Direct answer
A printer problem limited to one sender, document, tray or media type should be repaired at that boundary, not with a factory reset. 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
ReversibleName the failing sender, document, tray or paper type and one combination that still prints correctly. 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. Change only the sender, job, tray, media or connection while keeping the printer state unchanged. 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. Repair the isolated queue, document, tray setup, media selection or connection.
Verify and stop safely
ReversiblePrint the same controlled test from both the failing and known-working contexts. 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.
