Causes: First, caused by misalignment of the print head during the transportation or moving of the printer, and then the print head may also cause misprinting of characters when it crashes during use. The workaround is to use the print calibration procedure provided with the printer to align the print heads. If you do not have a print calibration program at hand, you can solve the problem by setting the printer to print in one direction when printing, but this will affect the print speed.

Print head crash handling

The causes are as follows: 1. The print head control circuit has failed. 2. The print head mechanical parts are damaged. 3. The print head has too much resistance at work. In the long-term use of the printer, the author discovered that the first two cases are very unlikely. Most print head crashes are caused by the third condition because the printer controls the print head movement during use (as shown in the figure. The oils on the 1 and 2 shown above form grease with the dust in the air, and accumulating for a long time will make the print head more and more resistant when moving. When the resistance is large enough, it will cause the print head to crash.

Due to this reason, the failure of the printhead crash is well eliminated. You can find some absorbent cotton and some high-purity sewing machine oil. First use grease absorbent cotton to clean the grease on the guide rails shown on the 1st and 2nd, and then use the absorbent cotton on some Repeatedly wipe the two guide rails with the sewing machine oil (Caution: The sewing machine oil should not be too large to prevent the oil from dripping on the document during printing to affect the print quality) until black grease is no longer visible.

Some printers only clean the guide rail shown in Figure 1 on it. Generally, the noise of the printer will increase significantly before the print head crashes. To prevent the print head from crashing, you can use this method to clean the print head guide every 2 to 3 months so that your printer can always work in a good environment. under.
