HP Designjet Z5200ps User Manual

							There is another possible explanation for a clipped image. Some applications, 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.
NOTE:An image 32,768 pixels long would print at a length of 1.39 m (54.61 in) if you select Best or
Quality in the driver, 2.78 m (109.23 in) if you select Fast, Normal or Speed in the driver.
If you try to print an image larger than this from these applications, the bottom of the image may be
clipped. To print the whole image, try these suggestions:
●Try using the PostScript printer driver to print your job, if you have not already tried it.
●The Windows PCL3 driver dialog includes an option called Max. application resolution, which
enables you to print successfully in this situation. You will not normally need to change the
default setting, which is Auto. However, you can find the option in the Advanced tab, under
Document Options > Printer Features.
●Save the file in another format, such as TIFF or EPS, and open it with another application.
●Use a RIP to print the file.
Some objects are missing from the printed image
Large quantities of data may be necessary to print a high-quality large-format print job, and in some
specific workflows there may be issues that can lead to some objects missing from the output. Here
are some suggestions to help you to avoid this problem.
●Try using the PostScript printer driver to print your job, if you have not already tried it.
●Select a smaller page size and scale to the desired final page size in the driver or in the front
panel.
●Save the file in another format, such as TIFF or EPS, and open it with another application.
●Use a RIP to print the file.
●Reduce the resolution of bitmap images in your application software.
●Select a lower print quality in order to reduce the resolution of the printed image.
●In the Advanced tab of the PCL3 driver dialog for Windows, select Document options, Printer
features, then set Max. application resolution to 300.
NOTE:The above settings are mentioned for troubleshooting purposes and may adversely
affect the final output quality or the time necessary to generate the print job. Therefore, they
should be restored to their default values if they do not help to solve the problem.

1.Check that the paper type you have loaded corresponds to the paper type selected in the front
panel and in your software. To check on the front panel, use the View loaded paper key.
2.Check that you are using appropriate print-quality settings for your purposes (see 
Printing
on page 43). Select the custom print-quality options in the driver dialog (Mac OS Print dialog),
and try turning on the Maximum detail option. You may wish to reprint your job at this point in
case the problem has been solved.
3.If lines are too thin or missing, print the Image Diagnostics Print. See 
The Image Diagnostics
Print on page 155.
4.Try aligning the printheads. See 
Align the printheads on page 164. After alignment, you may
wish to reprint your job in case the problem has been solved.
5.Go to the front panel and press the View loaded paper key to see the paper advance calibration
status. If the status is RECOMMENDED, you should perform paper advance calibration: see
Recalibrate the paper advance on page 139.
If the problem persists despite all the above actions, contact your customer service representative for
further support.
Lines appear stepped or jagged
If lines in your image appear stepped or jagged when printed:
1.The problem may be inherent in the image. Try to improve the image with the application you
are using to edit it.
2.Check that you are using appropriate print-quality settings. See 
Printing on page 43.
3.Select the custom print-quality options in the driver dialog (Mac OS Print dialog), and turn on the
Maximum detail option.
4.If you are using the PCL3 driver for Windows, you can change your image rendering resolution
to 300 ppi or 600 ppi depending on your printing needs. You can find the Max. application
resolution option in the driver dialogs Advanced tab, under Document Options > Printer
Features.

							Lines print double or in the wrong colors
This problem can have various visible symptoms:
●Colored lines are printed double, in different colors.
●The borders of colored blocks are wrongly colored.
To correct this kind of problem:
1.Reseat the printheads by removing them and then reinserting them. See 
Remove a printhead
on page 110 and Insert a printhead on page 112.
2.Align the printheads. See

Lines are blurred
Humidity can cause ink to soak into the paper, making the lines blurred and fuzzy. Try the following:
1.Check that your environmental conditions (temperature, humidity) are suitable for high-quality
printing. See 
Environmental specifications on page 182.
2.Check that the paper type you have loaded corresponds to the paper type selected in the front
panel and in your software. To check on the front panel, use the View loaded paper key.
3.Try changing to a heavier paper type, such as HP Heavyweight Coated Paper, HP Super
Heavyweight Plus Matte Paper or Digital Fine Art paper.
4.Select a paper type that is slightly thinner than the paper you have loaded; this will persuade the
printer to use less ink. Here are some example paper types in ascending order of thickness:
Plain Paper, Coated Paper, Heavyweight Coated Paper, Fine Art Paper, Super Heavyweight
Plus Matte Paper, Thick Fine Art Paper (>250 g/m²).
5.If you are using glossy paper, try changing to a different type of glossy paper.
6.Select the custom print-quality options in the driver dialog (Mac OS Print dialog), and turn on the
More passes option.

							The Image Diagnostics Print
The Image Diagnostics Print consists of patterns designed to highlight printhead reliability problems.
It helps you to check the performance of the printheads that are currently installed in your printer, and
whether any printhead suffers from clogging or other problems.
To print the Image Diagnostics Print:
1.Use the same paper type that you were using when you detected a problem.
2.Use the View loaded paper key on the front panel to check that the selected paper type is the
same as the paper type loaded into the printer.
3.
At the printers front panel, select the Image Quality Maintenance menu icon 
, then Print
diagnostic image.
It takes about two minutes to print the Image Diagnostics Print.
The print is divided into two parts, both of which test printhead performance.
●Part 1 (top) consists of rectangles of pure colors, one for each printhead. This part represents
the print quality that you will get from each color.
●Part 2 (bottom) consists of small dashes, one for each nozzle on each printhead. This part
complements the first, and aims more specifically to detect how many faulty nozzles each
printhead has.
Please look carefully at the print. The names of the colors are shown above the rectangles and in the
center of the patterns of dashes.
First look at the upper part of the print (part 1). Each colored rectangle should be a uniform color
without any horizontal lines across it.
Then look at the bottom part of the print (part 2). For each individual colored pattern, check that most
of the dashes are present.
ENWWThe Image Diagnostics Print 155
Print-quality issues
 
						

							If you see horizontal lines in part 1 and also missing dashes in part 2 for the same color, the printhead
responsible needs cleaning. However, if the rectangles look solid, do not worry about just a few
missing dashes in part 2; these are acceptable because the printer can compensate for a few clogged
nozzles.
Here is an example of a light gray printhead in a good state:
And here is an example of the same printhead in a bad state:
Corrective action
1.Clean any faulty printheads (see Clean the printheads on page 160). Then reprint the Image
Diagnostics Print to see whether the problem has been solved.
2.If the problem remains, clean the printheads again, and reprint the Image Diagnostics Print to
see whether the problem has been solved.
3.If the problem remains, consider cleaning your printheads manually (see 
Clean the printheads
on page 160). You could also try reprinting your current print job, in case it now prints
satisfactorily.
156 Chapter 13   Troubleshooting print-quality issues ENWW
Print-quality issues
 
						

							4.If the problem remains, try cleaning the printhead drop detector. The printer normally notifies you
when this is necessary, but it may be worth trying even if the printer has not suggested it. See
Clean the printhead drop detector on page 161.
5.If the problem still remains, replace any persistently faulty printheads (see 
Handling ink
cartridges and printheads on page 105), or contact HP Support (see Contact HP Support
on page 177).
If you still have a problem
If you still experience print-quality problems after applying the advice in this chapter, here are some
further things that you can do:
●Try using a higher print-quality option. See 
Printing on page 43.
●Check the driver you are using to print with. If it is a non-HP driver, consult the driver vendor
about the problem. You could also try using the correct HP driver, if feasible. The latest HP
drivers can be downloaded from 
http://www.hp.com/go/Z5200ps/drivers/.
●If you are using a non-HP RIP, its settings may be incorrect. See the documentation that came
with the RIP.
●Check that your printers firmware is up to date. See 
Update the firmware on page 121.
●Check that you have the right settings in your software application.

							The front-panel display recommends reseating or
replacing a printhead
1.From the front panel, turn the power off then on.
2.Check the front-panel display message, if it shows the ready message, the printer is ready to
print. If the problem remains, continue with the next step.
3.Remove the printhead, see 
Remove a printhead on page 110.
4.Clean the electrical connections on the backside of the printhead with a lint-free cloth. You can
carefully use de-ionized or distilled water if moisture is needed to remove residue. Do not use
water.
CAUTION:This is a delicate process and may damage the printhead. Do not touch the
nozzles on the bottom side of the printhead, especially not with any alcohol.
5.Reinsert the printhead, see Insert a printhead on page 112.
6.Check the front-panel display message. If the problem remains, try a new printhead.
Clean the printheads
As long as the printer is kept turned on, an automatic cleaning is performed periodically. This ensures
there is fresh ink in the nozzles and prevents nozzle clogs, which ensures color accuracy. If you have
not already done so, please see 
The Image Diagnostics Print on page 155 before proceeding.
To clean the printheads, go to the front panel and select the Image Quality Maintenance menu icon
, then Clean printheads. If you have gone through the Image Quality Diagnostic print process,
you know which colors are failing. Select the pair of printheads which contain the failing colors. If you
are not sure which colors to clean, you can also select to clean all printheads. Cleaning all printheads
takes about 10 minutes. Cleaning a single pair of printheads takes about six minutes.
NOTE:Cleaning all printheads uses more ink than cleaning a single pair.
If you have cleaned the printheads using the Clean printheads procedure from the front panel and
are still experiencing print-quality problems, you can try cleaning the printhead nozzles manually
using the following procedure.
CAUTION:This is a delicate process and may damage the printhead. Do not touch the electrical
connections on the backside of the printhead.
