Cautions after print head installation

Note: DO NOT loosen the red screws on both sides of the main chassis securing the carriage shaft position. *1: Media sensor correction This operation adjusts the correction value of the media sensor, installed in the sheet feeder unit, to the

EEPROM of the logic board ass’y. The adjustment is required when the sheet feeder unit or the logic board

ass’y is replaced, and values are automatically determined via use of calibration media kit (QY9-0064). *2: Calibration media kit The service tool for media sensor correction, consisting of 10 sheets of the reference plain paper, and 1

sheet of the reference white PET paper. *3: Red screws of paper feed motor The red screws securing the paper feed motor may be loosened only at replacement of the paper feed motor

unit. *4: For details, see Section 3.4 Adjustment / Settings. *5: Cautions after repair for trouble concerning printing or the print head re-installation After repair for trouble concerning printing or the print head re-installation, after emptying the ink in the

print head, (if users sent the printer with ink tanks, re-set it with ink tanks) and return the printer to users.

(See Section 3.3 Special Notes on Repair Servicing (2) Notes on after repair for trouble concerning printing

or re-installation of the print head.)

- After repair for trouble concerning printing

- After re-installation of the print head

(Before returning to

users)

- To prevent non-ejection of ink at initial printing (Empty ink from print head once.)

None. 6 min.

(2) Periodic maintenance

No periodic maintenance is necessary.

(3) Periodic replacement parts

There are no parts in this printer that require periodic replacement by a service engineer.

(4) Replacement consumables

There are no consumables that require replacement by a service engineer.

Error Solution Remarks

Press the Resume/Cancel button, and after confirming the following, perform print head alignment again:

- Set an appropriate type and

size of paper (plain paper, A4 or letter).

- Check that the print head

alignment pattern is properly printed (all ink ejected, no faint printing).

- Check that the paper ejection

slot is not exposed to light.

- W hen there are no problems

in the three items above, perform manual print head alignment.

Use the CD-R tray with an “A” mark.

When not performing CD-R printing, store the CD-R tray by hanging it on the projections on the back side of the printer.

*3: When setting the CD-R, align the marks on the CD-R tray to the marks on the paper output tray.
