Reliable Parts for the HP Designjet 4000 and 4500 Series

The Designjet 4000 and Designjet 4500 are built for high-volume production, but heavy use takes its toll. Printheads clog, tube systems develop leaks, and electronics wear out over time. Rather than replacing an entire plotter, a targeted repair restores full performance for far less. We stock parts across the whole line, so HP DJ 4520 owners and HP 4000n Designjet users alike can find the right fit.

Popular categories our customers rely on include:

  • Printheads and ink delivery: HP 90 printheads, ink cartridges, tube systems, and priming tools
  • Electronics: Formatter boards, power supplies, hard drives, carriage PCAs, and memory
  • Mechanical parts: Carriages, scan-axis motors, cutters, spindles, and service stations
  • Sensors and fans: Media sensors, line sensors, drop detectors, and cooling fans

Because LPS owns many of the original injection molds, we manufacture high-quality direct-replacement parts and rebuild critical assemblies you won't find anywhere else.

Why Buy HP 4000 Designjet Parts From LPS?

  • Decades of dedicated HP Designjet expertise as a former Authorized Service Provider
  • Worldwide shipping to service companies and self-repair users alike
  • Hard-to-find parts for discontinued and legacy plotters
  • Real technical support from people who know these machines inside and out
