Common user issues on HP DesignJet 800 Series – and what helps The HP 800 is durable, but like any large-format printer it can develop typical consumable-related symptoms. Here’s what customers most often report—and what usually solves it: - Streaks or banding – often caused by a worn or clogged printhead; replacing the HP 11 printhead in the affected color can restore smooth fills.
- Missing lines in CAD drawings – check the relevant color channel; a fresh cartridge helps, but recurring gaps usually point to the printhead.
- Colors look dull or inconsistent – replacing the specific CMY cartridge (or set) often stabilizes results, especially in high-coverage prints.
- Frequent cleaning cycles – can increase ink consumption; selecting reliable cartridges and replacing aging printheads reduces the need for repeated maintenance routines.
