Canon laser printer has a black beltIf a black belt appears on a Canon laser printer, it may be caused by the following reasons:
1. The drum blade is damaged or the drum is scratched by something on the blade;
2. The magnetic roller scraper was partially damaged;
3. The printer (generally guiding the paper path) was contaminated with ink.
The solution is as follows: first observe whether the black belt of the output proof is blurred. If so, clean or replace the drum scraper. If not, then check if there are any scratches on the drum. If there are, check if there is any damage on the drum scraper. Generally speaking, if there is a vertical black line on the output sample, it means that the drum has a more obvious scratch in the vertical (circular direction). This can only be replaced by the drum, but it is also necessary to carefully check if the cleaning scraper has any sticky objects or damage. The scraper should be removed or replaced first to avoid scratching the drum.
