For more information on how to install the battery, see the documentation
that came with the battery.
Check that the printer power cord is securely connected to both the printer
and the power source. When the printer is turned off, the printer battery light
on the control panel flashes green to indicate that the battery is charging.
Turn on the printer. The printer battery light flashes on the control panel to
indicate that the battery is charging.
An empty battery should fully charge in approximately four hours when the
printer is not in use. If the battery still does not charge, replace it.
The printer makes noises when I turn it on, or starts making noises on its own
after it has been sitting unused for a while.
Solution The printer may make noises after long periods of inactivity
(approximately 2 weeks), or when its power supply has been interrupted and then
restored. This is normal operation—the printer is performing an automatic
maintenance procedure to ensure that it produces the best quality output.
The remote does not work.
Cause
The battery in the remote may be drained.
The Output tray is closed.
Solution
Purchase a new CR2025 battery and replace the old battery with it.
Open the Output tray. The infrared sensor is on the front of the printer. The
remote cannot communicate with the printer if the Output tray or anything
else covers the sensor.
Aim directly at the infrared sensor on the front of the printer. Move closer, if
necessary.
Remove anything that might be covering the sensor or obstructing the line of
sight between it and the remote.
The camera buttons are not working.
Solution You are pushing buttons on the camera after it is placed in the camera
dock. Most camera buttons are disabled when the camera is in the camera dock.
Use the buttons on the control panel instead.
The printer does not recognize the PictBridge camera connected to the camera
port.
Cause The HP Photosmart 420 series GoGo Photo Studio camera was already
in the camera dock when you connected the PictBridge camera to the camera
