Editing Schneider DMP3000 Service Manual

The '''''Kundendienst-Handbuch / Service Manual DMP 3000''''' is Schneider's service manual for the DMP 3000 dot-matrix printer, Ident-Nr. 33 624. The footer code is HDS 60259/1500/04/87. It has 12 pages, with the parts lists in German and English side by side, and the scan has a text layer. It covers the DMP 3000 only, and unlike Amstrad's combined [[Amstrad DMP2000 / DMP3000 / DMP4000 Service Manual|DMP2000/3000/4000 manual]] it has a full electrical parts list.

== Contents ==
* p. 1: cover
* p. 2: cabinet parts list (Ersatzteilliste)
* p. 3: cabinet drawing
* p. 4: printer mechanism drawing
* p. 5: mechanism parts list
* pp. 6–7: circuit diagram
* p. 8: wiring diagram
* p. 9: main PCB (Hauptplatine), component side and track side
* p. 10: electrical parts list: resistors, capacitors, diodes, transistors and ICs
* p. 11: miscellaneous parts: mains filter coil, fuses, DIP switches, tact switches, Centronics socket
* p. 12: technical data (in German), DIP-switch table and Centronics interface pinout

Each parts list gives Schneider's order number (Best.-Nr.), the description in German and English, a part number (Teile-Nr.) and the circuit reference.

The electrolytics are all specified as 105 °C parts. The fuses on p. 11 are F1, T3.15 A 250 V, and F2, T315 mA 250 V.

The value of the safety capacitors C32 and C33 is printed two ways: the German column reads "0,0022 µF/250V" and the English column "0.022/250V".

The interface table gives a +5 V output on pin 18, rated at 50 mA maximum, and on pin 35. The DIP-switch table covers DS1-1 to DS1-8 and DS2-1 to DS2-10, with the OFF and ON meaning of each, including page length, paper-end detection, buffer mode and the beeper; DS2-9 and DS2-10 are marked "ohne Bedeutung" (no function).

== What it does not contain ==
There is no fault-finding table, adjustment procedure or maintenance schedule.
