b. Installing the carriage belt
Install the carriage belt[2] with its complete set of teeth engaged with carriage belt stopper[1].
c. Action following the replacement of the carriage unit/multi sensor
Because the distance between the multisensor (in the carriage unit) and the nozzles (in the printhead) is varied
from one unit to another, the printer as shipped has its optical axis corrected to adjust the image write position.
When the carriage unit or multisensor has been replaced or disassembled and reassembled, they require
adjustment.
Execute service mode under the following conditions:
Service mode: SERVICE MODE > ADJUST > PRINT PATTERN > OPTICAL AXIS
Head height: LOW position
Media type: Gloss photo paper
Paper size: 36 inches
d. Removing the head holder
(1) Drain the printer of inks. See Disassembly/Reassembly > Tips on Disassembly/Reassembly > Ink Drain.
(2) Switch off the printer and move the carriage to above the platen. See Disassembly/Reassembly > Tips on
Disassembly/Reassembly > Open Cap/Shift Wiper Unit.
(3) Remove the shaft cleaner, tube holder cover and tube holder.
(4) Remove the printhead.
(5) Disconnect all connectors from the carriage relay PCB.
(6) Release the two flexible cables from the carriage claws (to prevent the elevation and defective contact of the
flexible cable on the head holder side).
