Mounted in the multi bypass tray. Drives the pick-up roller and
paper feed rollers that feed paper from the bypass tray into the
printer.
Mounted on the right rear corner of the printer (viewed from the
back). This fan pulls hot air from the interior of the printer and
pushes it out through a ventilation port.
Mounted on the left side of the printer, drives forward and reverse
to control the timing belt that moves the carriage left and right
during printing. The operation of the motor is controlled by the
horizontal encoder sensor (a long film strip) mounted behind the
carriage.
J007/J010: Runs forward to pump cyan (C) to Print Head 2, re-
verses to pump black (K) to Print Head 2.
J011: Runs forward to pump cyan ink, reverses to pump black ink
(K).
J007/J010: Runs forward to pump yellow (Y) to Print Head 1,
reverses to pump magenta (M) to Print Head 1.
J011: Runs forward to pump magenta (M) to Print Head 4, rever-
ses to pump magenta (M) to Print Head 1.
J007/J010: Not present.
J011: Runs forward to pump yellow (Y) to Print Head 4, reverses
to pump Yellow (Y) to Print Head 1.
Mounted in the maintenance unit. Drives the maintenance unit: 1)
Rotates forward to drive the shaft that raises and lowers the caps
during print head cleaning, 2) Reverses to drive the simple tube
pump that siphons ink from the print head through the right, 3)
Raises and lowers the wiper that removes ink collected around the
print head.
Mounted in the PFU. Drives the pick-up roller and paper feed roll-
ers that feed paper from the PFU tray into the printer.
Mounted behind the vertical encoder wheel and to the left of the
PSU. This motor, controlled by the rotation fo the vertical encoder
wheel and SENC board, drives the paper rollers that drive the
transport belt.
