In order to prolong the service life of the jet printer, improve the utilization rate and intact rate of the equipment, and reduce the failure rate. Now we share our daily maintenance and maintenance knowledge with you.
1. Notices for the daily use of jet printers:
1. Because the ink and diluent used in the jet printer are very easy to burn, it is necessary to place the jet printer in a well-ventilated place, away from fire, flame and static electricity.
2. Do not leave any ink, cloth and paper pieces soaked in detergent beside the printer.
3. Smoking is strictly prohibited near the printer. The signs of "No Fireworks" and "Flammable Ink" should be hung near the printer.
4. Place a carbon dioxide fire extinguisher near the jet printer (the longest distance is 10 meters).
II. Notices for Electrical Connection of Jet Coder
1. When connected to 220V single power supply (including ground wire), the original power supply cable must be used and connected to a fixed power socket with ground wire.
2. The connection of ground wires must comply with the relevant regulations of the state. If the ground wire contact is not good, it may cause damage to the printer motherboard or other potential hazards.
3. Daily maintenance matters needing attention
1. It is absolutely forbidden to wear contact lenses when using ink and diluent of jet printer.
2. Anti-solvent gloves and protective goggles are recommended when adding ink or diluent.
3. The daily maintenance process of the jet printer is as follows:
Maintenance of Beijing Printer is mainly pipeline and nozzle maintenance.
a) 墨水更新：先将管路里的墨水全部抽空，稀释剂注入墨水罐运行1h后全部 排出，再次加入稀释剂运行0.5h后全部排出，加入原厂墨水。建议机器每使用一年进行一次墨水更新，保证设备运行更加稳定。（抽出的废液不建议二次使用，以免造成管路堵塞） a) 喷头清洗：对于不具备自动清洗功能的喷码机，建议每天开关机时清洗，以 确保机获得高品质的打印效果。首先在喷头下方放置容器，用专用洗瓶装入稀释剂，对准喷嘴、充电极、检测极、高压偏转板上的墨渍进行清洗，注意不要让稀释剂溅入口眼及皮肤，清洗干净后，用纸巾将喷头各部件的清洗剂擦干。
(a) Ink renewal: first, all the ink in the pipeline is exhausted, diluent is injected into the ink tank for 1 hour, then all the ink is discharged after adding diluent for 0.5 hours, and then the original ink is added. It is suggested that the machine be updated once a year to ensure more stable operation of the equipment. (Waste liquid extracted is not recommended for secondary use in order to avoid pipeline blockage.) a) Sprinkler cleaning: For the sprinkler without automatic cleaning function, it is recommended that the machine be cleaned when switched on and off every day to ensure high quality printing effect. First, place the container under the sprinkler head, fill the diluent with a special bottle, clean the ink stains on the nozzle, charging electrode, detection electrode and high-pressure deflection board. Take care not to let the diluent splash into the eyes and skin. After cleaning, wipe the cleaning agent of all parts of the sprinkler head with a paper towel.
b) 调整墨线：若发现墨线偏离回收器，首先进行喷嘴打通，用专用洗瓶加入少 许稀释剂至喷嘴帽，反复打通3次左右，如墨线始终在同一位置则需进行人为调节喷腔。墨线标准：正对回收器观察，墨线喷入回收器三分之一处且略左。（侧看墨线在回收器正中间）
B) Adjust ink line: If the ink line deviates from the reclaimer, the nozzle should be opened first, a little diluent should be added to the nozzle cap with a special washing bottle, and the nozzle cap should be opened three times or so repeatedly. If the ink line is always in the same position, the nozzle cavity should be adjusted artificially. Ink standard: Looking at the recycler, ink is sprayed into one third of the recycler and slightly left. (Look sideways at the ink line in the middle of the receiver)
2) Maintenance of any downtime of the jet printer after a long downtime, regardless of the length of time, as long as the jet printer runs twice a week, and opens the ink line to run continuously or ink updates for at least one hour, it can replace the long downtime with several short downtime.
1) Inkjet printer shutdown time is 8-15 days: the throat and nozzle are cleaned once, the nozzle is placed upward to prevent ink reflux.
2) The stop time of the printer is more than 15 days. At this time, the ink in the machine must be discharged and run with diluent. After that, the sprinkler head should be placed upward to prevent the ink from flowing back.
3) Start the printer after a long downtime. Notes: Start the printer 8-30 days after the downtime. If necessary, check the stability of the ink line. Make a 5-minute nozzle pass.
4) Over 30 days of downtime
Empty the ink in the pipeline. Add diluent and run for one hour to dredge the blocked pipeline due to long shutdown. When the diluent is running, the nozzle can be opened for 5 minutes at a time. After the diluent is running, the drainage pipe is emptied, new ink is added, and the nozzle is opened for 3 minutes to make the ink line position more stable.
5) 喷码机维护保养周期。 每15天对喷码机管路进行一次检查，是否老化、接头是否松动 更换过滤器。该操作视环境而定，如粉尘较大至少每隔4个月更换一次，正常情况下应该每隔12个月进行一次。机器内部除尘。该操作至少应该每隔1个月进行一次。
5) Maintenance cycle of jet printer. Every 15 days, check the pipeline of the jet printer, whether it is ageing, whether the joints are loosened and the filters are replaced. The operation depends on the environment. If the dust is large, it should be replaced at least every four months. Normally, it should be done every 12 months. Dust removal inside the machine. The operation should be performed at least once every 1 month.
IV. Notices for Use and Maintenance of Consumables for Printers
1. The consumables used in the jet printer are highly volatile. They should be kept below 35 degrees, avoid high temperature and keep away from fire and heat sources. They must be well sealed and stored in a shady and ventilated place (in a thick-walled iron cabinet with good sealing).
2. The shelf life of consumables of jet printer is one year.
3. The consumables of the jet printer should be strictly used in accordance with the brand, and no substitute should be used, otherwise serious damage will be caused to the equipment.
