Greetings.
I am a man in a suit who has fallen into the world of Minecraft.
Last time, I built a cartographer workshop in the castle town, and a villager became a cartographer.
To make paper easier to prepare, I am building a sugar cane harvester beside the workshop this time.
I will use observers and pistons, then test the path that carries broken sugar cane into a chest.
Building a sugar cane harvester beside the workshop
The finished machine is a long structure enclosed with glass.

Inside, I plant sugar cane in eight positions and line up pistons behind it.
From the workshop roof, the relationship between the machine and the building is easy to see.

This takes the small plot from the previous episode one step further by adding a collection system for paper materials to the castle town.
Connecting the observers, pistons, and collection path
I place one observer at each end of the machine, for a total of two.

They are positioned so that a change at the height of the third sugar cane block sends a signal to the pistons.
I line up eight pistons facing the second level of the sugar cane.

Redstone wiring connects the observers to the row of pistons.

I use Yuzukaki’s automatic sugar cane harvester as a design reference, adapting the layout to the space beside the workshop.
Below the plants, I arrange hopper minecarts and route the fallen sugar cane through a hopper into the chest.

Minecraft’s official hopper guide explains that a hopper can collect items falling from above and transfer them into a connected container.
In this machine, I also confirm that items move from the hopper into the collection chest.
Testing the machine, making paper, and trading with the cartographer
When I extend the sugar cane to the third level by hand for a test, the observers react, the pistons move, and I confirm that the broken sugar cane travels through the hopper minecarts and hopper into the chest.

All 11 pieces in the chest come from tests triggered by placing the third level of sugar cane by hand.
I have not yet observed the complete sequence from natural growth through breaking and collection.
With the collection path confirmed, I place three pieces of sugar cane in a horizontal row on the crafting table.

As shown in Minecraft’s official paper guide, three pieces of sugar cane make three pieces of paper.
I take the paper to the workshop and open the cartographer’s trading screen.

In this trade, I hand over 24 paper and receive one emerald.
I have now tested the sugar cane collection path, made paper, and completed a trade with the cartographer.
I will continue watching for a harvest triggered by natural growth while putting the machine to use for the castle town’s paper supply.
That is all for this time.
Greetings.
