1. When loading and unloading ink cartridges, the power supply to the machine must be cut off first.
2. If the machine is not used for more than 20 minutes, the ink cartridge must be removed from the machine. Use the clip to clamp it. [Be sure to save the card holder]
3. The data given by Hewlett-Packard requires that after the ink cartridge is opened and powered on, it is best to use it within 3 months.
4. Because the ink cartridge is quick-drying, it is normal for a little wire drawing and missing wires to occur during use.

5. If wire drawing or missing wires occur.
Method 1: Use a soft paper towel to wipe the nozzle in one direction. [Do not damage the nozzle with hard objects]
Method 2: Change the vertical resolution to 300 in the advanced menu, and change another nozzle (left or right) to re-transmit the information.
6, if it is quick-drying white ink, shake it for 5-10 minutes before each use, otherwise the color will be lighter. [Be careful not to shake too hard]
