Here's a breakdown of the potential causes for button and printing failures on a Casio HR-100TM calculator, along with troubleshooting steps:

1. Button Issues

Dirt and debris: Dust or crumbs can get under the keys, preventing them from making good contact.

Solution: Clean around the buttons carefully with a soft cloth, cotton swab, or compressed air. A little isopropyl alcohol on the cotton swab can help if there is more stubborn residue.

Worn contact pads: The conductive pads under the keys can wear down over time.

Solution: This requires disassembly and either cleaning the pads thoroughly or possibly replacement. This is more complex, and a technician might be needed.

Circuit board damage: Corrosion or damage to the calculator's circuit board can break the connection.

Solution: Requires disassembly and inspection. Repair or replacement of the circuit board might be necessary.

2. Printing Issues

Out of paper: The most simple solution!

Solution: Ensure you have a compatible paper roll inserted correctly in the printer compartment.

Ink ribbon depletion: The ink ribbon might have run out entirely.

Solution: Replace the ink ribbon with a compatible one.

Jammed paper: Paper can become stuck or misaligned in the printer mechanism.

Solution: Carefully remove any jammed paper and ensure the paper is feeding correctly.

Mechanical problems: Worn gears or other internal components of the printer could be failing.

Solution: Disassembly and inspection will be needed. Some parts might be replaceable, but major damage would be difficult to repair.

Troubleshooting Steps

Basic Cleaning: Start by cleaning the calculator thoroughly, especially around the buttons and the paper compartment.

Check the Paper and Ink Ribbon: Make sure these are in place and not depleted.

Reset: Find the small reset button (often on the back) and press it with a paperclip. This resets the calculator's settings but won't fix hardware issues.

If problems persist:

Refer to Manual: Your Casio HR-100TM manual might have more extensive troubleshooting guides. You can find it online https://www.manua.ls/casio/hr-100tm/manual

Seek Repair: If cleaning and basic steps don't help, it likely indicates a deeper hardware issue. Consider a qualified electronics repair shop if the calculator still has value to you.
