[Refer to 3-2Instruction for Servicing (1) Wiring arrangement of flexible cable and harness, and connection of connectors]Be careful not to drop down ferrite core to be broken.Be careful not to let electrostatic break electric parts down.Disconnect the power cord, leave the unit about 1 minute (to discharge the stored charge of the capacitor) and dismount thepart (to prevent MAIN PCB ASS'Y broken).Do not stain inappropriate part with TIMING grease. Do not scratch or damage parts and the unit.Be careful not to damage or stain external cover.

3-2 Instruction for Servicing3-2-1 Detaching the front cover1) Lift the bottom side of the front cover as shown in the picture and detach the cover pulling the upper sideoutwards.2) Detach the front face and front cover lifting up the bottom side of the front face.

3-2-2 Attaching the front cover1) Attach the front face.2) Attach the front cover putting hooks on both sides of the front cover to the main unit.

3-2-3 Handling the carriage unit1) If CCD is shocked, the optical axis will be out of alignment and scanned images will not be outputted properly.Be careful when handling a carriage unit.2) Be careful not to put dirt or dust on the light guide.

3-2-4 Detaching the FFC cableNotice:Be careful not to crease the FFC cable.This operation is performed in the area around CCD. If CCD is shocked, the optical axis will be out of alignmentand scanned images will not be outputted properly. Be careful when handling a carriage unit.1) Move the carriage to the center of the main unit. Pull the FFC cable to the near side and take it from the hook.

2) Lift the hook on the connecter.3) Pull the ferrite cores to the near side while pushing them down and detach the ferrite cores and the FFC cable.

3-2-5 Detaching the FFC cable (Main PCB)1) Lift the hook on the connecter and then detach the FFC cable. 3. Servicing

CanoScan 8800FMaintenence4. Transport4-1 TransportWhen a unit, such as after repairing, is being transported, it needs a few cares in preparation fortransport.1) Turn on the power switch of scanner and return Carriage unit to home position.2) Move the lock switch to ON side to fix Carriage unit.3) Fix the scanner body with tape. [See the figure below]Note:Use a fixing tape almost equivalent to the polyester one used for shipping product. (A tough, not easilypeelable tape which would not leave its glue after peeled. ) 4.

R2·ConfidentialPart 2Technical Reference

CanoScan 8800FTechnical Reference1. New Features(1) CCD scanner with white LED, no need to warm upHigh brightness white LED is used as light source for reflective documents and films.To scan high quality images, technology to convert point light source of LED to line light source with uniformintensity is essential. It is realized by applying our unique technology for optical guiding device developmentacquired by CIS unit development of LiDE series.Warming up required for traditional fluorescent lamp (approximately 30 seconds at normal temperatures) is nolonger needed. The first scanning starts immediately.Turning on lamp after scanning is not required. It also serves the energy-conservation.(2) Faster scanning speed at low resolutionThe scanning speed at 300/600dpi, which is often used to scan reflective documents, becomes faster by improvingthe data reading method from CCD.Color 300dpi : 1.0msec/line (8600F: 3.6msec/line)Color 600dpi : 1.7msec/line (8600F: 3.6msec/line)(3) Reduced body sizeNewly designed carriage (ST lens is used) and white LED used as light source of FAU allow to make the bodyapproximately 17% thinner than that of 8600F. 1.
