1. What’s the matter with the flashing of the UV light of the flatbed printer
The UV light is one of the core components of the UV printer. Its main function is to ensure the adhesion of the UV ink. The surface of the pattern can be dried quickly and thoroughly to avoid the phenomenon of fading and falling off of the pattern. When using the uv printer, sometimes the uv light flashes, which affects the printing effect. Then the uv light of the uv printer flickers It is how it happened?
1. Unstable voltage: check the voltage of the uv printer and set up a voltage stabilizer box.
2. The temperature is too high: the high temperature of the uv printer will also affect the uv lamp, and it can be replaced with a water-cooled circulating cooling.
3. The signal wires in the water tank are in poor contact: Swap the signal wires on both sides to make sure they are in good contact, then plug them back in and fix them.
4. UV lamp failure: check the uv lamp, repair or replace the new uv lamp.
Second, common faults and maintenance methods of uv lamps of uv printers
uv flatbed printers use uv ink and uv lamps to achieve printing, due to different The wavelength curing of the ink under ultraviolet light is different, so it needs to match a special uv lamp. If it is used for a long time or is used improperly, it may lead to failure. The common failures are:
1. The uv light does not light up
(1) The uv power cord is damaged, replace it with a new uv power cord.
(2) If the UV light strip is damaged, replace it with a new one.
(3) If the internal power supply of the water tank is damaged, repair the damaged part of the internal power supply. If it cannot be repaired, contact the manufacturer to replace it with a new one.
(4) The upper knob of the water tank is 0 power output, and the lower knob is adjusted to output power.
(5) The light of the control software is not turned on, just turn on the light of the control software.
(6) If the lamp is damaged, contact the manufacturer and replace it with a new uv lamp.
(7) If the board is faulty, contact the manufacturer and replace it with a new board.
2. The uv light does not go out
(1) The Y-board relay is aging, just replace the new Y-board relay.
(2) The software does not turn off the test uv lamp, just turn off the software for testing.
(3) The uv control line is short-circuited, replace the control line and reconnect.
(4) If the board is faulty, replace it with a new board.
3. The uv light is dimmed
(1) Check whether the knob on the water tank has changed, and twist the knob on the water tank to solve the problem.
(2) Open the water tank, check whether the power supply inside the water tank is damaged, and which power line is short-circuited and burned, reconnect and repair it.
(3) The power cord is damaged and needs to be replaced with a new uv lamp power cord.
(4) If the uv light strip is damaged, replace it with a new one.
(5) If the contact is poor, if the interface is loose, it can be tightened again.
(6) If the temperature is too high, check the refrigerant in the lower water tank and add new refrigerant.
4. The uv light illumination distance is wrong
(1) The uv light power cord is reversely connected, and the uv light power cord of the uv printer can be connected upright .
(2) There is a problem with the lighting distance, adjust the lighting on the software.
