Question 1

How to insert flat labels into the CITIZEN CL-E300 thermal printer?

Accepted Answer

To use flat labels (not on a roll) with the CITIZEN CL-E300 thermal printer, follow these steps:

1. Remove the label roll

Open the printer cover and remove the holder containing the currently installed label roll.

2. Prepare the flat labels

Ensure that your flat labels are size-compatible with the printer. They should be well-aligned and flat to avoid jams.

3. Insert the flat labels

Place the labels in the designated compartment, ensuring they are properly positioned against the media guides.
Adjust the side guides to hold the labels firmly without bending them.

4. Configure the printer

Change the printer settings to indicate that you are using flat labels and not a roll. This can be done via the control panel or the associated software.

5. Close the cover and test

Close the printer cover and run a test print to check that the labels are correctly fed and printed.

By following these steps, you should be able to print on flat labels with your CITIZEN CL-E300 without any issues.

Question 2

What does the RCL + B button combination do in standard deviation mode on the CITIZEN SR-270N watch?

Accepted Answer

On the CITIZEN SR-270N scientific calculator, in standard deviation mode (SD mode), the button combination RCL + B allows you to recall and display the population standard deviation value (Xσn) of the entered data.

This function recalls the statistical variable Xσn, which represents the population standard deviation calculated from the entered data. Unlike the previous response, RCL + B does not reset the data, but simply extracts it for display.

Procedure:

Make sure you are in SD mode: press [ MODE ] then [ 2 ]
Before starting a new series of calculations, clear the statistical memory with [ 2nd ] [ Scl ]
Enter your data with [ DT ] (for each value)
Once the data is entered, press [ RCL ] [ B ] to display the value of Xσn (population standard deviation)

Differences with Xσn-1: This calculator also offers [ RCL ] [ C ] which recalls Xσn-1, the sample standard deviation, calculated with the divisor (n-1) instead of n. The choice between Xσn and Xσn-1 depends on your statistical context.
