I have a cannon inkjet mp560. when ever I try to print it says "printer is offline" or "printer is not responding. I've tried unplugging the usb cord and turned it off and restarted it, but it will not work. please help.

You did not specify if printer was formerly working, the model # of the printer, or what version of Windows you are using. All this information is needed for successful troubleshooting. However, the below is general resolution for your problem:

"Offline" means your computer cannot "see" the printer as connected and powered on.

In order of things to try:

1. Turn printer OFF. Unplug USB cord from printer (or other end from computer). Wait at least 30 seconds. Plug USB cord back in. Turn printer back on. Does it still show as "offline" under Start --> Devices & Printers?

2. Try replacing the USB cord (yes, they can and do go bad).

3. Turn printer off. Unplug USB cord.
Under Windows Start --> Printers and Devices:
RIGHT click the Konica printer icon. Select "uninstall" (or "remove device") and follow through until printer is successfully UNinstalled. If there is other Konica software installed, remove it also (via Start --> Control Panel --> Add/Remove Programs -or- Programs & Features).

4. Reboot your computer. Follow manufacturer printer installation procedure, step-by-step (consult mfr website if you do not have a printed installation manual). Do not plug in USB cord or turn on printer until instructed to do so.

If all else fails:

Ignore any manufacturer installation instructions.
Do # 3 only above.
Reboot computer.
Plug in printer and connect it to computer.
Let Windows try to automatically install it (in most cases, Windows can install the "basic" print drivers, which are smaller and sometimes more stable than the fancy drivers and excess software the manufacturer wants you to install).

If still no go, you probably have a dying or dead printer. Consult manufacturer website for help.

Please also check whether USB cable is good. Did you compare it with other USB cable?

Try this. Disconnect printer from computer
2. re- connect after a minute.
3. from tools menu, clean cartridge.
4. now allign cartridges from the same tool menu.
5. complete allignment process as directed.
6.now try test print.

If it has worked before try power off, unplugging the power cord and USB cord from the printer. Wait 1 minute then reconnect cords and power back on. If wifi only, try a wifi power off/on.

it sounds as if one or more of the nozzles of your printhead is dried or blocked. I would advise printing printing a test page like this one to clarify the cause.

Assuming one of the colours is missing (i would imagine it would be cyan or yellow) then run some head cleans from your printer software or the printer itself.

This may be a longshot, but many electronic devices like TVs, dryers with electronic computerized controls, entertainment systems like the Wii, and other devices sometimes get "confused" and won't turn on, turn off, or otherwise work properly, perhaps due to a small power surge in your AC line.

I've found that one of the first things to try when it appears to be a failure of the electronics and not a mechanical issue is to unplug the device at the wall (to make sure that any power adapter is also unplugged) and wait about 10 minutes for any residual electric charge to dissipate. Then plug the device back in and give it a try. This has worked with a television, a Wii console, an electric clothes dryer, and some other devices that I thought had died for good. This may explain why sometimes a device is taken to a repair shop and it works fine.

There are, of course, other reasons that the unit won't turn on, but I would try this first before looking for other reasons for the problem.

I'm going to try a new power adapter.

Sometimes a printer will go to work offline and not realize its still offline when you turn printer back on.
If you can see a printer icon in your tray (bottom right) then double click it and you see a windows similar to the one screen shot below and click on "printer" menu and uncheck "use printer offline".
If that still doesn't work then delete the job in the queue and try to print again.

Hello
I would try to reinstall the printer driver on your computer, as the printer might be working fine.
You can go to cannon's support site to downoad the driver you need:

Hope this helps

when you disconnect the printer from your pc does it make a sound? also check File - Print - ( is the printer you are using highlighted? If no, right click and set as default. If yes, right click and see if it says "ready" when disconnected it should say "offline"
Which means the USB and the connection is OK
Look at the bottom right ot the screen is there a printer Icon there? if yes right click and see if there are any jobs pending, delete all jobs.
Otherwise it may be the driver which you may have to re-install.
