How to Calibrate 1Zpresso Grinder?

Calibration of 1Zpresso (Easy-presso) Grinders

Greetings, fellow coffee-lover.

There are three types of adjustment designs for 1Zpresso grinders, including internal adjustment, top adjustment and external adjustment. Many people might be curious about how to calibrate each of them. Therefore, today we’re going to explain to you.

How to Find the Zero Point / Starting Point?

First of all, we would like to define the zero point/starting point of our grinders. Turn the adjustment dial clockwise all the way to find the zero point/starting point of the grinders. We define it to be at the point when you feel resistance while turning the crank handle instead of the tightest of the adjustment dial.

Internal Adjustment

Q2 / JX / JE

For people who have Q2 / JX / JE, which are equipped with the internal adjustment, congratulations, you’ve already found the starting point by turning the adjustment dial clockwise till the crank handle won’t spin freely without any resistance. The numbers on the dial are designed for counting how many steps you’ve turned and therefore the starting point is not necessary to be at #0.

Generally, the top adjustment shares the same concept with the internal adjustment that the numbers on the dial are designed for counting how many steps you’ve turned and therefore the starting point is not necessary to be at #0. However, if you would like to set the starting point to #0, please follow the few steps below:

Step 1. When the dot points to #1/#2/#3 instead of #0 at the tightest, please simply remove the adjustment dial (by twisting it counterclockwise).

Step 2. Adjust the knurled thumb nut counter-clockwise by 1/2/3 clicks.

Step 3. Screw back the adjustment dial and the starting point should be at #0 (±2 clicks).

External Adjustment

K-Pro / K-Plus / K-Max

For K-Pro / K-Plus / K-Max grinders, to set your grinders to zero, please follow these steps:

Step 1. Before placing the inner burr in the grinder, tighten the adjustment dial counter-clockwise all the way and then to #0. Ensure the gap inside is fully closed and place the burr and the parts in the grinder.

Step 2. Push the burr all the way from the bottom and tighten the knurled thumb nut.

Step 3. The grinder should be calibrated now. If the red dot can still pass #0, loosen the adjustment dial a little and repeat Step 2 until the red dot aligns with #0.

External Adjustment

J-Max

For J-Max, to set your grinders to zero, please follow these steps:

The starting point should be where the #0 is aligned with the scale mark, and the bottom edge of the adjustment dial ring touches the first tier of the scale mark.

Tighten or loosen the knurled thumb nut while pressing the burr from the bottom to set the starting point to #0.

Note: There are four and a half rotations in total counted from the starting point. The starting point might be different within ±10 clicks due to the strength you tighten the nut and dial.
