- !136A keeps returning on fresh paper with a clear path.
- !The transport path makes abnormal noise or stalls during every print.
What to check first
Step-by-step checks
- 1
Consumable check
Remove any paper from the path and inspect the output area for scraps.
Start with the official recovery step before moving on to parts or deeper servicing.
- 2
Escalate
Retry with fresh, flat paper that matches Canon's supported media guidance.
- 3
Safe first step
Restart the printer once after clearing the path.
Background
What this message usually means
Canon uses support code 136A on GX4000-series printers when the paper path or output movement does not look right. It usually behaves like a feed-transport warning that needs a path check before you continue printing.
Diagnosis
Likely causes
Paper moved badly through the output path.
A small obstruction or scrap is affecting transport.
The printer is working with curled, damp, or unsupported media.
Service
When service or replacement is more likely
- -This is usually still a paper-handling issue before it becomes a service case.
- -If a more specific jam code appears afterward, follow that one first.
