Instructions:
After receiving the product, remove the nozzle from the package. Before disassembling the protective device, shake the nozzle continuously to the left and right according to the figure to achieve the best use effect to achieve the best use effect. Then remove the protective device (orange with the outwardly turned handle). In order to avoid the internal inverted buckle of the protective device from damaging the circuit of the print head and causing the print head to fail to operate, pay attention to push the handle out as hard as possible. Then pull the reminder label together with the sealing blue tape to tear off. Finally, pull out the protective plug of the ink supply needle (the orange belt, please shake the nozzle arrow left and right before opening the protective clip).
Installation steps:First take out the two old print heads, close the cover and turn on the printer power normally. After the print head indicator on the machine flashes, open the cover. At this time, the print head carriage (carriage) in the machine will move to the left of the machine. After it stops, install the two nozzles one by one and close the machine cover. The machine will perform calibration and print a test page. Some models will prompt calibration failed or calibration failed (this is a technical obstacle set by the original company for its products to monopolize the market, but the chip has a memory function after all nozzles are regenerated, making the calibration fail , Has nothing to do with the quality of the regeneration nozzle). In such a situation, click the OK or Confirm button on the machine panel according to the prompts, and the printing will proceed normally.
Reminder: Some models will calibrate and print a test page every time they are turned on. This is normal and has nothing to do with the quality of the print head. Just click the 0k or confirm button on the machine
panel. It will not be calibrated every time you print without turning off the machine. Some models of the machine
will perform a longer calibration before and after the first printing, which lasts about 20 minutes. At this time, please do not turn off the machine
or press any control keys to avoid affecting the calibration.
Precautions:

components and damage.
(2) Check whether there is enough ink

at any time, and add it in time to avoid the lack of ink
to burn the nozzle.
(3) The machine
should not be left unused for too long
