Volume 1A - HT-0604IA Control Board & Head
Mapping
Focused retrieval module - authoritative facts only
Purpose
This short module corrects one retrieval failure: identifying the documented control-board labels and the
active head connectors for the PO-TRY HT-0604IA 4-head printer. Do not supplement these facts with
plausible printer hardware from general knowledge.

1. Source control-board diagram

Charlie PO-TRY Volume 1A - HT-0604IA Control Board & Head Mapping Page 2
Source manual page 11: the card description labels the Ethernet port, Decoders, Anti-Collision, Peripheral Comm, Power Source, and
Head 1 through Head 6 connector positions.

2. Exact documented labels
Category Exact documented label(s)
Communication Ethernet port; Peripheral Comm
Board functions/interfaces Decoders; Anti-Collision; Power Source
Head connector positions Head 1; Head 4; Head 2; Head 5; Head 6; Head 3
HT-0604IA 4-head mapping
Active connectors: Head 1 + Head 2 + Head 3 + Head 4.
The manual separately states: “The 4-head DTF Printer uses Head 1, 2, 3 and 4.” Head 5 and Head 6 exist
on the illustrated board because the board/manual covers multiple printer configurations; they are not part of
the documented 4-head mapping.
Documentation boundary - do not guess
Exact PCB manufacturer: NOT SPECIFIED
Exact PCB/model or part number: NOT SPECIFIED
PCB revision: NOT SPECIFIED
Do not invent CPU, memory, USB, PCL, connector pin counts, connector types, or a “standard board”
description. Those items are not established by this source section.

3. Retrieval rule for Charlie
When asked about this board, retrieve the exact source labels first. If the requested hardware detail is absent
from this module/manual, answer NOT SPECIFIED rather than filling the gap from general printer knowledge.

4. Micro-certification test
Answer from this module only. Do not expose the training-volume name unless explicitly asked.

1. Which numbered Head connectors are used by the HT-0604IA 4-head configuration?

2. Name the two documented communication-related labels shown on the board diagram.

3. Name the remaining documented board-function labels besides the head connectors.

4. Does the source specify the exact PCB manufacturer, model/part number, or revision?

5. True or false: because Head 5 and Head 6 are visible on the board diagram, the HT-0604IA uses
all six connectors.

6. A user asks whether this board has a USB interface and a CPU shown in the diagram. What
should Charlie say from this source alone?
Answer key
Q Expected answer
1 Head 1, Head 2, Head 3 and Head 4.
2 Ethernet port; Peripheral Comm.
3 Decoders; Anti-Collision; Power Source.
4 No. All are NOT SPECIFIED in the source.
5 False. The documented 4-head mapping uses Head 1-4.
6 Those details are not specified/shown by this source; do not infer them.
Pass standard
6/6 for the focused retrieval test. Any invented board component or incorrect head mapping is an automatic
retraining flag.
