							8.Plug in and switch on the printer.
9.Power the printer on at the front panel.
Align the printheads
Precise alignment between printheads is essential for accurate colors, smooth color transitions, and
sharp edges in graphical elements. Your printer has an automatic printhead alignment process which
runs whenever a printhead has been accessed or replaced.
In cases where the paper has jammed or you are experiencing problems with color accuracy, see 
Color
management on page 67; you may need to align the printheads.
NOTE:If the paper has jammed, it is recommended that you reinsert the printheads and initiate the
realignment procedure with the Image Quality Maintenance menu 
.
CAUTION:Do not use transparent or semi-transparent paper to align the printheads.
Reinsert printheads procedure
1.If the realignment process is running and the wrong paper is loaded, press the Cancel key on the
front panel.
CAUTION:Do not print if the realignment process has been canceled. You can restart the
alignment with the Image Quality Maintenance menu procedure.
2.Load the paper you wish to use, see Paper handling on page 33. You can use a roll or cut sheet,
however, it must be A3 landscape or larger.
CAUTION:Do not use transparent or semi-transparent paper to align the printheads.
3.Remove and re-insert all the printheads, see Remove a printhead on page 118 and Insert a
printhead on page 121. This starts the printhead alignment procedure.

							4.Ensure the window is closed, as a strong light source near the printer during printhead realignment
can affect alignment.
5.The process takes about six minutes. Wait until the front-panel display shows the process complete
before using the printer.
NOTE:The printer prints a calibration image. Do not worry about the image. The front-panel
display shows any errors in the process.
Image Quality Maintenance menu procedure
1.Load the paper you wish to use, see Paper handling on page 33. You can use a roll or cut sheet,
however, it must be A3 landscape or larger (420 by 297 mm).
CAUTION:Do not use transparent or semi-transparent paper to align the printheads.
2.Press the Menu key to return to the main menu and select the Image Quality Maintenance menu
icon 
, then Align printheads. The printer checks to see if it has enough paper to run the
realignment.
3.If the loaded paper is satisfactory, the printer runs the realignment and prints a realignment pattern.
Ensure the window is closed, as a strong light source near the printer during printhead realignment
can affect alignment.
4.The process takes about five minutes. Wait until the front-panel display shows the process
complete before using the printer.
Scanning errors during alignment
If the alignment process fails, a Scanning problems message appears on the front panel. This means
that the alignment has not completed successfully. Therefore the printer is not aligned and the alignment
should be repeated before printing with good image quality. The problem may be due to:
●The paper used was not valid, repeat the alignment with valid paper
●Printhead health problems, clean printheads, see 
Clean the printheads on page 169
●The alignment was done with the window open, repeat the alignment with the window closed
If the problem persists after using valid paper, cleaning the printheads and keeping the window closed,
there may be a failure in the scanning system needing reparation or the printheads, although clean, may
not work and need to be replaced.

							Printhead status messages
These are the possible printhead status messages:
●OK: the printhead is working normally, with no known problems
●Missing: there is no printhead present or it is not correctly installed in the printer.
●Test printhead separately: you are recommended to test the printheads individually to find the
failing printhead. Remove all the printheads and insert them alone one by one, closing the latch
and the carriage cover after every insertion. The front-panel display indicates the failing one
showing the reseat or replace message.
●Reseat: you are recommended to remove the printhead and then reinsert it. If that fails, clean the
electrical connections, see 
The front-panel display recommends reseating or replacing a
printhead on page 169. If that fails, replace the printhead with a new printhead, see Remove a
printhead on page 118 and Insert a printhead on page 121.
●Replace: the printhead is failing. Replace the printhead with a working printhead, see 
Remove a
printhead on page 118 and Insert a printhead on page 121.
●Replacement incomplete: a printhead replacement process has not completed successfully, re-
launch the replacement process and let it finish completely (it is not needed to change the
printheads).
●Remove: the printhead is not a suitable type for use in printing.

General printer issues
 
						

							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:
●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 and unplug
the power cord, wait until the electromagnetic environment has returned to normal, then turn it on
again. If you still experience problems, please contact your customer service representative.
●Nesting may be on and the printer is waiting for the specified nest wait time before calculating the
appropriate nests. In this case, the front panel shows the remaining time needed for nesting.
●You may have the wrong graphic language setting, see 
Change the graphic language setting
on page 32.
●You may not have installed in your computer the correct driver for your printer, see the Assembly
instructions.
●If you are printing on a sheet, you must specify sheet as the paper source in your printer driver.
●The printer may be holding the job for paper or accounting information, see 
Job status
messages on page 106.
●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 on your screen,
and you must click the Print button to start printing.
●If you are using Mac OS with a USB connection, you may find that you need to change the data
encoding. Select the Setup menu icon 
, then Printing preferences > PS  > Select
encoding > ASCII. Then configure your application to send ASCII data.
The printer seems slow
Here are some possible explanations.
●Did you set the print-quality to Best or Max Detail? Best-quality and maximum detail prints take
longer.
●Did you specify the correct paper type when loading the paper? Photo and coated papers require
more drying time between passes. To find out the printers current paper type setting, see 
View
information about the paper on page 50. Some paper types require more time for printing.
●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.
The printer printed on undesirable paper
If the printer prints your job before you were able to load your desired paper, you may have Any selected
for the Paper Type in the printer driver. When Any is selected the printer will print immediately on
176 Chapter 17   Troubleshooting general printer issues ENWW

							whichever paper is loaded. Load your desired paper, see Paper handling on page 33, and select your
paper type specifically in the driver.
●In the Windows driver dialog: select the Paper/Quality tab, then select your paper type in the
Paper Type drop-down list.
●In the Mac OS Print dialog (T1120): select the Paper Type/Quality panel, then select your paper
type in printer in the Paper Type drop-down list.
●In the Mac OS PS Print dialog (T1120ps): select the Image Quality panel, then select your paper
type in the Paper Type drop-down list.
NOTE:Any is the driver default.
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.
●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 application, see 
Printing on page 55.
●Ensure that the printer works correctly when printing from other applications.
●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 USB cable.
●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.
●Ensure that the graphic language setting is correct, see 
Change the graphic language setting
on page 32.
●If the printer is connected with a USB, try to disconnect and reconnect the USB cable with the
computer.

Automatic file system check
When you turn on the printer, you will occasionally see a front panel display similar to the one shown
below.
A file system check is taking place; it can take up to 40 minutes. Please wait until it finishes.
CAUTION:If you turn the printer off before the file system check has finished, the file system could
be seriously damaged, making the printers hard disk unusable. In any case, the file system check will
restart from the beginning whenever you turn the printer on again.
178 Chapter 17   Troubleshooting general printer issues ENWW
General printer issues
 
						

							A file system check is scheduled every 90 days, in order to maintain the hard disks file system integrity.
NOTE:When the printer is powered back on, it takes about three minutes to initialize and check and
prepare the printheads. However, it can take up to 40 under some conditions, for example, when the
printer has not been used for a long period of time and requires more time to prepare the printheads.
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.
No output when printing from Microsoft Visio 2003
For more information about problems when printing large images (more than 129 inches long) from
Microsoft Visio 2003, see Microsofts online knowledge base: 
http://support.microsoft.com/search/.
To avoid these problems, it is possible to scale the image down in Visio to a size shorter than 129 inches
and then to scale the drawing up in the driver by using the Scale to options in the Effects tab of the
Windows driver. If the down-scaling in the application and the up-scaling in the driver match, the result
is as originally intended.
Unavailable driver features when printing from
QuarkXpress 
When you print from QuarkXPress, the following driver features are not available.
●Print Preview
●Rotation
●Scaling
●Microsoft Office features or paper saving options
●Back to front printing
If you are using the HP-GL/2 driver, the following features are not available.
●Print Preview
●Back to front printing
To get the same results, use the equivalent features available in QuarkXPress.

General printer issues
 
						

							Printer alerts
Your printer can communicate two types of alerts:
●Errors: Mainly alerting you to the fact that the printer is unable to print. However, in the driver,
errors can also alert you to conditions that could ruin the print, such as clipping, even if the printer
is able to print.
●Warnings: Alert you when the printer needs attention either for an adjustment, such a calibration
or for a possible unprintable situation, such a preventive maintenance or low ink.
There are four different alerts communicators within your printers system.
●Front-panel display: The front panel only shows the most relevant alert at a time. It generally
requires the user to press the OK key for confirmation, but in the case of a warning, it disappears
after a timeout. There are permanent alerts, such as ink cartridge low on ink, that reappear when
the printer becomes idle and there is not another more severe alert.
TIP:From the front panel display you can configure paper mismatch alerts, see Handle paper
conflicts on page 22.
●Embedded Web Server: The upper-right corner of the EWS screen shows the Printer status. If
there is an alert in the printer, the status shows the alert text.
●Driver: The driver shows alerts. The driver warns about job configuration settings that may produce
a problem in the final output. If the printer is not ready to print, it displays a warning.
●HP Printer Utility: To see alerts, go to the Overview tab and review the Items needing
attention list on the right-hand side.
By default, alerts are only displayed when you are printing and there are printing problems, for
example: cartridge low or out of ink or printer out of paper. If alerts are enabled and there is a
problem that prevents printing, you see a pop-up window, which explains why the printer is not
going to print. Follow the instructions to achieve your required result.
NOTE:There are environments that do not support bidirectional communication, for example: a
shared Mac OS computer or a Windows computer connected to the printer with USB. In those
cases, alerts do not reach the job owner.
