HP DesignJet 510 610 mm User Manual

							11. Press the Form Feed and Cut  key on the front panel to eject any small pieces of paper that are still in the 
paper path.
12. Reload the paper as normal (see  Loading roll paper
 or Loading sheet paper
). If you are using roll paper you 
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 heavyweight coated or matte film; this will help to force out any paper jammed 
in the paper path.
13. If the cutter seems to be causing the problem, check in  Paper types
 that the type of paper is supported by the 
printer. Try disabling the cutter from the front panel; use   →  Cutter  → Off .
You are strongly recommended to align the printheads (see  Printhead alignment
) after clearing a paper jam, as 
the problem may have caused the printheads to be misaligned.
 
						

							Ink marks on the paper
•Warped lines
 
• Blurred lines (ink “bleeds” from lines)
•Marks or scratches on glossy paper after printing•Smears or scratching on your printed paper
 
						

							Warped lines
• The paper itself may be warped. This can happen if it has been used or not been stored in the correct environmental conditions.
• For all environmental specifications, see  Environmental specifications
.
Blurred lines (ink “bleeds” from lines)
• Perhaps you have adjusted the drying time in the front-panel menu to speed up the printer output. Set “Drying  time” to  “Automatic”.
For details of drying time adjustments, see  Ink system
.
Marks or scratches on glossy paper after printing
Glossy paper may be extremely sensitive to the bin or anything that it comes into contact with directly after 
printing. This will depend on the amount of ink printed and the environmental conditions that are present at the 
time of printing. Avoid any contact with the paper and handle the print with care until quite some time has elapsed.
NOTE: Included with HP papers is a book “ Printer Tips” that includes a section on troubleshooting 
paper problems.
 
						

							Smears or scratching on your printed paper
This problem can appear on paper-based coated paper if a lot of ink is printed quickly. The paper cannot absorb 
the ink quickly enough and becomes distorted. As the printheads move over the paper, the printheads and the 
paper 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 paper. 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 the above fails to solve the problem of smears and scratching, change the paper type you are using to a non-
paper-based material such as HP Clear Film.
 
						

							Paper loading problemsThe front panel keeps indicating that paper is misaligned or incorrectly positioned.
Roll paper
• The roll paper may be loaded the wrong way. The paper should load over the roll towards you, see Loading 
roll paper
. 
• The paper may be skewed. The right-hand edge must be parallel to the blue line on the front paper 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 paper
• The sheet 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 paper
.
• The paper may be crumpled or warped or may have irregular edges.
• If you are using hand-cut paper, the edges may not form a right angle or they may be rough. Do not use hand- cut paper. Use only purchased sheet paper.
• If the paper is curled with the curl up it will be very difficult to load. It is easier to load it with the curl down
 
						

							Paper output problemsPrints fall on the floor after being cut
• Make sure the paper bin is open.
• Do not let more than twenty prints accumulate in the bin.
• Make sure roll paper is loaded correctly. If the paper is loaded incorrectly, the natural curl of the paper may cause it to miss the bin and fall to the floor.
Prints do not stack properly in the paper 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 paper in the bin.
 
						

							Image error
•Image is incomplete
Details the actions to take when the print is: blank, partial, or has suffered  clipping
.
• Printed image incorrect
Explains why the image is: 
- In one portion of the printing area
- Unexpectedly rotated
- Mirrored
- Distorted or unintelligible
- Overlaid with another image
- Does not obey Page Format and Rotate commands
• Other sources of informationLists others sources of information for image problems.
 
						

							Image is incomplete
•Output contains only a partial print•Image is clipped•Long-axis print is clipped
Output contains only a partial print
• Did you press  Cancel or Form Feed and Cut  before all the data was received by the printer? 
If so, you have ended the data transmission and will have to print the page again (you normally don’t need to 
press  Form Feed and Cut  to unload the print).
• The  I/O Setup  > I/O Timeout  setting may be too short. From the front-panel menu you can increase the 
I/O Timeout setting to a longer period and then send the print again.
• The file may be too large for the printer’s memory.
Select  Send Job as a Bitmap  in the driver’s Troubleshooting  menu (Services  tab). This may slow down print 
speed. 
Alternatively, you can install extra memory on the HP-GL/2 Accessory Card in your printer, see 
Memory.
• There may be a communications problem between your computer and the printer.  Check your interface cable.
• Check to make sure that your software settings are correct for your current page size (for example, long-axis  prints).
 
						

							Image is clipped
• This normally indicates a discrepancy between the actual printing area on the loaded paper and the printing area as understood by your software. For general advice on printing areas and page size, see  Printable area
.
• Check the actual printing area for the paper size you have loaded (printing area = paper size – margins). For  paper size and margins, see  Printable area
.
• Check what your software understands to be the printing area (which it may call “printable area” or “imagable  area”). For example, some software applications assume standard printing areas that are larger than those 
used in this printer.
• You may have asked to rotate the page from portrait to landscape on paper that is not wide enough, for  example a D/A1-size page rotated on a D/A1-size roll.
• If necessary, change the printing area in your software.
• The file may be too large for the printer’s memory.
Select  Send Job as a Bitmap  in the driver’s Troubleshooting  menu (Services  tab). This may slow down print 
speed. 
Alternatively, you can install extra memory on the HP-GL/2 Accessory Card in your printer, see 
Memory.
Long-axis print is clipped
• Does your software support long-axis prints?
• Have you specified an appropriate paper size in your software?
• There may not be sufficient memory.
Select  Send Job as a Bitmap  in the driver’s Troubleshooting  menu (Services  tab). This may slow down print 
speed. 
Alternatively, you can install extra memory on the HP-GL/2 Accessory Card in your printer, see 
Memory.
