5First operation
5.1 Filling the bean hopper and canisters
Use the key to open the machine door.
Put on a mask and disposable edible gloves.
Turn the powder outlet of the canister upward and remove the canister.
Open the top cover of the canister and add the powder to the canister accordingly; click on the
screen and enter the weight of the added material in the pop-up dialog box【Fill】.
Place the canister back into the machine, rotate the canister layout to facing the middle of the
mixer.
Note:
When the machine is filled with powder for the first time or after cleaning the canister, you need to
click 【Recipe】select 【Mocha】【Start cooking】to make a drink and then discard it,
the purpose is to ensure that the canister outlet is filled and the drink is dispensed according to
the recipe dosage.
Only timely replenishment of powder, the machine can operate normally.
6Commissioning and calibration
6.1 grinder coarse and fine adjustment method
To adjust the coarseness and fineness of the grinder according to the
silkscreen layout.
Without beans, as a benchmark coarseness position (general espresso
coarseness), first screw the knob clockwise to the position of the disc fit
(normal torque until it cannot be screwed), and then rotate the knob
counterclockwise 16 turns, later in the calibration process according to
the coarseness of the powder and then fine-tuning (clockwise direction
is to adjust fine, counterclockwise is to adjust coarse).
6.2 Grinder Calibration
Calibration is a software done for instant cartridges, physical properties of powders, coffee
bean roasting, etc. Before calibration you need to prepare the electronic scale and cups.
Important:
Failure to calibrate will result in abnormal machine output!
Make sure that the canister outlet is filled before calibration, which can be achieved by the
"powder drop test" function, if the outlet is not full, it will lead to inaccurate calibration.

14
Note:
Because of the density of coffee beans, blending, roasting, bean pressure, the structure of the
grinder and other factors, so each time when replace the bean box, grinder, different brands of
coffee beans, you need to recalibrate. When calibrate the coffee beans, the bean box should be
greater than 500 grams of coffee beans.
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. Then enter the machine
background "coffee machine" interface.
In the Status - Canisters Management - Fill, select the coffee bean box, click , in the pop-up
dialog box [filling] enter the weight of the coffee beans poured into the coffee bean box, click
[save]. Each time you add coffee beans, you need to enter the weight of the additional beans.
in Status - Canisters Management - CAL., Find the coffee bean column, click on the calibration
icon ; in the pop-up dialog box "Dispense Time" (range is 1-10 seconds, generally input 2-3
seconds), click "Start Test" 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 the
zero, then place it on the grinder outlet and click "Start Test" again.
Weigh the resulting coffee powder, enter the number of grams in the touch screen at the
"Discharge" and "Save".
Put the empty cup on the electronic scale to clear the zero and put it on the grinder outlet, then
do the "Start Test" 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. Once
the calibration is complete, there is no need to recalibrate if the same brand of coffee beans is
added again.
6.3 Instant cartridge calibration
Canisters calibration is a software done for the physical properties of the instant canisters and
the physical properties of the powder. Before calibration, you need to prepare the electronic scale
and cups, and the calibration method is the same as the grinder calibration above.

15
Important:
Failure to calibrate will cause the machine to dispense abnormal powder!
Make sure that the canister outlet is filled before calibration, which can be achieved by the
"powder drop test" function, the outlet is not full and will lead to inaccurate calibration.。
Note:
Because each part or powder has different physical properties, each time the canister, motor or
powder is replaced, it needs to be recalibrated with the amount of powder in the canister greater
than 1/3 of the canister volume at the time of calibration.
Use the key to open the machine door; Press and hold the upper left corner of the screen, enter the
password in the pop-up dialog box, administrator password: jn9527 or maintenance password:
9527. Then enter the machine background "coffee machine" interface.
In the Status - Canisters Management - fill, click , in the pop-up dialog box [Fill] enter the
weight of milk powder poured into the canister, click [Save]. The weight of the coffee beans to
be added each time the powder is added.
Remove the mixer under the canister, prepare the cup and electronic scale, and put the cup on
the electronic scale to clear the zero (tare). Place the cup under the canister outlet.
In the Status - Canisters Management –CAL. Find the milk powder column, click the calibration
icon ; in the pop-up dialog box "Discharge Time" (range is 1-10 seconds, usually 2-3 seconds),
click "Start Test", The machine will automatically dispense the powder, confirm that the powder
is finished, pour the powder back to the raw material box, put the cup on the electronic scale to
clear the zero and put it back to the bottom of the material box outlet, click "Start Test" again,
confirm that the powder is finished, then use the electronic scale to weigh; in the touch screen,
"Dispense", enter the number of grams, and then "Save".
Put the empty cup on the electronic scale to clear the zero and then place the powder box
outlet, then do the "start test" again, weigh the fallen powder and 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.
The remaining two boxes filled with powder weight and calibration methods are the same as
the milk powder.

16
6.4 Recipe Management and Testing
Press the upper left corner of the screen, in the pop-up dialog box, enter the password: jn9527; click
[recipe], in the pop-up recipe management interface, select the corresponding product, in the
pop-up recipe parameters interface, you can adjust the product water, material quantity, mixer
speed, delay time, modified [save], click [start cooking] to make drinks.
Recipe management can customize recipe, add recipe, delete recipe, start cooking, save recipe, save
product, import recipe, export recipe, and recipe editing function. Editing of the corresponding
functions can be implemented in the corresponding modules.
Note:
By analogy, the calibration method for sugar and cocoa is the same as that for milk
powder, which needs to be calibrated according to the above method; recalibration is required
when the machine is new or when updating the canisters, motor or different brands of raw
materials; recalibration is not required when replenishing the canisters.
