Description
Motors
MT
Bypass Paper Feed
Motor – STM4
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.
MT Cooling Fan
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.
MT
Horizontal Motor -
DCM1
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.
MT
Ink Pump Motor (KC)
– DCM3
Runs forward to pump cyan (C) to Print Head 2,
reverses to pump black (K) to Print Head 2.
MT
Ink Pump Motor (M) –
DCM4
Runs forward to pump yellow (Y) to Print Head 1,
reverses to pump magenta (M) to Print Head 1.
MT
Maintenance Motor –
MT STM1
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.
MT
PFU Paper Feed
Motor – STM2
Mounted in the PFU. Drives the pick-up roller and paper
feed rollers that feed paper from the PFU tray into the
printer.
MT
Vertical Motor
(DCM2)
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.
