How do I fix Canon error message 2700?

Resetting the waste ink absorber on a Canon printer can resolve some error codes that appear when turning it on.
  1. Make sure the printer is turned off.
  2. Press and hold the Resume button (triangle inside a circle).
  3. Whilst it is held down, hold down the Power button. The green led light should come on.

  5. Release the Power button.
  6. Press the Resume button four times and then press the Power button straight after to confirm the selected action (Reset Counter Absorber).

When im on browser everthing large and i pressed something on accident on setting while i was on internet and it wont go back to norman please help

If you mean you pressed something and everything you see now is LARGER... I've done that often. Easy fix.... hold down the "CONTROL" or "CTRL" as is is on my computer.... and while holding it down... hit the - (minus key one time). If still to big hit the key again while still holding down the ctrl key. The same can be accomplished to make things larger.... by doing the same thing.... (holding down the control key (ctrl) and hitting the + key one time. (or two times to make it smaller. Hope this fixes the problem.

How do i repair: hp Photosmart C7280 Printer ink system failure error: Oxc18a0101

Try holding down the ok -- cancel -- black -- color buttons with 4 fingers while at the same time powering the unit off. Keep them held down till it is off. Then turn it back on normally & it should try to do "Maintenance" & you hear a whirling noise --- that is the ink pump spinning to try & pump in ink to the print head.
Here are the details. Got the Ink System Failure message. The error code shows was '0xc18a0005'. The tech had me press and hold the '*' key on the key pad, then press the '#' key and release them both. Then he had me enter '123' to enter maintenance mode. He then had me press the right arrow (beside the OK button) until System Config. menu appeared on panel. Then pressed OK two times to clear the error condition, then cancel two or three times to return to the top menu. Then powered off and back on, printed a test page just fine, copied a document fine.

Has new battery and wont turn on

Hello, You can try to perform the self-test. Procedure is as follows. To perform the self test on units with two batteries:
  1. Turn the calculator off.
  2. Press and hold the c01788482.jpg and c01774569.jpg keys; keep both keys held down for the next step.
  3. Press the c01788481.jpg key so the c01788483.jpg and c01788481.jpg keys are held down simultaneously.
  4. Release the c01788481.jpg key.
  5. Release the c01788482.jpg key, followed by the c01774569.jpg key. The main test screen displays the following: '1.L 2.C 3.H'.
    • Press c01788484.jpg to perform the LCD test (all LCD segments will be turned on). Press any key to exit.
    • Press c01788485.jpg to perform the checksum test and see the copyright messages. Press any key to go from one screen to the next until the main test screen, '1.L 2.C 3.H', is displayed again.
    • Press c01788486.jpg to perform the keyboard test. Press EVERY key on the keyboard until all the keys have been pressed at least once. The screen will progressively turn off with each key press. Once all the keys have been pressed and the screen is clear, press any key to return to the test screen.
Press c01788481.jpg to exit the test system. This will also turn the calculator off. If the calculator detects an error at any point, it will display an error message. For the HP 12c financial calculators with one battery, to perform the LCD self test:
  1. Turn the calculator off.
  2. Press and hold the c01788480.jpg key, and simultaneously press and hold the c01788481.jpg key.
  3. Release c01788481.jpg then c01788480.jpg .
  4. After a few moments, all elements of the screen should be displayed. Press any key to exit.

Continual pop-ups saying OSD Main Control locked followed by language choice, etc. I have tried the buttons on the monitor with no effect

I held down the OK button for several seconds and the message vanished. On releasing the OK button, the problem reappeared. I intend to put a rubber glue (one that can be removed) which hardens on application, to hold down the OK button in the pressed position. Hope this solves the problem.
