. Tension is correctly adjusted when tickets cannot be pulled from the dispenser and validation rollers lightly emboss the tickets.

9. Locating Spring
The ticket guide spring insures that the notches in the tickets pass through the optosensor. To decrease tension, loosen the screw and move the outer tension spring up. This changes the tension on the inner spring. The tickets should be snug between the spring and the side plate but not deformed by the excess tension. The spring is adjusted at the factory for 1-5/32" wide tickets and positioned 1/8" from ticket guides.

10. “Quick Release” Face Plate
The dynamic design allows the ticket dispenser to “quickly release” from its face plate on your cabinet or ticket door. This can be done manually and no tools are needed. This gives you complete access to the front of the rollers and to the ticket guides. Plus you can “snap out” one ticket dispenser and immediately replace it with another in just seconds.

11. Ticket Stop Adjustment
The ticket stop adjustment allows you to position the tickets while the machine is off. The tickets should protrude through the slot at least 1/16". The ticket dispenser PC board is mounted on spacer with two screws with washers in two slotted holes. Loosening the screws and moving the board forward will allow the tickets to stop further out beyond the edge of the slot.

DL-1275 Quick Troubleshooting Guide

Use a Voltmeter to check voltages while blocking and unblocking the opto sensor (UI with a ticket)
1.TP1: No Ticket : 0.1V – 0.7V > OK
Ticket: 10V – 12V > OK
If NOT, replace H21A1.
3. TP3: No Ticket : 11V – 12V > OK
Ticket: 0V – 0.2V > OK
If NOT, replace U2.
U2 = 74C14 OR 40106
2.
TP2: No Ticket : 0.1V – 0.7V > OK
Ticket: 10V – 12V > OK
If NOT, replace 74C14.
4. TP4: No Ticket : 0.7V > OK
Ticket: 0V > OK
If NOT, Replace Q3.

Control Board

DL-1275 with 12V Meter Output

This dispenser is controlled by the game software. The game turns on the dispenser with a logic high signal and monitors a return notch signal fron the ticket dispenser to turn it off. It will diepense as many tickets as games options allow.

Notes:
1. Resistor RS and diode CR3 and the jumper going to pin 1 of the IC are changed for this revision. This was done to limit the current going through the switch and then to pins 1 & 9 of the IC. This resolves problems that occurred with units that used unregulated power supplies. Deltronic Labs still recommends that regulated supplies be used. Changes closely reflecting these changes were made in the previous revision. (Rev. 7)

2.  Resistors RI0. RI5. and R25 were deleted from this schematic. The Rev. 7 schematic shows these resistors, but they were never actually inserted on the board.
3.  The unit as shipped from the factory (as per this schematic), will trigger the counter whenever tickets are dispensed normally but NOT when doing so by pressing the switch. If desired, the unit can be changd so that tickets dispensed by pressing the switch are also counted. Do this by delieting diode CR5.

4.  This unit can be made to conform to CE specifcatlons by the addition of 4 components not shown here. If this is desired, please order the ALL CE version, and the unit will be shipped with the necessary components.
5.  This unit can be configured in a number of ways. Please check our "Full Options" schematic to see the different configurations. If this schematic is not included with your manual, contact us for a copy.

6.  If tickets are highly translucent, the 4.3 Kohm resistor R3 can be lowred In value
(e.g. 2.2 Kohm). For more sensitive adjustment, the jumper V 1 can be replaced with a 25K pot, and the 4.3 Kohm resistor (R3) changed to 1Kohm.
