Your Printer’s Main Features

The HP DesignJet 800 printing system is specially designed for medium sized work-groups in Architecture, Engineering and Construction (AEC), mechanical CAD design and Geographical Information Systems (GIS).

For the complete printing solution, HP also offers a wide range of media including HP Heavyweight Coated Paper with fade-resistant photo-quality output and HP High-Gloss Photo Paper for high-quality long-lasting prints that produce a professional look and feel. And with the HP Complementary Media Program, HP provides users with a wide spectrum of choice and flexibility in their media selection.

The HP DesignJet 800 printer comes in two sizes:

A0+/E+ size (42 inches/1066.8 mm) and D/A1 size

(24 inches/609.6 mm) models. Both models have roll-feed capabilities. The A0+/E+ size model also includes legs and a media bin.

• Ultimate Photo Image Quality and Excellent Line Quality: The HP DesignJet 800 printer delivers ultimate photo

quality for renders, maps and photographs, providing continuous tones and smooth transitions, using a

resolution of 2400x1200-dpi with

single drop, on glossy media.

HP’s color layering technology, which layers multiple color ink drops on a

The HP DesignJet 800 also produces excellent line quality for detailed CAD

true

drawings due to the fact that each one-half inch/12.7mm printhead contains 304 nozzles, producing miniscule 18-picoliter black pigmented ink drops and four picoliter color dye-based drops, that are idea for engineering, architectural and mapping applications. And for precise color and monochrome line drawings, the HP DesignJet 800 printer, ink system and media print sharp fine lines, as thin as .002-inches and ensure accuracy of 0.2 percent of the specified page length.

• Connectivity: The HP DesignJet 800 printer comes with HP-GL/2 drivers for AutoCad® and Windows. In

addition, the printer includes USB and Parallel ports and a powerful HP JetDirect 10/100 Base-TX network

card. Using the network card, the data from the user’s computer is transferred to the “virtual computer” within the HP DesignJet 800 printer and immediately frees the data from the computer while processing it quickly.

• Speed: The HP DesignJet 800 printer delivers speeds of 250ft

/hour and color CAD line drawings on bond media are printed up to three times faster than its predecessor the, the HP DesignJet 700 series printers. Because the printer contains a virtual computer and printing is continuous, data is received by the network card and quickly processes and prints using embedded processors and large memory (96MB RAM and 6GB hard disk) included within the printer.

• HP Premium Printing Material: The HP DesignJet 800 A0+/E+ size and D/A1 size printing systems accept a

HP Ink Supplies

HP Ink Supplies for your printer contain two components: printheads and ink cartridges. Your HP DesignJet 800 printer uses the following HP Ink Supplies:

• Black Ink Cartridges are HP No 10 Supplies.

• Cyan, Magenta and Yellow Cartridges are HP No 82 Supplies.

• All Printheads are HP No 11 Supplies.

Each 600-dpi thermal inkjet printhead applies thousands of ink droplets onto the paper. The printer automatically refills the printhead as it prints, enabling continuous uninterrupted printing. The ink is supplied to each printhead from a separate large capacity ink cartridge.

There is more information available in a pamphlet which comes with the printheads and in Print Times for a Selected

Print Quality.

Choosing Paper or Other Media

For best printing results, use only genuine Hewlett-Packard paper or other type of media, whose reliability and performance have been developed and thoroughly tested. All Hewlett-Packard printing components (printer, ink system, and paper/other media) have been designed to work together to give trouble-free performance and optimal image quality.

For detailed information on Hewlett-Packard paper, see Paper Types

You should also take note of some important points about paper and other types of media:

• This printer supports many types of paper. However, the quality of some images may be reduced if you do not use the correct paper for your application. For example images with large regions of intense color, where many ink drops are needed to fully saturate the color, will not print well on HP Bright White InkJet Paper. On HP Coated

paper, the same images might cause the paper to wrinkle and then come into contact with the printheads, smearing

your print and risking damage to the printhead. See Combinations of Media Type and Print Quality Selection

• Whenever you load a roll or a sheet, the printer's front-panel display prompts you to specify the paper type you are loading. It is absolutely essential to specify this correctly for good image quality. The Physical Characteristics of

Paper Types table gives you all the information you need. If paper is already loaded and you are unsure which

paper type was specified, go to the Paper Menu and press Enter, see Obtaining Roll or Sheet Paper Information

• Make sure the appropriate print-quality setting (Best, Normal or Fast) is selected. You can set the print quality either from your software or from the printer's front panel (software driver settings override any print-quality settings made on the front panel). The combination of paper type and print-quality settings tells the printer how to place the ink on the paper—for example, the ink density, dithering method, and number of passes of the printheads. For more details, see Combinations of Media Type and Print Quality Selection

• Included with this printer is the Hewlett-Packard Printing Materials catalog which gives ordering details for Hewlett-Packard paper supplies. To get the latest version of this document, contact your local Hewlett-Packard Sales and Support office.

Handling Your Paper or Type of Media

Take the following precautions when handling paper or other type of media:

• Handle film and glossy paper by the edges or wear cotton gloves. Skin oils can interact with the ink and cause it to smear.

• Although the ink systems supplied with this printer have good light fastness, colors will eventually fade or change if exposed to sunlight over a long period of time.

• Rewrap partially used rolls if they are not being used and do not stack rolls.

• Always keep unused rolls in their plastic wrappings to prevent discoloration.

What are HP Ink Supplies?

For each of the four ink colors used in the printer, there are two separate components, the printhead and the

ink cartridge

number to help you reorder the correct replacement.

Supplies:

• Black Ink Cartridges are HP No 10 Supplies.

• Cyan, Magenta and Yellow Cartridges are HP No 82 Supplies.

• All Printheads are HP No 11 Supplies.

Ink Cartridges

The Hewlett-Packard ink cartridges for your printer require no maintenance or cleaning. As long as each ink cartridge is inserted correctly into its slot, the ink will flow to the printheads. Because the printheads control the amount of ink transferred to the page, you will continue to see high-quality printing results, even when the ink levels are getting low.

The front panel notifies you when an ink cartridge’s ink level is low. You can also check the ink levels of all the ink cartridges to determine if an ink cartridge needs to be replaced, see Ink Cartridge Information

If the ink cartridge is empty, the printer stops printing. See Ink Cartridge Replacement

Printheads

The Hewlett-Packard printheads are extremely durable and do not need to be replaced every time an ink cartridge is replaced. They are independent of the ink cartridges and will continue giving excellent image quality results even if the ink cartridges are low in ink.

. These components are called the HP Ink Supplies and are coded with an Hewlett-Packard No. selection

Ink Supply Guidelines

For optimum results from your printer and the ink system, always follow these guidelines when handling the HP Ink Supplies:

• Always install the ink cartridges and printheads before the expiry date, which is on the packaging.

• Install ink cartridges and print heads in their color-coded slots.

• Follow the instructions on the front panel during installation.

• Avoid unnecessary removal of the ink cartridges and printheads.

• When turning off your printer always use the power off button on the front panel. The printheads are then parked

correctly which prevents them from drying out.

• The ink cartridges should never be removed while the printer is printing. They should only be removed when the printer is ready for you to replace them. The front panel will guide you through the removal and installation procedure. See When to Replace

CAUTION: When you first received your printer it was supplied with a set of four setup printheads installed in

the printhead carriage. These setup printheads are used for the priming of the tubes in the modular ink delivery system. Do not remove the setup printheads from the carriage without following the procedures in the Setup Poster.

Precautions

Handle the HP Ink Supplies with care. In particular the printhead, which is a high precision device and must be handled carefully.

CAUTION: Do not touch, wipe or attempt to clean the printhead nozzles

• Do not put the printhead down on the nozzles.

• Do not be rough when handling the printheads. Always

set them down gently.

• Do not drop the printheads. Proper handling will assure optimum performance throughout the printhead life.

• Do not touch the end of the ink cartridge which is inserted into the printer as there may be a small amount of ink on the connection.

• Avoid storing partially used ink cartridges on their ends.

Color Calibration

You can calibrate the ink system for the specific media loaded in your printer. Doing this ensures the printed output matches the colors of the original image as closely as possible. The printer stores the calibration data for each type of media you have calibrated it for since it was powered up. Once the printer has been powered down the next time you use it only the last calibration made will be available and it will print using this calibration data.

To color calibrate your printer, first make sure you have the correct type of media loaded and then make the following front panel selections:

Select (using the keys)

1. Ink Enter

2. Color calibration Enter

3. Calibrate Paper Enter

The printer prints a calibration pattern and scans it to create the calibration data for the type of media loaded.

If you want to check the color calibration status of your printer, make the following front panel selections:

Select (using the keys)

1. Ink Enter

2. Color calibration Enter

3. Status Enter

Then Press:

The front panel display shows what types of media the ink system is currently calibrated for.

Image Quality Problems

Your HP DesignJet 800 printer provides a full troubleshooting utility to ensure you can always quickly overcome any image problems you encounter. You should use this utility whenever you (and not the printer) perceive a problem with print quality.

Often what you believe to be a print quality problem is in fact caused by incorrect configuration of the printer for the type of image you are trying to print. Always check Configuration Correction your problem.

If a message, such as “PRINTHEADS not functional” appears on the front-panel of your printer, follow the instructions given for the particular message (see Message Descriptions

The types of problems you could possibly encounter are:

• Stepped Lines

• Incomplete Lines

• Color Accuracy

• Horizontal Banding

• Color Alignment

Whenever you see any of these problems work through the Troubleshooting Procedure replying to the questions displayed on the front-panel. This will lead you to correct remedial action required to solve your image quality problem.

Configuration Correction

Before attempting the image quality diagnostic procedures contained in this section it is important to first check that the printer is correctly configured to print what you want. Many problems concerned with image quality can be solved by correcting the way the printer is configured.

1. To achieve the best performance from your printer, only use genuine HP accessories and supplies, whose reliability and performance have been thoroughly tested to give trouble-free performance and best-quality prints. For details of HP media, see Paper Types

2. Make sure that the Type of paper selected in the front panel is the same type of paper loaded into the printer. To check this go to the Roll or Sheet menu in the front panel and press Enter.

3. To ensure the maximum print quality use HP certified media only. For details of HP media see Physical

Characteristics of Paper Types. You can also look at the web page http://www.hp.com/go/designJet for the most up

to date information.

4. Make sure that the Print quality (Fast, Normal, Best) used for your printer is correct. This is set in the Print Setup dialog box of the printer driver or in the front panel from the Set-up menu. The printer driver setting overrides the front panel setting.

5. Select Best print mode for maximum print quality.

6. For Non-HP drivers, set front panel media settings to match the media type loaded in the printer. The documentation that came with your software should provide information about media type/print quality settings.

7. If your image quality problem is color accuracy related, go to Color Accuracy

for further configuration help.

Troubleshooting Procedure

Working through the Troubleshooting procedure should always be your first action when you encounter image quality problems. Refer to the Troubleshooting Flow Chart troubleshooting procedure.

It is important that the paper loaded for this procedure is exactly that used when you encountered image quality problems,type (for example, glossy paper) . If you use a different kind of paper or a different size, you stand less likelihood of resolving the problem.

Running the Troubleshooting Utility

1. From the main front-panel menu, select the Ink menu ( ) and press Enter.

2. Select Troubleshooting and press Enter.

3. The printer first checks to see whether the printheads are aligned. Misalignment of the printheads is a common cause of image quality problems. If they are not aligned, you are prompted to accept the Printhead

Alignment. This procedure requires a few centimeters

of paper loaded and takes several minutes to perform.

for a description of the sequence of processes used to complete

NOTE: Note that you do not have to interpret the patterns printed by the Printhead Alignment routine.

4. If the printheads do not seem to require alignment, the printer prints Diagnostic Print A. See Diagnostic Print A

Interpretation for full details of how to use this diagnostic print.

Diagnostic Print A Interpretation

Diagnostic Print A

Diagnostic Print A contains several blocks of color and a block of thin black broken lines (the lines are actually very much closer than those represented here).

1. Examine the broken lines in Diagnostic Print A carefully and indicate whether there are problems with them. The sorts of problems to look for here are:

• Jaggedness or serrations in the thin lines, like this:

; the thin lines should be straight, though not necessarily perfectly aligned. The irregularities that are significant extend along the whole of the length of the lines. Shorter irregularities, arranged in columns, can be ignored at this stage.

Ignore this

black bar

2. Examine the blocks of color in Diagnostic Print A carefully and indicate whether there are problems with them. The sorts of problems to look for here are:

• White streaks or bands in the solid blocks.

3. If you indicate that there is a problem with the dashed lines in Diagnostic Print A, you are prompted to use the Advance Calibration

routine; your printer will be at step 3 of the routine (if you don’t

want to continue with calibration, press the Cancel key).

4. If there are problems in the blocks of color in Diagnostic Print A, for example white streaks or bands, the printer will try to clean the printheads that have the problem. A printhead can be cleaned up to three times this way; after that it cannot be cleaned and you will be told; the Troubleshooting routine will finish. In that case we recommend that

you try to reprint your print, and then, if necessary, start the Troubleshooting routine again. After cleaning the printheads, the printer reprints the blocks of color (but not the black lines) in Diagnostic Print A, and asks you to examine it again (as in step 1).

5. If there are no problems the first time you print Diagnostic Print A, the printer prints Diagnostic Print B. See Diagnostic Print B Interpretation

for full details of how to use this diagnostic print.

Index

1. For each color in the pattern in Diagnostic Print B, you are asked about the

Diagnostic Print B

quality—look for missing lines. If you answer that a color is defective, the printer tries to clean that printhead. If the printhead cleaning process completes, Diagnostic Print B is printed again and you are asked the same questions again.

2. Afterwards, if problems with images remain, use the Troubleshooting procedure again.

Ignore these

solid bars

If none of the patterns or blocks in the two Diagnostic Prints shows any problem, it could be that your image quality problem is caused by a wrong setting in your software, or perhaps the job should have been printed with the Print quality set to Best instead of Normal or Draft.

If the Troubleshooting routine didn’t indicate that printhead alignment was necessary, you can select Align

printheads in the Ink menu to try to solve any further image quality problems.

Advance Calibration

It is important that the paper loaded for this calibration is exactly that used for normal printing, both in quality (for example, glossy paper) and in width (for example, A0 or 36-inch). Either roll or sheet paper can be used.

The routine prints a pattern and then cuts the roll (the cutter must be set to ON - see Controlling the Cutter

) or ejects the sheet; it requires paper that is at least 65 cm/25.5 inches long and at least 50 cm/19.7 inches wide. You must then reload that piece of paper as a sheet, so that the printer can accurately measure the pattern, and make whatever adjustments are appropriate to the amount it advances between printing swaths of data. (See Loading Sheet Media

The pattern printed is solely for the use of the printer; you are not expected to relate any of its characteristics to the quality of your images.

)

1. From the main front-panel menu, with the correct paper loaded, select the Paper menu ( ) and press Enter.

2. Select Advance calibration and press Enter.

3. Select Create pattern and press Enter.

The printer prints its calibration pattern (as represented opposite) and cuts or ejects the paper.

4. Load the sheet printed side up with the dotted line at the top

(that is, rotated 90º).

5. Now select Measure pattern and press Enter.

The printer reads the calibration pattern and makes the appropriate internal adjustments.

These Advance Calibration Values

are used whenever

printing (creating pattern)

you print on the same type of media until you have used the Advance calibration twice more with different types of media.

Advance Calibration Values

The printer stores the advance calibration values of the last two different types of media used for the calibration. When you print the printer ties to match the media you have selected to the stored values. If there is a match the printer applies the stored Advance calibration values.

If the type of media you are using has not been used for either of the last two Advance calibrations the printer uses a set default values for your media.

The Restore factory option of the Advance calibration menu erases any stored advance calibration values from the printer memory. This means that until you run the advance calibration again the printer will use the factory default values for all types of media.

Stepped Lines

When you look at the image you have printed there are ‘stepped lines’ in the borders of arrows and diagonal lines. The lines should be straight with no stepping.

The following is an example of what you might see if you have problems with Stepped Lines.

To solve this problem:

1. Increase the dpi setting by changing the print quality to Best in the front panel and driver software.

2. The problems may be inherent in the image you are trying to print. Try to improve the image with the application

that generated the file.

Color Accuracy

These are the areas you should review when troubleshooting a color accuracy problem:

Configuration

Check that you are using the correct driver setting for your software. Check which ink emulation mode has been selected in the front panel; see Color Settings

Media

Ensure the media loaded is genuine HP media and the correct media type selected on the front panel and in the driver.

Color Consistency problems

• Some media may discolor or change with age. Check that your media is fresh and has been stored correctly.

• If the environmental conditions you are printing in change rapidly, you may see changes in the color consistency. By

reducing the time the print stays in extreme environmental conditions after being printed (especially very high humidity) you can reduce the color consistency problems.

• There may be color changes between images printed on your HP DesignJet 800 and other types HP DesignJet printers. This is quite normal because the other printers use different ink.

Long Term Color Bleeding (Glossy Papers)

High ambient humidity at your location could cause the colors to bleed into the paper making the lines fuzzy and bleary.

• Change the paper that you are printing with or remove the printer out the high humidity conditions.

Unknown Printhead Error

An unknown printhead error occurs when the one of the printheads is causing a problem but the system cannot detect which one it is. Whenever this happens the front panel displays this error message. The number of printheads with unknown errors will either be all the color printheads or all the printheads.

Use the following procedure to isolate the faulty printhead.

1. Select replace Printheads from the front panel.

2. Open the Carriage cover and remove ALL the Printheads.

3. Reinsert the Cyan Printhead only and close the Carriage cover and the Window.

4. Check the front panel - if the status of the Cyan Printhead is X or ? then the conclusion is that the Cyan Printhead is faulty and must be replaced. If the status of the Cyan Printhead is OK the conclusion is that the Cyan Printhead is working correctly. Repeat the process from step 1 for the other color Printheads to identify which one is failing.

If the front panel displays this message:

There is probably paper jammed in the printer. Paper jams can have various causes:

• The paper is too thick or too thin for the printer, or is otherwise not supported

• The paper is creased or misaligned or is bubbled

• Too much ink is being placed on the paper causing it to cockle or bubble

• The end of the roll of paper is glued to the core and won’t advance further

• Pieces of paper or paper powder are clogging up the cutter guide or other moving parts.

Removing jammed paper

1. Open the window.

2. Switch the printer off at the front.

3. If necessary, carefully move the printhead carriage out of the way—if possible all the way to the enclosed area on the left or the right. Which way you are able to move it depends on where the paper is jammed.

CAUTION: When moving the printhead carriage, touch only the black plastic parts.

4. If necessary, carefully move the paper cutter out of the way to the left, or to the right depending on where the paper is jammed (though if moved right it may block the paper path).

CAUTION: The cutter is easily moved by holding it as close as possible

to the guide running across the width of the printer. Be careful not to touch the metal slider bar that runs across the printer.

5. If necessary, lift the blue paper lever, to release any trapped paper. Remember to lower it again when you have finished.

6. Carefully remove any of the jammed paper which you can easily lift up and out from the top of the printer.

may need to trim the edge first, to ensure that it is straight.

NOTE: If there is still paper left in the paper path, try loading a sheet of stiff or rigid paper into the printer,

such as heavy coated or matte film; this will help to force out any paper jammed in the paper path.

If the cutter seems to be causing the problem, check in the User’s Reference Guide on the Using Your Printer CD

Media Problems

Smears or Scratching on Your Printed Media

This problem can appear on paper-based coated media if a lot of ink is printed quickly. The media cannot absorb the ink quickly enough and becomes distorted. As the printheads move over the media, the printheads and the media come into contact with each other and the printed image is smeared.

1. Press the Cancel key on the front panel; if you continue to print, the paper may damage the printheads.

2. Cancel the print job from your computer application.

3. In order to obtain better results perform the following:

• Use HP recommended media. If the image you are printing has intense color, use HP Heavy Coated Paper.

• Try to increase the print margins by relocating the image in the page from your software applications.

• If you are using ‘Media Saving Options’ from the advanced section of the HP- GL/2 Driver, try disabling one or both

the options ‘Auto Rotate’ and ‘Inked Area’.

If the above fails to solve the problem of smears and scratching, change the media you are using to a non-paper based media such as HP Clear film.

• The paper may be skewed. The right-hand edge must be parallel to the blue line on the front media deflector.

• Ensure that the paper is wrapped tightly on the roll.

• Check that the paper is correctly loaded onto the spindle, see Installing a New Roll on the Printer

Sheet media

• The sheet media must be loaded with the right-hand edge against the blue line on the printer platen and the front edge against the blue line just after the pinch rollers, see Loading Sheet Media

• The media may be crumpled or warped or may have irregular edges.

• If you are using hand-cut media, the edges may not form a right-angle or they may be rough. Do not use hand-cut

media. Use only purchased sheet media.

• If the media is curled with the curl up it will be very difficult to load. It is easier to load it with the curl down

Prints Fall on the Floor After Being Cut

• Make sure the media bin is open.

• Do not let more than twenty prints accumulate in the bin.

• Make sure roll media is loaded correctly. If the paper is loaded incorrectly, the natural curl of the media may cause it

to miss the bin and fall to the floor.

Prints Do Not Stack Properly in the Media Bin

• The printer may be too close to the end of the roll. The natural curl near the end of the roll can cause stacking problems. Load a new roll or remove prints manually as they are completed.

• If you are mixing prints or nesting sets of several different sizes, you may have stacking problems because of the different sizes of media in the bin.
