HP DesignJet 5000 / 5000PS Service Manual (411 P.)

Essential Specification Reference Manual: Printer HP DesignJet 5000 / 5000PS Service Manual (411 P.) Technical-Repository

Diagnostic-Area: HP DesignJet 5000 & 5000PS Series (42" & 60" Models: C6090A/V, C6095A/V, C6091A/V, C6096A/V) — 2000–2001 // Operational-Framework: Mechanical Industrial Reference / DesignJet 5000 Series Segment // Machine-Range: Large-format printing systems with six-color ink configuration and modular service architecture.

Repair data is categorized into troubleshooting system error codes, cataloging service tests for scan-axis motor assemblies, detailing calibration procedures for printhead alignment, documenting ink supply station diagnostics, and addressing preventive maintenance requirements for carriage bushing systems.

Consistently establishing the technical framework for service personnel, the manual documents torque specifications for the paper-axis motor assembly to ensure proper bearing preload accuracy. Adjustment procedures are detailed for the carriage height calibration methodology, requiring the specialized carriage height tool included with replacement platen assemblies. The encoder strip installation protocol addresses proper sensor alignment across the 42-inch and 60-inch model configurations, with distinct trailing cable routing requirements for each printer width specification.

Technical notes are provided for the modular ink delivery system architecture, encompassing the ink supply station (ISS), air pressurization system (APS), and leak detection subsystem (LDS). The document catalogs six printhead positions with corresponding cleaner assemblies, each requiring specific insertion and recovery procedures when status codes indicate maintenance intervals. Firmware initialization sequences are documented across seven diagnostic phases, from memory configuration validation through IO device recognition and hard disk drive spin-up protocols.

Timing procedures are documented for the service station calibration sequence, which integrates line sensor to black printhead positioning, drop detector accuracy verification, and primer arm movement cycles. The manual addresses the relationship between altitude compensation settings and vacuum fan performance, noting that operation above 2000 meters requires configuration adjustments to maintain proper media hold-down pressure during high-density print operations.

Quality checks are addressed for the diagnostic print interpretation process, which evaluates primary color banding patterns, bidirectional alignment accuracy, vertical line straightness, and individual nozzle functionality across the 512-nozzle array in each printhead assembly. The nozzle test section documents acceptable defect thresholds and recovery procedures, distinguishing between automatic printhead servicing routines and manual intervention requirements when status transitions from OK to RECOVER or REPLACE designations.

The electrical system section documents the power supply unit connections to the main PCA, ISS PCA, and carriage assembly, with connector position references (P9, P10, P12, P15, P19, P23, P24, P27, P29, P30) mapped throughout the electronics module layout. Methodical cable routing protocols prevent interference with mechanical assemblies during carriage movement across the encoder strip span, particularly critical for the trailing cable installation that requires precise length adjustment between left and right retention clips.
