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 DMP2000/3000/4000 manual it has a full electrical parts list.

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
[edit | edit source]There is no fault-finding table, adjustment procedure or maintenance schedule.
