HMS 0700-2000-0002-0002: The AMS Slot Is Empty

HMS 0700-2000-0002-0002 means the AMS A slot 1 is empty. If you took the reel out, that is correct and you can ignore it. If a reel is physically sitting there, the slot cannot see it, and that is worth ten minutes.
An empty slot and a slot that cannot see its filament produce the same message, so start by deciding which one you have.
Where to buy
Feed the filament in far enough
The slot only acknowledges filament once the end passes the feed-in sensor, and a reel resting in place with the end an inch short does not count. Push it in until the slot takes over and pulls. The loading sequence is described in printers with an AMS.
Use refill filament to keep slots full
Spool-free refills are cheaper per kilo and stack flat, which makes keeping a backup of each colour practical rather than theoretical. They need a reusable hub, which most people printing multi-material already own.
Keep spare reels sealed and ready
Vacuum storage bags let you keep a loadable reel of each colour on the shelf without it going damp while it waits. A slot stays empty far longer when the only spare is a reel you no longer trust.
Store the rest where you can reach them
A spool rack keeps the reels you rotate through in sight, and a slot stays empty far longer when refilling it means digging through a cupboard.
How HMS 0700-2000-0002-0002 differs from a run-out
A reel that finished mid-job reports HMS 0700-2000-0002-0001. Empty means the slot never had filament in it as far as the sensor is concerned.
When the slot cannot see a reel that is there
If the filament is in and the slot still says empty, suspect the feed-in sensor rather than the message. Identification problems look similar — see HMS 0700-2000-0001-0083 — and alternatives to the unit are in AMS alternatives.
HMS 0700-2000-0002-0002 FAQ
Can I ignore it?
Yes, if you emptied the slot on purpose.
How far in should the filament go?
Until the slot grips and pulls it in by itself.
Do I need a spool for refill filament?
Yes, a reusable hub. The refill itself has none.
Why does it report per slot?
Each slot has its own sensors and reports independently.
