							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 are recommended to switch to Normal mode or use a paper
roll with a 3 inch core.
The trailing edge of the paper curling up
Use the Optimize for images setting: see Change the print quality.
The paper is not completely ejected
Check for any obstruction in the paper path, such as loose objects or other pieces of paper.

							The diagnostics light is flashing
The most likely explanation is that the scanning area needs cleaning. Perform the routine
maintenance procedures explained in your online guide, which include cleaning. Restart the scanner
when you have finished the maintenance procedures.
If the light continues to flash, there may be camera position errors. In this case, contact HP Support.
The wait light is flashing
This indicates that the scanner needs to make some readjustment but is unable to do so. Remove all
paper from the scanner, ensure the insertion slot height is set to minimum, and wait for the light to
turn off.
The wait and diagnostics lights are both flashing
In this case, disregard the wait light and respond only to the diagnostics light. See The diagnostics
light is flashing.

							The scanner displays a warning message
The scanner may recommend performing maintenance in some circumstances:
●Scanner Maintenance has not been run for 30 days.
●Lamp quality fails. The filter should be replaced at the same time.
●Glass plate quality fails.
●Original background quality fails.
If you see any of these warnings displayed, consult the scanners online guide for information on
recommended maintenance procedures.
The scanner software is in the wrong language
If your scanner software is in the wrong language for any reason, you can easily change the
language as follows:
1.In the Setup tab, press the Options button.
2.Press the System button.
3.Press the Advanced button and give the administrator’s password.
4.Press the Change Language button.
5.Select your preferred language.
You will now have to wait a short time while the system shuts down and restarts.
The scanner software does not start
If your scanner system software does not start up when you turn on the touch screen, trying turning it
off and then on again.
If it persistently fails to start up, you may need to reinstall the software, using the ’System Recovery’
DVD that came with your scanner system.
1.With the system on, insert the System Recovery DVD in the DVD drive.
2.Power off the touch screen and then power it on again.
3.Follow the instructions on the screen.
4.When the software has been reinstalled, you will be prompted to remove the DVD and restart
the touch screen.
5.When the touch screen restarts, it will ask you to calibrate the position of the pointer. Please do
so by touching the targets that will appear three times. To obtain a good and consistent
calibration, you should be standing in your normal position and using whatever pointer you
normally use to operate the touch screen (your finger, or some other object).
6.After touching the three targets, you will be asked to touch any part of the touch screen. If you
are happy with the result of the calibration, press the Yes button. If you are prompted to restart
the system, press No.

							7.The language selection screen should appear. Select the language you want to use for the
Designjet Scan application. The touch screen will automatically restart in the selected language.
8.Allow time for the operating system to be reloaded. The process has finished when the touch
screen shows the Copy tab of the Designjet Scan application.
The CD or DVD cannot be read by my computer
The scanner creates CDs and DVDs compliant with the ISO 9660 standard plus Joliet Extension.
This standard is commonly supported but it cannot be guaranteed that all computers will support it.
A media profile cannot be generated
Check that the scanner and the printer are both switched on and ready for normal operation.
The printer puts the job on hold
This can happen if your scanner account has not been properly set up (see Enable or disable
scanner accounts), or if the printer does not have the correct paper type or size loaded.
The printer loads the wrong roll
The HP Designjet 4500 Printer series may automatically load the other roll in some circumstances in
order to save paper. To prevent this behavior, select the 
 icon on the printers front panel, then
Paper handling options > Roll switching options > Minimize roll changes.
The margins are too wide
When you set the margins in the scanner software and then print an image, the printer adds its own
default margins to the margins you have defined.
You can tell the scanner to compensate for this behaviour by selecting the Setup tab, then the
Margins button, then the Clip contents by printers margins option. Subsequently, the margins you
select in the scanner software should correspond to the printed margins. However, if image is as
wide as the paper, you may find that the edges of the image are not printed.
Streaks in the scanned image
If the problem is visible when previewing the image on screen, it may be due to dirt or scratches on
the glass. First try to clean the glass (see 
Clean the glass). If the problem persists, you may need to
replace the glass.

							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.
The following table provides suggested actions to recover from these error conditions:
CodeShort messageSuggested action
