    4525 ITB Reset

    I've seen a few HP CP4525 transfer belts fail to reset the life count to 100%. If this happens the New ITB flag will be in the "tripped" position (see photo). Use the following procedure to reset the flag on the ITB so it can be reinstalled and trip the printer's "New ITB sensor" flag.

    1. Clean the New ITB sensor flag thoroughly with canned air and pull the flag toward you to make sure it swings freely. It's on the right, near the cyan drum. (see photo: ITB sensor.jpg)

    2. Use a pen or paperclip to press in the center hole on the side of the new ITB while turning the white Alienation Gear clockwise. (see photo: ITB flag reset.jpg)

    3. After a few turns the ITB reset flag will reappear. I prefer leaving it at an angle as shown rather than at 90 degrees. This minimizes the chance of accidentally tripping it.

    4. Insert the new ITB and turn power on. It should start callibrating. If it doesn't, repeat the process.

    5. Print a supply status page to verify that the ITB life is at 100%.

    Great!
    BTW, this fix also works on the CM4540 and the CP4020 series.
