"Turn Power Off then on Again" error

I've checked all of the cords and there is nothing obvious wrong with the printer, but it's giving me the "Turn Power Off then on Again" message... everytime I restart. I've unplugged and repluged a few times as well and the message keeps popping up. Anyone?

Try performing a reset on the device. Unplug the power cable, then hold # and 3 while powering it back up.

2. Open the cover of the product and remove the print cartridges.
3. Close the cover and wait for the Insert Ink Cartridges message to display.
4. Disconnect the power cord from the back of the product and wait for one minute.
5. Reconnect the power cord. If the product does not automatically turn on, press the Power button.

The red triangle light with the "!" in it keeps flashing. I've just printed some things off but now it's not printing. Need it to print obviously..


ATTENTION light(triangle): Indicates that the print-cartridge door is open, print cartridge is missing, and other errors.

If ATTENTION and READY light is blinking:

Printer initialization
The printer is initializing.
No action is necessary.

Cleaning mode
A cleaning page is printing.
Wait until the cleaning page has finished and the printer is in the Ready state.
This could take up to two minutes.

If ATTENTION and READY light is on:

Fatal error
Turn off the printer, and then unplug the printer power cord for 30 minutes.
Plug the printer power cord into the power outlet, and then turn the printer on.
If the error persists, replace the printer.

If ATTENTION light is blinking and READY light is off:

  1. Attention: door open, no print cartridge, or media jam
The printer is in an error state that requires operator intervention.
Check the following:
? The print cartridge door must be completely closed.
? The print cartridge is correctly installed.
? There is no media jam.

2. Out of memoryThe printer is out of memory.
The page you are printing might be too complex for the printer's memory capacity.
Try lowering the resolution.

False paper jams--tried cleaning, reset, etc. Nothing seems to work


Have you tried this method? (listed below), if not, give it a try.
Remove all the cartridges, clean the contact points on the cartridges and on the printer using soft brush/cotton dipped in alcohol/acetone /spirit.
While they are drying, reset your printer; Turn it off > Disconnect usb cable, power cord, inthernet cable; >remove the papers from the tray >open the back panel door (the rear door where you clear paper jam). Also turn of the main switch which the dc adapter plugged in. After keeping it Off for about 5 minutes, turn on again using only the power cord, and again leave it on for few minutes > turn it off > connect all the cables > again turn it On and keep pressing the power button while it boots up. Now you can install the cartridges.

If there's not internal problem or wrong cartridges number, then your problem will be definitely fixed.

Good luck.

Thanks for using FixYa.

Just replaced the ink cartridges. Printer keeps telling me to turn it off then on. However, it fails every time I turn it on again.


With the power cord connected and the unit on, disconnect your data cable(s) from the printer (USB, parallel). Press the power button to turn off the unit; wait 15 seconds and then turn the power on again.

Check if the error comes back. If it doesn't, reconnect your data cable(s) one at a time, checking for the error message between adding each connection. If you see the error, replace that cable.

If the error did come back after cycling the power when no data cables were connected, you have to look at your power cable. If the cable has a power module (box that you plug another cord into), make sure that you have the correct one for the printer.

In either case, unplug the power cord from the back of the printer (first) and unplug it from any surge protector or power strip (second). If you have a power module, unplug the cord from that and reconnect. Wait 30 seconds. Plug the cord directly into the wall outlet and then into the back of the printer. Then turn on the printer.

Check for issues. If the printer turns on, you may have overloaded the power strip. If it doesn't turn on, you should check the outlet for problems. Try using an outlet in a different room (preferably a different circuit breaker). (Move the printer and its power cord.) If the printer still doesn't work, replace the power cord or module.

If none of the above works, the printer needs service.

I hope this helps.

It keeps giving the alert wrong cartridge and wont print.I installed for the 1st time ink power cartridge instead of canon's and it won't do nothing........... these cartridge are half price but look...


Wrong cartridge refers to the printhead and not the inks. This machine, when the printhead goes bad gives that error. A new printhead is around $60.00 for that machine. QY6-0064-000.

Printer wont turn on


First things to check are that the power cord is properly plugged in and the socket it turned on (yes, sounds obvious but has caught me out in the past).

Beyond that, if your cable has a fuse in the plug, check that... try a different power cord and obviously check that the socket does indeed work.

Locating a working power socket and new cable that you know works and then seeing if that gives you any juice is the only other option... If that doesn't work your printer would appear to be in printer heaven.

Solution
  1. Press the On button to turn the printer off.
  2. Unplug the power cord from the back of the printer.
  3. Remove all the ink cartridges.
  4. Wait two minutes.
  5. Plug the power cord into the back of the printer.
  6. Press the On button to turn the printer on.
  7. Install the ink cartridges when prompted.
If the error code does not display, the issue is resolved. If the 0xc18xxxxx or 0xc19xxxxx ink system error code displays on the front panel, service the printer.
