Direct answer
A failure immediately after a known change should be checked for new defaults, stale pairing, power sequencing or compatibility before factory recovery. For borderless photo expansion, first print a draft marked at every edge and inspect the preview crop.
What this covers
- borderless photo expansion with this exact failure state
- Diagnosis across photo/paper aspect ratio versus driver expansion, orientation and media size
- Customer-accessible observation, settings and external components
What it does not cover
- ×A displayed manufacturer error code with a different documented meaning
- ×Live electrical, sealed-system, internal battery-cell or gas repair
- ×A claim that every model exposes identical controls
Capture the exact failure state
ReversibleRecord the change, version, outage time or newly connected hardware and the last known working state. Expected behavior: cover the paper edge with controlled overscan and predictable crop.
Isolate the component boundary
ReversiblePrint a draft marked at every edge and inspect the preview crop. Remove or roll back only the reversible change, or test the previous direct path. Boundary to separate: photo/paper aspect ratio versus driver expansion, orientation and media size.
Correct only the proven cause
ReversibleReduce expansion, reposition the crop or use borders to preserve the whole image. Reapply compatible settings, update both endpoints or replace the incompatible new path.
Verify and stop safely
ReversibleRestart twice and confirm the feature remains stable with the intended change present. Do not modify the original destructively before a successful proof.

Common follow-ups
What should I check first when borderless photo expansion has this problem?+
Print a draft marked at every edge and inspect the preview crop.
Why not factory-reset immediately?+
The useful boundary is photo/paper aspect ratio versus driver expansion, orientation and media size. A reset can erase state without proving which side failed.
When should I stop troubleshooting?+
do not modify the original destructively before a successful proof.
