1.3. Requirements for Environment The ink jet plotter should be away from the seaming equipment (cloth seaming machine) or other radio frequency source. The floor is easy to clean and free of dust and static electricity. Fitment of neutral gray color and pure white lighting such as daylight lamp should be used as much as possible in order to help operators and users distinguish the color accurately. 11

MYJET Digital Ink Jet Printer Operation Guide

The ink jet plotter should be installed in a clean and dust free environment of which the temperature and relative humidity are controlled in the following range: Altitude: used under the altitude of 1000 meters. Temperature: 18 to 28 degrees centigrade. Relative humidity: 40% to 60%

1.4. Requirements for the Floor

d

The materials of the floor in the working region should guarantee the safe and even weight dispersion of the system. During the installation, the system should maintain accuracy and precision in order to ensure that printing head moves horizontally in a correct way and avoid gliding and bending. The materials of the floor in the working region should be free of static electricity and dust. If necessary, clean ceramic tiles, polished cement or anti-electricity carpet could be paved in the working region before the ink jet plotter is installed.

re

1.5. Requirements for Load bearing

is

te

The net weight of X3216A ink jet plotter is 540 kgs and the biggest coil stock usually adds up 50 kgs. It is suggested to install MYJET printer on four steel plates of 20 centimeters in diameter each or on four steel plates with an area of over 200*200mm and a thickness of over 8 mm each.

eg

1.6. Requirements for Space Reservation

nR

The front of ink jet plotter is the input border. MYJET ink jet plotter is required to reserve 2.0 meters in the front, 1.0 meter at the back and 1.0 meter on both sides. Besides, the space reservation area also includes a height of 3 meters above the ground. Moreover, space should be spared at the front and back of the machine for loading and unloading media.

U

1.7. Safety Requirements

Fireproofing The ink and solvent should be installed in the special store cabinet for inflammable liquid or in the independent storeroom. They should be clearly labeled in accordance with the requirements of the professional safety regulations. The storage of ink should strictly comply with the local fireproofing regulations of using and storing inflammable matters. Carbon dioxide or dry powder fire extinguisher should be placed in all the passageways where it’s easy to be seen and obtained. They should be put near the X3216A ink jet plotter and the store cabinet for inflammable liquid or according to the local fireproofing regulations. u Aeration In order to prevent the potential danger of volatile gas storage, enough aeration should be guaranteed to insure 6 to 8 times of air change in the working region every hour. The air outlet should be positioned as low as possible so that the volatile gas could not accumulate around the floor. u

12

MYJET Digital Ink Jet Printer Operation Guide

The solvent in the ink volatilizes when the cloth is going through the drying apparatus. So an exhaust gas outlet system is needed to discharge the solvent. Notes: the solvent gas is heavier than the air and will accumulate around the floor. The electrical apparatus installed near the working region should comply with GB/T standard and the regulations concerning Class I Category II in the National Electricity regulations, and they should be installed by the professional electricity contractors with related qualified specialty. The regulation of handling the dangerous waste should be in accordance with special storing and disposing requirement set by related sections.

Printers need to knot all the printing content tighter when printing, which need to adjust the revise color excursion value of each print head. The excursion value are often different in different printing direction, so can be revised according to direction. Click the menu item of printing revise color excursion, and print corresponded revised image , printing image will compose more revised unit. The each unit can correspond to the revise parameter of each print head according to the color and the direction that mark the printing direction and the print head group No. We can see the excursion of print head correspond direction when adjusting, the method of reading is as following, there are tens digit and entries digit reading area. There are correspond digital marked ,black line is datum line, find the best superposition line that the color line and basic line that tens digit and entries digit corresponded, and add the figure that the two line show and get the excursion value. In order to facilitate reading, when there is the excursion value no less than 10 in the image, firstly, correct the excursion of tens digit, then print again to correct the entries digit, but in general condition, as system exist standard excursion parameter of corresponded machine. As excursion parameter is less than 10, so once correct can make all the revise color excursion value, make the value add the original excursion parameter and fill into the correspond print excursion parameter table which shows in the following.

The print image also can reflect the excursion of print head in Y direction, as the grades line circled in the image.

33

MYJET Digital Ink Jet Printer Operation Guide

The print image also can reflect the excursion of print head in Y direction, as the grades line circled in the image. When the current printing form is print head combination, Y direction warp revise can be performed, and other scheme form can be adjusted only by mechanical method .The method of reading warp value is choose the level line sect that superpose datum line well, and get a warp value by making the entries digit that this line corresponding multiply constant 48, then fill the wrap value in the correspond Y direction warp figure frame. Of course ,users can make a slight adjust within 48 figure.

of correspond speed.

nR

eg

The method of reading trip dispatch is same as the revise color excursion, that is, firstly read the warp of tens digit ,and then the entries . Make the warp value add the figure in the original software trip dispatch frame and fill the result in the figure frame

In order to explain the method of reading, we make a local explain about the printing image of trip warp shown as follows:

The black block in the picture is not neat with the uprightness border while printing. The black block means the exist of trip dispatch .Compared the superposition state of each reading line and datum line, we can found line three sect are in good match with datum line, so the new trip dispatch will get by add the trip dispatch of current printing speed to line-3. 34

If the printer is not in use for more than 48 hours, the ink in the printhead must be cleared, otherwise, ink will dry as solvent volatilizes or even impair the nozzle permanently. Treatment is as follows: Turn off printer's power supply Move the printhead to the leftmost cleaning position and put an anti-erosion receptacle below the injection cup to contain waste liquid. Aspirate with glass injector or directly pour out ink in the secondary ink tank. Then, wash it thoroughly with special solvent. Pull out the ink supply tube (from secondary ink tank) and aspirate 40ml special solvent with glass injector to clean the print head twice. Don't blow away residual solvent in print head because solvent inside the printhead can keep it wet. Discharge the print head bracket, wrap it with the plastic bag and or film.

Any ink factory or distributor relies on profits to do business continuously. We recommend our ink. Although the price may be a little higher than the cheapest ink available in the market, the cost is quite low if it is distributed on each square meter. Poor ink will damage the printhead and break the line seriously within one month. So the bad image will be printed. Naturally customers will purchase less ink by poor quality as time goes by.

pre-condition is no line breakage in long image printing Remember that damage to the print head starts from a small hole. Many operators let the printer run through to the end of the image printing because they don't care about one or two broken lines. What they don't know is the injection hole that does not spray ink due to delayed cleaning, affects neighboring injection holes. "What we must do is to prevent things from happening before they actually happen!" u

At intervals of printing, do not turn off the printer. Keep the print head in the state of flash jetting. Ø During the process of flash jetting, ink consumption is very small (only 2‰ of that in normal printing). This keeps the injection hole moist. At the same time, keep the normal print head temperature. Make sure when printing starts, print head are in best working conditions. Ø

When operating Myjet printer: first turn on the computer, then start up the printer and print head voltage .Choose reset when entering the system.

Ø

If the ink jet plotter is turned off, you need to press the key RESET to restart the system. Only in this way can the print head return to the left side for automatic flash injection. To ensure the 57

MYJET Digital Ink Jet Printer Operation Guide

proper function of flash injection, you may use a piece of paper to check whether it works well or not. Examine jet hole before or during printing: Ø Before printing, if ink isn’t found flowing out of a jet hole, firstly try to suck it by injector or adopt air pressure way,repeat it until the jet hole flows. Ø The disconnection in the process of printing is usually due to the conglomeration of ink, which can easily be solved by using nonwovens to clean. Ø The practice of spraying painting should be stop, when a disconnection occurs. otherwise, the jet hole would be clogged with the accumulated ink. Ø If you fail to deal with, please promptly consult the technicians at the supplier’s for detailed information.

After the shutdown, immediately cover the print head with the bonnet (equipped with cleaning solvent and non-woven fabrics), for the sake of preventing the surface of print head from direct exposure to the open air. If it were not done, the ink would evaporate and the resin in the ink might clog the jet hole. If print head is found out of order, 2mm of solvent can be injected onto the bonnet and then cover the cup so that its surface is immersed into solvent till tomorrow.

1.2 Adjust the relative positions between the print head of one color and the print head of other colors. For the first adjustment, mechanically adjust the screw and put the test bar in the very position, Second, run the software to further adjust the print head in a proper position. Then use the adhesive to fix the screw so that the screw won’t be dislocated by vibration. Prior to daily operation, first print the test bar, and then check whether each jet hole is in good order and whether the relative position and parallelism of each print head are within the permissible error range. Then can produce high quality images only when all the requires can reach. Since the way to inspect and adjust varies from one factory to another, users should be familiar with this 58

2. Adjust the clearance To achieve the satisfactory effect, it is necessary to adjust the headstock so that the clearance between it and the material to be printed, can be reduced to the minimum, 2.5 mm—3.5mm (Notice: material isn’t allowed to be touched.)

nozzle frosted and broken. When cleaning the surface of nozzle, we must use the special paper or non-woven fabrics instead of the tissue paper to clean the surface of print head. With untold tiny fibers on its surface, tissue paper can gain easy access to the nozzle. Additionally, the tiny hairs that remain on the surface of nozzle probably lead to the clogging and dripping of the ink and then affect the print quality.

u

Accessory Ø Every accessory serves certain purpose and shouldn’t be detached at random. Ø Keep intact the primary ink box and the air filter of the secondary ink box so that the particles of various kinds floating in the air can be denied access to the ink. If clogged or even broken, they should be promptly replaced.

u

Static Ø Ø

Ø

Ink jet plotter should be connected with zero line to prevent the static’s effect on the print head. Maintain a constant temperature in the working environment and ensure that the temperature ranges from 20 oC to 28 oC because the heat generated by the working print head is mainly carried by the ink and then discharged from the heat sink. The humidity in the working environment should be within the range of 40%-60%.If it is too 59

u

Ink Ø

Ø

The quality of the ink exerts direct effect on the image quality. The lower price doesn’t amount to the decreasing cost. Instead, the ink of inferior quality is more likely to bring about the following consequences. For example, print head is clogged, printing is stopped, product is discarded as useless and customers ask for refund because the product is of poor color quality. Then it may cause considerable waste. Users are strongly recommended to use the ink supplied by the manufacturer and its agents on account of the fact that the ink that has been strictly and persistently tested is helpful to maintaining both the equipment and print heads.

d

Maintenance Ø Maintenance is very important to prolong the working life of the printhead. After turning off the printer, be sure to put the cleaning solvent on the surface of print head and cover the nozzle with the preservative film so tightly as to reduce the evaporation of both the solvent and ink. It will, to a great extent, extend the service life of print heads. Ø If the machine is out of service for a long period (during the long holidays, for example, International Labor Day, National Day, Spring Festival), users must put the solvent into the print head and then cover it with the bonnet. Besides, more solvent should be added to the bonnet. Finally preservative film can be adopted to enclose the whole print head for the purpose of preventing the dust’s penetration and reducing the evaporation of cleaning solvent.

dry, medium will be charged with static, thus affecting the print quality. Generally, static that exists in the zero line of the equipment, in the particles floating in the air and in the friction between medium and equipment, together with the leakage of the equipment, may charge the main body with electricity, which does harm to the major accessories including print head, main board.

u

u

u

U

4.1 The techniques for slight clogging of the nozzle If the nozzle is found slightly clogged in the process of printing, don’t hesitate to press the key PAUSE to stop printing. Then use a vacuum cleaner to suck the clogged ink out of the nozzle. By means of this method, we can clean the nozzle. Afterwards, cleaning solvent should be taken to wash away the residue. (Notice: Vacuum cleaner should not be utilized to suck a given injection too many times, otherwise, it will likely to damage the print head.) The prompt, resolute and thorough treatment to the slight clogging is of paramount importance to maintain the optimum working state for the long printing. In addition, it is necessary to carefully examine the print head and eventually discover the reason for the clogging. (If it is due to the ink, change resolutely and make sure that the ink tract be cleaned as well.)

4.2 The techniques for frequent clogging of the nozzle u

Firstly press the key PAUSE to stop printing and then move the head to the leftist cleaning position 60

MYJET Digital Ink Jet Printer Operation Guide u

u

u

u

Generally speaking, the problem can be solved through directly using the vacuum cleaner to suck the print heads. If it still doesn’t work, open the machine and pull out all the signal wires of a liquid level inductor connected to control panel. Then suck the print head, restart printing and observe the possible change. If there is a change for the better, it indicates that the problem originates from liquid level. At that moment you should try to restore the print head to the normal state by adjusting the position of ink box, the temperature of working environment and the working voltage of print head. If there is still no change, pull out the ink-supplying pipe on the print head and use a glass syringe to draw out the special solvent for cleaning the print head. The procedure is as follows: inject 40ml solvent each time and wait for 10 minutes. The process should be repeated 3-4 times. After cleaning, make ink-supplying pipe and the signal wire of liquid level inductor plugged into. Then resume the printing that stopped previously.

d

4.3 Measures taken after the methods mentioned above don’t work. Avoid using non-woven fabrics and directly cover it with the print head bonnet. Then inject 3mm of solvent into the bonnet and enclose the print head shelf with the protective membrane to guard against the evaporation. Notice: The signal interface on the top of printhead cannot meet solvent, or the printheads will be burned.

u

After the print head is immersed in the solvent, use the glass syringe to draw out the solvent one or two times from the interface of the ink pipe, which is on the top of print head.

eg

is

te

re

u

Use the glass syringe to draw out 40ml of special cleaning solvent and then inject the solvent into the

nR

interface of ink-supplying pipe. Next pay attention to the waterline that comes out of the nozzle. If the waterline is straight, it proves that the cleaning is effective and the print head can be further used (The

U

prerequisite is that the circuit and piezoelectric crystal are intact). If it is distorted, then repeat step 2 and step 3 two or three times.

5 Preventing clogging of the print head 5.1 The origin of the clogging u

The ink is of inferior quality.

u

The dramatic changes in both temperature and humidity exert effect on both print head and ink. Ø

The stability of the ink determines the use of the print head of ink jet plotter. On the other hand, its stability is determined by the following factors: viscosity, surface tension, volatility, and fluidity. However, these indexes are not totally decided by manufacturing technique. Actually, storage, temperature and humidity also play the decisive role in the normal use of 61

MYJET Digital Ink Jet Printer Operation Guide

the ink. If the temperature is high, the viscosity will grow low. If it is low, the viscosity will become high. These two conditions can change the previous state of ink and the spotted line or spurious image will thus occur, which is referred to as false clogging.

eg

is

te

re

d

On the other hand, if the humidity is low but the temperature is relatively high, the volatility of the ink will be raised. As a result, the ink is dried into a hard condensate and left on the print head, which may affect the normal function of the print head. However, if there is a high humidity, the ink will accumulate around the hole, dripping and even flowing, which makes the image difficult to be dry. Under such circumstances, it will also contribute to the improper function of the print head. Therefore, attention should be paid to the variation of temperature and humidity at any moment. Even the minute change in humidity may influence the working of print head. On account of the limited ink within the ink cavity of the print head, ink is supplied through syphonage. So the dramatic change in the external temperature is easy enough to disturb the previous equilibrium state. The reason is as follows: the working print head can produce given amount of heat, which enables the ink to be balanced and stable. But if when the weather changes sharply, a sudden decrease or rise in temperature, and there is no device available for regulating temperature, the effect on the print head can appear to be apparent. At this moment, print head fails to function well, the same is true of the ink, even for the ink of the same type. The only way out is to control temperature so well as to ensure the daily temperature range of 3-5 degrees in workshop.
