Value input mode becomes active when configuring settings such as paper size or copy zoom ratio. In this mode, use the keys as follows:
To enter a digit
Press a number key. Press the number keys successively to enter a multi-digit number.
To increase or decrease the current value in units
Press the  keys. The unit of increments depends on the setting you are configuring.
If a digit is entered more than three seconds after the last input, the entered digit replaces the current value.
When the maximum number of digits has already been entered, the next input digit replaces the current value.
If the current value is too large or too small for the current setting, it will not be accepted. In this case, pressing the  or  key changes the value to the minimum or maximum value for the current setting, respectively.
