This may be due to damage during transportation or because some customers have accumulated toner powder on the magnetic rod inside the toner cartridge during use.The solution is to turn the drum core a few times in the correct direction.   2Vertical thin black lines appear on the printout: The reason is that the scraper or the small blade on the scraper edge has picked up dirt or paper scraps.   3Horizontal black bars appear in the printed document: The reason is that the magnetic roller in the toner cartridge has accumulated toner powder; rotating it a few times can resolve the issue.   4If there is a noticeable gray background on the printed document: there may be an issue with the drum core or the toner, please replace it promptly.   5The printed documents have uneven colors and visible white streaks: Remove the toner cartridge, shake it well, and then reinsert it into the printer for use. If the problem persists, it indicates that the toner cartridge is depleted.

The solution is simple: just rotate the drum core in the correct direction a few times.   2When more than 1cm parallel black lines of the same width appear on both the printed document and the drum core, customers generally consider it to be a toner leakage: this indicates a problem with the scraper, which prevents the toner on the drum core from being scraped cleanly.   3Vertical thin black lines appear when printing documents: this is usually because the scraper and the small scraper on the edge of the scraper have accumulated dirt or paper scraps.   4Horizontal black lines appear in the printed document: This is usually because the magnetic roller in the toner cartridge has accumulated toner powder; just rotate it a few times and it should resolve.   5Or if there is obvious background graying on the printed document: it usually indicates a problem with the drum core or toner.   6The printed document's color is uneven, with obvious white streaks: If you look at the magnetic roller from the outside, you can see whether there is toner remaining. If you see that some areas of the magnetic roller have toner while others do not, it indicates that the toner cartridge has run out.   7If the printer prints a blank page: first check if there is a problem with the printer. If there is no problem, then it means there was an issue with the toner cartridge during assembly.   8Aside from the above issues, it can usually be considered that the printer has a problem.   (3) Warranty Details:The toner cartridges produced by our company are covered under warranty if the following conditions occur during normal use:1Abnormal noise caused by a malfunction of the toner cartridge itself;2The printout shows issues affecting print quality, such as background gray, black edges, black stripes, and white stripes; (White stripes caused by running out of toner are not covered under warranty.
