1. Test the printer: test the mechanical properties and lubrication of the printer
a. Check the nozzle; take a piece of A4 paper and print the nozzle test line to see if the nozzle is normal. If it is abnormal, please perform 2 ~ 3 times of cleaning, and then check again.
Operation: Start → Settings → Printer or Fax Machine → Right-click the printer to be tested → Printing Preferences → Maintenance → Nozzle Check
b. When the nozzle is normal, select a colorful picture and print with special printing paper → photo settings to check the printing effect.
Fine horizontal stripes → nozzle check → normal → print head quality is reduced
Small horizontal stripes → nozzle inspection → abnormal → cleaning after normal measurement
Second, even for installation:
a. According to the product manual, check whether the continuous supply accessories are complete
b. Check whether the continuous supply is leaking ink, whether the pipeline joint is damaged or falling off
c. Read the installation instructions carefully before installation
d. After installation, carefully check the length of the pipeline, move the carriage to the left and right, and check whether the pipeline is in the best position (the printer should be powered off when moving the carriage)
The pipeline is too long, and the printer will make a noise during the printing process.
The pipeline is too short, and an error will be reported during printer operation.
e. Check whether the small vent hole of the external ink cartridge is open (after opening, replace the filter to prevent air dust from falling into the ink)
I forgot to open the small vent hole → The ink of the external ink cartridge cannot be supplied to the built-in box → The negative pressure is inside the print head → The printing is very fuzzy or the printing is blank
g. Make sure that the external ink cartridge is at the same level as the printer and cannot be too high or too low. External ink cartridges cannot be lifted or moved during use
The external ink cartridge is too high → the pressure of the external ink cartridge is greater than the pressure of the internal ink cartridge → the external ink cartridge-the pressure of the ink toward the internal ink cartridge
External ink cartridge is too low → Insufficient ink supply → Print color is lighter
