Preparing to Print
RAW images are not compatible with direct printing.
If you use a battery to power the camera, make sure it is fully charged.
With a fully charged battery, printing up to about 4 hours is possible.
If there is a long beeping sound in step 5, it indicates a problem with the
PictBridge printer. To find out what’s wrong, do the following:
Press the button to playback the image and follow the steps below.
1. Press <0>.
2. On the print setting screen, select [Print].
The error message will be displayed on the LCD monitor. (p.138)
When connecting the camera to the printer, do not use any cable other
than the dedicated interface cable.
After printing starts and while the button’s blue lamp blinks, do
not unplug the cable.
Before disconnecting the cable, turn off the camera and printer first. Pull
out the cable while holding the plug, not the cord.
For direct printing, using AC Adapter Kit ACK-DC20 (optional) to power the
camera is recommended.
