What to check first
Step-by-step checks
- 1

Reload plain paper in the cassette and align the side guides with the paper edges.

- 3

Press OK on the printer once the paper is loaded correctly.
Background
What this message usually means
Canon uses support code 1003 on GX1000-series printers when the cassette does not have paper loaded correctly or the paper did not feed as expected. In practice it usually means the paper stack, guides, or cassette loading needs attention before the printer can continue.
Diagnosis
Likely causes
The cassette is empty or the paper stack is not seated correctly.
The paper guides are not aligned with the edges of the paper.
The printer could not pull a sheet cleanly from the cassette.
Service
When service or replacement is more likely
- -Treat 1003 as a paper-loading or feed-start check first, not a hardware failure.
- -If the printer also reports a jam code, clear the jam before retrying 1003.
