Configuring the Plotter
(Instructions ' User's Guide, chapter 2, w Reconfiguring the plotter.) The User's Guide describes how to D Switch Interface Ports D Configure the following settings using a setup sheet : Language of demonstration plot and setup sheet Baud rate and parity of serial interface Graphics language HP GL timeout period Plot orientation (rotate and mirror) Line merging Pen palette settings (width and density)

An example of a setup sheet is given on the following page.

Verifying Plotter Operation
The plotters contain several types of internal operational checks and tests to ensure that the plotter is properly functioning and to help identify problems if any are detected.

Power On Self Tests
Whenever you switch the plotter on, it automatically performs a series of internal self tests and mechanical initialization sequences. If a failure occurs, an error is indicated on the front panel LEDs. You can perform a failure analysis by interpreting the LED error code. (Details ' chapter 8.)

Demonstration Plot
You can check proper plotter operation by plotting and examining the demonstration plot, which is resident in the plotters. This plot shows different plotter capabilities including pen line widths and shading. You can set the demonstration plot, to plot in any of the languages listed in the Language box of the setup sheet on the following page.

Preventive Maintenance

41

Cleaning the Plotter
To maintain the plotter in good operating condition, keep it free of dust accumulation, ink, and other contamination. Cleaning intervals are determined by the plotter environment and by the types of plotter supplies used. As with any precision electronics equipment, proper maintenance will help to ensure reliability and prolong product life. WARNING Disconnect the plotter from the power source prior to performing any maintenance. DO NOT allow water to run on to electrical components or circuits, or through openings in the enclosure, as this can create a shock hazard leading to death or injury.

General Cleaning
Proper general cleaning should include the following: 1 Blow away dust accumulation with compressed air if available. 2 Clean the outer surface of the plotter with a damp sponge or cloth. Use a mild soap and water solution if necessary. Do not use abrasive cleaners on the window. 3 Wipe the plotter dry with a soft lint free cloth.

Cleaning the Drive Roller
Due to the ink's reflectance, ink spilled on the roller can disrupt the plotter's edge sensing function. To remove any ink from the roller, perform the following procedure: 1 Connect the plotter to the ac power source. 2 Switch the plotter ON and wait for it to finish initialization. 3 With the window closed and no media loaded, press Form Feed repeatedly until the stained area of the drive roller is positioned at the top where it can be cleaned. 4 Turn the plotter OFF, disconnect it from the ac power source and raise the window. 5 Apply any common household cleaning solution to a soft, lint free rag and apply it to the drive roller surface. 6 Thoroughly clean the roller surface. 7 If other areas of the roller have been stained by ink, repeat the above steps. 8 Allow the drive roller to dry. 9 Lower the window, reconnect the plotter to the ac source, turn the plotter on, and load paper to test that no ink reflections disrupt operation of media loading.

Loading the Media
Entry Platen
The media load path begins with the entry platen, which provides a loading surface. (Illustration ' page 10 23.) When you assemble the plotter, it is important to correctly position the entry platen to ensure that the dashed lines exactly indicate the permitted right edge loading area. The left side of the entry platen should be pressed up against the left side plate. (Details ' chapter 6.) (Loading Instructions ' User's Guide, chapter 2, w Loading media.)

Sensing Media Presence
Media Sensor
The media sensor is an optosensor and is mounted towards the right end of the entry platen. (Illustration ' page 10 23). Two articulated levers block the optical path between emitter and receiver when media is not loaded. When media is loaded, both levers are rotated, thus clearing the optical path and changing the sensor state from open to closed. This double lever system provides a leading and trailing edge sensing capability (for media length measurement) to the plotter. The media sensor is electrically connected to the main PCA. 1.

CAUTION

If you pull the media parallel to the plotter length, while attempting to clear a media jam, you could break the flags.

Gripping the Media
Pinch Arms
When you load media, it is gripped by the pinch arms. (Illustration ' page 10 27.) Pinch Arm Sensor The pinch arm sensor is an optical sensor that is attached to the right side plate. It is used to detect the position of the pinch arm lever. Linkage, attaching the lever to a sensor flag, causes the flag to block and unblock the sensor as the pinch arms are raised and lowered. The pinch arm sensor is electrically connected to the main PCA.

C3187 90000

Advancing the Media
Media Drive Mechanics
The media is advanced by the media drive (X drive) system. Components include: D Media motor (X axis motor) D Worm pinion and helical drive roller gear D Drive roller (Illustration ' page 10 23.) The main component of the drive system is a full width, 6.4 cm (2.5 inch) diameter roller with an elastomer skin. This roller directly drives the media and provides the surface that references the media to the print head. The media motor position control uses an encoder feedback loop. The encoder wheel is mounted to the motor shaft, and the optical reader is mounted inside a bell housing attached to the back of the motor.

Media Drive Accuracy
The main purpose of the media drive system is to accurately move media such that the alignment of adjacent print swaths is of high enough precision that the plotter specifications are met and print quality is maintained. The media drive accuracy (end point accuracy, or X axis accuracy) specifies how accurately a plotter can draw a line of a given length. (Specifications ' chapter 1.) The configuration plot draws cross hairs 500mm apart that you can use to measure the plotter's accuracy. (Details ' chapter 7, w Accuracy Calibration.) Contributors to the Accuracy All the above components of the media drive system contribute to the media drive accuracy. The following also contribute: D Radius variations produced by the way the media wraps around the drive roller, and the way the pinch wheels and star wheels maintain this radius D Errors in the media motor's optical encoder feedback system (this system gives feedback to the motor control circuitry) Dimensional changes in the media will affect lines drawn in both axes either during plotting or after the plot is drawn. For this reason, media other than polyester film does not support the media drive accuracy specification. Polyester film is the only media that maintains dimensional stability to within the plotter specification ranges.

Providing a Force on Top of the Media
Bail
The bail provides a normal force on top of the media. (Illustration ' page 10 25.) When the pinch wheels grip the media and the drive roller advances it, the plotter raises the bail. This enables the leading edge of the media to pass below the bail. The plotter then lowers the bail and advances the media to the overdrive roller. The star wheels on the bail are coated with a substance resistant to wet ink, so that they do not leave marks on the media.

Bail Lift Mechanism
The bail features an automatic lift mechanism driven by the media motor using a series of gears and actuated by the cartridge carriage. Operation (Part illustrations ' page 10 25) 1 The cartridge carriage presses down on the engaging lever. 2 The engaging lever gear and cam gear (which are always in contact) engage the drive roller gear on the left end of the drive roller. 3 The media drive system drives the drive roller, and also the cam and engaging lever gears. The auto cam, which is attached to the cam gear, turns with the gear. 4 The auto cam contacts the left bail bracket and pushes up on the bracket. As the bracket is pushed, the bail lifts. 5 The bail sensor switch opens and the resulting bail logic level is sent to the main PCA. 6 The media drive rotates the auto cam to a detent position. The detent position allows the bail bracket to rest on the auto cam after the carriage moves away from the engaging lever. 7 The media drive drives the media through the media path. 8 Once the media has passed the bail, the carriage again engages the bail lift mechanism to lower the bail.

Bail Sensor
The bail sensor informs the processor of the bail position (Up or Down). It is a mechanical microswitch located on the right side plate. (Illustration ' page 10 25)

Stretching the Media
Overdrive
The overdrive roller stretches the media slightly as it is moved through the plotter. It thus reduces bubbling and media cockle caused by media expansion due to the absorption of water based ink into the media. Even though the geometry chosen for the plotters minimizes the occurrence of this phenomena, it still could occur on very dense plots. Operation (Part illustrations ' page 10 25) The overdrive roller is geared to the media drive system and has a surface speed 10% greater than that of the drive roller. The lower star wheels on the bail provide a normal force between the media and the overdrive roller. The resulting friction force creates media tension in the area between the upper pinch wheels and the overdrive roller (the print zone). The overdrive roller is segmented into small rollers made of polyurethane. A clutch (overdrive gear assembly) is geared to the speed ratio gear (overdrive gear cluster) and drives the overdrive roller in the forward direction only.

Moving the Carriage
Carriage Drive Mechanics
The Carriage (Y axis) drive consists of a DC motor driving the carriage by means of a dual, kevlar belt system incorporating three pulleys and two tensioner assemblies. Operation (Part illustrations ' pages 10 19 and 10 21) 1 A gear pinion, pressed onto the carriage motor shaft, drives a small belt tensioned with a self compensating, spring loaded idler. 2 The small belt drives a double pulley which transfers the motor drive to the main belt. 3 The main belt is attached to the carriage via friction fit belt clamps. It is tensioned using a self compensating, spring loaded tensioner wedge and main idler. (Illustration ' page 10 15.) The belt moves the carriage along slider rods, which are part of the chassis assembly. The carriage bearing system consists of three bushings. 4 Positional feedback is obtained using a 150 line per inch linear encoder strip that is spring loaded and passes t
