The design of the 1Zpresso bands is to attach to the grinder allows for better hand grips. The grinder won’t slip out your hands when grinding the coffee beans.
Before Installation
The grinder needs to disassemble in order to install the bands.
The ideal location would be the top or middle body of the grinder. It is supposed the location that most of the users would grab during grinding the coffee beans.
The diameter of JE-Plus grinder considerably is large for some coffee users. Attaching the bands on the grinder would resolve this issue.
I must admit that we did amaze by the creativity of the customer. For instance, put the brands onto the catch-cup to reduce the damage in case of the catch-cup falls on the floor.

How often that you clean your 1Zpresso manual coffee grinder? Proper maintenance could prolong the life of your grinder for a long period of time. We advise customers to dismantle the grinder once a month to perform cleaning and maintenance. The grinder could dismantle without any helps from the tool.
Here is a reassemble tutorial for the top adjustment mechanism of K-Pro & K-Plus grinder. You also can find the cleaning and maintenance tutorial of the internal adjustment and top adjustment from our blog. Below image demonstrating the re-assembly with K-Plus grinder.
Step 1:
Remove the crank handle and the catch-cup.
Step 2:
Pressing the burr set and loosen the knurled thumb nut by turning counter-clockwise.
Step 3:
Take out the burr set by pressing down the central shaft. Collect the upper ring cap and the upper bearing which inside of the adjustment dial ring.
Step 4:
The adjustment dial ring and the outer burr ring can be taken out by turning clockwise. (For K-Pro grinder user: Attaching the catch-cup to remove the outer burr ring by turning clockwise.)
Note: the outer burr ring unable to remove without taking out the burr set.
The magnetic catch-cup of K-Plus grinder could be dismantled in three parts. Remove the magnetic attachment ring by turning counter-clockwise. Turn counter-clockwise to separate the closed receiver from the open receiver.
Perform the step reversely to recover the catch-up.
Press to remove for throughout cleaning.
Step 5:
Take out the pc lid by turn counter-clockwise throughout cleaning. Apply some strength to detach the wooden ball.
Clean it with the brush & air blower and be sure do not to apply water to wash it.
Step 5.1
There is another design of the crank handle. It needs a 6mm hex key/Allen key to remove the pc lid by turning counter-clockwise.
Step 6:
Put the wooden ball into the crank handle till you hear a click sound and tighten the pc lid by turn clockwise.
Turn the outer ring burr and the adjustment dial ring counter-clockwise to secure.
Step 6.1:
Followed by step 5.1. Apply a 6mm hex key/Allen key to install the pc lid by turning clockwise till it tightens.
Step 7:
Place the pieces in order to ensure the grinder works perfectly. The central shaft and the burr set fixed together, you need to put it back into the grinder. Before that, you have to place the spring then the bearing cap on the burr set.
Note: the spring is the conical shape in which you need to place the larger surface upward as the opposite of the smaller surface and the protruding side of the bearing cap consider facing upward.
Step 8:
Insert the upper bearing into the adjustment dial ring. Now it is a tricky part, you would notice there is a horseshoe shape appearing from the upper bearing cap. The flat side from the upper bearing cap needs to match the flat side of the central shaft as well.
Step 9:
Pressing the burr set and tighten the knurled thumb nut by turning clockwise till you feel a resistance (do not overtighten or it hurt the burr set).

Greetings, fellow coffee-lovers. Here we go again.
We consider ourselves a player-type manual coffee grinder company as we are constantly improving the features of the manual coffee grinder based on the feedback from our beloved coffee-lovers.
I could think of the most common question that we’ve received is:
How to choose a 1Zpresso manual coffee grinder? There are so many of em. What’s the difference between K-Plus and JE-Plus, I am so confused. How do I perform the grind setting adjustment? The mystery had solved. How do I calibrate my 1Zpresso manual coffee grinder? Another mystery had solved. How do I clean and maintain my grinder? (Internal adjustment & Top adjustment & External adjustment)
There are three kinds of adjustment settings from 1Zpresso manual coffee grinder, the classic internal adjustment design (Q2, JX, JE, JS grinder), the minor upper adjustment design (JX-Pro, JE-Plus grinder), and the proudly announced awarded external adjustment design (E-Pro, J-Max, K-series – K-Pro & K-Plus grinder).
Besides the Accessories are included in the Pro and Plus tiers grinder. We are going to reveal all the features of the 1Zpresso manual coffee grinder to clear your wonder.
Q2 Grinder One of the favorite items to go camping and hiking with. Nothing beats glazing over the horizon on top of the mountain when you enjoy the coffee-break. A friendly travel-sized grinder with a 38mm burr size could fulfill your daily pour-over coffee needs.
JX Grinder I would recommend JX grinder to the coffee-lovers who’re mainly brewing pour-over. It employed the large burr as 48mm and the classic internal adjustment resulted in greater grinding efficiency.
JE Grinder I would suggest JE grinder to the coffee-lovers who’re mainly brewing espresso. It is equipped with the burr size of 47mm and the classic internal adjustment.
JE-Plus Grinder The premium version of JE grinder. The Itamill-coated burr set is 47mm and the minor top adjustment design has 12.5 microns per click and the magnetic catch-cup is ideal for brewing espresso and works well with 51mm and 58mm portafilter.
J-Max Grinder The latest espresso grinder from 1Zpresso. J-Max grinder with Coated-Burr design and the Magnetic Catch-cup design. The External Adjustment with 90 clicks/9 numbers per rotation, 10 clicks per number and 8.8 microns per click. It is the most extreme fine adjustment where you could taste the sweet spot of espresso.
JX-Pro grinder The advanced version of JX grinder, it shares the same burr design as 48mm, except for the adjustment design. The overall grinder with the fine adjustment design (12.5 microns per click).
K-Pro grinder The visible external adjustment with 90 clicks per round and the grinding efficiency as the specialized K Burr with 48mm.
K-Plus grinder It has the same external adjustment design with 90 clicks and the specialized K Burr with 48mm as K-Pro grinder and the same magnetic catch-cup design as JE-Plus grinder with a capacity of 35~40g.
The Grinding Result of 1Zpresso Grinder
We ran some grinding tests for the grinders with the 15g light-roasted coffee beans on Nov 19, 2020. We thoughts it might help the coffee-lover to clear the wonder about the grinding consistency, it is not a professional test for particle distribution though.
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 clock-wise all the way to find the zero point / starting point of the grinders. We define it to be at the point which the crank handle won’t rotate drastically instead of its tightest.
Internal Adjustment
Q2 / JX / JE
For people who have the 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 rotate drastically. 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.
Top Adjustment
JX-Pro / JE-Plus
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 nut (by twisting it counterclockwise). Step 2. Adjust the knurled thumb nut counter-clockwise by 1/2/3 clicks. Step 3. Screw back the adjustment nut and the starting point should be at #0 (±2 clicks).
External Adjustment
J-Max / K-Pro / K-Plus
For the J-Max / K-Pro / K-Plus, to set your grinders to zero, please follow these steps:
Step 1. Tighten the adjustment dial counter-clockwise and ensure the gap inside is fully closed.
Step 2.
If the red dot is at the right of #0, loosen the adjustment dial clockwise a little bit, loosen the knurled thumb nut counter-clockwise and re-tighten the dial while pressing the burr from the bottom.
If the red dot is at the leftof #0, note the clicks of distance from #0 (for example, 12 clicks), loosen the adjustment dial clockwise a little bit, and tightened the knurled thumb nut counter-clockwise by 12 clicks while pressing the burr from the bottom.
Step 3. Repeat step 1 and 2 until the red dot points to #0.
Do you know how to read the grind setting reference of the 1Zpresso manual coffee grinder? Here is the tutorial for y’all to learn.
I personally tired of carefully adjusting the grinder when there are many clicks without knowing where it was.
All the burr in the grinder was calibrated by the 1Zpresso team to ensure maximum stability over time. The outer ring and the burr were built through precision finishing so tolerance was expected as the first few clicks of the outer ring and the burr would touch. The constant touching will damage the burr set.
It is effortless to observe the external adjustment design, where you could just notice the red dot point.
I reckon it is easy for the internal and top adjustment design as well, you adjust the adjustment dial clockwise till you feel a resistance to stop, that’s the zero settings.
These three kinds of adjustment design share a common point on representing your grinder at zero settings: the crank handle is unable to move drastically.
