Cale CWT Compact: Ticket Roll Jam - Diagnostic and... | terminalfaults.org

Technical Background:

The CWT Compact utilizes a 24V DC motor to drive the ticket dispensing mechanism. An optical sensor detects ticket presence. Mechanical encoders track roll advancement. Logic controller monitors motor current; increased current indicates a jam. Environmental factors like extreme cold (-40C) can impact material properties (paper brittleness, lubricant viscosity), influencing jam probability.

Symptoms:

Ticket roll fails to advance. Display indicates paper jam error. No ticket dispensed upon request.

Possible Causes:

Ticket roll misaligned within the holder, causing friction.
Ticket stock is of incorrect specification (weight, thickness) or damaged (moisture absorption).
Motor drive system experiencing mechanical wear or failure (reduced torque).
Optical sensor malfunction or obstruction preventing ticket detection.
Accumulation of paper dust or debris within the ticket path.
Solenoid controlling ticket cutter mechanism failing to fully retract/extend.

Solution:

1

Inspect ticket roll alignment within the holder. Ensure it is seated correctly and rotates freely.
2

Verify the ticket stock meets the Cale CWT Compact specifications (size, weight, material). Replace if necessary.
3

Power cycle the CWT Compact (remove and reapply power). This may reset the system and clear minor jams.
4

Access the diagnostic menu (refer to the Cale CWT Compact service manual for key sequence) and run the ticket dispensing test.
5

Using compressed air, carefully blow out any accumulated paper dust or debris from the ticket path.
6

Visually inspect the optical sensor for any obstructions or damage. Clean the sensor lens with a dry, lint-free cloth.
7

If the issue persists, contact a certified Cale technician for further diagnostics and repair.

Safety Warning:

Ensure the CWT Compact is disconnected from the power source before performing any maintenance. Do not use liquids to clean internal components. High voltage components are present; avoid contact. Follow Lockout/Tagout (LOTO) procedures to prevent accidental energization during maintenance.

Prevention:

Regularly inspect ticket rolls for damage or misalignment. Clean the ticket dispensing mechanism every three months using compressed air. Verify ticket stock meets specified requirements. Implement a preventative maintenance schedule.

Expert Tip:

Before replacing the ticket roll, check the roll direction. Incorrect roll direction can cause unnecessary friction and lead to jams. Use a small, angled inspection mirror to check the optical sensor without disassembling the unit. Often, a small piece of debris is all that's required to cause a sensor malfunction.

Frequently Asked Questions

•What are the recommended ticket stock specifications for the Cale CWT Compact?

Refer to the Cale CWT Compact service manual for detailed ticket stock specifications, including size, weight, and material type.

•How do I access the diagnostic menu on the Cale CWT Compact?

The diagnostic menu access procedure varies depending on the CWT Compact firmware version. Consult the Cale CWT Compact service manual for the specific key sequence.
