Canon Canon imageCLASS MF453dw 40 ppm Wireless Duplex Mono Laser All-in-One Printer MECH-STREAKS Error Fix: Black Streaks or Lines on Printout

Error code MECH-STREAKS on the Canon Canon imageCLASS MF453dw 40 ppm Wireless Duplex Mono Laser All-in-One Printer means: Black Streaks or Lines on Printout. Vertical or horizontal black streaks, lines, or bands appear on printed pages. Vertical lines (running in the direction of paper travel) are usually caused by a scratch on the drum surface, toner spillage inside the printer, or a contaminated charge roller. Open the front cover and remove the toner/drum assembly. Inspect the drum surface (the green or blue cylinder) for scratches or toner deposits — do not touch the drum with bare skin. If the drum surface has visible damage, replace the drum unit. Clean inside the printer with a dry lint-free cloth to remove any spilled toner. Horizontal bands (perpendicular to paper travel) may indicate a thinning toner supply — remove the cartridge and rock it side to side to redistribute toner. Also clean the transfer roller inside the printer.
