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.
Before the message
What users usually notice first
Messages like this often appear after the printer fails one of its normal startup, supply, or paper-path checks and cannot return to ready state cleanly.
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.
Avoid wrong turns
Common misreads of this message
- -Treating the message like a confirmed failed part instead of a support clue about which system has stopped the printer.
- -Assuming no physical path issue exists just because no full sheet is visible at first glance.
