Plotter Calibration

Note: Plotter calibration procedure (ROM 2.066 and higher). To find out which ROM version you have, just turn the plotter on. The keypad screen will show the ROM version.

Material needed: One yard ruler. Always use the same ruler for calibration, there is inconsistency from one ruler to another.

Calibration Procedure:

1. Disable the roller from the plotter keypad, press: Setup, Adjust, Enables, Roller, Disable, Enter. Return to the main menu with the Exit/Cancel key. For the power default question, answer Cancel/Exit.

2. Adjust your media size, as you would do for a standard plot: Setup, Media, etc...., then ask the plotter to draw its calibration rulers: From the main menu: Action, Tests, CalPlot. At this point, the plotter should be drawing its X and Y rulers.

3.   Cut and unload the paper, and calculate (in inches) the length of "n" marks on the paper (n varying depending on your ruler length) both in the X and Y direction.

  For example, you measure 19.23 inches for 20 marks in the X direction.

4.   Divide the calculated value by the number of marks you base your calculation on. For our example, in the X direction, it will be 19.23 inches / 20 marks = 0.9615. This result should usually fall between 0.90000 and 1.10000.

5.   Enter the new calibration value, be careful to always end the input of those values by Enter (Not Cancel/Exit). From the main menu: SetUp, Adjust, Sizing, Calibrate. Then the plotter will ask you for both the X and Y calculated values. First enter the number before the decimal point (Should be 0 or 1), then Enter, followed by the fractional part of your calculation (padding with zeros). Repeat this operation for the Y value. If you don't want to change one of  the two calibration values, simply press Enter, the value will remain unchanged. (If ever the plotter asks you if you want to keep the value as a power-up default, press Enter).

6. Repeat step 1 through 4 until you get the resolution you want.

Once the calibration procedure is terminated, turn the power off, put it on again (so it puts the roller On again).

How to solve a frame gap

If you are experiencing a gap between frames, verify the following:

1.   Plotter is leveled properly ( See chapter 8 of your Guide to Operations "Aligning the Plotter"). 

2. Paper is taut, tight and square off the feed roll.

3. The Chart wheels are positioned at an equal distance from the left and right edges of the paper.

4. Assure the Grit Shaft does not have any paper residue or any other foreign material such as vinyl or glue, stuck to it.

5. The Dancer Bars are not sticking adding weight to one side of the paper.

6. Use good quality paper. Poor quality paper will stretch or wrinkle easier causing poor tracking and performance.

7. Try placing the Chart wheels on different positions across the plotter.

8. After a while plotting, the pen may not have enough dark ink causing the sensor not to read the sensor marks properly.

9. Put a white label under the sensor, under the paper so as to increase the contrast between sensor and paper.

10. Sensor is adjusted properly  (see bulletin # 120).

If all of the above has been verified, and if you are still experiencing problems, then most likely the sensor is bad and it must be replaced.

Stylist 2000 Roll feed Parameters

Rollspd

When this option is selected, the user is prompted to enter a new Slow Speed and a new High Speed.  These values are the low and high power settings applied to the roll feed motor during frame advances and loop feeds.  First, the roll feed power is set to the low setting to roll up the front loop.  When the paper is taught between the take up roll and the grit shaft, the power is increased to the high setting.  The slow power to start to move the grit shaft and the frame advance stops after the paper is taught.  It should be decreased only if the paper snaps hard when it becomes taught.  The high setting should not have to be changed.

            Slow Speed: Default = 50 Range = 1 to 99 (power setting)

            High Speed: Default = 90 Range = 1 to 99 (power setting)

Grit shaft

When this option is selected, the user is prompted to enter a new Variable.  This value is proportional to the power setting applied to the grit shaft motor during frame advances and loop feeds.  During a frame advance or loop feed, the roll feed motor needs to do all the pulling off the back roll.  Power is applied to the grit shaft motor only to help the roll feed motor turn it.  This value should be increased only if the roll feed motor stalls and the frame advance does not complete.  It should be decreased only if the grit shaft gets ahead of the roll feed.  That is, a front loop appears (the paper is not taught) between the take up roll and grit shaft when paper is being pulled onto the take up roll.

XRtspd

When this option is selected, the used is prompted to enter a new XRtspd.  This value is the maximum speed the grit shaft will go when it returns to lower left at the end of a frame advance or loop feed.  The speed will be the lower of XRtspd and the current speed.  This value should not have to be changed.

AloneX

When this option is selected, the user is prompted to enter a new AloneX speed.  This value is the initial power setting applied to the grit shaft motor to overcome friction so the roll feed motor can start to turn it.  It is not enough power to start turning the grit shaft by itself.  This value should be decreased only if the grit shaft starts moving before the paper is taught ) roll feed motor has not pulled all of the front loop).  This value should be increased only if the roll feed motor does not have enough power to start to move the grit shaft and increasing the Rollspd slow speed causes excessive snapping of the paper.

Lost of registration in the Y-axis

Verify the following:

1. Y belt is not lose or cracked.

2. Pen is seated correctly into the pen flange.

3. Pen jaw does not have any side play.

4. All the set screws are tight in the Y-axis motor pulley.

5. The Y-axis motor drive belt is not lose or worn. You can measure the Y belt tension by moving the carriage all the way to the right end plate. The Y belt should be firm and taut, but not stretched. With a spring force gauge, measuring from the center of the machine, belt deflection should be approximately 1/8 inch with 180-220 grams of force applied (see figure below).

If after verifying the above, the problem continues, then suspect a bad servo motor or a logic board.

How to adjust the frame sensor

1. Turn the sensor vertical height adjustment screw clockwise, lowering it to within 1/8 inch (1/4 cm) of the paper (see drawing on the next page)

2. Select the media size (see page 6 - 3 of your Guide to Operations).

From the plotter main menu:

3. Press Action (F3)

4. Press Tests (F2)

5. Press Sens Tst (F4)

6. Press Mark (F1)

7. The plotter should then draw a one inch mark, at the paper edge.

8. Using the Scan (F4) routine from the keypad, turn the adjustment screw counterclockwise until the beep sounds each time the mark passes under the sensor.

9. Start counting turns of the screw, and continue raising the sensor until the beep is not heard any more.

10. Note the number of turns since counting, divide that number by two, and turn the screw clockwise that many turns.

11. The sensor should now be in the middle of the operating height range.
