Special Features
The MP303-04 is an A3-format flatbed plotter that provides high performance for diverse applications at low
cost.
The MP303-04 comes with a digital-servo drive system and a 32-bit CPU, achieving a maximum plotting speed
of 700 mm/second at a mechanical resolution of 0.005 mm.
■ High-speed, high-quality plotting
A digital servo drive system and a 32-bit CPU combine to produce detailed plots with smooth curves at a
maximum plotting speed of 700 mm/s (in all directions) and a mechanical resolution of 0.005 mm.
■ Various functions ensure clearly-defined plots
A wide variety of functions come standard to ensure clearly-defined plots, including the Auto Pen Cap function
which prevents pens at the pen station from drying up when not in use and a mechanical soft-landing mechanism that extends the pen's lifetime while providing a quieter working environment. The plotting speed and pen
force most suitable for the pen type being used can be easily selected from the control panel.
■ Interface conditions are easily set
The interface mode (USB, RS-232C serial or Centronics-compatible parallel) is automatically selected when
the plotter is connected to a computer via the respective interface connector.
Even if multiple data are sent via both the Centronics and the RS-232C interfaces, the data that arrived later is
discarded and overwriting of data will not occur. In addition, as the plotter comes equipped with three preset
modes for the RS-232C interface conditions setting, most major CAD software can be used by just selecting
one of these modes.
When the MP303-04 is set to Auto RS-232C mode, you just need to send plot data from the computer; the RS232C settings are automatically selected so no bothersome settings are required.
■ Upright installation possible
To conserve space, the plotter can be mounted on a pair of stands (provided as a standard accessory) for
installation at a 60° angle.
■ Interactive operation
Various functions can be set interactively by using the panel keys according to messages and prompts appearing on the display.
■ Vector sorting function
This function speeds up plotting by minimizing the distance the pen travels in raised status from the end point of
one line to the starting point of the next line.
■ Pen sorting function
To speed up plotting by reducing the number of pen exchanges required, this function reorganizes the sequence in which plotting is performed so that each color is completely plotted before selecting the next pen.

■ For Horizontal Use
Be sure to install the plotter on a stable, flat surface for use.
Installation space: 67 mm x 45 mm
■ Using the Tilt Stands
Mount the plotter on the tilt stands provided with this plotter by following the steps below.
(1) Insert the two hooks in each stand into the holes in the plotter's base, and then gently pull each stand

1.3 Mounting the Pens
■ Mounting a Pen in the Pen Station
Fit the pen's lower groove into the notched section of the pen station. Be sure to mount the pen so that its pen
cap is pressed down and its pen tip is completely inside the pen cap.
The figures below show examples of a correctly mounted pen.
A correctly mounted pen
When mounting a pen, there should be no gap between the pen station's notched section and the pen (shown
below on the left) and the pen should not be outside of its pen cap (shown below on the right). An incorrectly
mounted pen may cause unsatisfactory plotted results or plotter malfunctions.
Incorrectly mounted pen
NOTE
Whenever possible, try to consistently use the same Pen No. for a specific color. If you mount another pen
of a different color, the ink of the previous pen will adhere to the tip of the newly mounted pen and may
cause the pen to initially plot lines of mixed colors.
1-5
■ Removing a Pen
Facing the plotter so that the pen station is on your left, remove the pen by gently pulling it out to the right and
toward you along the notched section of the pen station.
■ Using the rubber inserts for the pen caps
Your plotter is provided with eight rubber inserts for the pen caps. Each rubber insert is placed inside the pen
caps in the pen station to prevent the ink in the mounted pen from drying up. Be sure to use these rubber inserts
only when using high-speed ceramic pens, refillable ink pens, or disposable ink pens. Never use the inserts with
water-based fiber-tip pens.
When a rubber insert is placed inside a pen cap, the tip of the mounted pen will lightly touch the rubber insert,
thus better maintaining the pens' conditions than when rubber inserts are not used.
Especially when using refillable ink pens, disposable ink pens or high-speed ceramic pens, be sure to use
rubber inserts, otherwise the pen tips may dry up or drip in the caps.
Mounting the rubber inserts
Use the tweezers provided to hold the rubber insert as shown below, then place it inside a pen cap at the pen
station.
When the rubber insert is mounted, the pen tip will contact the rubber insert as shown below.
NOTE
• Whenever possible, try to consistently assign the same color pens to each Pen No. If you mount another
pen of a different color, the ink of the previous pen (which will still be on the rubber insert) will adhere to
the tip of the newly mounted pen and may cause plotting to initially be performed using a mixed color.
Also be sure to periodically wash the rubber inserts for the pen caps with water to clean off any residual
ink.
• If you will not use the plotter for a long time, be sure to remove the pens from the pen station and cap
them.
1-6
1.4 Turning the Power On
CAUTION
(1) Check that the power switch is off (the “O” side should be down). If a pen is attached to the pen carriage,
remove the pen and return it to its position at the pen station.
(2) Plug the AC adapter into the plotter's AC inlet, then plug the other end of the cord into an electrical outlet
of the rated supply voltage.
(3) Turn on the plotter by pressing the "I" side of the power switch. The control panel's POWER lamp lights.
When the plotter is turned on, if the POWER lamp blinks, the plotter makes an abnormal noise, or it does
not function at all, immediately turn off the plotter and follow the instructions in section 5.3, “The Power is
Turned On But the Plotter Doesn't Operate.”
