Adonit Jot not working properly?

Adonit claims that only 1% of their capacitive touch disc tip styluses have issues with skipping and contact. I've found that to be wholly inaccurate. Every Jot I have has had an issue.

The problem is likely a design flaw that they don't want to admit to. Capacitive touch styluses essentially trick the iPad into recognizing it as your finger. The way the iPad screen works is somewhat difficult to explain, but essentially, a conductive surface of about 6mm is what the iPad looks for.

Instead of the typical soft rubber tips, some styli use discs, like the Adonit Jot series: Mini, Pro, Flip, Touch. Other manufacturers use disc tips as well. The disc is plastic with a metal piece that touches a metal pen, with a small enough surface area to offer precision, and just barely large enough to be detected. In theory, this is great. In practice, well...

If your Jot isn't working properly, Adonit may send you new tips or a new pen. But you will probably have the same problem again.

The most common issue is skipping, where a continuous line drawn on the screen with the capacitive stylus, in this case Jot Pro, is broken into segments and dots. In addition, the stylus may not start a line where you intend, appearing several millimeters after you thought you were touching the screen.

Fear not. There's a cheap fix!

Conductive grease or thermal compound will most likely solve your problem. I improved my HEX3 Jaja the same way. I ordered Arctic Silver Ceramique 2 from Amazon. [Order yours! There's also a link in the sidebar. I get a small credit if you use it. Thanks!] Another brand may work just fine; electronics stores should carry it, places like Radio Shack — or a store that sells motherboards and processors should you want to pick it up at a retail location. Other Jot owners have tried this as well; I actually found this solution on the Adonit forums.

Step 1: Simply remove the disc from the Jot.

Adonit has a guide to replace a disc. Make sure the disc is clean!

Step 2: Place a dab of thermal compound paste on the disc.

You only need a small amount. Just take a tiny dab and put it in the hole where the Jot's ball tip inserts into the disc. You can also rub a thin coating around the ball tip. Afterward, reinsert, and make sure the disc is clean.

And that's it! Your stylus should work 100% better!

I hope I just helped you save your $25-100 stylus, and/or a month of dealing with customer service getting nowhere. I'm sure many frustrated Jot owners have given up on their styluses, so let them know about this!

Problems with Hex3 Jaja pressure sensitive stylus?

The Jaja tips are slightly different. The disc is attached to a 0.7mm metal rod that inserts into the Jaja stylus (or any 0.7mm mechanical pencil). From my experience, it isn't that responsive, and requires uncomfortable, firm pressure and a near vertical angle to work properly.

 

You can improve the Jaja significantly by adding a bit of thermal compound. Remove the tip, and place the disc on a flat surface. Rotate the metal rod to the side, and put a small amount of paste onto the ball. Next, twist the rod and rotate it in circles, spreading the paste around the part of the tip that holds the rod.

 

The thermal compound will improve the conductivity of the tip, and your capacitive touch stylus should now work with very little pressure!

Hopefully this helps! Let me know.
