components of the Stylus Photo R220/R230. Unless otherwise specified, disassembled 
units or components can be reassembled  by reversing the disassembly procedure.
Procedures which, if not stri ctly 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 desc ribed under the heading “CHECK POINT”.
If the assembly procedure is different fr om 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 parts or components that are not described in this 
chapter, refer to the exploded diagram in the Appendix.
Read the next section “Precautions”  fully before starting disassembly.2.1.1  PrecautionsBefore starting the disassembly or reassemb ly of the product, read the following 
precautions given under the headings WARNING and CAUTION.
2.1.2  Recommended ToolsUse only specified tools to avoid damaging the printer.

  
„
Disconnect the power cable befo re disassembling or assembling 
the printer.
„
If you need to work on the prin ter 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 disass embly and reassembly to avoid 
injury from sharp metal edges.
„
To protect sensitive microproces sors and circuitry, use static 
discharge equipment,  such as anti-static wrist straps, when 
accessing intern al components.
„
Never touch the ink or wasted in k with bare hands. If ink comes 
into contact with your skin, wa sh it off with soap and water 
immediately. If you have a skin  irritation, consult a physician.
„
When reassembling the waste ink  pads and tray, always make 
sure that the waste ink tube is  fitted correctly in the specified 
place. Fitting the ink tube in oth er than the specified position can 
cause ink leakage.
 \b	
 
„
When transporting the printer af ter installing the ink cartridge, 
pack the printer for transporta tion without removing the ink 
cartridge and be sure to secure th e Ink Cartridge to the printer 
cover with tape tightly to keep it from moving.
„
 Use only recommended tools for  disassembling, assembling or 
adjusting the print er. (Refer to Table  2-1 Tool List.)
„
Observe the specified torque  when tightening screws.
„
Use the specified lubricants and  adhesives. (Refer to Chapter 4 
for details.)
„
Make the specified adjustment s when you disassemble the 
printer. (Refer to Chapter 3 for details.)
„
When using compressed air products; such as air duster, for 
cleaning during rep air and maintenance, the use of such 
products containing flam mable gas is prohibited.

							EPSON Stylus Photo R220/R230Revision ADISASSEMBLY / ASSEMBLY Caution regarding assembling/disassembling the printer mechanism, and how to ensure the quality of reassembled product 432.2  Caution regarding assembling/disassembling 
the printer mechanism, and how to ensure the 
quality of reassembled product
For the existing Low End models, it is basically forbidden to remove the Lower 
Housing from the Printer Mechanism. This  is because the strength of the Main Frame 
is    not strong enough, therefore, the Main Frame may be deformed when removing/
reinstalling it from/to the Lower Housing.
For that reason, when replacing the Ink Syst em or the PF Motor, it is recommended to 
replace not only the Lower Housing  but also the Printer Mechanism.
For this printer, it is neces sary that the Lower Housing  be removed from the Printer 
Mechanism when replacing the Waste  ink Pads or the Ink System Unit. 
Therefore, this chapter specifies the disa ssembly/assembly of the Printer Mechanism 
which the Lower Housing has been taken out in order to secure the quality of the 
repaired items.†
Cautions for disasse mbly/assembly of the Printer Mechanism
1. the Printer Mechanism with the Lower Housing • Do not hold the Guide Plate, CR  ⇒ Deforming of the Main Frame and 
the Guide Plate, CR may give some bad influence to PG or printing.
• Do not touch the CR Guide Shaft an d the surface of the head nozzle.
• Note that the screws that secure the  Main Board is M4, not M6. If you use 
M6 screw mistakenly, it will interfere with the Carriage.
• Be careful not to let the damper of  the CDR come off as it is secured by 
the Lower Housing.
2. the Printer Mechanism without the Lower Housing
• Make sure the exact att aching position in all X, Y and Z directions. See 
the Ensuring the attaching posit ion in X, Y and Z directions.
• Be sure to remove the Frame Support before removing the PF Roller  Unit, Roller EJ, and the Front Paper Guide.
• Be sure to confirm that The Waste  Ink Tube is correctly installed.
• Be sure to route the cables of th e Guide and Tray Sensor correctly.
• The APG gear must be engaged properly.
„
Ensuring the attaching position in X, Y and Z directions.
Installing each part or component of th e Printer Mechanism accurately can be 
made by determining the positions of them in relation to the Lower Housing.
[When Servicing]
Check that there is no gap between  the Main Frame and the Lower Housing.
[Reference]
In order to ensure the accu racy of installation positions, it is necessary to 
make sure the positions in X, Y and Z directions.
[X-axis direction]
• Check if the Main Frame is correct ly set to the groove of the Lower 
Housing.
• Check if there is no gap between th e Main Frame and the Lower Housing.
[Y-axis direction] • Check if the slot of the Main Frame  is correctly attached to the projection 
of the Lower Housing.
[Z-axis direction] • Check if there is no gap between th e Main Frame and the Lower Housing.
• Check if correctly secured with the ta bs (2 on the left, 1 on the right, 
1 on the right front) of the Printer Mechanism.
„
Maintaining the perpendicularity of the Guide Rail (The Guide Rail is secured  by the Ink Cartridge Holder and the Print Head).
Deformation of the Guide Plate, CR ma y cause the defective print/operation.
[When Servicing]
Specify the correct raising position for th e Main Frame so that it will not be 
deformed.
„
Installing the ASF Unit, the Main  Board and the Paper Guide, Upper
Forces exerted on the Main Frame when  installing the three components may 
deform the frame resulting in a malfunc tion of the printer or print quality 
problem.
[When Servicing]
Hold the opposite side of  the components securely , when installing them.

„
Maintaining the levelness of the CDR Guide Assy.
Deformation of the CDR Guide Assy. may cause the defective print.
[When Servicing]
Disassemble/assemble carefully the CDR Guide Assy.
†
Ensuring the quality of reassembled products
It can be judged that the quality of the reassembled products is ensured if the 
printing test with the Adjustment program is successful.
