Amstrad DMP2000 / DMP3000 / DMP4000 Service Manual

The DMP2000 / DMP3000 / DMP4000 Printer Service Manual is Amstrad's combined service manual for three dot-matrix printers, 22 pages, with a text layer and searchable. Its own cover note reads "DMP2000/3000 section only. For DMP4000 see pages 13 onwards."

What it settles

The technical specification prints the DMP2000 and DMP3000 side by side, which is the quickest way to tell two similar machines apart:

• Both are impact dot matrix. DMP2000: 105 cps maximum; DMP3000: 105 cps normal and 52 cps double width.
• DMP2000 printing characteristics 9 × 9 normal, 9 × 10 expanded, 9 × chosen amount for 9-pin bit image, with 96 ASCII characters plus international sets. DMP3000 adds italics and an 8 × chosen amount bit-image mode, with a normal character size of 2.1 mm wide × 2.55 mm high.
• Print sizes are the same on both: standard (pica) 10 cpi / 80 cpl, mini (elite) 12 cpi / 96 cpl, double-width standard 5 cpi / 40 cpl and double-width mini 6 cpi / 48 cpl. Condensed (17 cpi / 137 cpl) and double-width condensed (8.5 cpi / 68 cpl) are listed for the DMP2000 only.

Pages 6–7 carry a printer mechanism parts list, and page 12 an electrical parts list — the component-level sources for these machines.

What this manual does not contain

• The DMP4000 section is short. Eight pages (13–20) against twelve for the DMP2000/3000, and the cover note treats it as an appendix rather than an equal section.
• No troubleshooting or fault-symptom tables of the kind the DMP1 manual carries.
• No alignment or adjustment procedures.
• Nothing on the DMP1 or the LQ3500.

The other DMP2000 manual

Amstrad DMP2000 Printer Service Manual (standalone) is a genuinely different document — a 12-page, DMP2000-only manual, cover price £5.00, with its own contents including a printer mechanical drawing and parts list at pages 8–9 and a different arrangement of the circuit and wiring diagrams. The two are not duplicates, and between them they are the fullest coverage of the DMP2000 available here.
