Falsely blocked heads.
It is the blockage of the head caused by the drying of the surface ink when the head of the printer is exposed to the air for more than half an hour. Soak the print head with the print head-clearing agent for 3-10 minutes — put pure water or warm water within 65 degrees in the ultrasonic cleaner — immerse the print head in warm water, turn on the ultrasonic cleaning for about 3 minutes – turn the printing Press the head on the high-grade facial tissue to see the prints, and confirm that the prints are clear and complete after pressing even 10 times – connect the hard board rubber-bottomed ink filling head to the residual ink head of the “vacuum ink filling machine” — put the hard board glue The bottom ink filling head is aligned with the printing head, the “vacuum ink filling machine” is turned on, and the printing head is pumped through the suction force of the vacuum.
Commonly blocked heads.
That is, the print head is exposed to the air for more than 10 days, or the ink cartridge has been added with inferior ink for a short time. After operating according to the clearing procedure of the fake blocked head, if the print head is still not clear, you can enter the clearing procedure of the general blocked head. Then immerse the print head in the clearing agent for about 30 minutes — immerse the print head in pure water or warm boiled water in the ultrasonic wave, turn on the ultrasonic cleaning for about 3 minutes — press the high-grade facial tissue with the print head to see the imprint, confirm by pressing 10 consecutively The lower imprints are clear and complete — use the vacuum suction of the “vacuum ink machine” to draw the print head through.
The uv flatbed printer stubbornly blocks the head.
That is, the print head is exposed to the air for more than 30 days, or the ink cartridge is added with new ink without removing the residual ink, a chemical reaction occurs between the old and new ink, or the poor ink is added for too long, resulting in blockage. After operating according to the cleaning procedure of general plugging, if the print head still does not pass through, it should enter the stubborn cleaning procedure. Add about 130ml of tap water to the “print head quick clearing machine” — align the clearing head with the print head, press it with a little force — turn on the “print head quick clearing machine”, use the Immerse the print head with hot distilled water, and at the same time use the pressure generated in the machine to clear the blockage out of the print head (usually this operation can be done for two or three minutes) – use the vacuum suction generated by the “vacuum ink filler” to pump the print head Pass.
At this point, no matter what kind of blocked head, it can be cleared.
