UV flatbed printer problems and solutions

1, UV light goes out during printing.

Failure analysis:too low supply voltage or UV lamp out of lifespan.

Solution: If the UV lamp has been used of a long time, remove the UV lamp tube to check the two if the two ends becomes black. If yes,  replace the UV lamp;  if the lamp is not used for a long time,  use mutimeter to check if the voltage is low. If yes, add regulator and check again.

2, The printer carriage can go right, but can not go left.

Failure Analysis: The printer can not read the raster.

Solution: Detect whether the grating is in the middle of the grating sensor and detect if the grating sensor is abnormal.

3, The print head current temperature displays abnormalities and no temperature when it is   touched by hand.

Failure Analysis: Check if the print head temperature line is abnormal.

Solution: reorganize the corresponding print head cable or replace the print head plate.

4, The machine suddenly stop printing when it is in normal power supply.

Fault Analysis: USB transmission signal is interrupted.

Solution: first check if the USB cable contact is not good and re-plug the USB cable; if the problem is not solved, you can directly change USB cable. And finally check whether the static is too much.

5, The printer carriage keeps shaking on X-axis when printing.

Failure analysis: X-axis movement resistance, or X-axis servo motor horsepower is insufficient.

Solution: first turn off the machine and move the carriage by hand back and forth to check if the moving is smoothly, if not smooth, clean the X-axis guide chain and

add lubricating oil; If smooth, increase horsepower of the servo motor .

6, Inks printed on the material can be easily scraped.

Failure analysis: UV lamp poor curing effect.

Solution: Use alcohol to wipe the UV lamp quartz glass to make it better light transmission, and check the UV light lifespan.

7, The machine starts normal, but UV light can not open up.

Failure analysis: UV lamp no power supply.

Solution: Check the UV lamp switch, relay and power supply.

8, Ink often goes back to the safety bottle.

Failure analysis: too high negative pressure

Solution: re-adjust the negative pressure and then look whether the ink still return, if not

problem has been resolved; If yes, you can directly replace the negative pressure table.

9, 1PASS error often occurs in the printing .

Failure Analysis: Data error.

Solution; first re-make the printing picture. If unresolved, re-install the computer system and print software.

10, The print software shows no connection to the printer.

Failure Analysis: The computer is not connected to the printer.

Solution: Check if the USB cable between the printer and the computer is connected and the printer driver is installed. Replace the USB cable and check the computer USB interface and printer USB interface.

11, When the machine starts, X-axis reset is not normal.

Failure analysis: X axis limit signal is abnormal.

Solution: check if the X axis limit and limit sensor line is loose and further check if the sensor is damaged, Finally, check the X-axis servo signal.

12, When the machine satrts, Y axis reset is not normal.

Failure analysis: Y axis limit signal is abnormal.

Solution: check if the Y axis limit and limit sensor line is loose and further check if the sensor is damaged.
