Routine maintenance and repair methods of large format inkjet printer

large format inkjet printer is a large output device with high cost of use and repair. Therefore, special attention should be paid to the correct use and maintenance. The following are the basic maintenance methods of the inkjet machine, which are provided for your reference, in order to help your inkjet machine be in normal operation for a long time

pay attention to good use environment

1 There is a precise print head in the internal structure of the inkjet machine, so mechanical collision and vibration should be avoided during placement and daily use

2. Because the size of the nozzle of the inkjet printer is the same as that of the dust floating in the air, and it is expected to replace soft polyvinyl chloride (PVC) in medical devices, it is easy to be blocked by dust. Therefore, it is necessary to keep the environment clean and avoid the dust in the air blocking the nozzle

3. The temperature of the working environment of the printer should not be too high to prevent the mechanical parts and nozzles of the printer from being rusted; The temperature change should not be too large, because the inkjet printer contains a large number of engineering plastic parts, and the nozzle aperture is very thin. If the ambient temperature changes too fast, the thermal expansion of the parts will cause the wear of mechanical parts, and the change of the nozzle aperture size will also affect the print quality

2. establishment of index library selection of ink

4 The quality of inkjet determines the quality of the printed image and the service life of the nozzle. Inkjet printer ink is divided into original ink and compatible ink, and it is better to choose original ink as much as possible

print head maintenance

5 Choose a high-quality ink cartridge, otherwise the nozzle will be blocked and the print quality will be affected, and even the whole print head will be scrapped in serious cases

6. Ink cartridges that are not used for a long time can be stored in the ink box to avoid nozzle blockage

7. For normal printing, but lack of strokes or colors, or blurred images under high resolution, use a theodolite with a minimum vertical angle reading of less than 2 to observe the slight blockage of the vertical angle, and use the nozzle cleaning program provided by the printer as soon as possible

8. If the machine frequently fills ink or cleans the nozzle during printing, but the printing effect is still poor or the nozzle is seriously blocked, and the printer refuses to work, professional maintenance personnel should be invited to repair it. Do not disassemble the nozzle at will. The above methods (1) - (4) detect the geometric isometrity of the experimental machine to avoid damaging precision parts
