After prolonged use, the iAuto’s paper roller may wear down, causing paper or cards to slip or jam. This replacement roller is specially designed for iAuto machines, easy to install, and restores optimal paper feeding performance. Under normal use, we recommend replacing it approximately once a year to ensure stable and efficient operation.

We run a mid-sized company in the D2C space and bought the Uunatek iAuto Handwriting Robot primarily to test whether handwritten customer communication could move the needle for us.
Short answer: it did.
What we like (Pros)
The biggest impact for us was customer loyalty. Handwritten notes simply feel different. They cut through the noise of emails and automated flows. We used the robot for targeted follow-up letters, especially review requests — and saw about a 20% increase in review submissions compared to our previous process. Pro Tipp: If you use a stamp instead of a printed code the likelihood of the customer to open the letter is increased!
It made our brand feel more human and intentional, even though the process is automated behind the scenes.
The machine itself feels solid and well-built. It doesn’t feel like a gimmicky desktop gadget. It runs reliably and gives a professional output.
You're not locked into proprietary pens. We tested different fineliners, ballpoints, and even slightly thicker markers depending on the paper stock. That flexibility makes a big difference if you care about brand aesthetics.
There’s a CURL API interface. It’s definitely more for professionals, but it’s not impossible to work with. If you’re comfortable with basic API integrations, you can automate things quite deeply (e.g., connecting it to order triggers or CRM exports).
For us, that’s where the real power lies.
What could be better (Cons)
1. The GUI software feels outdated
The main downside: the graphical software feels a bit old-school. It works, but the UX/UI could definitely use a refresh. It’s functional, not beautiful.
If you’re expecting a super modern SaaS-style interface, you might be slightly disappointed.
Final Thoughts:
If you're just looking for a novelty device, this might be overkill.
But if you're running a business and thinking seriously about offline customer touchpoints in a digital world, this thing is extremely interesting.
For us, it paid off — especially in review generation and perceived brand value.
Happy to answer questions if anyone is considering it.
Setting up and installing was very straightforward. Was working with A3 plotters from before, but the change in scale makes an order of magnitude in differences. Very precise, easy to setup drawing material with the inkscape extension. If you have available space (had to reconfigure my whole studio due its size) I can highly recommend this drawing machine.
My first pen plotter the Uuna Tek H A3. I settled on this make and model after watching many videos on YouTube. Uuna Tek consistently came out looking the best so I took the plunge and pressed the buy it now button. A week later I had a large box delivered! Opening the box, it's clear the machine was well packed to withstand shipping. A "hand written" thank you card was a nice touch. Assembly was simple and straightforward. The machine is nicely designed and definitely has a quality feel to it. The software was easy to install, I used the inkscape download (with plugins pre-installed) from the Uuna Tek website. All very straightforward and simple! I've attached a couple of my first prints. I'm absolutely delighted with the machine and the quality of the plots it produces. If you, like I was, are initialising hesitating to press "buy it now" - then don't. Press that button - you won't regret it! Regards to you all from a very wet UK.
I purchased this plotter because previously I bought a Silhouette Cameo 4 Pro. That worked but it made a lot of noise and it was very hard to align multiple layers.
This plotter however solved both these issues for me. It is quiet enough to have it running in my room while my son is sleeping in his room next to it. So that's really a big plus.
Also aligning it and doing multiple layers was super easy.
Mounting it took me about 20 minutes. Which was also very easy.
All in all couldn't be more happier with this purchase.
May someday get the A0 version even.
I am absolutely loving my UUNA TEK iDraw H A3 Pen Plotter! I have been using it every single day since I got it. One of the best things about it was the setup process. It was incredibly easy to assemble and get running right out of the box. The instructions were clear, and I didn't run into any issues at all.
I'm attaching a few pictures of the projects I've created with this plotter so far. It's a fantastic tool and I highly recommend it!
