Question 1

How to change the ink ribbon of the CASIO HR150RCE calculator for printing?

Accepted Answer

The CASIO HR150RCE is a 12-digit printing calculator equipped with 2-color printing (black and red) at 2 lines/s. The ink ribbon used is of the type IR-40T (or compatible equivalents IR-40TBK/IR-40TBR). To replace the worn ribbon and achieve clear printing, follow the steps below.

Preparation: Before starting, ensure that the device is turned off. Prepare the new IR-40 ink ribbon compatible with your calculator.

Step 1 – Access the ribbon compartment: Remove the currently installed 58 mm paper roll. Locate the transparent plastic disc that holds the ribbon in place, usually found on the side of the printing mechanism.

Step 2 – Remove the old ribbon: Gently pull the transparent plastic disc towards the paper roll to release it. Then, look for the tab marked "Pull Up" or similar on the old ink roll. Pull this tab to completely extract the worn roll.

Step 3 – Install the new ribbon: Insert the new IR-40T roll by aligning it correctly in its slot. Push it until it clicks into place. Ensure that the ribbon is taut and properly positioned between the guides.

Step 4 – Close the mechanism: Push the transparent plastic disc back into its original position, ensuring it holds the ribbon securely. Reinstall the 58 mm paper roll and check that everything is correctly assembled.

Step 5 – Test: Turn on the calculator and perform some calculations to print a test. Check that the printed text is clear and readable in both colors (black and red). If the printing remains faint or uneven, the new ribbon may not be positioned correctly.

Accepted Answer

The Casio HR150RCE calculator is equipped with a built-in clock that automatically displays the current time. However, unlike some other models of Casio calculators, this model does not have a function to manually set the date and time.
