Stand on the item pedestal facing right. Perform a short stationary spin jump with some dash speed, and do a continuous wall jump off the item pedestal. Lay a Power Bomb (or Bomb) and use it to boost to the right, with a well-timed unmorph to reset fall speed.

It is ideal to gain 3 frames of dash speed, the maximum possible, but lower amounts can work. It is even possible to do a regular wall jump instead of a CWJ, but the CWJ makes it significantly more lenient. It is best for the wall jump to be performed as high as possible. If Speed Booster is available, equipping it will generally be helpful, as it will increase the height of Samus' wall jump based on the amount of dash speed.
