The front-panel menu selections are:
Once you have replaced the printhead, if you have paper loaded, the printer prompts you to start the  Printhead 
alignment
 procedure. If no paper is loaded the printer prompts you to load paper and then automatically starts the 
alignment. The alignment takes several minutes to complete and the printer will then prompt you to run the  Color 
calibration
 procedure.
Select (using the   keys) Then press:
1. Ink Enter
2. Replace Printheads Enter
 
						

							Printhead alignmentYou should have one of the following types of paper loaded before attempting to align the printheads: HP Bright 
White Inkjet Paper (Bond), HP Coated Paper, HP Heavyweight Coated Paper, HP High-Gloss Photo Paper, HP 
Satin Poster Paper or Plain Paper. If you try to do this with any other type of paper loaded, the printer will prompt 
you to load a different type of paper before letting you align the printheads.
From time to time you may be required to align the printheads to ensure maximum print quality. To select 
Printhead Alignment manually, make sure you have the correct type of roll or sheet paper loaded. 
There are two types of alignment: Standard which will take about 4½ minutes; and Special which takes about 
11 minutes. Standard alignment is recommended for normal use and requires paper of at least A4/Letter-size, 
loaded in landscape mode. Special alignment should be used to correct printhead to paper spacing variations 
which would be shown by variations in vertical line quality, particularly in wide plots and fast print modes. Special 
alignment requires paper of at least A3/B-size, loaded in landscape mode. Two separate prints are made.
Then use the following front panel menu selections to start the alignment:
Once you have made this selection the printer starts the alignment process, which then takes several minutes.
The printer will also automatically use the standard alignment process to align its printheads after Printhead replacement
. When the alignment procedure completes after a printhead replacement, the printer asks if you want 
to run the Color calibration
 procedure.
Select (using the   keys)  Then press:
1. Ink Enter
2. Align Printheads Enter
3. Standard (4.5 minutes)
Special (11 minutes) Enter

							Solving problems• To find the meaning of front-panel messages, see Message descriptions
.
• If you know the problem is related to a certain task, first check the relevant section in this manual, for step-by- step procedures. Use this manual’s index or table of contents to find the section. For example, if you are 
having difficulty with page formatting, refer to  Page format
.
• If the problem is directly related to the quality of your printed images, refer first to  Print quality problems
.
• Refer to the appropriate topic: – Ink supply problems
– Paper problems– Communication problems– Image error– Other problems
• If the problem could be related to your software driver, and you are using an HP driver, refer to the driver’s 
troubleshooting documentation and the on-line help in your application software.
• If the problem has no obvious cause, refer to  Finding the source of your problem
.
• If you still cannot solve the problem, see  Getting help
.
 
						

							Finding the source of your problem1. Look at the front-panel display for messages. See Message descriptions
 for a full explanation of front-panel 
messages.
2. Test the printer. – Switch the printer off on the front of the printer. Make sure that the power cord is firmly inserted in the 
printer and plugged in to an outlet that you know works.
–  Switch the printer on and make sure the front-panel display shows the HP welcome screen followed by 
Main Menu after a short initialization period.
3. Test your computer hardware and interface. – Make sure that you have the correct interface cable between the computer and the printer and that it is 
firmly connected to the correct ports (see the  Assembly and Set-up Poster).
 
						

							Print quality problemsYour printer provides a full troubleshooting utility to ensure you can always quickly overcome any image problems 
you encounter. You should use this utility whenever you (and not the printer) perceive a problem with print quality. 
Often what you believe to be a print quality problem is in fact caused by incorrect configuration of the printer for 
the type of image you are trying to print. Always check Configuration correction
 as your first diagnostic task to find 
the cause of your problem.
If a message, such as “PRINTHEADS not functional” appears on the front panel of your printer, follow the 
instructions given for the particular message (see  Message descriptions
).
The types of problems you could possibly encounter are:
• Stepped lines
•Incomplete lines•Color accuracy•Horizontal banding•Color alignmentWhenever you see any of these problems, work through the  Troubleshooting procedure
 replying to the questions 
displayed on the front panel. This will lead you to correct remedial action required to solve your print quality 
problem.
 
						

							Configuration correctionBefore attempting the print quality diagnostic procedures contained in this section, you should first check that the 
printer is correctly configured to print what you want. Many problems concerned with print quality can be solved by 
correcting the way the printer is configured.
1. To achieve the best performance from your printer, only use genuine HP accessories and supplies, whose 
reliability and performance have been thoroughly tested to give trouble-free performance and best-quality 
prints. For details of HP paper, see  Paper types
.
2. Make sure that the  Type of paper selected in the front panel is the same type of paper loaded into the printer. 
To check this go to the Roll or Sheet menu in the front panel and press  Enter.
3. To ensure the maximum print quality use  HP certified paper only. For details of HP paper see  Physical 
characteristics of paper types
. You can also look at the Web page http://www.hp.com/go/graphic-arts/
 for the 
most up-to-date information.
4. Make sure that the  Print quality (Fast, Normal, Best) used for your printer is correct. This is set in the Print 
Setup dialog box of the printer driver or in the front panel from the Set-up menu. The printer driver setting 
overrides the front panel setting.
5. Select  Best print mode for maximum print quality.
6. For  Non-HP drivers , set front panel paper settings to match the paper type loaded in the printer. The 
documentation that came with your software should provide information about paper type/print quality 
settings.
7. If your print quality problem is color accuracy related, go to  Color accuracy
 for further configuration help.
