FAQ (Frequently Asked Questions)

●Inspection and Removing of Common Faults

Cleaning the print heads during the course of working:

1. During the course of work processing , if you found some print head blocked, please hit the pause button, Ink carriage will be automatically moved to the Left washing area of the machine

2．By washing key to positive pressure washing. Then please clean off the surplus ink with the wipe cloth.

3. Cleaning is completed, press the restore button, then you have completed the cleaning task and please continue to printing.

4． You also can use the high quality industrial cleaning cloth, lightly dipped in cleaning fluid to attach the below nozzle face,
Repeat several times to remove the plugged nozzle.

5.If invalid (nozzle blocked seriously), you need to clean the print heads with cleaning solution, for details , see print heads cleaning part.

8. If the above positive pressure, cleaning operations are invalid (to mean that the print heads is blocked very seriously), you will need to stop printing, turn off power, remove the nozzle, and then down into the nozzle with the dry cleaning fluid, the Net glass containers or other ceramic containers, cleaning fluid level should be just drown the heads nozzle, that is suitable, soak for 8-24 hours, then take it out and make it re-installed;

When take down the print heads, you must be more careful. Don’t scratch the head surface! Don’t take the head top meet the cleaning solution at all. At the time of installation, you need to re-adjust heads spacing.

9．All of the above operation is of no effect, please contact with the dealer to request professional care or replace another new one.
Please note the ink tube sealing of docking the print heads.

10. when finishes every printing task, the carriage should be returned to the original position, that is means back to the top of the machine ink pad for the purpose of protecting the print head from broking off. Please check the print heads at the beginning of every printing task to ensure the print heads condition correct.

Does the printer need to be carried out maintenance after its end of work ?

After every day off work make sure of carrying out maintenance on the print heads , to prevent heads from blockage.

1. Please put some pieces of special machine-specific wipe paper into the protection tray to reserve.

2. Please pour appropriate amount of cleaning liquid into the tray. (the longer down time, the more cleaning solution you should pour, in order to ensure the wipe paper wet as the beginning of the printer re-boot)

3. Please put the tray down to the holder, and move the carriage onto the printing platform.

How to make a maintenance for machine if non-use it for a long time?

If the machine is not used for a long time, ink and the nozzle should be kept clean. Because the ink is oily, and may be into precipitate so that jammed the ink pathway and the print head.

1，All the colors pathway should be taken out from the ink bucket.

2， Press off the ink in the air pipe and in the dipolar cartridge.

3，Insert all the ink tube into the cleaning solution.

4，Please clean the ink pathway and the print heads with the cleaning solution until the clear cleaning solution flown down from the print head.

Repeat the steps of daily print heads maintenance.

6, For the carriage, please use the plastic wrap to seal. (To prevent cleaning liquid excessively volatile.

How to wash the print heads?

1， Unscrew the connector between the print heads and the dipolar cartridge.

2， Please connect the cleaning tube to the print heads.

3，Open the left side of cleaning switch to washing the print nozzle

 Note: Do not take consecutive time to clean the nozzle, it is necessary to release the switch once every half a minute , to prevent excessive pressure from causing nozzle damage.

Large format digital printer maintenance:

1． Keep the operation work field clean and tidy.

2． Keep Transmission belt properly tensioning. Open the left cover can adjust the synchronization belt tension of the drivers carriage. After adjustment, the connecting screws must be tightened

3． The areas surrounding the print heads and print hole must be kept clean and pureness, can not be accumulation of residual ink, or contaminated dust,
Fiber, can not scratch nozzle plane

4． Ink and cleaning fluid all contain strong solvents, must not contact with electrical components and wires, floor cover. If shell or other areas is accidentally spilled by ink or cleaning liquid, please wipe clean as soon as possible

5． Please keep the work surface clean, check the countertop without screws and other foreign matter before boot, so as not to scratch the nozzle.
                  

Common failure causes and solutions:

1. After boot-strap the jet-car are not back to the origin point.

When starting the machine working, at first the client should detect the the state of origin sensor is low, they will work to issue the direction and Y pulse motor commands to the Y motor drive. Y motor rotation to spray car returned to its original position. Detection may be in power situations, to see whether the lights on the motherboard D3 is bright or not. If not, the mother may be some problems. Then turn off the left origin, to see whether the lights on the motherboard (D5 D6) bright or not , and that way you can confirm the origin signals is normal or not, if it is all regular, the drive and motor should be to find the problems.

2. Display the gray status, which can not be operational when Open the software.
   

   1) USB driver is not installed.
      2) When limit switch signal for the disconnected state, the board can not enter on-line state.
3) Motherboard damage.
      4) USB faulty connections.
5) Computer motherboards and driver take an error.

3. No ink supply from the print heads

Case 1: There is no flash spray at the origin. Normally the machine will flash back to spray the work in situ. There are three necessary conditions for the in situ signal is correct, flash jet signal, and the heads drive voltage. Please confirm these working conditions normal.

Case 2: when stop at the origin there is flashing jet, but not ink-jet as printing. This is because there is no feedback signal caused by motherboard. In the process of System working, the beam raster controls the jet signal, through the head board, trough the 18 P line connecting to the I/O board, and then to the mother board. Please Check the raster to be sure it has no wear, decoder, and to check the 18 P lines are able to return the correct grating signal or not.

4.Exceed ink supply without end. Exceed ink sup exceed ink supply

If there is appearance that all the color is supplied ink without end, please check the 18P line, I/O board.
   

 If only one color is supplied without end, please check the I/O board.

5.No ink
  

  First of all, we need to see if there is ink enters into the air bottle, and the interface board should stop supplying ink at this moment. Second. Check float-switch position, 18P long-term data and interface board. Float switch off &on responses the state of the ink in the vice ink-bottle. This signal returned to the interface board by the long-term control chip. The interface board controls the pumps in turn for supplying ink for some time, if not find out the status of lack of ink in the regulation time, you need to stop supplying ink, and be sure to issue a warning prompting.

6. Print head with ink drop out.

For the first reason, it uses the siphon principle while the system ie progress in ink supplying , that is usually liquid, Vice ink bottle through the air bottles, air pipes, solenoid valves and then connecting with air. When any one jam session, you conducted for the ink, the air in the vice ink bottle will be no way to blow off, By the end of the high Pressure, it can press the ink out. Another phenomenon of this failure, it maybe occurs that the ink breaks off after a period of printing. Secondly, the ink pump stops supplying ink, as a result of the excessive high pressure in the air bottle.
