CAD Color Diagnostic Plot (Service Test 14 ' page 834)
The main purpose of this plot is to qualitatively validate the pentopen alignment. It also provides information on the cartridge performance, as it includes a nozzle checkout and area fill.

1. - Area Fill.

2. - Nozzle Checkout.
3. - VLS & Pen to Pen Alignment Primary.
4. - Pen-to-Pen Alignment Secondary.
This plot also uses a special print mode, independent of the frontpanel settings. The following are the parameters that define the print mode: D Unidirectional. D Color. D Resolution 300 dpi (addressable 600 dpi for HP DesignJet 750C Plus and 755CM model C3198B). D Swath advance = 0.32 inches (using 96 nozzles in the color pens and 192 in the black pen). D 1 pass per swath. Pentopen Alignment verification The specification for the maximum pentopen alignment error is 3.33 mils. Use the plot to calculate the error.
Pattern 3 (on the CAD color diagnostic pot) contains vertical and horizontal lines of the four basic colors (cyan, magenta, yellow and black). This is a worst case situation, which provides qualitative information. Pattern 4 (on the CAD color diagnostic pot) includes one square and horizontal and vertical lines in red (yellow plus magenta), blue (cyan plus magenta), and green (yellow plus cyan). The horizontal and vertical lines can be used to verify whether the alignment between the cartridges used to print them is within the required specification. The lines are one pixel in thickness. If the plot is printed on matte film" media the dot size is approximately 3.33 mils diameter (the same value as the alignment specification). Focus on one horizontal or vertical blue line (see figure below), that is generated by two lines of cyan and magenta. If there is a misalignment between the two cartridges, bigger than 3.33 mils, the lines will be this distance apart. In this case, there will be a white line between the magenta and the cyan, as the dots of each color will not come in contact. (The distance will be bigger than the dot size.) When there is a blue line between the magenta and the cyan, then the distance between the lines is smaller than 3.33 mils, hence, the alignment error is within the required specifications.
Dot size 3.33 mils (Film / Glossy)
Alignment error 3.33 mils In Spec (limit)
Alignment error < 3.33 mils Out of Spec

Corrective Actions

If the pentopen alignment error is out of specification: D Perform the pen alignment test using white media ' page 840. D Perform the linesensor calibration (details ' page 75) and perform the pen alignment test again. D Replace all cartridges. D Replace the carriage ' page 634. D Troubleshoot the EEROM and the Main PCA.
AreaFill Diagnostic Plot (Service Test 15 ' page 835)
This plot is intended to check the printquality performance when printing area fills. The plot presents a worst case situation for the mainink media interaction problems:

Plot in an interlaced print mode (Best), thus increasing the number of passes over the media. Set the lightness to lighter" to reduce the amount of ink used. Feathering
Ink spreads along the media fibers, affecting the edge roughness of the lines and text.
The medias does not control the dot growth. The affected media types are: D D D D Bonds. Natural tracing paper. Vellum. Translucent bond.
Some third party media types have unacceptable results.
Too large a drop volume increases the severity of the problem.
Plot in an interlaced print mode (Best), thus increasing the number of passes over the media. Set the lightness to lighter" to reduce the amount of ink used. Use HP media. Migration (Black)
In area fills, ink accumulates in the external part of the swath, where the black is more saturated.
Ink not properly absorbed by the media, and surface forces, push the black ink to the borders (due to the chemistry of the black ink). All the CAD media types except coated paper are affected.
Plot in an interlaced print mode (Best) thus increasing the number of passes over the media. Set the lightness to lighter" to reduce the amount of ink used. Increase the dry time to reduce the migration in multipass print modes.
There is a white border between black and color area fills.
There is a reaction between the inks that changes the tensional forces at the edge, causing the black ink to move away from the color. This is also a common problem for all the CAD media types except the coated media.
Plot in an interlaced print mode (Best), thus increasing the number of passes over the media. Banding
There are repetitive bands in the area fills.
The following are the main causes of this problem: D Xaxis advance error: This error causes a variation of hue between consecutive bands. The hue is constant within each band. Nozzles are misaligned from one swath to the next. D Cartridge nozzles out, weak or misdirected: These problems generate horizontal lines of different color in area fills. In this case, instead of affecting the complete swath, the problem is restricted to the particular nozzles that are failing. In both cases, drop volume can help to hide the problems. A low drop volume makes the problems more visible.
D Xaxis advance error: Perform the accuracy calibration ' page 76. If this does not fix the problem, troubleshoot the Xaxis system (mark position test ' page 844). If necessary, replace the Xaxis motor ' page 625. D Cartridge problems: Set the plotter to multipass print mode. Replace the cartridges. Check the wipers and caps of the Service Station and if necessary, replace the service station ' page 642. D Drop volume too small: Troubleshoot the pen thermal management system, the TTOE, the carriage electronics and the cartridge.

In firmware revisions A.02.09 or higher, the paper advance calibration algorithm was improved. In order to optimize its performance, modify the mark encoder so that the reference for the paper advance error compensation is more accurate.
A line or a notch is included in the middle of the mark encoder. In units that are in the range of serial numbers listed above, follow this procedure to add a line on the mark encoder. Please, verify that your unit is within the serial number ranges that are quoted above. The units produced after these ranges will have a notch in the middle of the mark encoder, so the line will not be required.
Procedure to Install the Line on the Mark Encoder
After installing firmware revision A.02.09 or higher: 1 Switchoff the device. 2 Remove the media.
10-18 Product History and Service Notes
3 Switchon the device. 4 Open the window cover and verify that the mark encoder is in the upper position on the right side of the roller platen. If the mark encoder is not in the upper position, then perform the Mark Position test ' page 844. 5 Clean the mark encoder using the cleaning wipes HP 92193N. These wipes contain isopropyl alcohol. Allow a few seconds to ensure that the mark is dry. 6 Get a sheet containing the black adhesives lines. Identify the adhesive side (you may test it on a piece of paper). 7 Trim a piece of the sheet containing one black line. 8 Place the line in the center of the mark encoder, positioning it parallel to the platen roller. 9 Using a pen, softly rub on the back of the line. 10 Make sure that the: D Line is properly stuck on the contact surface of the mark encoder D Line is continuous and not broken. 11 If this is not the case, remove the line with a tool that can not damage the mark encoder and clean it again using the cleaning wipes. Then repeat the procedure from step 6. 12 Using matte film media, perform the accuracy calibration ' page 76.

To Use the Queue to Manage Your Plots
When the Queue option in the front-panel menus is set ON (the default), the plotter stores your plots by page. One plot file may contain several pages. With queueing turned ON, you can send plots to the plotter while the current page is still printing and use the nesting feature, if required. The Queue mgmt front-panel menu provides a Page ID option which allows you to identify a page in the queue and: display its statistics prioritize it delete it replot it (Statistics option), (Move to top option), (Delete page option), (Copies option).
If you turn off queueing with pages in the queue, they will continue to be plotted (and nested, if nesting was on), until the queue is empty. For further information on queueing, see the Users Guide.
To Use Nesting to Save Media
Nesting is available with roll media only and with queueing turned ON, If you set Nest to either Optimal or In order in the front-panel menus, the plotter automatically attempts to minimize media usage by plotting pages side by side. If it is more efficient, pages may be rotated (regardless of the front panels Page format/Rotate setting). To give the plotter the best chance of nesting the most pages, it is best if you set Page format / Margins to Smaller in the front-panel menus. For further information on nesting, see the Users Guide.

To Cancel a Plot

Press Cancel on the front panel.

Cancel

The plotter advances the media as though the plot were finished. If queueing is on and there is space in the queue, the cancelled plot is placed in the queue.
To Replot or Delete a Plot
In the case of the HP DesignJet 700 only, press Replot on the front panel. You can also replot a page in the queue (including a cancelled plot) by using the front-panel Copies option from Queue mgmt/Page ID. You can delete a page from the queue using the front-panel Delete option accessible from Queue mgmt/Page ID. For further information on these features, see the Users Guide.
To Pause while Printing a Series of Plots
You can pause between two plots already sent from your computer, for example to change the media type or replace the cartridges. You can use the front panel as normal during the pause. Press Pause on the front panel.

The plotter finishes the current plot and pauses (with the Pause light on). To resume printing, press Pause again.
