Quick answer
5B00 means the printer has entered a repair-required error state. Match the exact TS8300-series model, stop the job and follow Canon's documented branch once.
Safety first
Stop and check this first
- Stop immediately for smoke, burning smell, liquid inside the printer, a damaged power cable or repeated electrical tripping. Disconnect only if it is safe to reach the plug; never continue testing an unsafe printer.
Safe checks you can perform
- Preserve the exact failure branch
- Stop without applying an unofficial reset

What a technician must be able to justify
A technician is coming
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Measured Canon service handoff for 5B00
What they doProvide the exact model, serial number, 5B00 message, job stage and the result of “Stop without applying an unofficial reset”. Ask the technician to reproduce the branch “the printer has entered a repair-required error state” against the exact service information and record the failed observation or measurement before quoting a part.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Preserve the exact failure branch
Photograph 5B00, the full touch-screen message and the exact TS8300 model. Note the paper source, active job and whether the code appeared before movement, during feed or after printing. The code narrows the branch to “the printer has entered a repair-required error state”; it does not identify a replacement part.
Stop immediately for smoke, burning smell, liquid inside the printer, a damaged power cable or repeated electrical tripping. Disconnect only if it is safe to reach the plug; never continue testing an unsafe printer.

Stop without applying an unofficial reset
Photograph 5B00 and the exact model, cancel the job and turn the printer off normally. Canon's page sends this code directly to service. Do not enter service mode, reset counters, open the chassis or assume an absorber part from third-party advice; the public page does not authorize those actions.
Stop immediately for smoke, burning smell, liquid inside the printer, a damaged power cable or repeated electrical tripping. Disconnect only if it is safe to reach the plug; never continue testing an unsafe printer.

Evidence: Canon PIXMA TS8300 support code 5B00
- 5B00 persists after the documented actionPossible
If 5B00 returns once the visible condition has been corrected, the safe external branch is exhausted. The recurrence proves only that the documented action did not resolve this branch; the display alone cannot select or confirm an internal component.
