How to fill the Onoto Scholar

Unscrew the piston knob at the back of the pen, submerge the nib fully in a bottle of ink, and slowly turn the knob counter-clockwise then clockwise to draw ink in. Piston fillers hold significantly more ink than a standard cartridge — often enough for several weeks of regular writing — at the cost of being limited to bottled ink only.

Choosing a nib size

Nib size determines line width, not writing pressure — fountain pens are meant to glide, never press. Extra-fine (EF) suits small, dense handwriting and thin paper; fine (F) is the most broadly recommended default; medium (M) shows more ink character and shading; broad (B) and stub grinds favor bold, expressive strokes and calligraphy-adjacent writing. The Scholar's gold nib will also flex slightly with pressure, giving line variation that a steel nib of the same size won't produce.

Keeping it clean

Because Onoto Scholar holds a larger ink reserve, a full flush every 4–6 weeks (or whenever you switch colors) keeps the feed running cleanly. Inktend's cleaning reminder is tuned to a 21-day baseline and adjusts naturally to how often you actually refill.

Pairing inks with the Scholar

High-capacity fillers like this one are the natural home for sheening and shading inks; you'll actually see the color develop across a full page instead of running out mid-paragraph.
