Your Printer’s Main Features

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

For the co mpl ete p rintin g so lu ti on, HP al so o ffers a wide range of media incl udi ng HP Heavyweight Coated Pa per 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 Excell ent Line Quality: The HP DesignJet 800 printer delivers ultimate photo quality for renders, maps and photographs, providing co ntinuous tone s and smooth transitions, using a true resolution o f 2400x1 200-dpi wi th HP’s color layerin g techno log y, which la y ers mu ltipl e color in k drops on a single drop, on glossy media. The HP DesignJet 800 also produces excellent line quality for detailed CAD drawing s due to the fact that each one-half inch/12.7m m printhead co ntains 304 nozzle s, produci ng mini scule 18-picoliter black pigmented ink drops and four picoliter color dye-based drops, that are idea for engineering, architectural and mapping applications. A nd for precise color and monochrome line draw ings, 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 specif ied page length.

• Connectivity: The HP DesignJet 800 printer comes with HP-GL/2 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 immedi ately frees the data from the computer while processing it quickly.

• HP Premium Printing Material: The HP DesignJet 800 A0+/E+ size and D/A1 size printing systems accept a wide range of roll and sheet media fro m 24 inches/609.6 mm (D/A1 size) to 42 inches/1066.8 mm (A0+/E+ size) wide including HP Satin Poster Pa per, HP High-Gloss Photo Paper and HP Heavyweight Coated Paper. In addition, the HP DesignJet 800 printer accepts a wide range of media for technical applications.

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 Sup plies:

• Black Ink Cartridges are HP No 10 Supp lies.

• 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

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. Howev er, the quality of some images may be reduc ed if y ou do not use the correct paper for your application. For example, images with large regi ons 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, sm earing your print and risking damage to the printhead. See Combinations of Media Type and

Print Quality Selection.

• Whenev er y ou load a roll or a she et, the printer ’s front-panel display pro mpts y ou to speci fy the paper type y ou are loading. It is abso lu te ly essen tial to spec if y th is corr ect ly for good image quality. The Physical Characteris-

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

Information.

• Make sure the approp riate prin t-quality setting (Best, Normal or Fast) is selected. You can set t he print qual- ity either from your software or from the printer’s front panel (s oft w ar e driver settings overri de 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 Combina ti ons of Me di a Type and Prin t Qu al ity S el ec -

tion.

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

selection number to help y ou reorder the correct replacement . 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 Suppli es.

• 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 in k level is low. You can also c he ck th e i nk l evels of all t he ink cartridges to determine if an ink cartridge needs to be replaced, see Ink Cartridge Information

If the ink cartridge is em p ty, the printer stops pr in ti ng. See Ink Cartridge Replacement

Printheads

The Hewlett- Packard printheads are extremely durable and do no t nee d t o be re pl ace d every time an ink cartridge

Color Calibration

You can calibr ate the ink sy stem for the specific media loaded in y our p rinter. Doing this ensures th e printed o utput 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 da ta for the type of media loaded. If you want to check th e color calibration status of your printer, make the follow ing front-panel selections:

Printhead Alignment

You should have one of the following types of paper loaded before attempting to align the printheads: HP Bright White Inkjet Paper (Bond), HP Coated Paper, HP Heavyweight Coated Paper, HP High-Gloss Photo Paper, HP Satin Poster Paper or Plain Paper. If you try to do this with any other type of paper loaded, the printer will prompt you to load a different type of paper before letting you align the printhea ds.

From time to time you may be required to align the printheads to ensure maximum print quality. To select Printhead Alignment manually, make sure you have the correct type of roll or sheet m edia loaded.

There are two types of alignment: Standard which will take about 4½ minutes; and Special which takes about 11 minutes. Standard alignment is recommended for normal use and requires paper of at least A4/Letter-size, loaded in landscape mode. Special alignment should be used to correct pen to paper spacing variations which would be show by variations in vertical line quality, particularly in wide plots and fast print modes. Special alignment requires paper of at le ast A3/B-size, loaded in landscape mode. Two separate prints are made.

Then use the following front panel menu selections to start the alignment:

Configuration Correction

Before attempting the image quality diagnostic procedures contained in this section, you shou ld 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 sa me type of paper lo aded in to th e printer.

To check this go to t he Roll or Sheet menu in the front panel and press Enter.

3. To ens ure t he ma x imu m 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 f rom 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 th rough the Troubleshooting procedure should always be your first action when you encounter image quality problems. Refer to the Troubleshooting Flow Chart complete 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) and size. If you use a different kind of paper or a different size, you stand less lik elihood of resolving the problem.

Running the Troubleshooting Utility

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

2. Select T roubleshooting and press Enter.

3. The prin te r firs t ch e cks to se e whet he r the

Diagnostic Print A Interpretation

Diagnostic Print A

Diagnostic Print A contains several blocks of color and a block of thin black broken lin es (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 b y 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 indic ate 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 ro ll (the cutter m u st be set to On—see Controlling the Cutter ejects the shee t; it r equi res pape r tha t is a t least 6 5 cm/25.5 inches long and at least 50 cm/19.7 inches wide. You must then relo ad that pi ece of pa per 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 t he ma in fron t- pane l menu, with the correct paper loaded, se le ct t he Paper menu ( ) and press Enter.

2. Select Advance calibration and press Enter.

3. Select Create pattern and press Enter. The printer prints its calib rat io n pa ttern (as rep resented here) and cuts or ej ects the paper.

4. Load the sheet printed side up with the dotted line at the top (that is, rotated 90º).

) or

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 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 sto re s the ad vanc e ca li bration 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 med ia you are using has not been used for either of the last two Advance calibrations the print er uses a set default values for your media.

The Restore factory option of the Advance calibration menu eras es any stored advance calibration values from the printer memory. This means that until y ou run the advance calibration agai n 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 l ines should be straight with no stepping.

The following is an example of what you might see if y ou 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

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 med ia type selected on the front panel and in the driver.

Color Con s i s t ency problems

• Some media may di scolor or change with ag e. Check that your media is fresh and has been stored correctly.

• If the environmental conditions you are printi ng in change rapidly, you may see chan ges in the color consis-

tency. By reducing the time the print stays in extreme environmental conditions after being printed (especially very high humidit y) you can reduc e the color consistency problems.

• There may be color changes between im ages printed on your HP DesignJet 800 and other types HP Design- Jet printers. This is quite normal becaus e the other printers us e 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 from the high humidity conditions.

Unknown Printhead Error

An unknown printhead error occurs wh en the one of the printh eads 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 printh eads 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 onl y and close the carriage cover and the window.
