Fault description and handling method of Afes A series
1.Do not print:
1. Electric eye:
A. Check whether the electric eye is on, if it is not on, replace it with a new electric eye to test
B. On, whether the counter is counting normally, if not counting, maybe the synchronizer function in the parameter is turned on and off, that’s all.
C. The electric eye is always on, check whether the electric eye shines on other things, or adjust the sensitivity to a lower level.
2. Ink cartridge: (the upper left corner of the machine display shows that the ink cartridge is empty)
A. The ink cartridge is out of ink, replace the ink cartridge.
B. The flowmeter alarms, replace the flowmeter.
C. The nozzle is higher (or lower) than the ink cartridge, readjust the balance and keep the same level.
3. Hardware problem:
After the above 2 problems are eliminated, if it still cannot print normally, you can consider the hardware part
A. Whether the cable connected to the main board is loose or falls off, just connect it.
B. Whether the cable connected to the main board is loose or falls off, just connect it.
C. Main board failure, return to factory for repair.
D. If the wiring in the nozzle box is loose or falls off, just reconnect it.
E. The small control board that controls the nozzle in the nozzle box fails or burns out, just replace the small control board.
F. Nozzle clogging: Use matching lotion and cleaning tools to clean the ink path. See the actual operation and cleaning process for the cleaning method.
G. If the nozzle is damaged or the film is removed, only a new nozzle can be replaced.
H. Squeeze the ink, but the ink does not come out of the nozzle: 1. The needle of the ink picker is deflected or broken, resulting in abnormal ink intake. Correct or replace the ink picker.
D. The nozzle is clogged, resulting in no ink supply, clean the nozzle, or the ink path.
2. Print only half:
1. Cartridge:
A. The ink is not squeezed in place, and there is air in the middle. When the ink is squeezed, there are air bubbles in front of the nozzle. Squeeze the ink again, remove the air, and squeeze until the air bubbles are no longer visible.
B. The nozzle is higher (lower) than the ink cartridge, adjust the balance and keep the same level.
2. Hardware part:
A. The nozzle is partially blocked
B. The nozzle is bumped or scratched
C. Whether there is dust or paper fragments sticking to the spray hole, which blocks the spray hole and cannot work normally.
3. Blurred printing:
1. If the distance is too far, the distance between the nozzle and the product plane should be controlled within 1cm for the best effect.
2. The nozzle is blocked
3. There is no ink in the ink cartridge, or the ink is insufficient. It is recommended to replace the ink cartridge with a new one.
4. Daily maintenance:
1. Every 5-7 days, print a 18mm character height, solid large characters, let 128 nozzles work normally, until the printing effect is no disconnection, depending on the normal operation of the nozzle.
2. Every 2-4 days, use the matching lotion to spray the surface of the nozzle, wash off the dust and paper sticking on the nozzle hole to prevent the nozzle from being blocked, and then squeeze some ink.
5. Precautions:
1. The power supply system of the machine must be stable, 220v+(-)10v
2. The grounding is good. The machine and the packaging line must be connected separately to a ground wire to prevent excessive static electricity from burning out the main components of the inkjet printer, such as the nozzle, main board, and display.
3. The machine needs to be managed by a special person to avoid problems that no one will connect and maintain, which will cause the factory and equipment to not be used normally.
6. Cleaning process:
1. Pull out the ink cartridge with ink and insert the empty cleaning cartridge
2. Use the syringe to discharge the residual ink in the ink tube at a constant speed
3. Pour the matching cleaning agent into the syringe, push the cleaning liquid out of the syringe at a uniform speed, and let the cleaning liquid shoot out from the front of the nozzle
4. Observe whether the injected cleaning liquid is in a straight line state, if so, just drain it, if not, repeat the 3 steps for several times
Ground wire requirements:
1. Live wire and neutral wire: 220v+(—)10v
2. Fire wire and ground wire: 220v+(—)10v
3. Ground wire and neutral wire: 5vPlease be strict with the above grounding standards, otherwise static electricity will seriously affect the printing effect, and burn out some important components such as the nozzle and the main board
Precautions:
The inkjet printer should take insulation measures as far as possible, and do not touch the packaging line (because the voltage of the equipment on the packaging line is 380v, 220v, far exceeding the normal voltage of 40v used by the inkjet printer), if it works under this high voltage for a long time, it will Interfere with the normal work of the inkjet equipment, reduce the service life of the equipment, and seriously burn the nozzle, main board, and main components, and delay the normal work process of the factory.
