Training on fixing the failure of banner and flex printing devices

Banner printing machines are one of the main parts in advertising, whose many advantages have made it popular among people, and the main reason is the reasonable and affordable cost of this printing method. This printing machine is used for very large size signs on the streets and in stores, and two types of banner and flexi materials can be printed, the difference between banner and flexi is in the ability of light to pass through flexi.

Banner and flex printing devices are used continuously due to their many uses, and this may cause them to fail. When the banner printing machine finds a technical problem, it should be checked and solved by a specialist technician, but in the case that the problem is minor, the operator who works with the machine can also solve it.

Training on fixing the failure of banner and flex printing devices

In general, it is not possible to provide a single instruction to solve the problems of banner and flex printing machines, but in some situations, minor daily problems may arise and raise questions for the operator, in this case, the following guide can be very effective.

Does the banner and flex printing machine need to be greased?

The lubrication of gears, rails and bearings in flex and banner printing machines helps to increase the life of the mechanical parts of the machine and causes the smooth movement of the crease on the main rail and as a result increases the quality of printing.

What should be done in case of delay or non-functioning of roll opener sensors of banner and flex printing machine?

In addition to checking the sensor section of the roll opener, the gears related to this section and the electrical systems of this printing machine, you must check the angle of the eyes relative to the horizon so that they are correctly positioned.

What should we do if the motors of the banner and flex printing machine do not turn on?

At first, you should check if it is a software problem, then the server and engine of the printer should be checked, and if there are no problems, the power supplies that supply the input power to the engine and server need to be checked.

What should be done to fix the failure of the pump of the flex and banner printing machine?

•    You need to make sure that the command is transferred from the board to the sub tank.

•    Remove the paint clot or blockage in the sub tank float by opening and washing it.

•    Then make sure that the power reaches the compound pump.

•    Check if the compound pump has air or not, in this case you must bleed it.

What should be done if the rivet buttons of the flex and banner printing machine do not work?

•    First, you should check the pump, magnet and air sub tank.

•    Then the air hose connections should be checked on the way.

•    Check the compound sub tank for air leakage.

What should we do if we turn on the banner and flex printer and it is not ready to print?

Optical fiber parts, input power system, device fuse and start switch (if any) should be checked.

If the operation of the banner printing machine was done correctly, but the color splash did not occur and white printing was done, where does the problem come from?

•    Make sure the head voltage is properly supplied.

•    Check that the head socket cable is not loose.

•    Check the input power wiring to the power head.

If the heaters of the flex and banner printing machine do not work, what should be done?

After checking the power of the device and the heater screen, you should then check the SSR systems inside the power box.

What should you do when the heads of flex and banner printing machines are clogged?

The under head must be cleaned, which can be done in three ways:

•    Clean it with a special head spoon.

•    Using the automatic clean feature of the banner and flex printing machine.

•    Using manual or automatic purging of the device (if you use this method, note that you should use a special napkin to clean the plate; the napkin should not touch the head because it will dry it and may damage the head damage.)

What are the causes of head clogging of the banner and flex printing machine?

•    Long-term use of low-quality inks.

•    Combining two types of ink.

•    Changing the standard temperature and humidity for the environment where the printing machine is placed.

•    Presence of dust in the environment.

•    Non-adjustment of Sarhad input power.

•    The device's earth well does not work properly.

Why are white grains created in banner printing?

•    Using inappropriate ink (which can be solved by changing the ink).

•    Use of inappropriate salon.

•    Solvent penetration inside the nozzle heads.

•    Print media being covered with dust.

•    Banner printing machine not working properly.

Why is the air sub tank in the flex printing machine filled with ink?

If the float of the ink sub tank does not work properly, the ink will be transferred into the air sub tank and penetrate into other colors through it.

What problems will occur if the air sub tank (air tank) is filled with ink?

In this case, the purge of the banner and flex printing machine will not work and the air magnet may also be damaged.

How many degrees should be the standard temperature and humidity for the environment of the flex and banner printing machine?

The temperature of the environment is between 27 and 30 degrees and the humidity is about 40 to 60 percent. Also, the environment of placing the banner and flex printing machine should be free of any kind of pollution and dust.

How does the existence of a problem in the encoder strip affect the banner printing machine?

It may give various errors on the computer, or the damaged parts may not print, or the print may be rasterized or shifted.

What does the optical fiber error message in the banner and flex printing machine mean?

This message means that the cartridge board of the printing device is damaged, and to fix it, the optical cables of the device must be tested first, because there may be a problem with the input power of the cartridge, and this problem will be solved by replacing it.

What actions should be taken when turning off the flex and banner printing machine?

You must put salon or so-called cap under the heads. If the printing machine is off for more than 48 hours, the heads and the pump must be washed with solvent to prevent the pump from drying out and damaging the heads.

What is the reason for the existence of many lines in printing on banners and flex?

•    Use of inappropriate composition.

•    The air system of the printing machine is not working properly.

•    Improper operation of the roll opener.

•    Weakening of the media moving motor.

•    Thinning of pinch rollers.

Why is the earth system used for large format printing devices?

•    To protect printing devices and people: because the over voltages produced in the body of the printing device cause them to be damaged.

•    Dangerous voltages caused by lightning strikes with computer towers should be neutralized where an earth well provides this situation.

Why should printing houses be equipped with earth wells and stabilizers?

The stabilizer is used to stabilize the electric voltage and prevent noise on the boards, and its absence causes the device board to burn and cause problems for the heads of the banner and flex printing machine. The absence of an earth well also increases the possibility of the device board burning.
