The Printhead height setting affects printing quality.
Specifying a low Printhead height makes images clearer and enhances printing quality but may cause paper to rub
against the Printhead.
On the other hand, specifying a high Printhead height will prevent paper from rubbing against the Printhead but
may reduce the printing quality.
Important
•
Paper rubbing against or becoming caught on the Printhead may jam or result in printed documents that are
soiled.
Note
•
Raise or lower the printhead, depending on the nature of the problem.
