My printer hasn’t printed for a long time, now the printer report shows that the print head has a problem, how do we do? LKB Answer: ① Your printer at least needs to print 1~2 pages twice a week. ② Soak the print head nozzle into hot water with around 75°degree almost 2 hours or half day. Note: 1. Our print head is remanufactured, not original one, Non OEM value-save more for you; 2. Please shake the print head before installation, it will avoid bubble problem in the ink. Kindly note the bubble in the ink will cause your printer can’t print well. 3. When you replace the print head, please do Printer Head Cleaning 2~3 times every time.
