What to check first

Step-by-step checks

  1. 1

    Consumable check

    Reload a small stack of clean paper in the source the printer is currently set to use.

    Start with the official recovery step before moving on to parts or deeper servicing.

  2. 2

    Safe first step

    Check the source setting in the print dialog or on the printer before retrying.

  3. 3

    Consumable check

    Square the paper stack and align the guides without pinching the sheets.

Background

What this message usually means

Canon uses support code 1015 when the GX4000 family cannot start a print because the selected paper source is empty, loaded badly, or not ready to feed. It is usually a tray or cassette setup issue rather than a deeper printer fault.

Diagnosis

Likely causes

Most common

The selected paper source is empty.

Common

Paper is loaded badly, curled, or sitting below the pickup point.

Possible

The printer is still expecting a different source than the one you filled.

Service

When service or replacement is more likely

  • -Treat 1015 as a paper-source check first, not a service code.
  • -If another jam code appears with it, clear the jam before chasing the source setting.
