36-contact MDR / IEEE 1284C form

A 36-contact Mini Delta Ribbon implementation is documented by 3M for the IEEE 1284C interface and is physically different from the full-size 36-position CHAMP printer form.

Also called MDR 36 IEEE 1284C connector 36-contact MDR Mini Delta Ribbon 36

Sharing a 36-contact count does not make MDR/1284C and CHAMP-36 the same connector.

Look for

Distinguish the compact MDR shell from the larger CHAMP-36 outline and confirm the interface designation in the equipment documentation.

Use the source-backed form or position count only for identification. Resolve ratings, protocol, direction, wiring, cable construction and exact device support from the relevant equipment and component documentation.

Before you connect

What to check

  1. Identify the exact connector family and variant from the equipment or cable documentation.
  2. Keep shape, contact count, protocol, electrical rating and device support as separate facts.
  3. Do not force, rewire or adapt a connector from this recognition record; resolve the remaining requirements first.

Pins & wiring

Pinout

Choose the exact wiring. Pin numbers follow its stated view; a schematic does not establish physical positions. Check your exact device before wiring.

What the status labels mean
Confirmed
Recorded research passes agree within this variant; this is not independent human review or hardware validation.
Single source
Only one underlying document, or one pass, supports this assignment.
Device-specific
Supported for the named equipment or wiring only. Check your device’s manual.
Unverified
Missing or conflicting evidence. Do not wire from this row.
Not connected
The source explicitly says NC, no contact or no pin for this wiring.

  • No HP or other manufacturer 1284-C table was retrieved.
  • The Xerox table gives pins 19-35 only as return pins for pins 1-17; whether they are individually grounded in the printer is not stated.
