Diagnosing Print Quality Problems by Pattern
The shape and spacing of a defect tells you which rotating component is responsible.

Repeating marks
Measure the distance between identical spots. That spacing matches the circumference of one roller — commonly the drum, the developer roller or the fuser roller. Matching the measurement to the service manual identifies the part in one step.
Vertical lines and streaks
A sharp black line usually means a scratched drum or a contaminated charge wire. A white line means something blocking the laser path or a clogged developer section.
Faded or washed-out pages
Check toner level first, then developer age, then transfer voltage. On color machines, a single faded channel points to that one cartridge or drum rather than a system fault.
When to bring in a technician
Anything that repeats after a proper reset, produces a burning smell, or involves the fuser or high-voltage section belongs with a trained technician. Austintero Co. serves Centennial and the surrounding Denver metro and can usually be on site the same business day.
