5First running
5.1 Filling the canister
Open machine door with keys
Open machine cover
Wear a mask and disposable edible gloves.
Open the top cover of the material box and add the powder corresponding to the material box.
Note:
When the machine is filled for the first time or after cleaning, it needs to be tested several times to ensure
that the canister outlet is filled.
The machine can only run properly if the powder is replenished in time.
6Adjustment and calibration
6.1 Grinder fineness adjustment method
To adjust the coarseness of the grind according to the
silkscreen diagram.
Before filling beans, firstly screw the knob clockwise to
the position of the disc fit (normal torque cannot be
screwed ), Second rotate the knob counterclockwise for
16 turns, as a benchmark coarseness position (general
espresso coarseness), final in the calibration process
according to the fineness of the powder and then
fine-tuning (clockwise direction is to adjust finer,
counterclockwise is to adjust thicker )
1. key unlock
3.open cover
2. open the door
4. place coffee hopper

14
6.2 Grinder calibration
The calibration software is for the physical characteristics of the instant canister powder, the
physical characteristics of the powder and the degree of roasting of the coffee beans. Before
calibration you need to prepare the electronic scale and cups.
Important:
No calibration will result in abnormal machine output!
Make sure that the canister outlet is filled before calibration, which can be achieved by the "Start
Test" function, as an insufficient outlet will lead to inaccurate calibration.
Note:
Because each part or powder has different physical characteristics, so every time you replace the
canister, motor or different manufacturers of coffee beans and powder, you need to recalibrate,
and the amount of powder in the canister should be greater than 1/3 of the volume of the
canister during calibration.
After the grinder adjustment is finished, you need to calibrate the amount of coffee powder.
Press and hold the top left corner of the screen, enter the password in the pop-up dialog box,
administrator password: jn9527 or maintenance password: 9527.
Enter the machine background "coffee machine" interface.
In the “Status”-“Canisters Management”-“Fill”, select “coffee bean”, click , in the pop-up dialog box
“Filling” enter the weight of the coffee beans poured into the coffee bean hopper, click “save”.
Find the coffee bean column in the “Status”-“Canisters Management”-“CAL.”, click on the calibration
icon ; in the pop-up dialog box "Output time" (range is 1-10 seconds, usually enter 2-3 seconds),
click "Start testing". Twice, discard the ground coffee powder!
Open the door of the machine, take an empty cup and put it on the electronic scale to clear it, then
place it on the grinder outlet and click "Start testing" again.
Weigh the coffee powder, enter the number of grams in the touch screen under "Discharge" and
"Save".
Put the empty cup on the electronic scale, then clear to zero and put it on the grinder outlet, then do the
"Start testing" again, weigh the powder dropped, compare the weight value with the value at the
"Discharge", if the deviation is within ±0.3 grams per second, it is considered Normal, if the deviation is
too large, recalibrate according to the above method until the value is OK.

15
6.3 Instant Canister Calibration
Canisters calibration is a program of measuring the dispensing speed of instant canisters with specific
powder. Before calibration, you need to prepare an electronic scale and cups and the calibration method is
same as grinder calibration above.
Important :
Lack of Calibration will cause a dispensing malfunction!
Before calibration, click [start test] to fill the canister outlet, a non-full outlet will lead to inaccurate
calibration.
Note :
Because every part or powder has different physical characteristics, so every time after replacing
canisters, motors or powder, you need to do calibration. Before calibration, make sure at least 1/3 of the
canister is full of powder
Use the key to open machine door. Long press the upper left corner of the screen, enter password in the
pop-up dialog box, administrator password: jn9527 or maintenance password: 9527. Enter the machine
background "coffee machine" interface.

powder poured into the canister, click [Save].
Remove the mixer under the canister, prepare an empty cup and an electronic scale, and put the cup
on the electronic scale to clear the zero (tare). Place the cup under the canister outlet.
Status Tab- Canisters Management –CAL, find the milk powder, click the calibration icon ; enter
Discharging Time (1-10 seconds, usually 2-3 seconds) in the pop-up dialog box, click "Start Test", the
machine will automatically dispense powder, once dispensing is over, place the cup with powder inside
onto on the electronic scale to clear the zero and place the cup under the canister outlet, click "Start
Test" again, once dispensing is finished, use the electronic scale to weigh again; enter the value of
gram into the "Dispense" blank on touch screen, and then "Save".
Put an empty cup on the electronic scale, clear the zero and then place the cup under the canister
outlet, then do the "start test" again, weigh the powder dropped and compare the weight value with the
value at the "discharge" on machine screen, if the deviation is within ±0.3 grams per second, it is
considered normal. If the deviation is too large, recalibrate according to above method until the value is
OK.
Repeat above steps on the rest 2 canisters.
