HP Color LaserJet Enterprise CP4025 / CP4525. Service Manual
1. Theory of operation;
The product routes all high-level processes through the formatter, which stores font information, processes the print image, and communicates with the host computer.
2. Removal and replacement;
This chapter describes the removal and replacement of field-replaceable units (FRUs) only. Replacing FRUs is generally the reverse of removal. Occasionally, notes and tips are included to provide directions for difficult or critical replacement procedures. HP does not support repairing individual subassemblies or troubleshooting to the component level. Note the length, diameter, color, type, and location of each screw. Be sure to return each screw to its original location during reassembly. Incorrectly routed or loose wire harnesses can interfere with other internal components and can become damaged or broken. Frayed or pinched harness wires can be difficult to find. When replacing wire harnesses, always use the provided wire loops, lance points, or wire-harness guides and retainers.
