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
