Hantle 1700W Bill Creasing Error: Diagnostic and... | terminalfaults.org

Technical Background:

The Hantle 1700W dispenser utilizes a 24V DC solenoid-driven system to actuate rollers and belts for bill dispensing. Creasing can occur due to misalignment of rollers, worn belts, or foreign object obstruction. The system employs optical sensors to detect bill presence and movement; signal attenuation from dust or debris can lead to improper timing and errors.

Symptoms:

Bills are dispensed with creases from the Hantle 1700W dispenser mechanism.

Possible Causes:

Misaligned or worn dispenser rollers causing uneven pressure.
Accumulation of dust, debris, or foreign objects within the bill path.
Worn or stretched drive belts affecting bill transport speed and stability.
Solenoid malfunction leading to incomplete or erratic roller engagement.
Optical sensor contamination, resulting in inaccurate bill detection and timing.
Low 24V DC power supply impacting solenoid response.

Solution:

1

Power down the Hantle 1700W using proper Lockout/Tagout (LOTO) procedures.
2

Visually inspect the bill path for any obstructions (e.g., paper clips, debris). Remove any found.
3

Clean the dispenser rollers and belts with a dry, lint-free cloth. Avoid using liquids.
4

Check the tension and alignment of the drive belts. Replace if visibly worn or stretched.
5

Inspect the optical sensors for dust or contamination. Clean with compressed air.
6

Verify the 24V DC power supply output using a multimeter. Ensure it is within the specified range.
7

Power up the system and test the dispenser with a stack of new, uncreased bills. Observe for recurrence.

Safety Warning:

High voltage (120/240V AC) is present within the Hantle 1700W. Lockout/Tagout (LOTO) procedures are mandatory before performing any maintenance. Ensure the unit is properly grounded. Solenoids may generate heat; avoid prolonged contact. Do not use flammable solvents for cleaning.

Prevention:

Regularly clean the bill dispenser mechanism every month, especially in high-traffic locations. Implement a schedule for inspecting and replacing worn belts and rollers every 6 months. Ensure adequate ventilation to prevent dust buildup. Utilize bill stacks that are properly banded and free of excessive folds or damage.

Expert Tip:

Check for firmware updates from Hantle that may improve the dispenser's bill handling logic. Bill creasing can sometimes be mitigated with updated dispenser algorithms.

Frequently Asked Questions

•What is the recommended belt tension for the bill dispenser?

Refer to the Hantle 1700W service manual for specific belt tension specifications. Generally, the belt should have minimal slack but not be overly tight.

•How do I access the bill dispenser mechanism for cleaning?

Refer to the Hantle 1700W service manual for instructions on accessing the bill dispenser. This usually involves removing specific panels or components.

•What type of lubricant is safe to use on the dispenser rollers?

Do not use lubricant on the dispenser rollers. Dry cleaning is the recommended procedure.
