DISC REMOVAL PROCEDURE (FORCED EJECTION)

• Remove the upper case.
• Insert a clip in the hole of a drive and open a tray.

OPTICAL DEVICE REPLACEMENT

• Install it in PC after downloading two set of software.
• Microsoft .NET Framework Version 2.0 Redistributable Package (x86)
• Microsoft .NET Framework 2.0 Service Pack 1 (x86)
• Take a photograph of the bar code on the optical device. The valid bar code photo as shown.

• Drag-and-drop the bar code photograph to the icon of decode software (BDPRdec).

The decode software is a complete set of “BDPRdec”,  “T asman.Bars.dll”, and “SavePath”.

Because decode software cannot be attached, it separately distributes it.

• Input the password when you start decodes software.

Inquire of each service headquarters because the password cannot be disclosed.

• Write the decode data to the set.

Replace both BU and MB

Requirement

• Digital camera (recommend with macro mode)
• Barcode decoder (BDPRdec_ver2.0) installed in JIG PC’s
• USB memory
• ESD work bench.

The servo adjustment procedure will be carried out during OP data Writing.  There is no manual adjustment procedure. LD ON TIME history doesn't carry over.

Do not touch any optical block parts, Turn Table and during replacing. BD Laser diode is very sensitive.

EPSON STYLUS PHOTO - R280 - R285 - R290 - HOW TO ADJUST PG

PG ADJUST

Adjust the distance between the head surface and the Paper Guide Front Assy (platen) properly and adjust the parallelism on the 0th column side and on the 80th columns side to ensure reliable print quality.  Once the Carriage Assy and/or Adjustment Bushes have been removed or whenever necessary for any other reason, make this adjustment to correct the deviation of the platen gap.

Tools to be used

• Thickness gauge:  1.15 mm (x2) 1.3 mm (x2)
• Phillips screwdriver.

1. The thickness gauge to be used must be free from dust and dirt and from deformation. Be sure to clean it before use.  ! Take care that the Print Head is not soiled or scratched.  To ensure high accuracy of adjustment, install new ink cartridges in the carriage, and move the carriage right and left by pulling the belt without holding the carriage.
2. Make this adjustment after installing the mechanism unit in the Housing Lower. (Install the Linear Scale after adjustment.)
3. With EPSON Stylus Photo R280/R285/R290, four stages of PG setting are available by means of the APG Mechanism. However, make this adjustment with the mechanism in the minimum PG position (PG-: 1.2 mm).

Adjustment procedure (Specified PG value: 1.2 ± 0.1 mm)

• Install new ink cartridges in the carriage.
• Remove the Cable Holder Frame.
• Check that the APG Assy and the carriage are in the PG-position.
• Move the carriage to the centre of the platen, and place 1.15 mm thickness gauge on the left aligning its left edge with the second rib of the Front Paper Guide. And place another 1.15 mm thickness gauge on the right aligning its right edge with the rightmost rib of the Front Paper Guide.

NOTE: The thickness gauge must not be set over the leftmost rib on the Front Paper Guide.

• Pull the Timing Belt to move the carriage to the left end.
• If the carriage comes in contact with the gauge, adjust the Left Parallelism Bush to raise the carriage to a position where the Print head does not come in contact with gauge.
• Pull the Timing Belt to move the carriage to the right end.
• If the carriage comes in contact with the gauge, adjust the Right Parallelism Bush to raise the carriage to a position where the Print head does not come in contact with gauge.
• Move the carriage to the middle area of the platen, and place 1.3 mm thickness gauges at the left and right ends of the platen.
• Pull the Timing Belt to move the carriage to the left end.
• If the carriage does not come in contact with the gauge, make the adjustment again.
• Pull the Timing Belt to move the carriage to the right end.
• If the carriage does not come in contact with the gauge, make the adjustment again.
• Mark the indicated graduation position of the right and left Parallelism Bush, and tighten the screws.(Screw tightening torque: 0.8±0.1 N•m)
