What a technician must be able to justify
Technician visit
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 2123
What they doProvide the exact model, serial number, 2123 message, job stage and the result of “Make the displayed registration match the physical paper”. Ask the technician to reproduce the branch “rear-tray paper information is incomplete or the paper changed while power was off” 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 2123, 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 “rear-tray paper information is incomplete or the paper changed while power was off”; it does not identify a replacement part.

Make the displayed registration match the physical paper
Read the size/type shown on the touch screen and compare it with the paper actually in the rear tray. Select Yes only for an exact match. Otherwise select Change and register the physical stock. The decision is complete when the display and tray agree; repeatedly selecting Yes on a mismatch only suppresses evidence. If 2123 returns after this attempt, stop and use the official Canon reference below. Do not repeat the procedure.

What it means
Canon's official TS8300-series manual says support code 2123 means rear-tray paper information is incomplete or the paper changed while power was off. This applies to the documented TS8320, TS8340, TS8350/51/52, TS8360, TS8370 and TS8390/91/92 family, not every Canon printer.

Evidence: Canon PIXMA TS8300 support code 2123
- 2123 persists after the documented actionPossible
If 2123 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.
