4-10-1 Timing and precautions when removing the memory card
The following timing and precautions are suggested to protect the memory card data.
- Remove the memory card while the Access lamp is not lit. (If the memory card is removed while the Access lamp is blinking or on, the data on the card is not
assured.)
- When the printer is not connected to a host computer, power off the printer with the Power button and after the Access lamp is not lit, remove the memory card.
- Remove the memory card together with the adapter, not the memory card only.
- When the printer is connected to the host computer, from the host computer, select "Eject disk" to turn the Access lamp off, and then remove the memory card.
(Turning off the printer also turns off the Access lamp, however, the incorrect disk removal warning message may be displayed in the connected host computer.)
When using Windows, and the memory card drive is displayed in Explorer, close the window prior to removing the memory card. (If the window is not closed
prior to removing the memory card, the following phenomenon will appear in the host computer.)
WindowsMe/98: A blue background screen appears. This can be recovered by following the instructions in the display.
Windows2000/XP: A warning is displayed, and the "Eject disk" operation cannot be executed.
