White ink is printed abnormally, what can I do?

Issue examples：

  1. There is ink mist on printed samples and attached to the inner printer embrace
  2. No nozzles out on the Exam Print, nonetheless it starts having nozzles out later on normal printing
  3. The White colour density is reduced compared to the previous print results

Recovery Procedure

  1. Operate a Normal cleaning
  2. Operate a Difficult cleaning
  3. Set upwardly the "Waiting Refresh level" to "2" or "3"
    [SETUP]-[SELECT]-[TYPE1]-[REFLESH]-[WAITING]-[LEVEL 0～3]
  4. Set up the "Cartoon Refresh level" to "2" or "three".
    [SETUP]-[SELECT]-[TYPE1]-[REFLESH]-[Cartoon]-[LEVEL 0～3].
  5. Verify the printer environments (Temperature, Humidity, and Dust) are within the specifications.
    Specification of the Printer environment:
    Available temperature: [15～thirty℃ (59～86F)]
    Guaranteed temperature: [xviii～25℃ (64.iv～77F)]
    Temperature change: [±ten℃ or less]
    Grit: [Equivalent to normal office level:　Floating dust amount is less than 0.15mg/㎥]
    Humidity: [35～65%Rh (No condensation)]
    ・ These bug can happen peculiarly if the temperature is lower than the specification, because of the viscosity increases.
    ・ If the room has a high corporeality of grit, the dust attaches to the print caput surface. This will cause "Ink mist" or "Nozzles out" bug.
  6. Verify the ink storage temperature is within the Ink specification.
    Ink specification:
    Storage temperature: [fifteen～30℃ (59～86F)]
    Shipping temperature: [0～threescore℃　(32～140F)]
    ・The ink will be frozen if it is stored under -iv℃ (24.8F).
    If ink cartridge is stored under -4℃　(24.8F)　the ink volition be frozen.
    If the ink freezes, leave the frozen ink cartridge for over 3 hours to thaw at normal storage temperature. [fifteen～thirty℃ (59～86F)].
  7. Important Daily Maintenance is necessary.
    Refer to the "Daily Care Manual"
    Clean around the wiper, flushing box, and print head surface. Refer to the "Daily care transmission " or "Operation Manual " for details.

    Make clean the ionizer needle. Refer to the "Operation Manual ".
    The ionizer reduces the static electricity, however if the ionizer needle is muddied, it cannot effectively reduce static.

  8. Important　White Maintenance
    hite ink precipitates easily compared to the other colors. If information technology precipitates inside the ink line, you will run across the following issues.
    a. Nozzles out on the Exam pattern
    b. No nozzles out on the test pattern but start having nozzle out issue afterwards start normal print.
    c. Nozzle deflection
    d. White ink mist
    eastward. White ink density is lighter if it is compared to previous print issue.
    Once information technology is precipitated inside ink line, printer needs to be fixed past technician.
    ① One time a calendar week, operate a White Maintenance
    Refer to the "Operation manual "(Regular Maintenance of White ink)
    ② Earlier starting your job, remove the white cartridges from printer, shake them well, and reinsert information technology. So perform a Normal cleaning.

    How to milkshake
    Wear gloves and apply material to the insertion side as shown below pictures to avoid getting ink on your easily. Tilt the cartridge gently from side to side more than 20 times, so ink inside tin be circulated. If a cartridge is roughly tilted, the foil pack inside may be damaged. This may cause an ink leak. Please tilt the cartridge gently. When the level of ink remaining is depression, tilt the cartridge vertically, otherwise ink tin can non be fully circulated.

  9. Make sure media feeding amount is correct.
    Refer to the "Operation manual "Setting media bounty" for more information
  10. Set up the "Caput gap value" with the following steps.
    * "Caput gap" means the distance between the highest bespeak of impress surface and the inkjet impress caput surface. If the value is smaller, inkjet head can fire ink more straightly.

    Set the head gap value to 1.5mm

    This is the procedure to set the head gap value. Nevertheless sometimes the actual head gap is higher than the head gap you set. Run across the below examples for details.

    Caution 1
    If the print material has convex-concave print surface, the head gap between the convex-part (Highest) and head will exist the set value. However the actual gap between the concave-part and head will be the "Gear up value" + the "Pinnacle deviation between the convex-concave".

    The acme departure between the Convex-Concave (Highest – Lowest) has to be
    less than 2.0mm or less.
    ※Refer to "Precaution when printing in head gap more than 2.0mm" which you lot can notice in the UJF-706 Manual.
    If the height divergence is more than 2.0mm, y'all may have the nozzle clogging issue.
    If the table surface is uncovered, please cover the table surface with sheets to foreclose the UV reflection from the table surface.

    Caution2
    If you start the "Gap Bank check" part with the following conditions, the "actual head gap" will be larger than the head gap you fix. Therefore verify yous cleared all following things earlier start doing the "Gap Cheque".
    A. "Cloth not aptitude and it is flat"
    B. "The jig is non bent and it is flat"
    C. "No loose tape or dust on the material or jig surface"

    D. "Material is not popped out from the jig"

    Due east. "No meridian difference betwixt materials"
    If height difference is large, you may have ink mist upshot on the lower pinnacle material surface.
