Print the same HP-GL/2 file
The situation describes how to produce an HP-GL/2 file  (also known as a PLT file) with the HP-GL/2 driver
installed for one printer that you intend to send to another printer.
1 . Verify that both printers have the 
most recent firmware version. See 
Update the printer firmware
on page 141.
2 . Make sure that Color Calibration is turned on. At
 the front panel of the HP Designjet Z6100, select
the 
 icon, then  Printer configuration  > Color calibration >  On.
3 . Load the printers with the same type of paper.
4 . Verify that the Paper Type setti
ng on the front panel corresponds  to the paper you have loaded.
5 . If you have an HP-GL/2 file for an HP Designjet 55
00 and you want to print it on an HP Designjet
Z6100, use the Embedded Web Server or the front panel.
● Through the Embedded Web Server: leave the color options set to  Default.
● On the front panel: select the 
 icon, and then select  Printing preferences  > Color
options  > Emulate printer  > HP Designjet 5500 Series.
For other HP Designjet printers, set both printers to match the screen colo rs (sRGB, if that is available),
as when printing with separate HP-GL/2 drivers.
The output is completely blank
If the front-panel graphi c language setting is Automatic (the default), try the other settings:
PostScript  for a PostScript file,  HP-GL/2 for an HP-GL/2 file, and so  on. Then send the file again.
When you have finished this particular print,  remember to reset the graphic language to  Automatic.
The output contains only a partial print
●If you pressed 
Cancel before the printer received all the data, you ended the data transmission and
will have to print the page again.
● The I/O timeout  setting might be too short.  This setting determines how long the printer waits for
the computer to send more data, before deciding th at the job is finished. On the front panel, increase
the  I/O timeout setting to a longer period and then  send the print again by selecting the 
 icon,
and then selecting  Connectivity menu  > Advanced > Select I/O timeout .
● A communications problem between your computer and the printer might exist. Check your USB or
network cable.
● Verify that your software settings are correct for yo
ur current page size (for example, long-axis prints).
● If you are using network software, ma
ke sure that it has not timed out.
The output is completely blank 159
Troubleshoot images
 
						

							The image is clipped
Clipping normally indicates a discrepancy between the actual printable area on the loaded paper and
the printable area as described by your software.  You can often identify this kind of problem before
printing by previewing your print. See 
Hold for preview on page 90.
● Check the actual printable area for the paper size that you have loaded.
printable area = paper size – margins
● Check what your software understands to be the prin
table area (which it might cite as printing area
or imageable area). For example, some software  programs assume standard printable areas that
are larger than those used in this printer.
● If you have defined a custom page size that has very narrow margins, the printer might impose its
own minimal margins and clip your image slightly.
 You might want to use a larger paper size.
See 
Adjust margins and layout options on page 82 .
● If your image contains its own margins, you might  be able to print it successfully by using the Clip
Contents by margins  option. See 
Adjust margins and layout options on page 82.
● If you are trying to print a very long image on a roll, make sure that your software can print an image
of that size.
● You might have asked to rotate the page to land
scape orientation on a paper size that is not
sufficiently wide.
● If necessary, reduce the size of the image or docume
nt in your software, so that it fits between the
margins
Other explanations exist for a clipped images. So me programs, such as Adobe Photoshop, Adobe
Illustrator, and CorelDRAW, use an internal 16-bit  coordinate system which means that they cannot handle
an image of more than 32,768 pixels. If you try to  print a larger image, the bottom of the image will be
clipped. To print the entire  image, try these suggestions:
● If you are using an HP-GL/2 driver, you can reduce the resolution so that the whole image requires
fewer than 32,768 pixels. The Windows 
driver includes an option called 16-bit App.
Compatibility, which reduces th e resolution automatically. The option is on the  Advanced tab,
under  Document Options  > Printer Features .
● Save the file in another form
at, such as TIFF or EPS, and open it in another program.
● Use a RIP to print the file.
The image is in one portion of the printing area
●In the software, have 
you selected a page size that is too small?
● Does your software read the image as being in one portion of the page?
The image is unexpectedly rotated
On the front panel, select the  icon, and then select 
Printing preferences  > Paper options >
Rotate . Verify that the setting is what you wanted.
For non-PostScript files: if  Nesting is On , pages are sometimes automati cally rotated to save paper.
See 
Nest jobs to save paper on page 98 .

● Depending on the software, drivers, and RIPs that 
you are using with your printer, different ways to
solve this problem exist. Refer to the  vendors user documentation for details.

The image has a wood-grain appearance
(aeroworms)
Aeroworms are wavy, horizontal band s produced by air-induced dot placement error (DPE). In extreme
cases, aeroworms give the image a wood-grain appe arance. The problem occurs most commonly on print
jobs that are set for low-quality and high-speed. It do es not occur when the custom print-quality setting is
set to “best.”
To eliminate aeroworms, select  a higher IQ print setting. See 
Select print quality on page 80.

							The paper cannot be loaded successfully
Here are a few things to check if you cannot successfully load the paper.
● The paper might be loaded at an angle (skewed or mi
slocated). Make sure that the right edge of the
paper is aligned with the half-circle on the right- hand side of the platen, and that the leading edge
of the paper is aligned with the metal bar in the platen.
● The paper might be crumpled or warped, or have irregular edges.
● If the paper jams in the paper path to the platen, the leading edge of the paper might not be straight
or clean. Remove the initial 2 cm (1 in) of paper 
from the roll and try again. This might be necessary
even with a new roll of paper.
● Make sure that the spindl
e is correctly inserted.
● Make sure that the paper is correc
tly loaded on the spindle, and that it loads over the roll towards
you.
● Verify that the paper is wound tightly on the roll.
The paper has jammed
When a jam occurs, the 
Possible paper jam message usually appears in the front panel, with one of
two error codes:
● 81:01 indicates that paper cannot advance into the printer.
● 86:01 indicates that the printhead carr
iage cannot move from side to side.
Check the printhead path
1. Turn off the printer at the front panel, then also switch off the power switch at the rear.

. Try to move the printhead carriage out of the way.
4
. Lift the paper-load lever as far up as it will go.
5
. Carefully remove any of the jammed
 paper that you can lift up and out from the top of the printer.
6. Carefully pull the remainder of the roll down and out of the printer.
7 . Turn on the printer.

							8. Reload the roll. See Load a roll into the printer on page 32
.
9 . If some paper continues to cause an obstruction with
in the printer, it can often be cleared by loading
a rigid paper type into the printer.
10 .If you find that you have print-
quality problems after a jam, tr y realigning the printheads. See 
Align
the printheads on page 71.
Check the paper path
● This problem can occur when a roll has finished an
d the end of the roll is stuck to the cardboard
core. If this has happened, cut the end of the roll  away from the core. Then feed the paper through
the printer, and load a new roll.
● Otherwise, follow the procedure described above, under 
Check the printhead path on page 163
Prints do not stack correctly in the bin
NOTE:
This topic applies to the HP De signjet Z6100 42–in Printer only.
●Paper often tends to curl 
near the end of a roll, which 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 seve
ral different sizes, you might experience stacking
problems because of the different sizes of paper in the bin.
Automatic paper-cutter does not function
The automatic paper-cutter is disabled  when the take-up reel is in use. To use the cutter on the paper,
uninstall (disable) the take-up reel  on the front panel by selecting the 
 icon, and then selecting Take-
up reel >  Disable take-up reel .
NOTE:The automatic paper-cutter feature is disabl ed for some of the heaviest media types,
because they might damage the cutter.
Take-up reel paper jammed
If the paper is severely damaged on the take-up reel  spindle core, do not use the printers cutter to cut and
remove the paper. Instead, cut the paper manually as close as possible to th e printer window, and then
remove the roll. See 
Unload a roll from the printer on page 36 .
Take-up reel does not wind
Predictably, if the  take-up reel is not winding as  anticipated, the printed output  is likely to end up on the
floor. If the printer recognizes a pr oblem with the take-up reel, it will in terrupt the print job until the issue
is corrected. If the printer does not recognize a problem, the job will continue to print. The following table
highlights possible issues and solutions.

Cannot insert the maintenance cartridge
Verify that the maintenance ca rtridge is correctly oriented.
Front panel recommends reseating or replacing a
printhead
1. Remove the printhead and verify that 
its protective film has been removed.
2 . Clean the electrical connections between the printhead and the carriage. See 
Clean the electrical
connections on a printhead on page 67.
3 . Reinsert the printhead into the carriage and check the front panel message.
4 . If the problem persists, 
insert a new printhead.
Clean the printheads
Periodic printhead cleaning is performed automatically, as long as the  printer is kept turned on. However,
you should clean the printheads if you are experiencing poor image quality and cannot resolve the issues
by other methods. This ensures that there is fresh in k in the nozzles and helps to prevents nozzle clogs.
If you have printed the Printhead  status plot, you know which colors are failing. Clean the pair of
printheads that are not performing adequately. If you are not sure which printheads to clean, clean all of
the printheads.
To clean the printheads, go to the  printers front panel and select the 
 icon, select Image quality
maintenance  > Clean printheads , and then select which printhe ads you want to clean. You can
clean all of the printheads or only some of them. Your choices are:
● Clean all
● Clean M-Y
