Follow the model menu and allow completion.

caution

Do not touch drums, belts, or printhead surfaces

Fingerprints and scratches can permanently damage imaging parts.

Professional

What pattern do the lines follow?

Same place on every page

A roller, drum, belt, or fixed nozzle area is likely.

Only one color is affected

Focus on that cartridge, channel, or printhead color.

Lines appear only from one app

Check scaling, driver, and the source document.

Stop and get qualified help when

Do not continue troubleshooting if any of these apply:
  • Toner spills or internal parts are hot
  • A drum, transfer belt, or printhead surface is visibly damaged

Official support and model manuals

Use the full model number from the rating label. The manufacturer manual is the deciding reference when codes differ by region or product family.

Frequently asked questions

Will alignment fix missing lines?

Alignment corrects placement; it does not usually restore blocked nozzles or damaged imaging parts.

Why do marks repeat at equal distances?

A rotating roller or drum defect often repeats once per circumference.

Keep diagnosing
