This section contains information on utilities for maintaining the printer.
They include:

• Calibrating Color
Clean Printheads
Whenever print quality noticeably decreases it is a good idea to perform
the “ Clean Printheads” utility either through the HP 2500C Toolbox on
your computer or from the Control Panel on the printer.
Please refer to the
Maintenance Tab of the Toolbox if you wish to clean the printheads from the
Toolbox.
The “Clean Printheads” utility consists of 3 levels of cleaning. Each level of
cleaning uses some ink to clear the printheads. It is recommended that
you start with Level 1 before proceeding to subsequent levels. Note that
Level 3 takes the longest and uses the most ink.
To run the “Clean Printheads” utility through the Control Panel:
1. Press [Menu] until DIAGNOSTICS MENU appears.
2. Press [Item] to select either CLEAN PRNT-HDS LEVEL 1, 2 or 3.
3. Press [Select] to clean printheads.
Align Printheads
Although you may not notice misalignment in your printouts, it is
recommended that you run the “Align Printheads” utility whenever the
LCD displays the message "PRNT-HDS NOT ALIGNED". This ensures that
you have the best possible print quality.
You may align the printheads either through the Toolbox or from the
Control Panel. Please refer to the Maintenance Tab of the Toolbox if you
wish to align the printheads from the Toolbox.
To run the “Align Printheads” utility through the Control Panel:
1. Press [Menu] until DIAGNOSTICS MENU appears.
2. Press [Item] until ALIGN PRNT-HDS appears.
3. Press [Select].
4. The printer will print a page with 5 sets of alignment patterns.
5. In each set (A, B, C, D or E) select the most aligned (straightest) pair of
lines (1, 2, 3, 4 or 5).
6. Enter the corresponding numbers in the Control Panel by pressing
[Value].
7. When you have entered a value for a set, press [Item] to move to the next.
