Patricia, Using the power switch, you can forcibly reset your Kindle device. This reset will shut down the Kindle without accessing the shutdown command from within the Kindle's operating system, a particularly useful tool when dealing with a frozen Kindle. To initiate a hard shutdown, Kindle disconnect from its charger, slide and hold the power switch for about 20 seconds. This will force the Kindle to shut down, now it can be restarted normally.

press ink change button and while printer is checking if ink is ok press and hold power button for 10 second (it won't shut down the printer) and let go. then it will shut down by its self. turn it back on and printer will go through some checking (more then usual) and then it will see all ink cartridges. If that won't help your cartridge is not genuine.

There is one thing you can attempt before seeking repairs. You should try a power reset.

1) Unplug the AC adapter
2) Remove the battery
3) Hold down the power button for 30 seconds and then release it
4) Insert battery
5) Plug in AC adapter and see if the laptop can power on

If it does not power on, you may need to seek support with Acer.

check your power supply...

It sounds like a switched power or constant power issue have you checked the fuses. Their is all so a fuse behind the radio. Just unplug the harness going to the radio and it is behind that.

It sounds like there may be an electrical leak, If the voltage goes too low, the computer either shuts down or it can go stupid where certain things won`t operate. Try turning everything off, disconnect the positive lead from the battery and connect an ammeter between the positive terminal of the battery and the positive connector that goes to the bike. There should be very little drain from the battery, (I presume it`s got a clock and maybe a radio with presets that require power). I would say if there is more than say 10 - 50mA showing on the meter, you`ve got a leak. I`ve just been explaining about one of these bikes where it was the rectifiers that were leaking. I`m only guessing so I hope this helps. Ian

When the plotter goes through its initialization, it stops, the printheads move to the right side and the window displays "switch power off, check printhead path (2)" I've turned the power of an wiped things down, I've unplugged and then restarted but continue to get this message. What do I need to look for or do to get it back on track?

need new batteries.
