How to Troubleshoot Handheld Inkjet Printer Issues?

Although the failure rate of the handheld inkjet printer is extremely low, in the daily use of handheld inkjet printer have encountered some problems. Generally speaking, the working principle of handheld inkjet printers is relatively simple, as long as the operator master the common handling methods, most fault can be resolved easily, and we will explain it to you below.

  1. Check whether the encoder climbing ring is loose or off, if so, re-hang the climbing ring.
  2. Check if the ink cartridge has ink, if it is gone, replace it with a new one.
  3. Confirm whether there is data, you can reload the data.
  4. Reinsert the cartridge.
  • When the handwriting is blurred or the needle is leaking (intermittent horizontal lines), handle it carefully, especially when there are impurities on the surface of the nozzle, please wipe it gently with tissue paper. Please follow the steps below to complete.
  1. Check if there is any impurities on the nozzle surface. If there is, wipe it gently with a tissue.
  2. Shake the cartridge. (Please wipe the ink with a tissue)
  3. Dry the nozzle, drop a small amount of cleaning solution in front of the nozzle, and repeat step 2 above after 5 minutes.
  4. If the above operation fails, please replace the cartridge.
  • If the nozzle of the handheld inkjet printer has problem.
    • Nozzle is mainly composed of ink tube, recovery tube, cleaning tube, return line, nozzle, high pressure deflection plate, recovery box, discriminator, charging box, etc. At the same time, this problem is also very simple, the number of times to solve the problem is three electronic tubes in the ink circuit. The ink of our inkjet printer is easy to dry and condense in about 0.3 seconds. If it is not used for a long time, it may be a non-conventional shutdown, very simple. Ink builds up in the circuit and nozzles, which then causes the circuit to clog. When you encounter this type of problem, you must carefully determine which tube it is, and then train the user with the simple knowledge of the engineer to gradually repair and open the nozzle blockage is serious. You can use ultrasonic cleaning agent to achieve rapid processing.
  • If the code and typing is not clear or typing scattered.
    • In addition to cleaning the printhead and cleaning the print head before the filter, we should also learn to diagnose and test from the circuit part to avoid unclear typing, ink scattering, incorrect ink lines and other problems caused by circuit charging or calibration problems. Stability and other problems. The detailed circuit part includes charging calibration, pressure calibration, high voltage measurement, ground detection and other measurements. At this point, we need a multimeter to assist in the work. The use and operation of the multimeter is also essential. Printer repair master to gradually understand the circuit knowledge part is to gradually solve the problem of circuit ink, which is a faster and more stable way to solve the problem.

These are the common troubleshoots and the corresponding solutions of handheld inkjet printer, we hope it will help you. And if you still want to consult more information about handheld inkjet printer, welcome to contact with our specialists.
