HP Designjet Z2100, Z3100, Z3100ps, Z3200, and Z3200ps Service Manual OEM

• Exact model coverage: Z2100 Q6675A/C/D (24-inch) and Q6677A/C/D (44-inch); Z3100 Q5669A (24-inch) and Q6659A (44-inch); Z3100ps Q5670A (24-inch) and Q6660A (44-inch); Z3200 Q6718A/B (24-inch) and Q6719A/B (44-inch); Z3200ps Q6720A/B (24-inch) and Q6721A/B (44-inch). 444-page PDF, HP Version 11.0, cover-dated June 21, 2011.
• Covers factory front-panel diagnostic tests for the Scan Axis—PRS, scan-axis servosystem, Star Wheel Lifter, and Cutter—plus Paper Drive, Electronics Module/PSU, Carriage Assembly, sensors, Color Sensor ESP, Ink Delivery System, and Service Station/Primer Motor hardware.
• Decodes the hexadecimal XX.YZ and XX.n:YZ.m system-error structure, with subsystem tables and full fault-isolation paths for PCAs, formatter/HDD, power supply, trailing cable, scan- and media-axis motors, Pen-to-Paper Space (PPS), ink stations, sensors, and calibration faults.
• Explains the Service Image Quality Diagnostic Print and Advanced Diagnostic plots used to assess printhead reliability, color-to-color and bidirectional alignment, paper advance, nozzle health, Force Drop Detection, banding, graininess, bronzing, scuffing, and media-contact marks.
• Maps scan-axis, paper-advance, drop-detector, line-sensor, Carriage PCA, Color Sensor ESP, service-station, and printhead-alignment calibrations through the post-repair Service Calibration Matrix. Service utilities cover Purge Tubes, Turn Drive Roller, Set SN, Error 71:19 Recovery, diagnostic printing, and life-counter resets.
• Removal and installation sections address the carriage, trailing cable, encoder strip, belt, scan-axis motor, ink supply stations and tubes, service station, formatter/HDD, Main PCA/PSU, media-advance hardware, pinchwheels, starwheels, and cutter, backed by exploded parts views and service-tool references.

Model, Width, and Revision Differences

The parts chapter is organized by printer model, width, and hardware revision rather than treating the whole family as interchangeable. It flags Rev. A/B/C/D-only components and separates 24-inch from 44-inch encoder strips, belts, trailing cables, ink tubes, carriage assemblies, paper-path hardware, and PMK1 contents.

An important electrical split is documented in the parts tables. Z2100 Rev. D and Z3200/Z3200ps Rev. B use a formatter without HDD plus a separate hard disk. Formatter-with-HDD assemblies are listed for Z2100 Rev. C, Z3100/Z3100ps, and Z3200/Z3200ps Rev. A.

Media-path changes are called out just as clearly. The actuator-equipped starwheel assembly applies to Z2100/Z3100/Z3100ps hardware except Z2100 Revision C. The Rubber Pinchwheel Kit is a retrofit for Z2100/Z3100/Z3100ps, while Z3200-series machines already use rubber pinchwheels. Some printers were built without an aerosol fan, so the manual has technicians verify the hardware before running that test. These distinctions matter before repair parts are ordered or a diagnostic path is selected.

Diagnostics, Repair Procedures, and Service Data

Beyond component-level diagnostics, the manual covers clipped or partial output, missing objects, EMF-spooled files, page rotation, custom page sizes, and long-image limitations in Adobe Photoshop, Acrobat, PowerPoint, and Mac versions of Photoshop, Illustrator, and InDesign. The image-quality chapters separate printer faults from media, RIP, driver, alignment, paper-advance, and nozzle issues instead of treating every defect as a failed printhead.

Named technical illustrations include the Primer schematic, Electronic layout, Main electronics and cabling, Ink supply station schematic, Carriage Assembly exploded view, and front/rear Paper Path Assembly views. Tool references identify the Tool Kit Q6683-67001, Flex Contacts Cleaning Tool Q5669-60690, Media Driver Tool Kit Q6675-67018, Pinchwheel Insertion Tool Q6687-60084, and Lubrification Kit Q5669-60692. The named electrical diagrams focus on assembly layout and cabling rather than board-level component repair.

Preventive-maintenance coverage links life counters to PMK1, PMK2, and PMK3. It addresses carriage lubrication, drive-roller and overdrive cleaning, belt storage, and counter resets after kit or component replacement. PMK1 is divided by printer family and width; PMK2 Q6718-67026 and PMK3 Q5669-60722 apply across the listed 24- and 44-inch units.

One repair trap is stated repeatedly: never replace the Formatter and PrintMech PCA at the same time. The printer must fully initialize after the first replacement to avoid the 71:19/default-serial-number condition. Printheads can also be damaged by angled insertion or by touching or wiping the nozzle face.

HP states that the procedures are for qualified service personnel. During service tests, the cover sensors are disabled, so opening the window will not stop a moving carriage; power isolation and ESD precautions are required before repair work on the electronic assemblies. Routine operation is referred to the separate User and Quick Reference Guides.
