Hello well the blinks go 3 blinks then stops and 3 again,

Shows normal operation

Google the model number with 3 blinks or error codes and you should find it.

hello
1- you check thermostat .
2-maybe temp your house is below 26c.
3-you check fan condenser and evaporator .
4-maybe cut off low pressure system.

1. push the clock button 2. display should be blinking. 3. then push 3, then 0, and 0 again (this is for 3:00) 4. then push the clock button again, and it should be set     again. 5. sometimes, by doing just the first 3 steps and letting     it be until the blinking stops, is another way. But             most likely, you'll need to follow through to step 4

Hello.

From Canon:

Probably your waste ink counter. Should be cleaned or replaced before resetting but usually you can get away with resetting once.
1. Start with printer OFF
2. Hold down RESUME and then hold down POWER
3. Release RESUME
4. press RESUME twice, then release POWER
5. let green light blink until printhead has finished moving.
6. Select functions below with RESUME, execute with POWER

0 presses - green light - Test Print
1 press - orange light - EEPROM info print
2 presses - green light - EEPROM initialise
3 presses - orange light - reset waste ink counter.

Hope this helps.

When looking at the face, you have 4 pushers. Top left is for regatta function countdown. Top right is regatta function start-stop-reset. Bottom left is Hours-Minutes and Nite Lite. Bottom right is regatta function "catch up". Assuming that you want to set Hours and Minutes, press and hold the bottom left for 3 seconds...Hours will start blinking, press the pusher successively until the desired hour is reached. Then wait until it stops blinking. To set minutes, press and hold for 3 seconds, the hours will again begin to blink, then release and re-press for an additional 3 seconds and the minutes will blink, Then press successively until desired minutes have been reached. Stop pressing and wait until the blinking has stopped. Once it has stopped blinking your time has been successfully registered. Good Luck. Hope this helps!
