| Specification | Component Coverage | Documentation Status |
|---|---|---|
| Document Overview | Service procedures for D/A1-size and E/A0-size plotter configurations | Complete technical specifications provided |
| System Categories | Electronics enclosure, carriage assembly, media path mechanisms, service station components | Documented across Chapters 5-6 |
| Reference Topics | Calibration protocols (accuracy, line sensor, drop detect), troubleshooting diagnostics, part replacement procedures | See Chapters 7-8 for complete procedures |
Technical units are distributed across Installation and Configuration procedures, Functional Overview architecture, Removal and Replacement protocols, Calibrations methodology, and Troubleshooting diagnostics encompassing preventive maintenance schedules and service test sequences.
Assembly instructions are detailed for electronics-enclosure configurations where the main PCA coordinates carriage-axis movement through Y-axis servo control, while media-axis operations utilize X-axis motor assemblies driving the platen roller mechanism. Hydraulic schematics are included for power-supply voltage regulation systems managing 100–264 V ac input ranges converting to +42V, +24V, +5V, and -5V dc outputs for motor drivers and cartridge electronics.
Steering component information is provided for bi-directional print modes utilizing carriage speeds up to 18.33 inches per second across swath widths ranging 0.32 to 0.48 inches depending on resolution and quality settings. The document catalogs four primary cartridge configurations (black 51645A, cyan 51644C, magenta 51644M, yellow 51644Y) with nozzle checkout patterns and drop-detector calibration sequences.
Inspection guidelines are provided for service station assemblies incorporating primer mechanisms, bail stepper motors, and wiper blade systems requiring replacement after 20,000 plot cycles or 4,500,000 carriage movements. Alignment specifications are included for pen-to-pen positioning tolerances maintained within 3.33 mils on film media to prevent banding artifacts in multi-pass rendering modes.
The manual documents torque specifications for fastener assemblies to ensure proper mounting integrity across leg assemblies, electronics enclosure attachment points, and carriage belt tension mechanisms throughout the plotter framework.
