Frequently Asked Questions of LT1000 Series (One)

Question: How to call for technical support?

Answer: Observe the real phenomenon of the malfunction of machine, and adjust the corresponding parameter; record the operating condition of the machine and the parameters on the Diagnostics Screen in detail, and call for help from Lead Tech headquarters or offices in the corresponding area.


Question: After I turn on the power, the panel of the machine is not bright or very dark. I cannot see the characters clearly. How to deal with it?

Answer:

1)The power source has no voltage. Check the power source.

2)The setting of the brightness of screen background is not correct. Press CTRL+L to adjust the brightness.

 

Question: After the machine is turned on normally, it appears the alarm of Charge Error frequently.

Answer:

1)The charge electrode or the phase detector is dirty or wet. Flush the nozzle, the charge electrode and the phase detector. Dry the printhead.

2)The breakup of droplets is bad. Observe the position of the ink stream. If it is necessary, adjust the parameter.

3)Poor grounding. Check whether the grounding wire is in good contact.

4)The ink system is dirty or there is something wrong with the ink/top-up. Please contact engineers of Lead Tech.

 

Question: There is no fault warning, but it does not print.

Answer:

1)The setting of Width or Product Delay in Message Parameters is wrong. Adjust Width or Product Delay.

2)Malfunction of photocell. Check the connection of photocell, and clean the inductive head of photocell.

3)The installation position of photocell has changed. Install and fix photocell all over again.

4)The setting of sensitivity of photocell is not correct. Adjust the sensitivity of photocell.

 

Question: When the machine is turned on normally, it appears the alarm of EHT trip.

Answer:

1)The printhead is dirty. The ink stream is deflected. Flush the nozzle and make it clean and dry.

2)The mains power supply is bad or the grounding is poor. Check the power supply and make sure that the machine is well-grounded.

 

Question: When in the printing process, sometimes the products miss printing.

Answer:

1)The photocell has not been installed well. Change the installation position of the photocell, and make sure that in the continuous product movement, every product can be sensed by the photocell; Exclude the influence of color to the photocell.

2)The sensitivity of photocell has not been adjusted well. Adjust the potentiometer of the sensitivity of photocell. The right adjustment is that when the photocell has an inductive signal, the corresponding sensor light is on.

 

Question: When in the process of starting jet, the position of ink stream is not correct or the ink stream is not stable.

Answer:

1)Nozzle clogging. Flush the nozzle. Because the inkjet printer uses quick drying ink, if the machine is not cleaned well when it stops jet, or the machine has not been used for several days, it is easy to cause nozzle clogging.

Make sure that you start jet and stop jet normally. If the machine is going to stop using for a period of time, make sure the machine will be in normal operation for over 2 hours every 10 days or so.

2)Filter clogging. Please contact engineers of Lead Tech for regular maintenance.

3)The ink stream of nozzle has not been adjusted well. Adjust the nozzle under the guidance of engineers of Lead Tech.
