4.1

Overview

This section describes procedures for disassembling the main components of the Stylus

Photo R260/R265/R270 and R360/R380/R390

Unless otherwise specified, disassembled units or components can be reassembled by

reversing the disassembly procedure.

Procedures which, if not strictly observed, could result in personal injury are described

under the heading “WARNING”.

“CAUTION” signals a precaution which, if ignored, could result in damage to

equipment.

Important tips for procedures are described under the heading “CHECK POINT”.

If the assembly procedure is different from the reversed disassembly procedure, the

correct procedure is described under the heading “REASSEMBLY”.

Any adjustments required after reassembly of components or parts are described under

the heading “ADJUSTMENT REQUIRED”.

When you have to remove any components or parts that are not described in this

chapter, refer to the exploded diagrams in the appendix.

The precautions in the two lists below (WARNING and CAUTION), must always be

followed during disassembly and assembly.

Disconnect the power cable before disassembling or assembling

the printer.

If you need to work on the printer with power applied, strictly

follow the instructions in this manual.

Wear protective goggles to protect your eyes from ink. If ink

gets in your eye, flush the eye with fresh water and see a doctor

immediately.

Always wear gloves for disassembly and reassembly to avoid

injury from sharp metal edges.

Use static discharge equipment such as anti-static wrist straps

when accessing internal components to protect sensitive

electronic components and circuitry.

Never touch the ink or wasted ink with bare hands. If ink comes

into contact with your skin, wash it off with soap and water

immediately. If irritation occurs, contact a physician.

Make sure the tip of the waste ink tube is located at correct

position when reassembling the waste ink tube, or it will cause

ink leakage.

Use only recommended tools for disassembly, assembly or

adjustment of the printer. (

Table 4-1, “List of Tools,” on

page 58

)

Be sure to tighten the screws to the specified torque.

Apply lubricants and adhesives as specified. (See Chapter 6

Lubrication (p.131)

for details.)

Make the specified adjustments when you disassemble the

printer. (Chapter 5 contains additional information on

adjustments.

When using compressed air products, such as air duster, for

cleaning during repair and maintenance, the use of such

products containing flammable gas is prohibited.

Be careful not to scratch or damage the coating on exterior

surface of the product during disassembly and reassembly.
