  • Failure phenomenon:Airbubble issue
    Cause of failure:

    1.Air is inside the ink
    2.The Pump volume is too large
    3.Too less ink in the inking tank
    4.The length of recovery hoses is short
    5.Viscosity is too high
    6.The PH is too high
    7.Recipe is incorrect

    Resolvent:

    1.Check if the seals are problem
    2.Ensure the ink volume in the inking tank
    3.Use a long inking hose in the recovery system
    4.Decrease the viscosity of ink
    5.Reduce the PH by adding new ink
    6.Add defoaming agent

  • Failure phenomenon:Superimposition is not perfect
    Cause of failure:

    1.Dry is too slow in printer 1
    2.Anvil pressure of printing section is not correct
    3.Color sequence arrangement is incorrect
    4.The LPI of printing plates are not matching with the LPI of anilox
    5.The printing plates are hardening or wear out

    Resolvent:

    1.Increase the dry temperature in the printers , or add dry agent in printer 1
    2.Adjust the anvil pressure
    3.Arrange the proper color sequence
    4.Replace the anilox
    5.Replace the printing plates
    6.Improve the abrasion resistance

  • Failure phenomenon:Dim printing
    Cause of failure:

    1.excess ink
    2.The anvil pressure is too much
    3.The viscosity of ink is too high
    4.The ink is dry quickly
    5.Some foreign matter on the printing plate
    6.Too much pressure toward the anvil pressure of diecutter.

    Resolvent:


    1.Reduce the inking volume of anilox
    2.Decrease the anvil pressure of printer
    3.Reduce the ink viscosity
    4.Add the slow dry agent
    5.Clean the printing plate
    6.To raise the wearability of ink and decrease the anvil pressure of diecutter

  • Failure phenomenon:Recovery function is down in inking pump
    Cause of failure:

    1.The hoses and collecting box of inking system are blocked
    2.Pump is down, if it is double diaphragm pump,its recovery port is blocked
    3.Air pipe leakage and the recovery valve is not working
    4.Air leakage or the air pipe is drop from the cleaning valve
    5.The main water valve is down

    Resolvent:

    1.Replace the recovery hoses , clean the ink tanks
    2.Clean the ink pump
    3.Check or replace the recovery valve
    4.Replace the air pips toward the recovery and cleaning valves
    5.Check if the main water valve work properly, then check the filter of valve, clean the filter

  • Failure phenomenon:Inking function is down
    Cause of failure:

    1.Air pipe leakage or drop from the inking pump system
    2.Problem with solenoid valve of ink pump system
    3.The inking pipes are blocked
    4.The pump diaphragm is broken
    5.The inking filter is blocked
    6.The inking pipe and connector of pump are not tighten properly

    Resolvent:

    1.Check the air tubes to ensure there is no leakage there. Replace the pipes and air connectors
    2.Remove the water from the filter device regularly, dry the air by adding a dry device. If the valves can’t work in manual mode, have to replace it.
    3.Replace the inking tubes or clean them
    4.Replace the diaphragm or the inking pump
    5.Clean the filter
    6.Tension or replace the hose clamp, stop the leakage from the inking pump, to make the pump run normally

  • Failure phenomenon:Register variation
    Cause of failure:

    1.The air pressure of unit lock cylinder is not enough
    2.Improper anvil press or improper register position
    3.The printing cylinder and anvil roll are not parallel
    4.Printing plates are not tightened
    5.Improper adjustment toward the pulling gap
    6.The size of paper is too small
    7.Abnormal fan cylinders or air leakage of the fan doors in feeder or printer units

    Resolvent:

    1.Check the air pressure and make sure all the air tubes are in good condition
    2.Adjust the anvil pressure and register position
    3.Adjust the parallel toward anvil roll and printing cylinder
    4.Tension the ratchets to tighten the printing plates
    5.Adjust the pulling gap , its size should be about 80% of paper’s thickness .
    6.Run the paper of proper size.
    7.To check the air tubes and solenoid valves, ensure the fan cylinders are working properly.
