• Covers the 2009 HP Designjet T1100, T1100ps, T610, T1120, and T1120ps large-format printer series.
• Original OEM publication (Version 6, March 19, 2009) spanning 490 pages.
• Features factory-level diagnostic print samples, maintenance flow charts, and specific error code lookups.
• Details troubleshooting logic for resolving complex system errors like 79:04 and 81:YZ in the formatter and print-mechanics modules.

Documented Subsystems and Diagnostics

This manual delivers a detailed breakdown of the T-series printer architecture. It starts with factory-level diagnostic procedures designed to isolate system error codes quickly on the shop floor. You will find specific removal and installation routines for critical modules, including the carriage assembly, service station, and formatter.

Preventative maintenance schedules and media-handling corrections are fully mapped out. Content ranges from basic ink supply troubleshooting and printhead replacement protocols to advanced board-level diagnostics targeting the PrintMech PCA, hard disk drive, and network interface cards.

Specifications and Calibration Details

Hardware configurations detail 69 ml and 130 ml ink cartridge capacities, alongside precise part numbers for the 24-inch and 44-inch chassis builds. The documentation outlines multi-stage printhead alignment protocols and media advance tolerances necessary to keep nozzle health within strict performance limits.

Furthermore, it provides deep electrical diagnostics for formatter LEDs, power supply units, and carriage-to-mainboard communication paths. Users can cross-reference hardware and firmware faults against the included error tables to formulate an accurate repair strategy. Since handling formatter boards and power supplies involves electrical hazards, always verify the machine is fully disconnected from power before inspecting internal routing or conducting board-level continuity tests.
