Do You Know Which Nozzle is Best for The UV Printer And How to Install It?

  UV printing is a new technology in the digital inkjet printing industry. Widely use for advertisement printing like outdoor advertisement printing and indoor advertisement printing. Same as the sublimation printing, the print head is also a very important accessory for the UV printer. While do you know what print head is suited for the UV printer? And in order to let it have a best printing effect how to install it in a right way? I will share you in the following articles. Keep reading and know more.

Konica nozzle
  Konica nozzle, a recently introduced Japanese brand whose first image-based company was involved in the production of piezoelectric sprinklers, has also been successful at hardware facilities, including the Konica Minolta 512 sprinkler and 256 sprinklers.

Polaris nozzle
  The American Polaris Spray Head is a hyperspectral PQ-512/15 with a wide range of portrayed utility inkjet print heads for industrial and commercial print scale resolutions up to 1000 dpi.

Ricoh nozzle
  Ricoh acquired Hitachi's nozzle technology research and development department, Hitachi had two nozzles used well, HITACHI 256 I and HITACHI 256 II, VUTEK5300 and VUTEK3300, these two machines each use 16 HITACHI 256 I nozzles, HITACHI 256 II This nozzle is mainly used in the HP Scitex: Idanit, Pressjet machines, HP scitex Pressjet and HP tuberjet 83 used 150 HITACHI 256 II nozzle, the record seems to have not been broken by now.

  These all above are three print head that most suitable for the UV printing I suggest you. After the introduction of the print head, next I will share you how to install the UV print head in a right way.
  1. To prevent nozzle clogging, you are strongly advised to install print head in a clean environment.
  2. To avoid electrostatic damage to the nozzle clip, please install print heads in an environment with static protection.
  3. To avoid damaging the nozzle face, do not impact or directly touch with the nozzle face by hand.
  4. Protect the print head cable from scratching or cutting off by external forces.
  5. To ensure print accuracy, control the flatness of the nozzle mounting surface within 10 microns.
  6. When installing UV print head, the positioning bolt must be fully embedded in the installation hole to prevent print head tilt installation. 
  7. In order to avoid excessive external force applied to the nozzle, please control torque at about 0.63n nanometer when fixing the print head.
  8. To avoid damage to the ink supply port, do not apply force when installing or removing the ink supply hose.
  9. Don’t live insertion or pull out of print head cable, and pay attention that print cable don’t not diagonal insert, in order to avoid nozzle damage caused by bad contact.

  Okay, These all above are my share about the print head that most suitable for the UV printer and some ways about how to install them in a right way. If you have any other needs or questions welcome to contact us at any time. We will provide you with the best quality product and service. Hope my article can be useful to you. Thank you for your reading.

Ways for You to Solve The Problem If The Print Head of Your UV Printer is Blocked

  Hi, Nice to see you. In the digital inkjet printing process, whatever your digital printer is the sublimation printer or the UV printer. You all should grasp some basic ways to solve the problem if your print head is blocked. While in my last articles I have shared you about howto solve it with the sublimation print head and today I will help you about how to solve when it happen in the UV printers.
   Firstly, for the print head of the UV printer. The blocked can be divided into different levels. So in order to have detailed introduction I will share you from the different levels.

Level 1 Lightly Block
Solution: Soaking
Specific Method
  95% alcohol, a clean cup and a flat bottom metal containers. Prepare a small plate, put the nozzle on the it, and then into the disk some UV printer cleaning fluid, the depth of the fluid just above the nozzle. Be careful not to spill liquid on the cable plug and drive circuit board, the first soaking time of 1 to 4 hours.
Level 2 Heavily Block
Solution: Nozzle Injection Pressure Washing
Specific Method
  95% alcohol, a clean cup, a disposable syringe, disposable infusion set. Working principle: use syringes siphon effect of the pressure, put the cleaning fluid into the print head, so as to achieve the purpose of cleaning blocked print head.With a plastic tube of the infusion set, one side plug in the syringe, the other end put on the nozzle that need to be clean. Press the clean liquid from syringe to print head, pay attention to the pressure , should not be too strong, make sure not to squeeze the inside waterproofing glue.This process needs to be repeated several times until you see that each ink hole ejects a slim water column. In this way, the blocked nozzles are cleaned.

Level 3 Heavily Block
Solution: Distilled Water Cleaning
Specific Method
   A coded empty cartridge, a disposable syringe and a bottle of medical distilled water (also available with pure water), similar to the nozzle injection pressure washing.
  Prepare a decoded empty cartridge, a disposable syringe and a bottle of medical distilled water, use siphon action of the syringe pressure, inject the distilled water through the cartridge hole, after a while sucked out the distilled water by the syringe , few times the ink cartridge can be cleaned.

Level 4 The Most Serious Block
Solution: Ultrasonic Instrument Cleaning Method
Specific Method
  Gently put the print head into the washing machine, add pure water or special cleaning liquid, just cover the print head stainless steel edge (Be careful not to let the PCB board splash with pure water or special cleaning solution),10 to 15 hours can be quickly cleaned. The advantage is that the cleaning effect is very good, even for year blocking print head can be cleaned, the operation is also very simple. The disadvantage is that the cleaner maintenance costs is higher and the price is expensive.

  Okay, These all above are my share about how to solve the block of your UV print head. If you have any needs or questions welcome to contact us at any time. We will provide you with the best quality product and service. Hope my article can be useful to you. Thank you for your reading.
