OPERATION 4 4-6 V8.5e Rev 2.2.2002 Default Settings T o restor e the default settings o f 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.
4 OPERATION 4-7 V8.5e Rev 2.2.2002 If the contrast needs further adjusting, change the contrast setting by st arting at the low est value , adjust the contrast up war ds one v alue at a time, testing after each adjustment. This is particularly important when using lightweight papers or papers with unknown specifications.
OPERATION 4 4-8 V8.5e Rev 2.2.2002 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 le vel of the V8.5e . Note: there are two preprogrammed media tables for grayscale plotting.
4 OPERATION 4-9 V8.5e Rev 2.2.2002 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 ). T o determine if scaling is needed, plot a job of a known length and measur e it.
OPERATION 4 4-10 V8.5e Rev 2.2.2002 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).

Zur Behebung dieses Fehler muss neues Aufzeichnungsmaterial geladen werden. Der Plotter muss erneut online geschaltet werden, um den Plotting- Vorgang fortzuführen.
5 5 - 1 V8.5e Rev 2.2.2002 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.

5 THEORY OF OPERATION 5 -3 V8.5e Rev 2.2.2002 Stepper motor The V8.5e uses a bipolar , two-phase stepper mot or . 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.

THEORY OF OPERATION 5 5 - 6 V8.5e Rev 2.2.2002 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. T o achieve a consistent plot rate at a certain speed setting requires minimum data rates.
5 THEORY OF OPERATION 5 -7 V8.5e Rev 2.2.2002 Scan width Scan width settings sent from host software can specify the number of b ytes o f 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.
THEORY OF OPERATION 5 5 - 8 V8.5e Rev 2.2.2002 Print mode When the host asserts the PRINT mode signal, the plotter can generate ASCII char acters . T able 5-5 show s the timing relationships for print mode signals.
5 THEORY OF OPERATION 5 -9 V8.5e Rev 2.2.2002 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 gener ated one scan at a time, each scan consisting o f a horizontal row of dots.
THEORY OF OPERATION 5 5 - 10 V8.5e Rev 2.2.2002 Film media When the plotter is set to film mode , the strobe length is incr eased 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 .
6 6-1 V8.5e Rev 2.2.2002 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 accord- ance with the warranty procedures in this manual. Attempting unau- thorized repairs or modifications will void the warranty and invalidate safety approvals.
MAINTENANCE 6 6 -2 V8.5e Rev 2.2.2002 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 pre- cautions to minimize damage to the circuitry.
6 MAINTENANCE 6 - 3 V8.5e Rev 2.2.2002 6.2 REGULAR MAINTENANCE The V8.5e thermal plotter is engineered to require minimal pre vent ative maintenance . If the thermal printhead and platen roller are cleaned r egularly , and the plotter is kept free o f debris, extr a maintenance should rarely be required.
MAINTENANCE 6 6 -4 V8.5e Rev 2.2.2002 Cleaning the thermal printhead After prolonged use , the thermal printhead picks up fibr es 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 f aded patches .
6 MAINTENANCE 6 - 5 V8.5e Rev 2.2.2002 2. Moisten (do not soak) a soft, lint-free cloth or cotton swab with 99% pure isopr opyl alcohol. R ub gently along the length of the printhead, removing any buildup of residue on the printhead. 3. Allow the alcohol t o ev aporate completely bef ore using the plotter .
MAINTENANCE 6 6 -6 V8.5e Rev 2.2.2002 Replacing the fuse The fuse is located in a clip next to the AC receptacle. Figure 3-2. 1. Unplug the pow er cable from the A C receptacle . 2. Insert a small screwdriver into the slot on the fuse clip to release it from the A C receptacle .
7 7-1 V8.5e Rev 2.2.2002 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. T o use this chapter , locate the problem from the list.
TROUBLESHOOTING 7 7-2 V8.5e Rev 2.2.2002 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 mor e media if necessary as described in Chapter 3, Installation.
7 TROUBLESHOOTING 7-3 V8.5e Rev 2.2.2002 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.
TROUBLESHOOTING 7 7-4 V8.5e Rev 2.2.2002 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. P ossible causes: Lid is not securely closed Latch pins need adjustment Solutions: 1.
7 TROUBLESHOOTING 7-5 V8.5e Rev 2.2.2002 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.
TROUBLESHOOTING 7 7-6 V8.5e Rev 2.2.2002 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.
7 TROUBLESHOOTING 7-7 V8.5e Rev 2.2.2002 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: P aper is not moving freely Scaling is incorrectly applied V ertical emulation is incorrectly applied Solutions: 1.
TROUBLESHOOTING 7 7-8 V8.5e Rev 2.2.2002 3. If the lid does not close securely , or if the head pressur e is to o low , contact y our authorized service center . Plotter has no power Possible Cause: If the plotter is plugged in to a functioning outlet, then the A C fuse has blown.
7 TROUBLESHOOTING 7-9 V8.5e Rev 2.2.2002 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.
TROUBLESHOOTING 7 7-10 V8.5e Rev 2.2.2002 Figure 7-7 . “Blooming” plot P ossible 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.
7 TROUBLESHOOTING 7-11 V8.5e Rev 2.2.2002 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. A djust the FFLENGTH setting on the contr ol panel as described in Chapter 4, P age 4-1 0 .
TROUBLESHOOTING 7 7-12 V8.5e Rev 2.2.2002 Plot is skewed or unreadable Figure 7-8 . Skewed plot Possible Cause: The scan width is incorrect. Solution: 1.
