Unplugging and inserting the ink cartridges with power on will cause damage to the machine and the ink cartridges. 5. The ink cartridge is scratched and bumped, which will cause the ink cartridge to be unusable 6. After stopping use, if the ink cartridge is not removed from the machine, and the ink cartridge cover is not installed, the ink cartridge may be unusable. 7.

FAQ
1. Are the original HP ink cartridges? Yes it is 2. How many products can be printed on a box of ink cartridges? The printing volume of the product is determined by the printing information of the product. If a simple production date such as "MFG: 06/11/2021" uses a 3mm dot matrix font, about 270,000 products can be printed. If you use physical fonts, larger fonts, and more print content, the number of prints will decrease. It is recommended to use bitmap fonts, as the cost of consumables is lower. 3. Ink cartridge maintenance problem? The ink cartridge is not easy to block the nozzle. No solvent cleaning and maintenance are required for daily use. When you only need to stop longer printing time, take out the ink cartridge from the machine, close the ink cartridge cover, and put it in the packing box.
