							Prints do not stack correctly in the bin
●Paper often tends to curl
 near the end of a roll, which can  cause stacking problems. Load a new
roll, or remove prints manu ally 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 differe nt sizes of paper in the bin.

							Paper scrolling
When printing in Fast mode with highly curled paper, the paper may scroll when ejected to the stacker
tray. To avoid this problem, you ar e recommended to switch to Normal  mode or use a paper roll with a
76.2-mm (3-in) core.
The trailing edge of the paper curling up
Use the  Optimize for images  setting: see Select print quality on page 79.
The paper is not completely ejected
Check for any obstruction in the paper path, such  as loose objects or other pieces of paper.

Troubleshoot stacker
 
						

							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 heig ht 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.
3.When the correct height has been achi
eved, tighten the upper hexagonal nut.

							The printer is not printing
Possible reasons why a file you have sent from your computer is not printing when expected, include
the following:
● A problem with the electrical powe
r might exist. If the printer is not performing and the front panel
does not respond, check that the  power cable is correctly connected  and that the electrical socket
is functioning.
● An unusual electromagnetic phenom
ena may exist, such as strong electromagnetic fields or severe
electrical disturbances. Such occurrences can cause the printer to behave strangely, or even stop
working. Turn off the printer by using the  Power button on the front panel, wait until the
electromagnetic environment has returned to normal , and then turn the printer on again. If the
problems persist, contact your  customer service representative.
● The graphic language setting might be incorrectly set.
● The correct printer driver might not have been installed in your computer.
● One of the following paper scenarios might exist:
◦
The paper name that appears on the front panel does not reflect the p
aper that is loaded in
the printer.
◦ There is not a sufficient amount of paper 
on the loaded roll to print the entire job.
Under these conditions, one print job might be printe d, while another print job is held in the print
queue. To resolve this issue, unload the roll from the printer and load a new roll, using the front
panel to guide you  through the process.
● The nesting setting might be  On and the printer is waiting for the nest timeout to expire. Under this
condition, the front panel shows the remaining time.
● You might have requested a print preview in your printer driver. Under this
 condition, the preview
appears in a Web browser.
A job has not been printed
These are some possible reasons why a particular job may not be printed.
● The job specifies a paper type that is not loaded.
● The job specifies a paper source that has no paper loaded.
● The job is wider than the loaded paper.
● The stacker is installed, and the load
ed paper is not compatible with it.
● The job specifies no paper type nor pape
r source, and the roll is protected.
The software application slows down or stalls while
generating the print job
Large quantities of data might be necessary to generate a high-quality  large-format print job. This can
cause your software program to slow down significan tly or stall. Lowering the print resolution may help
to avoid this scenario, however, lowering  the print resolution reduces image quality.

							In the Windows HP-GL/2 driver, click the Advanced tab, select Document options  > Printer
features , and then set  Max. Application resolution  to 300.
The printer seems slow
Here are some possible explanations:
●
Did you set the print quality to  Best? Images printed with the  Best print-quality setting require
more time to print.
● Did you specify the correct pape
r type when loading the paper? Check that the paper type that
appears on the front panel matches the  paper that is loaded in the printer.
● Is your printer connected to a network? Check th
at all components used in the network (network
interface cards, hubs, routers, switches, and cables) are capable of high-speed operation. Is there
a lot of traffic from other devices on the network?
● Did you set the drying time to  Extended? Try changing the drying time to  Automatic. See
Change the drying time on page 37.
● Are the printheads in good condition? Printing
 time might increase when a printhead needs
cleaning. Check the printhead status on the fr ont panel or through the Embedded Web Server.
Clean or replace printheads if necessary.
● Do your image contain high-density, black fills? Pri
nting time might increase for images containing
high-density, black fills.
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 shows an error 
message when you try to print.
● Your computer or printer stalls when transferring data.
● Your printed output shows random or inexplicable 
errors (misplaced lines, partial graphics, and so
on).
To solve a communication problem:
● Make sure that you have selected the co
rrect printer in your software program.
● Make sure that the printer wo
rks correctly when printing from other software programs.
● Remember that large images usually require 
more time to receive, process, and print.
● If the printer is connected to your computer by
 a USB cable, try disconnecting and reconnecting
the cable.
● If the printer is connected to your computer thro
ugh any other intermediate devices, such as switch
boxes, buffer boxes, cable adapters, or cable conv erters, remove the intermediate device and try
connecting the printer directly to your computer.

Cannot access the Embedded Web Server
If you have not done so
 already, please read Access the Embedded Web Server on page 21.
NOTE: If you connect your printer dire ctly to your computer with a USB cable, use the HP Utility.
1.
Go to the front panel and select the  icon.
2. Select Connectivity Menu  > Advanced >  Embedded Web Server  > Allow EWS  > On .
3. If you have a TCP/IP connection to your prin ter, go to the front panel and select the 
 icon,
and then select  Connectivity Menu .
4. Select the type of connection you are using.
5. Select View Information .
6. The information should read:  IP enabled: Yes. If it does not, you might need to use a different
connection.
If you still cannot access the Embedded We b Server, turn the printer off with the Power button on the
front panel and then turn it on again.
If you experience very slow progr ess while trying to access the Embedded Web Server, the problem
could be that you are using a  proxy server. Try bypassing the  proxy server and accessing the
Embedded Web Server directly.
● In Internet Explorer 6 for Windows, go to Tools  > Internet Options >  Connections > LAN
Settings , and select the Bypass proxy server for local addresses  check box. You can
also click the Advanced  button to add the printers IP address  to the list of exceptions, for which
the proxy server is not used.
● In Safari for Mac OS, go to  Safari > Preferences  > Advanced  and click the Proxies:
Change Settings button. Add the printers IP address or its domain name to the list of
exceptions, for which the proxy server is not used.
“Out-of-memory” error message
There is no direct relationship between the size of  a file in your computer and the amount of memory
needed to print the file. Because of  file compression and other factors,  it is difficult to estimate how
much memory is needed to print a job. It is possible that the printer will lack  sufficient memory to print a
certain job, despite having printed larger jobs in  the past. Adding memory to your printer is one
solution.
If you are using the Windows HP-GL/2 driver, prin ter memory problems can often be resolved by
clicking the Advanced  tab, selecting Document options, selecting  Printer features, and then
selecting  Print job as raster .
NOTE:If you select this option, the time needed  to process the job in your computer might be
considerably longer.
