1. INTRODUCTION

1.1 GENERAL DESCRIPTION

The Imaging Systems Group’s V8.5e Thermal Plotter is a high-sp eed plotter suitable for office or field use. Its small size and lightweight, yet rugged construction makes it durable in mobile situations. The V8.5e uses direct thermal plotting technology, so it requires no liquid or powdered ink.

Interface parameter settings and other menu functions can be accessed from either the front panel or the host computer. It is capable of printing at four speeds; 1.0, 2.0, 3.0, and 4.0 inches per second.

The V8.5e thermal plotter contains a completely new method of plotting rasterized data. Each scan of data plotted can contain as many as 64 independent intensity levels (gray scales). The thermal print head (TPH) in the V8.5e is made up of 1728 thermal heater nibs, and each one of these nibs can be heated to a different energy level, producing a dot on the thermal media of varying intensity. This type of plotting can produce high-resolution images containing many shades of gray.

The V8.5e prints in both raster and character modes, and contains a 96-character ASCII set. It interfaces with Versatec and optionally Centronics data interfaces.

1.2 MEDIA DESCRIPTION

The V8.5e uses rolled or fan-folded thermal paper or rolled film. Media width is 8.75, and 9.0 inches. The V8.5e accommodates regular thermal paper, papers with a protective top coating, as well as certain types of film media. Call your Imaging Systems Group product representative for media recommendations.

An optional fan-fold paper guide and feeder trays (which attach to the back of the plotter, and below the rackmount plotter) are available from The Imaging Systems Group which stabilizes the paper for smooth intake of fanfold papers. These options are useful in field situations or where vibration is a problem.

Default Settings

To restore the default settings of the plotter, press and hold the menu button (button 3) while powering the plotter on. The display will briefly show “dF” during the boot up sequence, indicating that the default menu items have been loaded.

Test plot

This function produces approximately six inches of plot in a checkerboard and dither pattern in Bimodal mode. Generating a test plot while the plotter is set to grayscale mode will result in a grayscale plot corresponding to the number of gray levels selected at the time. This enables the user to verify that the plotter is creating a plot image, feeding the paper correctly, and that contrast levels and media settings are acceptable. The test plot will use the current menu settings to generate the image.

1. Press Button 1 to put the plotter into OFFLINE mode.

2. Press Button 3 once. “tP” is displayed.

3. Press and hold Button 3 until the display flashes: The test plot will be generated.

Contrast

and holding

Button 3 (MENU/SAVE) Display shows:

The contrast function adjusts the density of the output. Settings range from C 1 to C 8. Settings are relative values: C 1 is the lightest, C 4 is normal, C 8 the darkest.

After performing a test plot or plot job, determine if the contrast is acceptable. If the output is extremely dark, very faint, or irregular, first check that the media setting is correct (see “Media” section of this chapter).

If the contrast needs further adjusting, change the contrast setting by starting at the lowest value, adjust the contrast upwards one value at a time, testing after each adjustment. This is particularly important when using lightweight papers or papers with unknown specifications.

CAUTION: Thermal plotting technology involves high temperatures. Incorrect media or contrast settings can

damage the printhead or other components and void the warranty. Media damage can also occur.

Speed

The speed function adjusts the speed of the plot output. There are four output plot speed settings in the V8.5e:

1.0, 2.0, 3.0, and 4.0 inches per second. The default setting is 1.0 inch per second which produces the highest

quality output. If the plot speed is erratic, or if output quality is unacceptable, lowering the plot speed will result in an improved

plot quality. Such problems may arise when data enters the plotter at a slower rate than the plot speed setting. Lowering the output plotting speed enables the plotter to match a lower input data rate and produces a smoother output plot.

When the media setting is film (LF or HF), the plotter speed defaults to 1 inch per second. When Grayscale mode is enabled, plot speed is dependent upon the level of grayscale selected.

Media

The media function adjusts the time that the printhead is turned on (strobe time) to create an image on the media based upon the media type selected. The default setting is light paper. When the plotter is set to film or grayscale mode the printhead’s requirement for strobe times is raised. This requires a slower plot speed in order to maintain the high quality level of the V8.5e.

Note: there are two preprogrammed media tables for grayscale plotting. These calibration tables can be changed for different medias by uploading new tables which can be provided by The Imaging Systems Group Inc. for virtually any approved thermal media. These tables are custom tuned to provide maximum grayscale performance on a selected media. These tables can be uploaded to the V8.5e, where they are stored in non-volatile memory until overwritten. Tables are uploaded two at a time overwriting the factory default tables stored in T1 and T2.

CAUTION: Thermal plotting technology involves high temperatures. Incorrect media or contrast settings can

damage the printhead or other components and void the warranty. Media damage can also occur.

VORSICHT: Bei der thermischen Plottertechnologie entstehen hohe Temperaturen. Ungeeignete Medien oder

falsche Kontrasteinstellungen können den Druckkopf oder andere Bauteile beschädigen und zu Verlust der Garantie führen. Auch können Beschädigungen an den Medien entstehen.

Scaling

The scaling function stretches or shrinks the plot over a 36-inch length of plot with settings being S0 through SE. The default setting is (S2). To determine if scaling is needed, plot a job of a known length and measure it. Adjustments can be made to the scaling in increments of + or - 1/16-inch over 36 inches of plot. S0= no scale, SE = +/- 14/16” over 36 inches of plot.

Note: Positive or negative scaling is selected through the Emulation menu setting.

Emulation (vertical resolution)

The emulation function adjusts the vertical resolution of the plot (along the media length). The settings are P0, n0, P3, and n3. P0 and n0 are used with 200 scans/inch of plot data. The default setting (P3) is 203 scans per inch (equal to 203 dots per inch- dpi). P3 and n3 are used for 203 scans/inch of plot data. P and n stand for Positive and negative scaling for the scaling menu. If n is selected, the scaling factors are from no scale to -14/16” over 36” of output plot. If P is selected, the scaling factors are from no scale to +14/ 16” over 36” of plot.

Note that the horizontal resolution is determined by the printhead dot density, which is 203 dpi. The plotter can emulate 200 dpi vertical resolution (E0 and n0 settings), to match the rastered host dat a (for Imperial units).

Form feed length

The form feed length function adjusts the distance that the media is advanced in off-line mode and when a remote function is sent. To form feed media, put the plotter in offline mode and press the FORMFEED/ADVANCE button

without holding

Menu settings are: F2, F4, F8, tF, PF. F2, F4, F8 cause 2”, 4”, or 8” of media to be advanced upon a formfeed. If a TOF mark is detected before the formfeed is completed the plotter will stop upon detecting the mark, or to what the PF setting is.

tF results in the plotter advancing up to 18” while detecting for the Top of Form mark on fan fold media. The topof-form setting (tF) allows the plotter to detect top-of-form marks. These marks signal the plotter to st op the form feed at a consistent distance from the perforated edge of the paper.

PF - Programmable advance past Top of Form- This feature allows the V8.5e to line up with the beginning of pages when a media whose TOF marks do not meet the V8.5e specifications.

NOTE: iSys recommends only the use of approved media in the V8.5e which has been qualified to increase plotter life and produce higher quality plots.

Once the PF feature is selected in the menu, the V8.5e will detect the media TOF mark and continue to advance the media by the amount programmed when a formfeed or end of transmission is commanded.

This feature is enabled by setting the formfeed menu to “PF” The advance range is from

01 hex --- 10 scans (approx 0.05”)

ff hex --- 2550 scans (approx 12.5”) in increments of 10 scans for each hex number.

Once the menu has been set to “PF”, the amount of advance past TOF which has been programmed into the V8.5e will be used until it is changed. The default value is 23 Hex.

To program the amount of advance past TOF, send header:

98 XY 0A (where XY is the hex# of groups of 10 scans).

If the V8.5e accepts the setup string, the display will flash

Bytes per scan

The SCANWDTH function adjusts the scan width of the plot, defined in bytes per line. The default scan width is b1 (216 bytes per scan).

Menu settings are: b1, b2, g1, g2, g3, and g4.

b1 — 216 bytes/scan (bimodal). b2 — 264 bytes/scan (bimodal). g1 — 8 gray levels per scan, 1728 bytes/scan maximum. g2 — 16 gray levels per scan, 1728 bytes/scan maximum. g3 — 32 gray levels per scan, 1728 bytes/scan maximum. g4 — 64 gray levels per scan, 1728 bytes/scan maximum.

Unless you are using RLTER (remote line terminate) commands, the plotter scan width must be set to the same byte count as the rastered data from the host. Setting the scan width higher than the byte count of the raster data does not create a wider plot. Setting the scan width incorrectly results in skewed output as the data “wraps” and finishes the scan on the next line. This condition is identifiable on the plot in Figure 7-8.

The V8.5e contains a new method of plotting raster data. Each scan of data plotted can contain as many as 64 independent intensity levels (gray scales). The thermal print head (TPH) in the V8.5e is made up of 1728 thermal heater nibs, and each one of these nibs can be heated to a different energy level, producing a dot on the thermal media of varying intensity. This type of plotting can produce high-resolution images containing many shades of gray.

Change the scan width settings by pressing the up or down arrows in the bytes/scan sub-menu.

Press and hold Button 3 until the display flashes:

Grayscale media table number

t1 - media calibration table for media 1. t2 - media calibration table for media 2.

These tables have preset values for imaging on two different medias while in grayscale mode. These medias can be changed for different medias by uploading new tables.

Setup headers for programming the V8.5e

NOTE: The V8.5E must be in PRINT mode for the setup header string to work. Numeric values shown below are

hexadecimal, not ASCII.

NOTE: All menu functions can be remotely configured by sending a setup header string from the host to the

V8.5E through the interface. The programmable advance past TOF can be programmed in a similar fashion.

NOTE: Sending a 00 hex in any of the setup string positions listed below allows the menu item to remain

unchanged. The format is as follows: Byte 1: escape code =99 Byte 2: contrast C1=11 Lightest

If the V8.5E accepts the setup string, the display will flash

If there are any errors in the string, such as an out of range value on one of the numbers, or any other errors in the string format, the plotter will not accept the string, no reconfiguration will take place,and the error LED will flash twice.

4.4 ERROR MESSAGES

1. Media Out Error: The plotter will display a small square, flashing segments and the error LED will flash. To

fix this error, reload media into the potter. Plotter must be put back online to continue plotting.

5. THEORY OF OPERATION

5.1 INTRODUCTION

The V8.5e plotter uses thermal technology to convert data from the host computer into plotted output. Host data enters the plotter main logic circuitry via the data port, and passes through the interface to the data buffer on the main logic board. Control and status signals enter the main logic board at the same time as the parallel data. The microcontroller converts the data from parallel to serial and sends the serial data to the printhead. One horizontal line or scan, consisting of a single row of dots, is plotted. The stepper motor advances the paper for the next scan. This cycle repeats until the plotted or printed image is finished.

5.2 PLOTTER FUNCTIONS AND FEATURES

Power supplies

The logic circuitry and printhead of the plotter are powered by a 5 Volt DC output power supply. The thermal printhead and stepper motor are powered by a 24 Volt, 10 Amp DC power supply. Both power supplies feature an auto-switchable input, which adapts to different voltage or frequency inputs.

THEORY OF OPERATION

Figure 5-1 Functional block diagram

Stepper motor

The V8.5e uses a bipolar, two-phase stepper motor. The motor is micro-step driven, requiring 200 full steps for one rotation of the motor shaft. There are 32 micro-steps per full step. Thus the motor makes 6400 micro-steps for each rotation.

5.3 INTERFACE

The data interface may be short line or, optionally, long line (see “Interface setup” in Chapter 3, Installation for details.) The plotter is compatible with either the Versatec Greensheet or (optionally) the Centronics interface (see Appendix A). Table 5-1 shows the active level for the plotter status signals.

Interface timing and signals

The ready signal indicates the plotter’s readiness to accept data. When READY is low, the plotter can accept one byte of data. This byte must be accompanied by a PICLK (data strobe) pulse. Table 5-2 shows the timing relationship for maximum data transfer.

Low level means plotter is ready to receive next data byte or remote function. High level indicates plotter is busy and will not accept data or remote functions.

Table 5-2 Data Transfer

Note that the plotter goes busy after receiving each byte. The plotter goes busy for longer periods during the execution of remote functions, when the input buffer is full, or when an error occurs.

Table 5-3 shows the timing relationships for the remote functions. When the input buffer receives the number of bytes necessary to plot a full scan, a write cycle is automatically initiated, causing the buffer contents to be imaged on the medium.

Table 5-3. Remote function signals

Data rates

The plotter accommodates a wide range of data rates. The speed of the plotter can be set to 1.0, 2.0, 3.0, 4.0 inches per second. To achieve a consistent plot rate at a certain speed setting requires minimum data rates. If data rates are inconsistent, and lower than these minimum rates, that plot speed will not be sustained. Table 5-4 shows the minimum data rates at the four speed settings.

Speed of plot Minimum data rate

1.0 inch per second 44 KB/sec

2.0 inches per second 88 KB/sec

3.0 inches per second 132 KB/sec

4.0 inches per second 176 KB/sec

Table 5-4 Minimum data rates

As with all thermal plotters, slower speeds produce the highest quality output. Plotting at a speed too high for the data may result in the deterioration of fine details. Stops and starts caused by inconsi stent data rates may also result in a lower quality output.

Scan width

Scan width settings sent from host software can specify the number of bytes of data that will be plotted on a line. The maximum setting that data can be rastered to is 264 bytes per scan.

NOTE: The thermal head holds a maximum of 216 bytes of data. When the plotter is set to 264 bytes per scan, the first 216 bytes of data from the host are loaded into the thermal head to be plotted and the last 48 are discarded.

For rastered data less than the current byte count setting on the plotter, the scan may be terminated at any byte count by a RLTER command. If a RLTER command is asserted, the scan is terminated and the plot continues on the next line.

Vertical resolution

The vertical resolution of the plot can be changed from the default value of 203 dpi (n3or P3) to 200 dpi (n0 or P0, also known as Imperial unit setting). See “Emulation”, in Chapter 4, Operation, for information on control

panel settings. The plotter emulates the 200 dpi resolution by stretching the plot length. This is accomplished by inserting micro-steps at regular intervals, so that 200 scans cover one inch of plot.

Scaling

The scaling function either stretches or shrinks the plot by removing or adding a micro-step at a set interval. Adjustments can be made to the scaling in increments of +/- 1/16” over 36” of plot length. The interval is determined by the scaling setting on the control panel. See “Scaling” in Operation, Chapter 4, Page 4-9, for information on control panel settings.

Print mode

When the host asserts the PRINT mode signal, the plotter can generate ASCII characters. Table 5-5 shows the timing relationships for print mode signals.

mode. When signal is high, plotter is in print mode.

Operation

Table 5-5. Mode signals

ASCII characters are produced as plot patterns on a 16 x 20 dot matrix through the use of a Character Generator ROM. When one complete print line of ASCII-coded data is received, the data is converted into plot patterns. Each character line is executed over 20 plot scans.

5.4 THERMAL PRINTHEAD

The thermal printhead is comprised of a row of 1728 heater elements (nibs). Each bit within a scan addresses an individual nib. Plot patterns are generated one scan at a time, each scan consisting of a horizontal row of dots. A nib produces a dot if the corresponding scan bit in the buffer is a logic level “1”. Nibs in the printhead are heated, causing a thermo-chemical reaction with the coating on the media. The intensity or period for which the nib is heated is called the burn strobe.

Automatic Head Temperature Feedback

The thermal printhead rises in temperature as it plots images on paper, thus, less energy is required to activate each nib as the plot proceeds to create an image of the same intensity. A thermistor embedded in the head measures the head temperature and provides feedback information to the main logic board. The main logic board decreases the burn strobe accordingly to keep the contrast of the plotted image consistent as the plot proceeds. If the printhead temperature reaches 60º C, the Automatic Head Temperature Feedback circuit stops the plotter in order to let the head cool down. The control panel display reads hot (Ht) and the error light flashes. When the thermistor measures that the printhead temperature has cooled to 45º C, the plot resumes with no loss of data.

Film media

When the plotter is set to film mode, the strobe length is increased to accommodate the thicker media. The plot speed is set to 1.0 inch per second to allow the longer strobe length and to maintain plot quality.

5.5 MEDIA SENSORS

The top-of-form (also known as the “I-mark”) sensor and the media sensor are contained on a media sensor board. The top-of-form sensor consists of a focused infrared beam and receptor that reacts to black top-of-form marks. The receptor sends a “stop form feed” command to the logic circuitry if a mark stops the beam from reflecting back into the receptor. The paper sensor consists of an unfocused infrared beam and receptor. If the receptor receives enough reflected light, the receptor sends no command. If the reflected light is below the required level the receptor sends a “media out” command to the logic circuitry and plotting stops. The “no media” indicator is displayed on the control panel.

6. MAINTENANCE

6.1 MAINTENANCE NOTE: Do not attempt to repair or modify any component of the V8.5e. If a component fails, it may be replaced

free of charge in accordance with the warranty procedures in this manual. Attempting unauthorized repairs or modifications will void the warranty and invalidate safety approvals.

WARNING: There are voltage hazards inherent in the printhead power supply and AC input wiring. Take reasonable precautions to avoid electrical shock. Never service any electrical component of the V8.5e while the power cord is connected. Severe electrical shock may result.

CAUTION: Take care not to discharge static into the plotter. This may cause damage to integrated circuits or other electronic components. Dissipate static by wearing a static disipating wrist strap, before using tools on the plotter or touching internal components.

WICHTIGER HINWEIS: Versuchen Sie nicht, irgendwelche Bauteile des V8.5e zu reparieren oder zu modifizieren. Falls ein Bauteil versagt, kann es gemäß den in diesem Handbuch enthaltenen Garantiebedingungen kostenfrei ersetzt werden. Bei nicht genehmigten Reparaturen oder Modifizierungen erlischt der Garantieanspruch und Sicherheitszertifikate werden ungültig.

WARNUNG: Am Druckkopf und am Wechselstromanschluss bestehen gefährliche Spannungen. Lassen Sie angemessene Vorsicht walten, um Stromschläge zu vermeiden. Ziehen Sie den Netzstecker, bevor Sie an irgendwelchen elektrischen Bauteilen des V8.5e arbeiten. Andernfalls kann es zu erheblichen Stromschlägen kommen.

VORSICHT: Vermeiden Sie statische Entladung am Plotter. Dies kann Schäden an den integrierten Schaltkreisen und anderen elektronischen Bauteilen verursachen. Leiten Sie statische Elektrizität ab, indem Sie ein AntistatikArmband anlegen, bevor Sie am Plotter mit Werkzeugen hantieren oder interne Bauteile berühren.

This symbol indicates an area of possible concern due to static discharge into the circuitry. When you see this symbol in the manual, please observe proper static precautions to minimize damage to the circuitry.

6.2 MAINTENANCE GUIDELINES

In order to minimize the complexity of troubleshooting and repairs, the V8.5e plotter is composed, wherever possible, of field replaceable units (FRUs). The Imaging Systems Group Inc. does not recommend troubleshooting at a component level, but rather to the level of these FRUs. This chapter and the troubleshooting chapter of this manual follows this approach, resulting in faster and easier repairs. Replacing or repairing FRUs, rather than smaller components, minimizes down time and simplifies procedures.

Use caution while troubleshooting the V8.5e. Turn the power off and unplug the power cord to prevent electrical shock.

Seien Sie bei der Fehlerbehebung am V8.5e vorsichtig. Schalten Sie den Strom ab und ziehen Sie den Netzstecker, um Stromschläge zuvermeiden.

6.3 REGULAR MAINTENANCE

The V8.5e thermal plotter is engineered to require minimal preventative maintenance. If the thermal printhead and platen roller are cleaned regularly, and the plotter is kept free of debris, extra maintenance should rarely be required.

This minimal preventative maintenance is the customers responsibility. Damage to the plotter that has in The Imaging System Group’s opinion resulted from neglect or misuse will not be covered under warranty.

CAUTION: No parts of the V8.5e require lubrication. All bearings are sealed and self-lubricating. These bearings

must be replaced in pairs if one fails by authorized repair depot.

VORSICHT: Kein Teil des V8.5e erfordert Schmierung. Alle Kugellager sind geschlossen und selbstschmierend.

Diese Lager dürfen nur paarweise durch eine autorisierte Servicewerkstatt ausgetauscht werden, falls eines defekt wird.

Cleaning the thermal printhead

After prolonged use, the thermal printhead picks up fibres from the media passing under it. These fine fibres collect and compact on portions of the printhead, blocking the contact it makes with the paper during a plot and causing faded patches. Poor contact between the printhead and paper may also cause the affected heating elements (nibs) to fail prematurely because of improper heat dissipation to the paper.

Clean the printhead every time you install a new roll of paper or film.

1. Turn the plotter power off.

Figure 6-1

2. Moisten (do not soak) a soft, lint-free cloth or cotton swab with 99% pure isopropyl alcohol. Rub gently along

the length of the printhead, removing any buildup of residue on the printhead.

3. Allow the alcohol to evaporate completely before using the plotter.

CAUTION: Do not touch the printhead with your fingers or other objects. Skin oil will contaminate the printhead,

which diminishes plot quality and shortens the life span of the printhead.

VORSICHT: Den Druckkopf nicht mit den Fingern oder irgendwelchen Gegenständen berühren. Fett oder Öl

verschmutzt den Druckkopf, wodurch die Druckqualität vermindert und die Lebensdauer des Druckkopfes verkürzt wird.

Cleaning the platen roller

After prolonged use, the platen roller picks up fibres from the paper passing above it. These fine fibres collect and compact on portions of the platen roller, creating bumps. The uneven surface of the roller may cause the printhead to contact the passing paper unevenly, producing a blotchy or faded plot.

Clean the platen roller when it appears dirty, or after approximately three rolls of paper or film have been plotted. Lightly wipe the roller with a soft, lint-free cloth moistened in 99% pure isopropyl alcohol, turning the roller as

necessary to remove paper fragments and dust.

Replacing the fuse

The fuse is located in a clip next to the AC receptacle. Figure 3-2.

1. Unplug the power cable from the AC receptacle.

2. Insert a small screwdriver into the slot on the fuse clip to release it from the AC receptacle.

3. 3. Remove the fuse from the clip. Replace the fuse and insert the clip.

WARNING: Replace only with a fuse of identical specifications. Other fuses may cause a fire hazard. See

Chapter 2, Specifications, for fuse specifications.

WARNUNG: Beim Auswechseln der Sicherungen nur solche mit gleicher Spezifikation verwenden. Andere

Sicherungen können Brände verursachen. Siehe Kapitel 2, Spezifikationen, hinsichtlich der Spezifikation der Sicherungen.

WARNING: Consistent damage to the plotter AC fuse indicates a serious problem and should be repaired

immediately. Contact your authorized service center.

WARNUNG: Andauernder Ausfall der Wechselstromsicherung des Plotters verweist auf ein ernstes Problem, das

sofort behoben werden sollte. Nehmen Sie Kontakt mit ihrer autorisierten Servicewerkstatt auf.

7. TROUBLESHOOTING

7.1 INTRODUCTION

This chapter provides a list of problems that may be encountered with the V8.5e, and gives possible causes and solutions for these problems.

To use this chapter, locate the problem from the list. Follow the steps in order, referring to Chapter 6, Maintenance, where necessary.

7.2 PROBLEMS

Plotter does not plot

Possible causes: Plotter has no paper or film

Lid is not securely closed Thermal printhead is overheated Latch pins need adjustment

Solutions:

1. Check the media supply. Install more media if necessary as described in Chapter 3, Installation.

2. Check that the media is installed correctly and the plotter lid is securely closed. The top of the lid should be

flush with the top of the side panels.

3. If plotting has stopped in mid-task, the printhead may be overheated.

Do not intervene. The plotter will resume plotting from where it left off with no loss of data when the printhead has cooled sufficiently.

When the printhead temperature reaches 60ºC, the plotter stops and asserts a “busy” signal to the host. Plotting resumes when the head temperature has cooled to 45ºC. This prevents printhead damage caused by overheating.

4. If the lid does not close securely, or if the head pressure is too low, contact your authorized service center.

Plot has vertical white stripes

Figure 7-3 Plot with vertical white stripes

Possible causes: Lid is not securely closed

The printhead is dirty Some printhead nibs are burnt out

Solutions:

1. Check that the media is installed correctly and the plotter lid is securely closed. The top of the lid should be

flush with the top of the side panels.

2. Clean the printhead as described in Chapter 6, page 6-3.

3. The thermal printhead has one or more burnt out nibs so it must be replaced. Contact your authorized service

center.

Plot is blotchy or faded

Figure 7-4 Blotchy or faded plot

This problem originates from inconsistent printhead pressure across the platen roller during plotting.

Possible causes: Lid is not securely closed

Latch pins need adjustment

Solutions:

1. Check that the media is installed correctly and the plotter lid is securely closed. The top of the lid should be

flush with the top of the side panels.

2. If the plot is fading on one side, test by pressing down on that side of the lid while the plotter is plotting. If

this helps, the latch pin needs to be adjusted on that side. Contact your authorized service center.

Plot contrast is weak

Possible causes: Lid is not securely closed

Latch pins need adjustment Media setting is incorrect Contrast setting is too low 24 V power supply is malfunctioning

Solutions:

1. Check that the media is installed correctly and the plotter lid is securely closed. The top of the lid should be

flush with the top of the side panels.

2. If the lid does not close securely, or if the head pressure is too low, contact your authorized service center.

3. Check that the media setting is correct. See Chapter 4, page 4-8.

4. Adjust the contrast setting as described in Chapter 4, page 4-6.

Plot has black vertical lines

Figure 7-6 Plot with black vertical lines

Possible Cause: One or more bits in each byte going to the plotter are “stuck high”. Solution:

1. If your plotted output from the host shows these lines, run a test plot. If the lines are not present on the test

plot, the problem originates with the host data. Check the interface data cable from the host and replace it if necessary.

Plot is wrong length

If you suspect that a plot is the wrong length, plot a job of a known length and measure it. Possible causes: Paper is not moving freely

Scaling is incorrectly applied Vertical emulation is incorrectly applied

Solutions:

1. Check the media feed path. Ensure that the paper is installed correctly and that the paper feed is not

obstructed.

2. Adjust or reset the scaling setting as described in Chapter 4, Operation.

3. Determine if your data requires vertical emulation and adjust the vertical resolution setting appropriately. See

“Emulation” in Chapter 4, Page 4-10.

Paper is wrinkling or tearing along one edge

Possible causes: Paper feed is misaligned

Paper is incorrectly installed Lid is not securely closed Latch pins need adjustment

Solutions:

1. Ensure that paper is correctly aligned while feeding. If using fanfold paper, you may wish to leave the paper

in the box.

2. Check that the paper is installed correctly (see “Media Installation” in Chapter 3, Installation) and the plotter lid

is securely closed. The top of the lid should be flush with the top of the side panels.

3. If the lid does not close securely, or if the head pressure is too low, contact your authorized service center.

Plotter has no power

Possible cause: If the plotter is plugged in to a functioning outlet, then the AC fuse has blown. Solution:

1. Replace the fuse as described in Chapter 6.

Plotter display is functioning but motor does not function

Possible cause: Either the 5 V or 24 V power supply is malfunctioning. Solution:

1. Contact your authorized service center.

Can’t make changes to control panel settings

Possible Cause: Plotter is in ONLINE mode. Solution:

1. Press the ON/OFFLINE button.

Plot output speed is erratic

Possible Cause: Plotter speed is set too high. This is most likely to occur on the HIGH setting. Lowering the

plot speed enables the plotter to match the rate of data and produces a more steady output.

Solution:

1. Lower the plot speed setting on the control panel as described in Chapter 4, Page 4-7.

Burning smell during plot, or “blooming” present on output

Figure 7-7 “Blooming” plot

Possible Cause: Media setting is incorrect. The thermal printhead operating temperature is too

high and is burning the media.

Solution:

1. Change the media setting on the control panel as described in Chapter 4. If unsure of the media specifications,

start at the LT PAPER setting and then increase the setting, testing plot output after each change.

CAUTION: Thermal plotting technology involves high temperatures. Incorrect media or contrast settings can

damage the printhead or other components and void the warranty. Media damage can also occur.

VORSICHT: Bei der thermischen Plottertechnologie entstehen hohe Temperaturen. Ungeeignete Medien oder

falsche Kontrasteinstellungen können den Druckkopf oder andere Bauteile beschädigen und zu Verlust der Garantie führen. Auch können Beschädigungen an den Medien entstehen.

Form feed stops before desired length

Possible Cause: The form feed length is too short. The form feed stops before the paper sensor

can read the “top of form” mark.

Solution:

1. Adjust the FFLENGTH setting on the control panel as described in Chapter 4, Page 4-10.

Form feed does not stop at top-of-form marks

Possible Cause: The top-of-form sensor is not reading the marks. Solution:

1. Contact your authorized service center.

Plot is skewed or unreadable

Figure 7-8 Skewed plot

Possible Cause: The scan width is incorrect. Solution:

1. Adjust the scan width (byte count) in your host software to 216 bytes or less.

CENTRONICS INTERFACE BOARD

The new Centronics adapter (rev1-2) implements some improvements over the previous (rev1-1) adapter card. These include:

a. Rev 1-2 cards will accept either of the two data transfer methods described below automatically; no

switches or jumpers required. b. Reliable data transfers using up to 40 ft length of shielded cable. c. Rev 1-1 adapter cards exhibit inconsistent data transfer with newer generation PC.’s equipped with high

speed integrated Centronics parallel ports.

The following are two transfer formats that can be used with the optional V8.5E Centronics parallel adapter:

1) Standard transfer format To place the V8.5E Centronics adapter in raster mode, the following 3 bytes (hex) must be sent to the

Centronics adapter card:

Once these 3 bytes are sent, rastered plot data can be sent to the plotter as follows: V8.5E bytes/scan menu setting bytes/scan raster data

Once the V8.5E Centronics adapter is set to raster mode it will remain in raster mode until the init line of the host Centronics port is pulsed or the plotter power is cycled. This will return the adapter to print mode.

2) Enhanced transfer format For more flexibility, a 6 byte header can be sent before each scan of rastered data. This header allows

variable bytes/scan plotting. The Centronics adapter also returns to print mode at the end of every scan using this transfer method. This allows the five 1B, 4X commands or the standard ASCII control codes listed below in section 3 to be used during plotting. The format of the 6 byte header is:

1B 2A 72 XX YY 01 where XX = high byte of the

1B, 2A, 00

b1 216 b2 264 g1-g4 1728

number of bytes/scan YY = low byte of the number of bytes/scan

Example: To send a plot that is rastered to 200 bytes/scan, send the following 6 byte header before each

and every scan of 200 bytes: 1B 2A 72 00 C8 01 00C8 hex = 200 decimal for a plot consisting of 1728 bytes/scan, send 1B 2A 72 06 C0 01 06C0 hex = 1728 decimal The valid number of bytes that can be sent to the V8.5E using this transfer method is as follows: V8.5E bytes/scan menu setting valid number of bytes/scan raster data (XX YY) Specifying XX YY at values greater than those indicated will cause the V8.5E to terminate scans incorrectly.

3) 1B 4X and control characters

Other commands that can be sent to the V8.5E Centronics adapter: 1B 41 remote clear

1B 42 remote line terminate 1B 43 remote end of transmission 1B 44 remote form feed 1B 45 remote reset 1B 50 ZZ sends blank scans to plotter from ZZ = 01 hex to FF hex

NOTE: These commands must be sent when the plotter is in print mode. The commands will be ignored and

interpreted as raster data if they are sent at any other time. The V8.5E plotter also obeys standard control characters which must be sent when the plotter is in print

mode: 04 end of transmission

0A line feed 0C form feed

NOTE: Print mode on the V8.5E means that all bytes that are received by the plotter are interpreted as ASCII

characters and printed at 108 characters/line.
