Figure 9-1 Print quality page Section 1 2 3 4 Toner cartridge Yellow Cyan Black Magenta ● If dots or streaks appear in only one of the groups, replace the toner cartridge that correlates with that group. ● If dots appear in more than one group, print a cleaning page. If this does not solve the problem, determine if the dots are always the same color; for example, if magenta dots appear in all five color bands. If the dots are all the same color, replace that toner cartridge. ● If streaks appear in multiple color bands, contact HP. A component other than the toner cartridge is probably causing the problem.
