[Symptom]
text ([a], [b])/thin line ([c], [d])/shading areas in black may come out too light.
No problem occurs in the photographic-toned image [f].
[Cause]
This machine reliably reproduces drawing data of small text and thin line.
When the fonts for small text and thin line are printed, they tend to appear thinner/fainter than those printed from other models.
This results in the symptom.
