2005 Canon iR5570 / iR6570 Series Service Manual

• Model coverage: 2005 Canon iR5570 and iR6570 console-format multifunction systems.
• Maps the reader, printer, and main-controller architecture, including the configurations used with input, output, printing, and transmission accessories.
• Covers original exposure and image formation, from corona charging and dry one-component toner projection development through the IH fixing section.
• Details repair coverage for the process unit, drum cleaner unit, developing assembly, and fixing system, with component sequences and parts-replacement references.
• Includes service modes, image-adjustment standards, fixing nip checks, and oil-dish cleaning information used during diagnosis and post-service setup.
• Documents host-machine setup for the copy tray, card reader, and voice guidance kit, together with electrical construction and wiring-related reference material.

System Structure and Controller Coverage

The documentation follows the machine from the main controller through the reader and printer sections, showing how the electrical and mechanical systems work together. The controller architecture is based on the standard 512 MB memory and 20 GB HDD configuration used in these models. That information is relevant when tracing faults that cross between image processing, scanning, printing, storage, and machine control.

System configuration material identifies the supported input, output, printing, and transmission arrangements. It also covers the machine-side setup requirements for accessories such as the copy tray, card reader, and voice guidance kit. This gives a technician a clearer picture of the base-machine connections and settings involved before accessory installation or repair work begins.

Image Formation and Repair Coverage

The image formation sections describe the corona-based charging method, the dry one-component toner projection development process, and the IH heater fixing system. Rather than limiting coverage to routine cleaning, the manual addresses the construction and service relationships of the process unit, drum cleaner unit, developing assembly, and fixing components.

Parts-replacement material is organized around the affected assemblies and their operating sequences. This helps distinguish ordinary maintenance from repair work that requires access to the process, development, or fixing sections. Service-mode and image-adjustment information supports the checks required after components have been disturbed or replaced.

The specified operating range is 15 to 27.5 degrees Celsius with relative humidity from 25 to 75 percent. These limits provide useful context when evaluating charging, development, fixing, or image-quality behavior. The adjustment material also includes the applicable baseline information for fixing nip condition and oil-dish cleaning.

Diagnostics, Scope, and Safety

Electrical references, component sequences, service modes, and image-adjustment standards make this a machine-level repair publication rather than a basic operator guide. Its main scope is the reader, printer, and main-controller architecture, along with the base-machine installation and configuration points for the listed accessories.

High-voltage power supplies and the fixing heater area may remain electrically or thermally hazardous after operation. Internal inspection and repair should begin only after the machine has been shut down correctly, isolated from its power source, and allowed to cool as directed by the manual.
