
The operation panel (1) and scanner unit (2) are mounted on the scanner stand
(3).

The main unit is mounted on the main unit stand (4). The main unit and scanner
stand can be easily separated. Separation is required for most service procedures.
Also, the scanner unit can be easily removed and placed on a table or desk for
easy access so that the machine can be operated from a sitting position.

The carriage unit (5) houses the print head units, the DRESS sensor, horizontal
encoder sensor, lift sensors (used for print head gap adjustment) and the OCFS
system that monitors ink level in the print head unit sub tanks during printing.

The air release solenoid (6) purges air from the ink supply system.

The maintenance unit (7) cleans the print heads mounted on the bottom of the
carriage unit. It contains two motors and three sensors that control the print head
cleaning cycle. (This is described in a later section.)

The ink supply unit (8) houses the ink cartridges and ink pumps that supply ink to
each print head unit when ink runs low in a print head unit sub tank.

Roll Unit 1 (Standard) (9). Holds one roll of paper. The stoppers can be adjusted
easily to accept different widths of roll paper.

Roll Unit 2 (Option) (10). Holds one roll of paper. Its stoppers can also be adjusted
easily to accept different widths of roll paper.

The exit stacker (11) (Standard) is mounted on the front of the machine and
requires installation. The exit stacker can be folded in when it is not being used (or
for stacking outputs in a well-like structure) or extended for output of long sheets.
