Troubleshooting
Solving Image Quality Problems
Whenever an Image Quality problem appears, it is advisable to print the Diagnostic Print. This will help you differentiate between possible Printhead errors and other problems such as incorrect frontpanel selection, driver or RIP configuration or mechanical problems. For information on solving Image Quality problems see Chapter 6, Print Quality.
The Printer does not Power ON
1.Check that the Power Cord is connected correctly to the Printer and to the Power Socket.
2.Check that the Power Switch on the BACK of the Printer is in the ON position.
3.Remove the DIMM’s Cover (See Page 8-73) and check the green
and red Status LED’s on the Main PCA. If they are both NOT lit, replace the Power Supply Unit Page 8-81.
Status
LED’s
4.Check that the Front-Panel Cable is correctly connected to the Electronics Module. Also make sure that the Front-Panel Cable is not damaged.

Troubleshooting
ALL the Front-Panel LEDs are Lit but Nothing Else
Happens
The BootROM DIMM is NOT correctly installed or is the wrong type.
1.Power OFF the Printer from the back and disconnect the Power
Cord. Reseat the BootROM DIMM (looking from the rear of the Printer, the first slot from the left - See Page 8-73) making sure that it is installed correctly.
2.If the problem persists replace the BootROM DIMM Page 8-73.
|
Troubleshooting Media Jams/Printhead Crashes |
|
If using HP Coated Media when problem occurred, please also |
NOTE |
|
|
refer to Page 1-10. |
|
|
The failure modes “media jam” and “head crash” are grouped together because in many cases a media jam causes the media to lift up into the carriage path and cause a head crash, thus causing many media jam failures to be reported as head crashes.
1.Did the media jam occur when loading media?
νIf the client has had media jams, it is common for pieces of media to get stuck in the media path. Clear the media path.
NOTE |
When clearing a media jam, sometimes media is stuck in the |
|
paper path. To clear this, you must lift the media lever and insert |
|
thicker media into the paper path to push out the media that is |
|
still stuck there. |
|
|
2.Is the customer using non-HP media?
νThe use of non-HP media can easily be the cause of media jams and head crashes (especially head crashes because HP media is specially formulated to avoid cockle, one of the primary causes of head crashes). If the media is not HP approved, advise the customer to use HP media and check to see if the problem is now solved.
3.The Carriage is at the incorrect height in relation to the Center Platen. Adjust the carriage to the correct height Page 5-18 and try to load the media again.
4.Check that the Vacuum Fans work correctly - Refer to Page 1-9, Problems with Vacuum .

Troubleshooting Shutdowns |
|
If a shutdown occurs, you will get the message “Switch Power Off” |
|
followed by: |
|
ν Check Printhead Cleaner Path. |
|
ν Check Paper Path. |
|
ν Check Printhead Path (followed by (1), (2) or (3)). |
|
A shutdown in each path will require different steps to resolve the |
|
problem as explained as follows. |
|
In each case, make sure that you power OFF the Printer before |
WARNING |
|
|
attempting any procedures to resolve the problem. |
|
|
Printhead Cleaner Path
1.Open the right door of the Printer and check for any visible obstacles restricting the movement of Service Station. Manually move the Service Station, checking for smooth and free movement.
Media Path
When a shutdown occurs in the Media path, you will get the message “Switch Power Off / Check Media Path (*). The (*) will be a number, which will give an indication on where the failure occurred:
1.Open the Window and check for any visible obstacles restricting the movement of the Drive Roller. If there is a wrinkled mass of media inside the paper path, lift the Pinch wheels (using the Media Lever)
and clear the obstruction. If you cannot reach the media remove the Entry Roller ( Page 8-104) to gain better access.
2.If this shutdown happens at the end of a Roll of Media, it could be because the media is stuck firmly to the Roll. Lift the Pinch wheels (using the Media Lever) and pull the media clear.
3.Perform the Media Axis Test Page 4-12.
Printhead Path
When a shutdown occurs in the Printhead path, you will get the message “Switch Power Off / Check Printhead Path (*). The (*) will be a number, which will give an indication on where the failure occurred:
1. Switch the Printer OFF from the rear and open the window.
HP DesignJet 5000 Series Printers Service Manual |
1-7 |
Troubleshooting
2.Look in the area where the Printer was printing at the time of the jam, this is where the media is most likely to be jammed.
3.Raise the media load lever.
4.Carefully remove any of the jammed media which you can lift up and out from the top of the Printer.
5.Carefully pull the rest of the roll or sheet down and out of the Printer.
6.If you are using a roll of media, trim the media with a knife as shown in the User’s Guide.
7.Reload the media.
8.Switch the Printer ON.
9.If there is some media left behind in the media path, loading paper can become difficult. This can be cleared by loading a rigid paper type through the Printer media path.
10.If you have image quality problems after a paper jam, this could indicate that the Printheads have been moved from their correct position in the Carriage. To correct this perform Printhead Alignment - Refer to the User’s Guide.
PWM Shutdown (1) and Energy Shutdown (3)
1.Clean Slider Rods and Apply Oil along the complete axis of the Slider Rods with the User’s Slider Rods Lubrification Kit Page 9-8. After applying the Oil, perform the Scan-Axis Test Page 4-10 and check that the values are within the given limits.
2.Replace the Scan-Axis Motor Page 8-53.
Velocity Shutdown (2)
1.Open the Window and check for any visible obstacles restricting the movement of the Carriage Assembly. Try and move the Carriage Assembly manually, checking for smooth and free movement.
2.Check that the Encoder Strip is clean. If necessary, clean the Encoder Strip using a damp cloth.

Troubleshooting
Problems with Vacuum
If you have problems loading either Roll or Sheet Media, then there could be a problem with the Vacuum Fan or Booster Fan. To verify if there really is a problem with Vacuum, try the following:
1.With the Printer ON, open the Window of the Printer and place a sheet of HP High Gloss Photo Paper (must be D-Size), aligned with the blue lines on the Center Platen. If the Vacuum holds the sheet in place, and then loads it correctly, then the Fans function correctly. If the Vacuum does not hold the sheet in place (no suction), then try the following:
νCheck that the holes in the Center Platen are NOT blocked.
νClean the Overdrive using the Platen Cleaning Utility Page 9-9.
νCheck that the Vacuum and Booster Fans are installed correctly.
νReplace the Vacuum Fan Page 8-96.
νReplace the Booster Fan Page 8-101.
2.If the Vacuum held the sheet in place, but couldn’t correctly load it,
then there could be a problem with the Overdrive. In this case, replace the Center Platen Assembly Page 8-110.
Vacuum suction much lower at high altitudes
At altitudes above 2,000 meters, the vacuum force holding down the media will be lower, therefore the media will not be held in place properly causing:
νInk Smearing on the Media.
νPrinthead crashes against the Media.
νCut Sheet loading problems (high probability).
νRoll Media loading problems (low probability).
To solve the problem, try the following:
νUsing the “1.3 Altitude Setup” in the Service Utilities, set the altitude to “1.3.2 2000 m or more” (see Altitude Setup 4-23).
HP DesignJet 5000 Series Printers Service Manual |

Troubleshooting
Printhead Crashes/Smears on High Density Prints
Using Coated Media
High density prints can cause cockle mainly on HP Coated Media. This causes two main problems:
1.Cockling in the borders - Because the Printer places too much ink on the Coated Media, the borders of the print become raised, causing the Printhead to crash against the media. To solve the problem, try the following:
νCheck in the Front Panel if print mode is Max. Quality. If it is selected, then change print mode to Productivity to reduce ink density.
νChange the paper margins to “Extended” in the Printer Setup menu/Page Format/Margins or in the Driver. If the customer is printing PostScript images, send them a PPD file containing the extended margins.
2.Cockling within the print - If the Printer places too much ink within the print, the media starts to ripple, causing the Printhead to smear against the media. To solve the problem, try the following:
νCheck in the Front Panel if print mode is Max. Quality. If it is selected, then change print mode to Productivity to reduce ink density.
νNever use HP Coated Media for High Density prints. As a substitute use HP Heavy Weight Coated or Heavy Weight Coated (Economy) Media.
Color differences in different HP DesignJet Printers
Color differences between one image printed on the HP DesignJet 5000 Series and the rest of the DesignJet platforms are due to the different chemistry of the 5000 series inks compared with the rest of the inks for other printers. This color variability among different HP DesignJet Series Printers has been always present. You can try to achieve consistent colors with the following:
νSelect the same color emulation settings in your Postscript Driver as the one used by the printer you want to emulate.
νSelect the correct Ink Emulation from the Printer Setup Menu/ Internal RIP Settings.

Troubleshooting
Banding at variable extreme environmental conditions
The Accuracy Calibration has been done at normal environmental conditions, therefore printing in extreme environmental conditions will cause banding because the advance of the Drive Roller does not correspond to the same conditions that the calibration was done in. To solve the problem, try the following:
νPerform the Accuracy Calibration in the new environmental conditions (Refer to the User’s Guide - Media Solutions).
Banding with unsupported Media
The Accuracy Calibration has not been done for the Media now loaded. Banding may occur because the advance of the Drive Roller does not correspond to the same conditions that the calibration was done in. To solve the problem, try the following:
νSelect the Media loaded in the “Media Options” menu and perform the Accuracy Calibration (Refer to the User’s Guide - Media Solutions).
Banding due to Ink Cartridge replacement while printing
A user has removed the Ink Cartridge while the Printer was printing, which has caused the Printer to stop. If the user does not replace the Ink Cartridge immediately, when the Printer starts to print again, a band will appear in the position where the printing restarted. This is because the wet ink interacts with the dried ink on the media causing the band to appear. To solve the problem, try the following:
νDo NOT remove the Ink Cartridge while the Printer is Printing. Only replace/remove Ink Cartridges in between Prints.
νIf the Ink Cartridge was replaced due to the “Empty” status on the Front Panel, then advise the customer to replace the Ink Cartridge when the “Very Low” status is showing on the Front Panel.

Troubleshooting
Hue shift on HP Colorfast Adhesive Vinyl media
Under high humidity conditions (approx. >65%) the colors tend to fade over time, particularly colors that require Magenta. To solve the problem, try the following:
νReduce the level of humidity (<65%) that the Printer is working in. To find the humidity level, print the Service Configuration Print (Printer Setup Menu / Utilities / Test prints / Service config).
νLaminate the prints.
Black Smearing on HP Photo Imaging Gloss
Narrow black lines can smear on this type of media, particularly if the lines are narrow and have white gaps in between them. Try the following:
νIncrease the Dry Time using the Front Panel (Refer to the User’s Guide).
νLaminate the prints.
Magenta Bleeding on HP Photo Imaging Gloss when using the Take Up Reel
Under high humidity conditions (approx. >70%) this media reduces its capacity to absorb Magenta because of this color’s particular characteristics. When an area fill with magenta is printed and then rolled onto the Take Up Reel the ink that is not completely dry moves laterally on the media. To solve the problem, try the following:
νReduce the level of humidity (<70%) that the Printer is working in. To find the humidity level, print the Service Configuration Print (Printer Setup Menu / Utilities / Test prints / Service config).
νIncrease the Dry Time using the Front Panel (Refer to the User’s Guide).
νDo not use the Take Up Reel or Bin for this media when humidity levels are high.

Troubleshooting
Loss of Gloss on HP Photo Imaging Gloss when using the Take Up Reel
Under high humidity conditions (approx. >70%) the polymer chain in the coating of this media relaxes and the drying rate decreases. If the printed media is rolled onto a Take Up Reel or is covered by another print, the contact between the two surfaces could cause blotches in the gloss. Try the following:
νReduce the level of humidity (<70%) that the Printer is working in. To find the humidity level, print the Service Configuration Print (Printer Setup Menu / Utilities / Test prints / Service config).
νIncrease the Dry Time using the Front Panel (Refer to the User’s Guide).
νDo not use the Take-Up Reel or Bin for this media when humidity levels are high.
Dry Cockle on High Density Prints Using Paper Based Media
High density prints can cause dry cockle mainly on Paper Based Media.
To solve the problem do the following:
νUse the Take Up Reel and Take Up Reel deflectors.
νSet the Printer to Productivity mode to reduce the ink density.
νSelect Coated media modes.
If the problem persists, try the following:
νLaminate the prints.
νUse a heavier media that is more suitable to high ink density, such as HP Paper based Semi-Gloss or HP Poster Paper.

Troubleshooting
Wrinkles and scratches (cockle) when using HP
Coated and Heavyweight Coated Media.
Images may be damaged if prints are not handled with care, particularly when handling wide plots. This can happen when images are placed on top of one another and there is movement between them, causing friction and loss of ink from the surface if it is not completely attached. Also, if plots are rolled up wrinkles can occur. To avoid this problem try the following:
νAlways handle plots with care.
νUse of the Take-Up Reel eliminates handling and avoids wrinkles.
νUse heavier media.
νSelect faster print modes such as Heavyweight Coated (Economy) for Media selection and/or Productivity Print mode.
νIf damage is slight, Lamination will help towhead’ defects.
νUse of Fixative Sprays immediately after printing may protect the image.
Worm marks (cockle) on part of plots on paper based media
At high temperatures and under dry conditions worm marks may occur on initial parts of plots when printing solid fill areas in medium tone colors. Try the following:
νAdvance the media manually by 15 mm.
νSelect Heavy Coated for Media setting.
νSelect Productivity mode to reduce ink density.

Troubleshooting
Drying Time Too Long for HP Studio Canvas
Under conditions of high humidity (> 70%) HP Studio Canvas retains a high amount of water and takes too long to dry, also creating problems in using the Take-Up Reel and Bin. To solve the problem try the following:
νReduce the level of humidity (<70%) that the Printer is working in. To find the humidity level, print the Service Configuration Print (Printer Setup Menu / Utilities / Test prints / Service config).
νIncrease the drying time using the Front Panel settings (Refer to the User’s Guide).
νDo not use the Take-Up Reel or Bin under conditions of high humidity.
Media Skew when Printing a Banner Plot
When printing banners, media skew occurs. This is particularly noticeable in the first plot when media is not perfectly aligned. To solve this problem do the following:
νUse extended margins for banner plots (Refer to the User’s Guide).

Solving Media-Handling Problems
HP Designjet Printers minimum media size is A3 in portrait mode.
The Front Panel Keeps Indicating that Media Is Misaligned or Incorrectly Positioned
νThe roll may be loaded the wrong way. The paper should load over the roll toward you.
νThe media may be crumpled or warped or have irregular edges.
νThe paper may be loaded at an angle. The right-hand edge must be parallel to the blue line on the paper entry roller.
Ensure that the paper is wrapped tightly on the roll. This is a very important step to remember because if this is not done, the media may be loaded at an angle, causing the media to be rejected.
νPerform the manual alignment procedure (Refer to the User’s Guide).
νCheck that the paper is correctly loaded onto the spindle.
νIt must be loaded with the right-hand edge against the blue perforated line on the Printer.
νAlign the media against the trailing edge coming out of the Printer.
νThe media may be crumpled or warped or may have irregular edges.
νIf you are using hand-cut media, the edges may not form a rightangle or they may be rough. Do not use hand-cut media. Use only purchased sheet media.
νIf the media you are trying to load is very slippery, hold the media with both hands, and gently push the media into the Printer until it buckles upwards in the middle, this will help the Printer to load it.
νIf the Overdrive is covered in dust, it will have problems picking
up the sheet media during the load process. Clean the Overdrive using the Platen Cleaning Utility Page 9-7.
νThe 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.
νIf 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.
