4 BASIC OPERATION

4-1 Making the Connection with the Computer

*Always make sure that the power is off on both the computer and the PNC-900 whenever any cables are connected or disconnected.

Power outlet

Power cord

Cables are available separately. One which you are sure matches the model of computer being used should be selected.

When the PNC-900 is connected to the computer via the serial port, the communication parameters for the PNC-900 need to be set at the same values as for the computer. Use the DIP switches on the right-hand side of the PNC-900 to make these settings. Refer to "4-2 DIP Switch Settings" on page 5 to make the correct settings.

4-2 DIP Switch Settings

* DIP switches settings must be made only when the power is turned off.

The DIP switches are located on the right-hand side of the unit. The settings that can be made with these DIP switches are the communication parameters for when the serial port is used, and the value for the blade offset.

When the PNC-900 and the computer are connected through the serial port, use SW-1 through SW-6 to make the correct settings for communication parameters.

The blade offset, which is set with SW-7, should normally be set to OFF (0.25 mm).

The setting for sheet weight, made with SW-8, should normally be set to OFF (light). See "Cutting a Thick Sheet" on page 11 for an explanation of the settings for SW-8.

???All DIP switches are set to OFF when shipped from the factory.

???When SW-2 is set to OFF, SW-3 may be set to either ON or OFF.

4-3 Installing the Blade

*Always make sure the power switch is off before installing (or replacing) the blade. To prevent injuries, be very careful when handling the blades.

Do not touch the tip of the blade with your fingers, as the cutting performance of the blade will be impaired.

???Installation

(1)Insert the blade into the blade holder until it snaps into place with an audible click.

*Take care not to break or chip the blade.

4-4 Loading the Sheet ??? SETUP Key

???Turning on the Power

*When the power switch is pressed to turn on the unit, the tool carriage moves. Take care to ensure that your hands or other objects do not become caught in the moving parts. When turning the power to the unit off and then on again, wait at least 10 seconds after switching the power off before switching it back on.

Switch on the power switch on the left side of the PNC-900.

??? Loading the Sheet

Sheets with a width (horizontal dimension) of 50 mm (1-15/16") to 305 mm (12") can be loaded. There is no particular restriction on sheet length (vertical dimension). This means that either cut sheets or roll sheets can be used.

CAUTION

The tool carriage moves when the SETUP key is pressed. Take care to ensure that your hands or other objects do not become caught in the moving parts. Be sure to raise the sheet loading lever before attempting to move it. Never attempt to force the sheet loading lever.

(1)Move the sheet loading lever Before attempting to move the pinch roller, be sure to lower the sheet loading lever.

When you have finished loading the sheet, be sure to set the origin to the bottom left of the sheet. See "4-5 Setting the Origin Point" on page 8 for an explanation of how to do this.

* When using a roll sheet, load in place by passing the front edge of the sheet through from the rear of the PNC-900 over the platen.

It may be helpful to use a sheet base (available separately).

??? Removing the Sheet

About 1 mm (about 0.04")

24,998 mm (984-1/8")

The PNC-900 allows you to set the origin point (0,0) to any location in the cutting area.

When the origin has been set at the desired point, cutting can be carried out anywhere on the loaded sheet.

After the sheet has been loaded, be sure to set the origin to the bottom left of the sheet. (When the Rotate function is used by pressing the ROTATE key, the direction of cutting is rotated 90??, moving the origin to the bottom right of the sheet.)

Also, to make efficient use of a sheet, you can set a new origin in an area on the sheet that has not been cut and then carry out cutting.

Immediately after loading a sheet and pressing the SETUP key to illuminate the SETUP LED, the origin point (0,0) is automatically set to a location near the stationary pinch roller.

When loading the sheet, the origin is set at the left front edge of the sheet if the sheet is loaded close to the stationary pinch roller without pulling the part of the sheet closest to the front of the unit over the platen. This makes it unnecessary to set a new origin point.

When the sheet is loaded with the part of the sheet closest to the front of the unit aligned with the guide line on the platen, no cutting is carried out on the portion of the sheet that is closer to the front of the unit than the origin point (i.e., cutting cannot be performed on areas of the sheet with negative coordinates). Follow the procedure described below to set the origin to the lower left edge of the sheet.

Procedure

* If a sheet has not yet been loaded, then before setting the origin point, refer to "Loading the Sheet" on page 7 to load the sheet correctly. Loading a sheet after the origin has been set (by pressing the SETUP key to extinguish the SETUP LED) cancels the origin that has been set.

Use the , , , and keys to move the tool carriage to the position on the sheet where the origin point is to be set.

Before carrying out actual cutting, you may wish to perform a "cutting test" to check whether the unit produces the cutout satisfactorily.

This "cutting test" allows you to determine whether the settings you have for the blade force are appropriate. See below for a detailed explanation of blade force.

Procedure

*If a sheet has not yet been loaded, then refer to "Loading the Sheet" on page 7 to load the sheet correctly.

Move the pen force control slider all the way to the left (minimum blade force). Increase blade force gradually, keeping an eye on how well the sheet is being cut.

Press the TEST key

??? Cutting test starts

TEST

Use the , , , and keys to move the tool carriage to the position on the sheet where the cutting test is to be executed.

The resulting cutouts will then appear as illustrated. When completed, first peel off the portion indicated by slanted lines. If it can be peeled off by itself, without disturbing the square, you will know that the blade force is at the appropriate level. Next, peel off the square, and look at the backing that was under it. If you can clearly make out the lines left by the blade, you will know that you have the optimum setting.

Peel off first

Then peel this off

Origin

If you do not get results like those shown above, adjust the pen force control slider to obtain the appropriate blade force.

How to Adjust Blade Force

The pen force control slider is located on the right side of the unit. Move the blade force control slider sideways to alter the blade force.

When slid to the farthest setting on the left, the blade force will be set to 30 g. As the slider is moved to the right, the blade force will be gradually increased. When at the farthest setting on the right, the blade force will be set to 200 g, which is the maximum blade force setting provided by the unit. At the center, the blade force will be approximately 120 g.

When making the blade force setting, it is important to take into consideration the hardness of the blade and the thickness of the sheet to be cut, and set the most appropriate value. If the blade force is too weak, the sheet will not be cut satisfactorily. If the blade force is too strong, blade life will be shortened.

Additionally, be aware that problems such as the following may occur.

???The sheet is easily torn

???The blade pierces the sheet

???Cutting extends through the base paper, and normal advancing of the sheet becomes impossible

???The unit suffers damage

4-7 Downloading Cutting Data

The unit will begin cutting when it receives cutting data sent from the computer.

??? Software Settings

When cutting with commercially available application software, select PNC-900 as the setting for the output device. (If the PNC-900 cannot be selected, choose any model in the CAMM-1 series -- PNC-1900/1600, PNC-1800, PNC-1100, PNC-1000A, or PNC-1000.)

Select either the parallel (Centronics) or serial (RS-232C) interface. Choose the one that the host computer and the PNC-900 are connected by.

*When loading a sheet that has been cut, be sure to use a sheet that is about 50 mm longer than the vertical size of the cutting data. If data larger than the vertical length of the sheet is sent, the PNC-900 will attempt to cut the data even if it does not all fit in the sheet. This means that the sheet is dislodged from the grit roller, and cutting continues with no sheet. This can cause not only breakage to the blade but also damage to the unit, and adequate care is required to prevent this.

If the sheet becomes dislodged, immediately press the PAUSE key or turn off the power switch.

???Pausing Cutting Operations ??? PAUSE Key, PAUSE LED, and SETUP Key

If you want to stop the PNC-900 momentarily while it is performing cutting, follow the procedure described below.

??? Continuing Cutting

Cutting After Changing the Sheet

Again carry out the procedure described from "Loading the Sheet" on page 7 to "4-7 Downloading Cutting Data" on page 10. * If a sheet of the same type is used, there is no need to perform a cutting test.

Continuing Cutting on the Same Sheet

Refer to "4-5 Setting the Origin Point" on page 8 to set the origin for the area where cutting is to be carried out next. Then send cutting data from the computer to the PNC-900.

??? Cutting a Thick Sheet

SW-8, one of the DIP switches located on the right side of the unit, is normally set to OFF (light).

It is recommended that SW-8 be set to ON (heavy) when cutting a thick or heavy sheet. Cutting speed slows down when this is done, but the force used to move the sheet and the blade increases.

* Remember that DIP switch settings must be made only when the power is turned off.

4-8 Applying the Completed Cutout

Once cutting has been completed, the resulting work can be affixed in place as explained below.

Procedure

Notes

???Make sure beforehand that the surface where the work is to be stuck is clean and free of all dust or oily deposits.

???When applying the work to a transparent surface, such as a window, you can use a water- based pen (which can be wiped off afterwards) to mark guidelines on the reverse side of the glass, to aid in getting the work aligned properly.

???If you discover after it is stuck in place that air bubbles were trapped under the work, use a needle to puncture them. Then you can smooth out the sheet out so that it sticks securely.

(1)

For Cut Sheets

Refer to "Removing the Sheet" on page 7 to remove the sheet from the PNC-900.

For Roll Sheets

Use scissors or something similar to sever the area that has been cut from the roll sheet.

(2)

Strip away all unneeded portions from the completed work.

*You should direct that a rectangle be cut around the targeted work.

(3)

Stick application tape over the completed work.

Press down firmly on the application sheet to remove air bubbles. If you do not press firmly enough the cut area will not stick to the surface.

(4)

Carefully apply the work at the desired location, while keeping it as straight as possible. Rub over the application tape to make sure the work is firmly stuck in place. Then peel off the application tape.

4-9 When Cutting Is Completed

(1)When cutting is finished, press down the sheet loading levers and remove the sheet. (See "Removing the Sheet" on page 7.)

(2)If a blade was used, wipe the blade with a soft cloth to remove any pieces of the sheet that may be adhering to it. If a pen was used, remove the pen from the tool carriage and cap it securely.

(3)Turn off the power.

If you do not intend to use the unit for an extended period of time, you should pull the plug for the power cord out of the outlet.

* For routine cleaning, use a soft piece of cloth.

Performing a Demo Cutting

The PNC-900 is equipped with a "self-test" function to conveniently allow you to check whether or not it is capable of operating normally. Should you ever suspect that the PNC-900 is not performing satisfactorily, you should follow the steps below to perform the self-test.

* A computer is not required in order to carry out the self-test.

(1)Refer to "4-3 Installing the Blade" and install a blade holder (or pen) in the PNC-900's tool carriage.

(2)Set the pen force to the smallest possible value (the pen force slider should be at the furthest point to the left). If after the first test you feel that the sheet was not cutout clean enough, you can try gradually increasing the pen force until you have the optimum level.

(3)Hold down the key on the panel while you turn the power on.

(4)Load the sheet (or some paper), following the procedure described in "4-4 Loading the Sheet."

(5) Press the SETUP key. Demo cutting starts.

SETUP

5 SETTINGS FOR EACH FUNCTION

??? Using the Sheet Effectively

(Rotate function) ??? ROTATE Key and ROTATE LED

If there is still unused material on the right side, rotation allows you to use this remaining material effectively. This function sets the origin point at the bottom right and rotates the text (or graphics) 90??.

You have already learned of the method whereby a new user origin is set, allowing further cutting to be carried out within the remaining material. Depending on the shape and the size of characters, however, you may wish to rotate a character instead in order to cut it.

In this case, you can use the rotate function to rotate the character string "Roland" at 90??, so that the whole character string then easily fits into the available material.

Procedure

The "d" extends beyond the available material.

*If the SETUP LED is illuminated, the ROTATE LED will not light up when the ROTATE key is pressed. Press the SETUP key to extinguish the SETUP LED, then press the ROTATE key again.

The ROTATE function is also canceled when the power to the PNC-900 is turned off.

When the character string ???Roland??? is rotated by 90 ??, the X axis, Y axis, and origin change as follows:

* The pairs of arrows indicate the positive directions along the X and Y axes.

??? Plotting on Paper Media ??? PEN MODE Key and PEN MODE LED

The PNC-900 is also capable of plotting on paper media using plotter pens made by this company. You should use only thick water-based fiber-tipped pens.

Since the design of the PNC-900 differs inherently from that of dedicated plotters, it does not accommodate functions such as high-speed plotting, automatic pen changes, pen dry protection, or the like.

Procedure

(1)Refer to "Installation" in on page 6 to install a pen. (In the instructions, read "pen" for "blade holder.") There is no need to perform an operation test when in the Pen Mode.

(2)Refer to "Loading the Sheet" on page 7 to load a piece of paper in the same way as for loading a sheet. Paper with a width (horizontal dimension) between 50 mm (1-15/16") and 305 mm (12") can be loaded.

(3)

Press the PEN MODE key

(4)Plotting begins when plotting instructions are sent from the computer.

* Be sure to perform pen plotting only in the Pen Mode.

Stopping Plotting on Paper Media

Press the PEN MODE key. The PEN MODE LED is extinguished and the unit returns to the cutting mode.

Pen Replacement

Pens will eventually wear out. Should the tip become rough and produce scratchy lines, try gradually increasing the blade force (refer to page 8, "4-6 Cutting Test to Check Blade Force"). If increasing the blade force does not help, the pen should be replaced.

6 ABOUT THE BLADE

If the blade becomes dull

When the blade starts to lose its sharpness, try gradually increasing the blade force (refer to page 8, "4-6 Cutting Test to Check Blade Force").

Increasing the blade force temporarily allows the blade to perform better. However, once the blade no longer provides reliable cutting, it is worn out. Since the blade is expendable, it must be replaced as often as necessary.

Average blade life

The life of a blade is determined mainly by the amount of cutting it performs. The following table shows the average life of blades.

The total cutting length actually obtained can vary considerably depending on the thickness, toughness, and type of adhesive layer that the sheet has. Set an appropriate blade force, one that is well matched to the type of sheet and hardness of the blade, and the life of the blade will be extended. Excessive blade forces can cause the blade to wear out quickly. Care should be taken.

7 WHAT TO DO IF...

If the PNC-900 doesn't run...

???Communication parameters

???Other settings

Check the software user???s manual and set it up correctly.

The POWER/ERROR LED is blinking

If there is an error in the data downloaded to the PNC-900 from the computer, the PNC-900 generates an error (the POWER/ ERROR LED begins to blink), and cutting cannot be carried out. The error can be canceled by switching off the power. After turning off the power, check the following.

??? If you are using application software, has the correct output device been selected?

Select "PNC-900" as the output device. If this selection is not available, select any model in the CAMM-1 series (the PNC-1900/1600, PNC-1800, PNC-1100, PNC-1000A, or PNC-1000).

??? If you are using a program that you have created yourself, have correct commands been sent?

The PNC-900 is equipped with the CAMM-GL III instruction system. For details, refer to "8 List of CAMM-GL III Instructions" on page 18.

???Do the DIP switch settings match the settings made for the application software? Refer to "4-2 DIP Switch Settings" on page 5 to make the correct DIP switch settings.

???Does the connecting cable match the settings for the application software and the computer?

Refer to the operation manuals for your application software and computer to select and connect the appropriate cable.

The sheet is not cut properly

??? Are the blade and blade holder installed correctly and securely?

Install these so that there is no looseness (see "4-3 Installing the blade" on page 6).

??? Is the blade chipped?

If it is, replace it with a new one (see "4-3 Installing the blade" on page 6).

???Check if there are any dirty deposits on the blade. If dirty, remove and clean the blade.

???Make sure you are using an appropriate blade force setting.

Perform a "cutting test," then adjust the blade force slider as necessary to obtain the optimum blade force (refer to page 9, "4- 6 Cut Test to Check Blade Force").

??? If you are cutting a thick sheet, set DIP switch SW-8 to ON (heavy). (See "4-2 DIP Switch Settings" on page 5 and "Cutting a Thick Sheet" on page 11.)

The sheet slips away from the pinch rollers during the cutting process

??? Are the sheet loading levers on both the left and right sides raised?

If a sheet loading lever has not been raised, then the sheet has not been secured in place. Make sure that the pinch rollers on the left and right sides are within the boundaries of the sheet, and raise the sheet loading levers. (Refer to "4-4 Loading a Sheet" in on page 4.)

??? Make sure the sheet is parallel with the grit roller.

If the front edge of the sheet you are working with is at an angle, cut off the odd-shaped part to make it straight, then align it so that it is parallel with the grit roller.

??? If the sheet is to be advanced over a long distance, moving the movable pinch roller inward slightly can help prevent the

sheet from becoming dislodged. Also, after loading the sheet, it is recommended that you carry out cutting after first using the key to advance the sheet by the amount that will be used for cutting, and make sure that the sheet does not slip away from the stationary and pinch rollers.

???If a roll sheet is used, carry out cutting after first pulling out the amount of sheet that is to be used. The sheet is susceptible to slips when it is pulled out by the cutting process.

???Make sure that the left and right edges of the sheet do not touch the inner surfaces of the PNC-900 during cutting. Such contact may not only damage the sheet, but could also make normal sheet advancing impossible and cause the sheet to slip.

9 LIST OF DEVICE CONTROL INSTRUCTIONS

Device control instructions are used to determine the communication sequence between the PNC-900 and computer through RS-232C interface and to tell the computer the current PNC-900 state. Among them, some device control instructions set the output specifications of CAMM-GL III instructions.

Each device control instruction is organized with three letters: [ESC] , "." and one uppercase letter. Device control instruc-

tions are of two types: one with parameters and the other without parameters.

Parameters can be omitted. A semicolon ";" is used as a delimiter to separate parameters if they are input in succession. A ";" without parameters means that parameters were omitted.

If parameters are omitted, the default value is set. For a device control instruction with para-meters, a terminator needs to be input in order to signify the end of instructions. A colon ":" is used as the terminator which cannot be omitted.
