As an indispensable part of the office equipment, the printer is also a key point in daily maintenance. Here are a few points to note: 1. The inkjet ink is conductive, if it spills on the circuit board, it should be wiped dry with anhydrous alcohol and then powered on, otherwise it will damage the circuit components. 2. Do not disassemble the nozzle while it is live. Do not place the nozzle in a place where static electricity is easily generated. Take the metal part of the nozzle to avoid damage to the internal circuit of the nozzle due to static electricity. 3. Do not use the mouth to blow air into other ink lines in the nozzle to prevent the saliva from contaminating the inside of the line and affecting the ink flow. 4. The inkjet printer should be used in a clean air environment, especially to prevent rodent damage and avoid being bitten by the ink pipeline. 5. The operating temperature of some printer inks is -10 ℃ ~ + 35 ℃, when the ambient temperature is lower than -10 ℃, the printer ink may freeze; when the ambient temperature is above 35 ℃, it may also affect the chemical stability of the ink Sex.
