You sit down to write, uncap your favorite pen, and… nothing. Or worse — a stuttering, skipping line that makes your handwriting look like a seismograph during an earthquake. I’ve been there. With over 200 fountain pens in my collection, I’ve dealt with every flavor of skip imaginable, and I’m here to tell you: skipping is almost always fixable.
This guide walks through the six most common causes of fountain pen skipping, how to diagnose which one is wrecking your writing experience, and exactly what to do about each one.
What Does “Skipping” Actually Mean?
Before we dive in, let’s make sure we’re talking about the same thing. Skipping refers to gaps or breaks in the ink line as you write — moments where the pen moves but no ink comes out. It’s different from hard starts (where the pen won’t start after sitting uncapped) or blobbing (where too much ink flows at once). Skipping happens mid-stroke, which makes it especially frustrating.
The good news: fountain pens are mechanical devices, and mechanical problems have mechanical solutions. Let’s find yours.
Cause 1: Dry Nib or Ink Starvation
This is the most common culprit — and the easiest to fix. If your pen isn’t delivering enough ink to the nib, you’ll get intermittent or consistent skipping.
How to Diagnose
- Skipping is consistent across different papers
- Holding the pen at a lower angle (closer to horizontal) helps temporarily
- The line looks thin and scratchy, not just gappy
- The pen skips from the very first stroke after a fresh fill
How to Fix
Check your ink level first. A nearly empty converter or cartridge will cause starvation. Refill and test again.
Prime the feed. On a converter-filled pen, gently push the converter piston forward a quarter turn to push a small amount of ink into the feed. Don’t overdo it — just enough to wet the channel.
Check for air bubbles in the converter. Sometimes air gets trapped. Pull the converter off (if possible), shake it gently, and reinstall.
Flush and refill. Sometimes dried ink residue in the feed restricts flow. Flush with room-temperature water until it runs clear, then refill with fresh ink.
If you’re using a vintage pen with a sac filler or a piston pen, check that the mechanism is actually drawing ink. On sac pens, the sac can harden over time and fail to create suction.
Cause 2: Misaligned or Too-Tight Tines
The two tines of a nib need to be perfectly aligned — side by side at the same height, with the correct gap between them. Misalignment is a common cause of skipping, especially on new pens or after a drop.
How to Diagnose
- Skipping only happens at certain writing angles
- The pen writes fine when you hold it one way but skips when you rotate it
- Under magnification (10x loupe or phone macro), one tine sits higher than the other
- Tines look pressed together (too tight), reducing the ink channel
How to Fix
Visual inspection first. Hold the nib up to a light source and look straight down the tine gap. You should see a very thin, consistent sliver of light. If the gap disappears on one side, that’s your problem.
For beginners, I strongly recommend a 10x loupe for this inspection — it’s a game-changer for nib work.
Adjusting tines is advanced work. If the tines are slightly too tight, some experienced users will gently press a piece of brass shim between them. If they’re misaligned vertically (one higher), a micromesh pad or careful mechanical adjustment is needed. If you’re not comfortable with this, skip to the “When to Seek Professional Help” section — a nib smith can do this in minutes.
For too-tight tines specifically, writing on a slightly rougher paper (like Clairefontaine) for a few weeks can naturally open the gap through normal use.
Cause 3: A Dirty or Partially Clogged Nib and Feed
Ink is a complex fluid with dyes, pigments (in some inks), humectants, and other additives. Over time, dried ink, paper fibers, and residue can partially block the feed channels. Even invisible deposits can cause skipping.
How to Diagnose
- The pen has gone weeks or months between uses without flushing
- You recently switched inks without fully flushing
- You can see dried ink flakes or visible residue on the nib
- Skipping worsens after the pen has been sitting uncapped for a few minutes
How to Fix
Full flush. Remove the cartridge or converter and run lukewarm water through the pen until it runs completely clear. This can take 10–30 fills and dumps on a heavily clogged pen.
Stubborn clogs. Soak the nib and section in a small glass of water overnight. Most clogs dissolve with time. For iron gall or pigmented ink clogs, a 10:1 water-to-ammonia solution (from a pharmacy) can help break down residue. Never use hot water — it can warp feeds and sections.
Pen flush solution. Products like dedicated pen flush solutions are worth keeping around. They’re safe for all pen materials and effective on most ink types.
Ultrasonic cleaners are effective for seriously clogged feeds, but check your pen’s material compatibility first — some vintage celluloid or acrylic pens shouldn’t go in ultrasonic baths.
Cause 4: Wrong Paper for Your Nib
Not all paper is fountain pen-friendly. Cheap, rough, or highly absorbent paper can cause skipping even when the pen itself is perfectly tuned. Paper fibers literally pull ink off the nib before it can form a proper line.
How to Diagnose
- The pen writes perfectly on one paper but skips constantly on another
- You notice feathering (ink spreading into paper fibers) alongside skipping
- The problem only started when you switched notebooks
- Cheap printer paper, recycled notebooks, or newsprint are involved
How to Fix
Switch to fountain pen-friendly paper. My recommendations:
- Clairefontaine — the gold standard for smooth, ink-friendly paper
- Rhodia — slightly toothy, works beautifully with most nibs
- Tomoe River — ultra-thin but fountain pen-optimized
- Leuchtturm1917 — widely available, very good for fountain pens
If you must use office paper (for work, printing, etc.), a wetter-writing pen with a broader nib will suffer less than a dry fine nib. Consider keeping a separate pen loaded with a wet ink specifically for office paper use.
Cause 5: Ink Problems — Viscosity, Water Content, and Quality
The ink itself can be the villain. Some inks are too dry (low water content, high viscosity), some have additives that gum up feeds over time, and some cheap inks are simply inconsistent in formulation batch to batch.
How to Diagnose
- The same pen writes fine with a different ink
- You’re using a “lubricated” or heavily dyed budget ink
- The ink is old (over 3–5 years) or has been exposed to temperature extremes
- You’re using an iron gall ink in a pen with brass components
- Skipping started after switching to a new bottle of ink
How to Fix
Test with a known-good ink. Flush the pen and fill with a reliable, wet-flowing ink. I recommend:
- Pilot Iroshizuku — consistently wet, well-formulated, forgiving in all pens
- Diamine inks — UK-made, wet writers, great variety
- Waterman Serenity Blue — legendary for being safe and reliable in any pen
Avoid in problem pens: Noodler’s Baystate Blue (pH issues, can be corrosive to some materials), heavily pigmented inks in pens without large feeds, and iron gall inks in vintage pens with sensitive metal components.
Check ink age. Ink doesn’t technically expire, but stored improperly (heat, light, partial evaporation), it can develop mold, become more viscous, or degrade in flow properties. If your ink smells off or has visible particles, replace it.
Cause 6: Nib-to-Feed Gap and Flow Tuning Issues
The nib sits on top of the feed, and the gap between them determines how much ink is delivered to the writing point. If this gap is too small — or if the nib has flexed out of proper position — flow will be restricted and skipping will result.
How to Diagnose
- The pen is new and seems to write “dry” even with a known wet ink
- You attempted flex writing and the pen now skips on normal strokes (a “sprung” nib)
- The nib looks slightly bent or lifted away from the feed
- Pressing the nib slightly into the feed temporarily improves flow
How to Fix
For new dry pens, many nibs just need break-in time. Writing consistently for an hour or two will naturally adjust the nib-to-feed relationship through normal flex and capillary action.
For sprung nibs (overflexed to the point of permanent deformation) — this is serious. The tines have been bent apart beyond recovery. This typically requires professional nib work or replacement.
For subtle flow restriction, gently pulling the nib forward (toward the tip) on the feed by about half a millimeter can improve the gap. This is called “nib adjustment” and is advanced — work slowly, test often.
When to Seek Professional Nib Work
There are situations where the right answer is to hand the pen to a professional. Don’t hesitate to do this — good nib smiths exist specifically because nibs are finicky precision instruments.
Seek professional help when:
- You’ve tried all the above fixes and the pen still skips
- The nib tines are visibly misaligned and you’re not comfortable adjusting them
- The pen was dropped and now skips (possible structural damage)
- The nib is sprung from flex writing
- It’s a valuable pen (vintage, high-end) — don’t experiment
Look for nib smiths at pen shows, or services like those offered by some specialty pen retailers online. A basic nib adjustment typically costs $20–50 and can resurrect a pen you’d otherwise shelve.
Preventive Habits to Keep Your Pen Writing Smoothly
Prevention is far easier than troubleshooting. Here’s what I do to keep my collection writing well:
- Use the pen regularly. A fountain pen used daily almost never develops flow problems. Ink stagnates in pens that sit unused for weeks.
- Flush every 4–6 weeks even if the pen is still writing fine, especially with heavily dyed inks.
- Cap when not in use. Even a few minutes uncapped can dry the nib enough to cause skipping when you return.
- Store horizontally or nib-up. Nib-down storage can cause ink pooling and eventual flow issues.
- Match your ink to your pen. Fine nibs need wetter inks; broad nibs can handle dryer inks more easily.
- Use quality ink. The small price difference between budget ink and a quality bottle from Diamine, Pilot, or Waterman is worth it every time.
Quick Diagnosis Checklist
Before you do anything else, run through this checklist:
- Is the ink level adequate? → Refill
- Does it skip on all papers or just one? → Paper problem
- Does it skip with all inks or just one? → Ink problem
- When did you last flush? → Flush and refill
- Has the pen been dropped? → Inspect tines under magnification
- Is this a new pen or one that recently started skipping? → Different approaches for each
Most skipping issues resolve at step 3 or 4. If you’ve worked through the whole list and the pen still skips, you’re likely looking at a nib alignment issue or a sprung nib that needs professional attention.
Fountain pens reward patience. Every pen I’ve wrestled back from chronic skipping has gone on to become one of my daily writers. The fix is almost always out there — sometimes you just need to work through the checklist methodically.
