Symptoms this fixes

A failing ink tube system often shows up as a leak rather than an error code. Look for:

• Ink leaking from the ink tube assembly
• Ink dripping or spilling onto your prints
• Error 01.2:10
• Error 11:10
• Error 13.n:10
• Error 93:11

Options

• Trailing cable: none (saves $50.00), bare type or encased type. Match the type on your printer; the photo shows both.
• Ink tube PCA: none (saves $50.00), 4000 or 4000 PS

What's included

• Ink tube system
• Trailing cable and PCA, if you choose them
• Prepaid return shipping label for your old tube system (USA only)

How we rebuild it

OEM synthetic rubber seals shrink and crack with age. Every LPS rebuilt tube system gets:

• Every seal replaced with a durable silicone seal that does not shrink or crack over time
• New printhead ports (LPS design) with Dynaflex port seals that stretch up to 600% and resist chemicals and wear
• New check valves with all-stainless-steel internal parts

Installation

The replacement procedure is in section 8-33 of the HP Designjet 4000 service manual.

Core return terms

Returned tube systems must be complete, with no missing parts. Tube systems that have been disassembled or broken apart cannot be repaired without special tooling and new parts, so they have no core value and are not refunded.
