							The front panel displays that the stacker is disconnected
If the front panel constantly or intermittently claims that the stacker is disconnected from the printer,
there may be a problem with the height of the stacker. Use the following procedure to adjust the height
of the stacker.
1.Using an hexagonal wrench, loosen the upper hexagonal nut on both of the stackers wheels that
are closest to the printer.
2.Adjust the height of the stacker by rotating the lower hexagonal nut clockwise or anti-clockwise.

							The printers start-up process does not complete
If the printers start-up process stops when the front panel is displaying the number 17, this indicates
that there is a problem with the file system on the printers hard disk, so the printer is checking the whole
file system and making any necessary corrections. This problem can arise when there has been a power
cut while the printer was switched on, or if there is a physical problem with the hard disk.
Checking the whole file system normally takes about half an hour. There is nothing you can do to speed
it up. If you turn off the printer, the file system check will restart whenever you turn it on again.
If you experience this problem repeatedly when there has been no power cut, contact your customer
service representative.
A front panel message 
The front panel displays messages of many kinds; some allow you to continue using the printer while
others require you to take action before you can continue.
●If the printer detects a condition of which you should be aware, it displays a message for your
information. Examples of information messages are performance limiting conditions and printer
maintenance requirements. Once you have read the message you can remove it by pressing
the Select key and continue to use the printer.
●If the printer detects an error, an error code and short message are displayed on the front panel.

A “printhead monitoring” message
This is not an error message. The message is displayed whenever the Printhead monitoring option is
set to Intensive. If you change the setting to Optimized, the message will not appear. See 
Manage
printhead monitoring on page 97.
A “printheads are limiting performance” message
This message appears on the front panel during printing when the printer has detected that one or more
printheads are not performing optimally, and so it needs to make extra passes to maintain print quality.
To eliminate this message, choose one of the following:
●Select a higher print quality; see 
Change the print quality on page 57.
●Clean the printheads; see 
Recover (clean) the printheads on page 97.

An “on hold for paper” message [4520]
NOTE:This topic applies to the HP Designjet 4520 Printer series only.

							NOTE:To see the job queue at the front panel, select the  icon and then Job queue.
Based on a set of criteria that you can set when sending a job, the HP Designjet 4520 will decide which
of the rolls of paper loaded in the printer is more suitable to print the job. If there is no roll of paper
available that meets all the conditions set previously, the HP Designjet 4520 will then put the job on hold
for paper. You can manually resume the job and forces it to print on a paper different from the one that
was set when the job was sent, otherwise it will stay on hold.
Which criteria are used to decide to which roll a job will be printed?
When a user sends a job, the paper type that is desired can be set (in the driver or in the Embedded
Web Server). The printer will print this job on a roll of paper of the chosen paper type and one that is
wide enough to print the drawing without clipping. In case there is more than one roll where the job could
be printed meeting all the criteria, the roll will be chosen according to your preferences. These can be
set by using a setting in the printer’s Front Panel: Paper Menu > Paper handling options > Roll
switching options which has two possible values:
●Minimize paper waste. If this option is chosen, the printer will choose the narrowest roll that meets
all the criteria, to avoid wasting paper due to trimming.
●Minimize roll change. If this option is chosen, the printer will choose the roll that is currently loaded
on the print platen, to avoid wasting time with a roll switch.
The default option is Minimize paper.
When is a job put on hold for paper?
A job is put on hold for paper in the following cases:
●The paper type that has been selected by the user is not currently loaded on the printer.
●The paper type that has been selected by the user is loaded on the printer, but the drawing is too
wide to fit on any of the rolls of this paper type without clipping.
If I load a new roll of paper, will jobs that were on hold for paper be
automatically printed?
Yes. Since firmware 8.1.1.3, every time a new roll of paper is loaded, the printer will check if there are
any jobs on hold for paper that could be printed on the loaded roll. In case the answer is yes, the printer
will ask if these jobs should be automatically resumed with the following message:
●Would you like to print the jobs that are on hold for paper? Yes/No
I don’t like jobs being put on hold for paper. Can I prevent it?
Yes, this can be done from the front panel: select the  icon and then Job management options >
Enable on hold for paper. There are two options:
●When needed (default value). Jobs are put on hold for paper when there is no paper loaded on
the printer that meets the necessary conditions: correct paper type and correct paper size.
●Never. Jobs are never put on hold for paper. If there is no paper loaded that meets all the conditions
set by the user, the job is printed on whichever roll seems most suitable for it.
I set the option “Enable on hold for paper” to Never, but some jobs are still
put on hold
If the Show print preview option is selected in the driver or the Embedded Web Server, jobs are put
on hold until you have checked the preview and resumed the job. Check that the Show print preview

							option is not checked in the driver, and that there are no pending preview windows waiting for
confirmation to continue printing.
My job is exactly as wide as the roll of paper that is loaded on the printer,
but is put on hold for paper
Margins are managed in different ways depending on the file type:
●For HP-GL/2 and HP RTL files, by default, margins are included inside the drawing, so a 36 inches
HP-GL/2 and HP RTL file can be printed with margins in a 36 inches roll of paper and will not be
put on hold for paper.
●For other file formats however, like PostScript, PDF, TIFF or JPEG, by default, the printer considers
that margins need to be added outside of the drawing (as in many cases, these formats are used
for photographs and other contents where margins are not included). This means that to print a 36
inches TIFF, the printer needs to add some margins and the drawing needs 36.4 inches of paper
to be printed; this would cause the job to be put on hold if the paper that is loaded on the printer is
only 36 inches wide.
For these file formats, if it is desired to print them without adding extra margins outside of the
drawing, the Clip contents by margins option can be used. This option will force the margins to be
set inside of the drawing, so a 36 inches TIFF can be printed in a 36 inches roll of paper without
being put on hold. However, it needs to be taken into account that, if there is no white space already
included in the drawing’s borders, some contents could be clipped because of the margins.
The printer does not print
If all is in order (paper loaded, all ink components installed and no file errors), there are still reasons
why a file you have sent from your computer may not start printing when expected, this is because the
file has been put on hold for paper:
●You may have an electrical power problem. If there is no activity at all from the printer, and the front
panel does not respond, check that the power cable is connected correctly and that there is power
available at the socket.
●You may be experiencing unusual electromagnetic phenomena, such as strong electromagnetic
fields or severe electrical disturbances, which can cause the printer to behave strangely, or even
stop working. In this case, turn off the printer using the Power key on the front panel, wait until the
electromagnetic environment has returned to normal and then turn it on again. If you still experience
problems, please contact your customer service representative.
●You may have the wrong graphic language setting. See 
Change the graphic language setting
on page 65.
●You may not have installed in your computer the correct driver for your printer. See the Setup
instructions.
●The right paper may not be available to print the job, perhaps because:
◦The selected roll is not loaded.
◦The selected paper type is not loaded on any roll.
◦There is not enough paper of the selected type to print the whole job.
On the HP Designjet 4520 series, a job may be held in the queue for one of these reasons, while
other jobs in the queue are printed because the right paper is available for them. In this case, you
can print the held job by loading the correct paper and using the front panel or the Embedded Web
Server to continue the job.
