● Purge ink
Cleaning all of the printheads take s about 5 minutes. Cleaning any tw o printheads takes about 3 minutes.
Purging the ink takes about 5 minutes.
NOTE: Cleaning all printheads uses more  ink than cleaning a single pair.
NOTE:HP recommends that you purge the ink from th e printheads before printing a job if the
printer has been turned off for more than six week s or if you are experiencing inconsistent colors
from print to print after long storage periods. Purging the ink from the printheads helps to ensure
maximum color consistency; it is  not a remedy for poor printhead health.
Align the printheads
Precise alignment between printheads is essential for  color accuracy, smooth color transitions, and sharp
edges in graphical elements. Your printer has an  automatic printhead alignment process which runs
whenever a printhead has be en accessed or replaced.
In the case of a paper jam, if you have used a cust om paper, or if you are experiencing problems with
color accuracy; you might need  to align the printheads. See 
Align the printheads on page 71.
NOTE: If you experience a paper jam,  HP recommends that you reinsert the printheads and align
the printheads.
TIP: Use the same paper you intend to print on  to align the printheads. Photo paper is
recommended for the best results. Plain; bond; and thin, coated papers are acceptable, but provide
marginal results.
WARNING! Colored papers, glossy canvas, and tran sparent materials such as translucent
bond, clear film, tracing paper, and vellum are no t suitable for aligning the printheads. However,
if you must perform printhead alignment with a mate rial that is not supported, make sure you use
a material with the same thickness as the  material you are going to use for printing.
Reinsert printheads procedure
1. If the printhead alignment process is running
 and the wrong paper is loaded, press the Cancel button
on the front panel.
CAUTION: Do not print if the printhead align ment process has been canceled.
2. Load the paper you want to use. Photo pa
per is recommended for the best results.
WARNING!Colored papers, glossy canvas, and tran sparent materials such as translucent
bond, clear film, tracing paper, and vellum are not suitable for aligning the printheads.
However, if you must perform printhead alignmen t with a material that is not supported, make
sure you use a material with the same thickness as the material you are going to use for
printing.

							3. Remove and reinsert all of the printheads. See Remove a printhead on page 61 and Insert a
printhead on page 64
. This starts the printhead alignment process.
NOTE: Make sure the printer window is  closed during printhead alignment.
4. The process takes about 6 minutes. Wait until th
e front panel shows that the process is complete
before using the printer.
NOTE: A calibration image is printed during th e printhead alignment process. The front
panel shows if there were any errors in the process.
Image Quality Maintenance menu procedure
1 . Load the paper you want to use. Photo paper is re
commended for the best results. Plain; bond; and
thin, coated papers are acceptable, but provide marginal results.
WARNING! Colored papers, glossy canvas, and tran sparent materials such as translucent
bond, clear film, tracing paper, and vellum  are not suitable for aligning the printheads.

							Scan errors during alignment
If the alignment process fails, a Scanning problems message appears on the front panel. This indicates
that the alignment was not completed successfully.  Therefore, the printheads are not aligned and the
alignment should be repeated before printing. Th e problem might be because of one of the following
scenarios:
● The type of paper used in the printhead alignment
 process was not acceptable. Repeat the alignment
process using one of the  recommended paper types.
● The printheads are not clean. Clean the printheads. See 
Clean the printheads on page 168
.
● The printer window was open during the printhead 
alignment process. Repeat the alignment process
with the printer window closed.
If the problem persists after following the recommend ed remedies, try replacing all of the printheads. If
the problem persists after replac ing the printheads, a failure in the scanning system may exist.

							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 power might exist. If the printer is not performing and the front panel
does not respond, verify that the power cable is co
rrectly connected and that the electrical socket is
functioning.
● An unusual electromagnetic phenomena may exist, su
ch 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, cont act 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 do
es not reflect the paper 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 thro ugh 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.
The software program 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 paper 
type when loading the paper? Verify 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  Optimal. See Change
the drying time on page 49.
● Are the printheads in good condition? Printing time
 might increase when a printhead needs cleaning.
Check the printhead status on the front panel or  through the Embedded Web Server. Clean or replace
printheads if necessary.
● Do your image contain high-density, black fills? Pr
inting 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 works 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 yo
ur 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.
● Try another interface cable. See 
Choose which connection method to use on page 13
.
● Make sure that the graphic lang
uage setting is correctly set.
Cannot access the Embedded Web Server
If you have not done so already, please read Access the Embedded Web Server on page 23.

If you still cannot access the Embedded  Web Server, turn the printer off with the  Power button on the front
panel and then turn it on again.
If you experience very slow progress 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 doma in 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 an d other factors, it is difficult to estimate how much
memory is needed to print a job. It is possible that the printer will lack sufficien t 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, printer  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.
AutoCAD 2000 memory allocation error
When printing from AutoCAD 2000 for the firs t time after installing the printer driver, a Memory
allocation error  message might appear.
This is an AutoCAD 2000 problem. Download the Plotting Update Patch ( plotupdate.exe) from the
Autodesk Web site (
http://www.autodesk.com/ ) to resolve the problem.
HP also recommends that you downlo ad the Plotting Update Patch if you experience other problems when
printing from AutoCAD 2000.
