Chapter one: brief introduction 1, Power safety Cautious: for safety of the person and the machine, make sure to connect the ground wire. Inkjet machine uses AC 220V/50Hz power supply. If the voltage fluctuation range is large (over 187-242V), it can cause problems such as not starting the machine, burning out the main board and motor, etc. At this time, it is necessary to install an automatic voltage stabilizer to cooperate with the use. Must use standard grounding socket. Do not cut or remove the grounding of power lines. The plugs should be accessible after the machine isinstalled in place. Power cord plugs should maintain strong contact with the socket, otherwise, may lead to fire. Do not use damaged, modified, loosened power cord or plug. Arrange the power cord and cable line neatly to prevent people from tripping down. When unplugging power cord, do not fold, twist, pull, circle or pinch power cord. Grab the plug and pull it out of the socket directly. Do not pull the power cord with wet hands. Avoid using sockets in the same circuit as devicesthat switch frequently between on and off, such as photocopiers or air conditioners. Avoid using sockets controlled by wall switches or automatic timers. 2, Attention in operation of machine The data cable should be inserted behind the computer, not in the front. Use the emergency stop switch on the machine to stop the machine when you experience an emergency . Do not put your hand inside the machine parts when operating the inkjet machine, otherwise it will cause injury. In the daily use the machine should be kept clean at all times, to avoid dust deposition. The printing carrier must be installed at the set position, otherwise it will cause the printing carrier to fall and cause damage. In addition to moving the machine or dumping waste ink, ensure that waste ink bottles are always installed on the machine in other time. Please do not put tools or other items on the inkjet machine platform or cover board so as not to cause unnecessary losses due to untimely cleaning before the operation of the machine. Always use the powerswitch to turn off the inkjet machine. (the powerswitch is behind the rightside of the inkjet machine) do not unplug the power plug or otherrelated data lines before the machine powersupply is cut off. Operatorsshould develop the habit of making operation diaries and record the best

47 / 51 http://www.smart-jet.com Guangzhou Ruizhi Digital Science&Technology Co., Ltd. Chapter five: maintenance guideline 1, cleaning of machine When the machine needs cleaning Clean the pinch roller wheel, gently wipe it with a dry wet cloth. Do not use solvent cleaning fluids (e. g. Gasoline, diluents, etc.) Please turn off the power switch and unplug the power cord before cleaning the inkjet machine. for dust around the printhead, wipe with a special cloth or dip a small amount of cleaning liquid with a cleaning rod. Never wipe the nozzle surface with any other medium, which may cause damage to the nozzle and cannot be repaired. Wash the pressure plate and gently wipe it with a dry wet cloth. Wash the pressure plate regularly. If the pressure plate becomes dirty, it will affect the printing. Clean the body, front cover, gently wipe with dry wet cloth; use dry, clean and soft cloth when wiping operation panel, display, etc. Clean the wheel, use a brush to remove dust and impurities from the wheel. Clean the wheel horizontally with a brush while turning the wheel. The dust adhered to the grinding wheel will affect the normal movement of the medium. 2, Ink supply system maintenance Ink supply process: floating ball drop then switch on (that is, secondary ink cartridge lack of ink), ink supply board corresponding lights on, ink pump begins to pump ink in, when the secondary ink cartridge full, ink pump stop pump ink. (ink supply system must be cleaned at least once every two month.) Cleaning step: 1, Put the ink tube that is inserted in the ink into the cleaning liquid and pumped into the ink tube by ink pump. 2, Unplug the ink inlet tube on the secondary ink cartridge and connect it to the waste ink bottle. 3, Make sure the ink in the ink tube is washed by cleaning fluids, wait until the ink in the ink tube is completely drained. 4, Finally re-insert the ink tube into the ink bottle (note: at this time, do not pull out the ink tube inserted in the waste ink bottle until ink forces out all the cleaning fluids in the tube, then connect it to the secondary ink cartridge). Note: observe whether the ink tube in the tank chain has broken or has ink leakage every day when the machine is turned on or off. Prevent ink leakage from breaking the data line in the tank chain, resulting in a short circuit, thus causing more serious consequences.

48 / 51 http://www.smart-jet.com Guangzhou Ruizhi Digital Science&Technology Co., Ltd. 3, Printhead maintenance 3.1 Maintenance of printhead after daily work After finishing all the printing operations every day, in order to keep the printhead in the best working condition, and because the inkjet machine uses solvent ink, easy to volatilize so as to block the nozzle, please follow the following methods to maintain the printhead after working every day. 1) turn off the power supply of the machine. 2) Wash the moisturizing sponge with a special cleaning fluid. 3) pour the cleaning fluid on the sponge and wet the sponge completely. 4) remove the carriage back to the carriage station and combine the nozzle with the sponge in the cleaning station. 5) keep the printhead in this state overnight. 3.2 Treatment of printhead after slight blockage 1) the nozzle is found to be slightly clogged in the process of printing. Press pause button to stop the machine. 2) using a vacuum cleaner or a manual air pump to spray ink from the nozzle and clean the nozzle. 3) after the nozzle is cleaned , remove the residual ink on the surface of the nozzle with cleaning fluid . 4) check the printhead situation carefully, find out the cause of the nozzle blockage, and make a good record. 3.3 Treatment of printhead after serious blockage 1) turn off the power supply of the machine. take off the nozzle. 2) In a clean glass container, pour appropriate amount of special printhead cleaning fluid. Place the nozzle in the glass container and immerse the nozzle. (about 2-3 mm at the bottom of the printhead) 3) seal the glass container with a plastic film and set it still for one day. (do not contact cleaning fluid with the signal interface at the top of the nozzle) 4) after soaking the nozzle, pour a proper amount of cleaning liquid into the special printhead cleaner. 5) immerse the nozzle in the cleaning fluid 2-3 mm and start the cleaner to clean the printhead. Do not wash the printhead more than three times by using the cleaner continuously, so as not to damage the printhead. 6) extract 40ml cleaning fluid with syringe. inject it from the ink supply tube interface at the top of the printhead. Observe the water line state ejected from the nozzle. If all the water lines are straight and indicate that the cleaning is effective, you can continue to use this printhead. If there is still some water line skew, re-wash 2 - 3 times. If still not valid, the printhead is broken and the printhead needs to be replaced.

Otherwise, ink will dry due to the gradual volatilization of solvents, resulting in ink breakage, no ink and other phenomena. Serious damage can even be irreversible to the nozzle. The approach is as follows: 1) turn off the power of the machine. 2) move the carriage back to the carriage station and place a corrosion-resistant container under the nozzle to hold the cleaning waste water. 3) use glass syringe to extract or directly pour out ink from the secondary ink cartridge, and then clean the ink cartridge with a special cleaning fluid. 4) unplug the ink supply pipeline connected to the ink supply bottle, connect the ink supply pipe connected to the nozzle into the waste ink bottle, and clean the ink supply pipe with special cleaning liquid. 5) extract 40ml cleaning liquid with glass syringe, and inject it into the printhead to clean the nozzle. Wash repeatedly 2-3 times. 6) after cleaning the printhead, be sure to keep enough cleaning liquid in the printhead. Cleaning liquid has a moisturizing effect on the nozzle. 7) place the treated nozzle in a corrosion-resistant container and seal it. (e.g. sealed with preservative film) 4, Influence of static electricity on machine the machine not grounded, working environment temperature and humidity and other reasons may cause static electricity. Static electricity will cause ink dropping, ink breaking and so on, which will not only affect the quality of printing image, but also damage the nozzle. Improved method: The working environment of the machine keeps constant temperature as far as possible. The temperature is controlled at 20-28 ℃. Take seriously the question of grounding. Be sure to plug the inkjet machine into a socket with a ground wire. The working environment of the inkjet machine is well ventilated and the static electricity generated by friction is transmitted out of the air. Medium selection: the roughness of the surface of the medium will directly affect the production of static electricity. Try to choose paper better, surface smooth medium. The humidity around the machine is 40-70% relative humidity. Humidifiers can be used in dry areas, or in sunny weather, to humidify the working environment of the machine.

Lubricating oil step: 1) with a lubricated grease gun, point the tip at the slider injection nozzle. 2) fill the nozzle with lubricating oil. Note: this oiling must be operated with a special grease gun. Other tools cannot work. 3) until the oil overflows from the gap between the slider and the rail. 2, Do the same thing between the synchronous belt and the synchronizing wheel. 3, you may add sewing machine oil or light oil between both guide rail and slider wheels if machine has two guide rails. oiling time is once a week. 4, other parts shall be based on the actual use of the machine: a. pinching bar of the media pinching system b. Reducer pulley bearing c. main shaft bearing
