HP Designjet 4520ps 42 in User Manual

							●If you are using Mac OS with a USB connection, you may find that you need to change the data
encoding. Select the 
 icon, then Default printing options > PS options > Select encoding
> ASCII. Then configure your application to send ASCII data.
●The print file may lack a proper file terminator and the printer is therefore waiting for the specified
I/O timeout period before assuming it is complete.
●Nesting may be on and the printer is waiting for the specified nest wait timeout period before
calculating the appropriate nests. In this case, the printer display shows the remaining time for the
nesting timeout.
●You may have requested a print preview from your printer driver. This is a function you can use to
check that the image is the one you want. In this case, the preview is displayed in a Web browser
window, and you must click a button to start printing.
The printer seems slow
Here are some possible explanations.
●Did you set the print quality to Best? Best-quality prints take longer.
●Did you specify the correct paper type when loading the paper? To find out the printers current
paper type setting, see 
View information about the paper on page 40.
●Do you have a network connection to your printer? Check that all components used in the network
(network interface cards, hubs, routers, switches, cables) are capable of high-speed operation. Is
there a lot of traffic from other devices on the network?
●Did you specify Extended drying time in the front panel? Try changing the drying time to Optimal;
see 
Drying time on page 201.
●Are your printheads in good condition? The printer may print slower to maintain print quality when
a printhead is faulty. Check the printhead status in the front panel or in the Embedded Web Server,
and recover or replace printheads if necessary.
●Do you have high-density black areas in your image? In this case, the printer may change
temporarily to a slower print quality option in order to maintain quality.
The application slows down or hangs up while generating
the print job
Large quantities of data may be necessary to generate a high-quality large-format print job. In some
cases, this may cause your application to slow down very noticeably (taking several minutes to generate
the print job) or even to hang up.
To avoid this behavior in the Windows HP-GL/2 and HP RTL driver, select the Services tab, then the
Troubleshoot Software Problems icon, then try turning on the Compatibility with 16-bit applications
option. However, we recommend turning off this option for most jobs, because it may adversely affect
final print quality.
Communication failures between computer and printer
Some symptoms are:
●The front-panel display does not show the “Receiving” message when you have sent an image to
the printer.
●Your computer displays an error message when you are trying to print.
ENWWThe printer seems slow 181
Other problems
 
						

							●Your computer or printer “hangs” (stays idle) while communication is taking place.
●Your printed output shows random or inexplicable errors (misplaced lines, partial graphics etc.)
To solve a communication problem:
●Ensure that you have selected the correct printer in your software.
●Ensure that the printer works correctly when printing from other software.
●Remember that very large prints may take some time to receive, process and print.
●If the printer is connected to a network, try using it when connected directly to your computer
through a FireWire or USB cable. See 
Connect the printer on page 191.
●If your printer is connected to your computer through any other intermediate devices, such as switch
boxes, buffer boxes, cable adapters, cable converters, etc., try using it when connected directly to
your computer.
●Try another interface cable. See 
Connect the printer on page 191.
●Ensure that the graphic language setting is correct. See 
Change the graphic language setting
on page 65.
I cannot access the Embedded Web Server from my
browser
If you have not done so already, please read Access the Embedded Web Server on page 17.
●Have you set an administrator password for the Embedded Web Server on the Security page, and
then forgotten the password? If so, select the 
 icon, then Printer configuration > Resets >
Reset EWS password.
●At the printers front panel, select the 
 icon, then Printer configuration > Allow EWS > On.
●Check that you have a TCP/IP (network or FireWire) connection to your printer. If you connect
directly to your printer with a USB cable, you cannot use the Embedded Web Server.
●If you are using a FireWire connection, make sure that your computers operating system supports
IP over IEEE-1394 (FireWire). For example, Windows XP and Windows 2003 Server support IP
over FireWire, but Windows 2000 does not. Make sure that your operating system is configured to
use IP over FireWire.
●At the printers front panel, check that IP is enabled for the type of connection you are using. Select
the 
 icon, then I/O setup, then the type of connection you are using, then View information,
and check that you see IP enabled. If not, you may need to use a different type of connection.
●If you normally access the Web through a proxy server, try bypassing the proxy server and
accessing the Web server directly. You can do this by modifying your browser settings.
For instance, if you are using Internet Explorer 6 for Windows, go to Tools > Internet Options
> Connections > LAN Settings and check the Bypass proxy server for local addresses box.
Alternatively, for more precise control, click the Advanced button and add the printers IP address
to the list of Exceptions for which the proxy server is not used.
●Try switching off the printer (with the Power key on the front panel) and then switching it on again.

							An out-of-memory error
There is no direct relationship between the size of a file in your computer and the amount of memory
needed in the printer to print the file. In fact, because of file compression and other complicating factors
it is often impossible to estimate how much memory will be needed. So it is possible that a print will fail
for lack of memory even though you may have successfully printed larger files in the past. In this case
you may need to consider adding more memory to your printer.
If you are using the Windows HP-GL/2 and HP RTL driver, you can often solve printer memory problems
by selecting the Services tab, then the Troubleshoot Software Problems icon, then turning on the Send
Job as a Bitmap option.
NOTE:If you select this option, the time needed to process the job in your computer may be
considerably longer.
An AutoCAD 2000 memory allocation error
After installing the printer driver, when you try to print for the first time from AutoCAD 2000, you may
see a message saying Memory allocation error, after which your image is not printed.
This is due to a problem in AutoCAD 2000, and it can be fixed by downloading the Plotting Update Patch
(plotupdate.exe) from the Autodesk Web site, 
http://www.autodesk.com/.
This patch is also worth trying if you have any other strange problems when printing from AutoCAD
2000.
The platen rollers squeak
It may occasionally be necessary to oil the rollers. The Maintenance Kit, which came with your printer,
contains a bottle of suitable oil.
1.Turn off the printer using the Power key on the front panel.
2.Open the window.

							3.There are small holes in the platen beside some of the rollers.
Using the bottle of oil supplied with the Maintenance Kit, insert the pointed end of the bottle into
each hole in turn, and put three drops of oil into each hole.
4.Repeat the process until all of the holes in the platen have had three drops of oil placed in them.
5.Be careful not to spill oil onto the platen.
6.If there is oil on the platen, wipe it away with the cloth supplied with the kit.

							Color emulation modes
Your printer can emulate the color behavior of other devices: RGB devices such as monitors, and CMYK
devices such as presses and printers. See 
Select the color emulation mode on page 69.
If you have problems making your printer emulate another HP Designjet printer, see
Color matching
between different HP Designjets on page 157.
For a good emulation, the printer needs a specification of the colors these devices can reproduce. The
standard way of encapsulating such information is in ICC profiles. As part of the solution, we provide
the most common standards for the different devices. Apart from selecting the appropriate ICC profile,
you should select the appropriate rendering intent depending on the type of print: business presentation,
photography or proof. See 
Set the rendering intent on page 69. For reference information on the broader
aspects of color printing refer to: 
http://www.hp.com/hpinfo/community/environment/productinfo/
psis_inkjet.htm
The options are as follows.
NOTE:PDF and PostScript files can be used with PostScript printers only.
CMYK color emulation
All CMYK emulation options apply to PDF, PostScript, TIFF and JPEG files only.
●None (Native): no emulation, for use when the color conversion is done by the application or
operating system, and therefore the data arrive at the printer already color–managed.
●HP CMYK Plus: a set of HP proprietary re-rendering rules that will produce a good result for most
digital commercial printing jobs, by expanding the reduced gamut of your press into the wider gamut
of your printer.
●U.S. Sheetfed Coated 2 uses specifications designed to produce quality separations using U.S.
inks under the following printing conditions: 350% total area of ink coverage, negative plate, bright
white offset stock
●U.S. Sheetfed Uncoated 2 uses specifications designed to produce quality separations using U.S.
inks under the following printing conditions: 260% total area of ink coverage, negative plate,
