1. GENERAL DESCRIPTION<br />
1.1 Special Features<br />
• High-speed, high-quality plotting<br />
MP303-UM-251-9370 1-1<br />
1. GENERAL DESCRIPTION<br />
A digital servo drive system and a 32-bit CPU combine to produce detailed plots with smooth curves at a<br />
maximum plotting speed of 700 mm/s (in all directions) and a mechanical resolution of 0.005 mm.<br />
• Various functions ensure clearly-defined plots<br />
A wide variety of functions come standard to ensure clearly-defined plots, including the Auto Pen Cap<br />
function which prevents pens at the pen station from drying up when not in use and a mechanical soft-landing<br />
mechanism that extends the pen's lifetime while providing a quieter working environment. The plotting speed<br />
and pen force most suitable for the pen type being used can be easily selected from the control panel.<br />
• Upright installation possible<br />
To conserve space, the plotter can be mounted on a pair of stands (provided as a standard accessory) for<br />
installation at a 60˚ angle.<br />
• Interface conditions are easily set<br />
The interface mode (RS-232C serial or Centronics parallel or USB-compatible) is automatically selected<br />
when the plotter is connected to a computer via the respective interface connector.<br />
If the plotter is set to Auto RS-232C mode, you just need to send plot data from the computer; the RS-232C<br />
settings are automatically selected so no bothersome settings are required.<br />
• Interactive operation<br />
Various functions can be set interactively by using the panel keys according to messages and prompts<br />
appearing on the display.<br />
• Vector sorting function<br />
This function speeds up plotting by minimizing the distance the pen travels in raised status from the end point<br />
of one line to the starting point of the next line.<br />
• Pen sorting function<br />
To speed up plotting by reducing the number of pen exchanges required, this function reorganizes the<br />
sequence in which plotting is performed so that each color is completely plotted before selecting the next<br />
pen.

6.7 Using the Test Modes<br />
6.7.1 Self Test<br />
MP303-UM-251-9370 6-8<br />
6. ELECTRICAL ADJUSTMENTS<br />
Your plotter comes with a self-test mode, which enables the plotter to check its own functions, without<br />
necessarily being connected to the computer.<br />
A correctly drawn test pattern signifies that all of the functions of the plotter (excluding the interface functions)<br />
have been tested and found normal. Be sure to run this self-test before connecting the plotter to the<br />
computer.<br />
Procedure<br />
(1) Check that the POWER switch is off and that pens are mounted in the pen station.<br />
(2) Turn on the POWER switch while holding down the LEFT ARROW POSITION key.<br />
The plotter is initialized.<br />
The prompts below are consecutively displayed.<br />
SelfTest<br />

(3) After initialization has been completed, place a sheet of paper on the writing panel.<br />
Press the CHART HOLD key to secure the sheet. The prompt below is displayed.<br />
Press<br />
Ent key<br />
(4) Press the ENTER key to draw the self-test pattern.<br />
The plotter repeatedly plots the same pattern until you cancel the self-test mode.<br />
To temporarily stop plotting, press the PAUSE key.<br />
To cancel the self-test mode, press the CANCEL key to stop plotting and then turn off the plotter.
6.7.2 Character Dump Mode<br />
MP303-UM-251-9370 6-9<br />
6. ELECTRICAL ADJUSTMENTS<br />
This mode allows experienced users to detect the cause of communication problems between the plotter<br />
and the computer. In Character Dump mode, the plotter produces an exact printout of the codes it receives,<br />
printing character data as ASCII codes and the non-character (control) data as two-digit hexadecimal values<br />
(e.g., 0A: Line Feed, 0D: Carriage Return).<br />
Procedure<br />
(1) Mount a pen in the pen station’s Pen 1 position.<br />
(2) Place a sheet of paper on the writing panel.<br />
(3) Hold down the DOWN ARROW POSITION key while you turn on the plotter.<br />
The plotter is initialized.<br />
CharDump<br />

(4) Secure the paper.<br />
The prompt below is displayed to prompt you to press the CHART HOLD key.<br />

(5) Once the paper is secured, the PROMPT lamp on the plotter blinks.<br />
The prompt below is displayed.<br />
Press<br />
ENT Key<br />
(6) Press the ENTER key to enter the Character Dump Mode.<br />
The plotter prints “** DUMP MODE (V*.** GL) **” on the paper and then awaits data from the computer.<br />
The message below briefly reappears on the display.<br />
CharDump<br />
Mode<br />
(7) When the computer runs an application program and outputs the data to the plotter, it starts printing the<br />
received data in ASCII format.<br />
(8) To exit the Character Dump Mode, turn off the plotter and then turn it back on using only the POWER<br />
switch.
6.7.3 Debug Mode<br />
MP303-UM-251-9370 6-10<br />
6. ELECTRICAL ADJUSTMENTS<br />
This mode is used to locate programming errors in your application program.<br />
When the plotter is in Debug Mode, its buffer size is reduced to permit easier detection of the section of the<br />
program that is causing the plotting error.<br />
Procedure<br />
(1) Mount a pen in the pen station’s Pen 1 position.<br />
(2) Place a sheet of paper on the writing panel.<br />
(3) Hold down the ENTER key while you turn on the plotter.<br />
The plotter is initialized.<br />
Debug<br />

(4) Secure the paper.<br />
The prompt below is displayed for a few seconds to prompt you to press the CHART HOLD key.<br />
Set<br />
Paper!<br />
The prompt below is displayed<br />
Ready<br />
(5) The plotter is now in the Debug Mode.<br />
(6) Run the target program at the computer for output to the plotter.<br />
The message DEBUG MODE is displayed for a few seconds.<br />
In this mode, the plotter’s buffer memory is reduced to the following sizes:<br />
• In RS-232C mode : 256 bytes<br />
• In Centronics mode : 10 bytes<br />
(7) To exit the Debug Mode, turn off the plotter and then turn it back on using only the POWER switch.<br />
HINT: When using the RS-232C interface, the timing of data transmission varies with the selected<br />
handshake mode as follows.<br />
• During hardwire handshaking:<br />
The ER (DTR) signal line goes off when the available space in the buffer drops to 64 bytes.<br />
It goes on when the available space in the buffer rises to 128 bytes of data.<br />
• During Xon/Xoff handshaking:<br />
Xoff status is entered when the available space in the buffer drops to 32 bytes.<br />
Xon status is entered when the available space in the buffer rises to 128 bytes of data.<br />
NOTE: After the plotter is turned off, Debug mode is not resumed when only the ENTER key is<br />
pressed.<br />
The Debug mode cannot be used with the USB interface.

8.1 Hardware Error<br />
Displayed message Cause<br />
POSITION<br />
This message appears when, for some reason, the current pen position<br />
XY ALARM<br />
is invalid. In this case, turn the plotter off and then back on again.<br />
8.2 GP-GL Command Errors<br />
In GP-GL command mode, the plotter displays the error messages below if an error occurs for which<br />
masking of the corresponding Error bit in the STATUS byte has been disabled using the ˝ command.<br />
Displayed message Cause<br />
A command error occurs if a hexadecimal code from 60H to 7EH is<br />
E1.<br />
processed as a command character. This message may also appear if<br />
COMM ERR the RS-232C interface conditions are improperly set or if the program<br />
being run at the computer was not written using GP-GL commands.<br />
When a command specifying coordinate values is being processed, a<br />
E4.<br />
parameter overflow error occurs if a numeric parameter exceeds the<br />
PARA OV<br />
“Parameter Range”.<br />
An input/output error occurs during the transfer of data via the interface.<br />
E5.<br />
With the RS-232C interface, this message indicates that the parity or<br />
I/O ERR data length may be improperly set. Check your interface conditions once<br />
more.<br />
Cancelling an error status<br />
You can cancel an error status using any of the methods below, thereby setting the status of the<br />
corresponding Error bit to zero.<br />
(1) Execute a READ STATUS WORD 1 or READ STATUS WORD 3 command.<br />
(2) Press the ENTER key. (Effective only in case of a data format error.)<br />
Note: If a data format error has occurred, performing either Method (1) or (2) above while<br />
execution of the next command is temporarily suspended enables that command to be<br />
executed.<br />
(3) Initialize the plotter.<br />
(4) Execute the INTERFACE CLEAR command.<br />
Note: Method (3) or (4) clears all the data in the plotter’s buffer memory.
