HP Photosmart C6340 All-in-One Printer - Manual (Page 125)

• Turn off the HP All-in-One by pressing the On button located on the product. Wait
until the On light turns off before unplugging the power cord or turning off a power
strip. If you improperly turn off the HP All-in-One, the print carriage might not return
to the correct position causing problems with the ink cartridges and print quality
issues.
• Store ink cartridges at room temperature (15.6-26.6° C or 60-78° F).
• If you notice a significant decrease in print quality, check the estimated ink levels
remaining in the ink cartridges. Replace any ink cartridges that are low on ink. If none
of the ink cartridges are low, clean the printhead.
• Do not clean the printhead unnecessarily. This wastes ink and shortens the life of the
cartridges.
• Handle ink cartridges carefully. Dropping, jarring, or rough handling during installation
can cause temporary printing problems.
• If you are transporting the product, do the following to prevent ink leaking from the
print carriage or other damage from occurring to the product:
◦
Make sure you turn off the product by pressing the On button.
The print carriage should be parked on the right side in the service station.
◦ Make sure you leave the ink cartridges and printhead installed.
◦ Lightly pack the inside of the product with crumpled newspaper to prevent the
print carriage from moving during transportation.
◦ The product must be transported sitting flat; it should not be placed its side, back,
front, or top.

Check the estimated ink levels
You can easily check the ink supply level to determine how soon you might need to
replace an ink cartridge. The ink supply level shows an estimate of the amount of ink
remaining in the ink cartridges.
NOTE: If you have installed a refilled or remanufactured cartridge, or a cartridge that
has been used in another printer, the ink level indicator might be inaccurate or
unavailable.
NOTE: Ink level warnings and indicators provide estimates for planning purposes
only. When you receive a low-ink warning message, consider having a replacement
cartridge available to avoid possible printing delays. You do not have to replace the
cartridges until the print quality is unacceptable.
NOTE: Ink from the cartridges is used in the printing process in a number of different
ways, including in the initialization process, which prepares the product and cartridges
for printing, and in printhead servicing, which keeps print nozzles clear and ink flowing
smoothly. In addition, some residual ink is left in the cartridge after it is used. For more
