HP 720c manual Minimum Printing Margins, Cartridges and INK, Poor Print Quality, Potential Damage

MINIMUM PRINTING MARGINS

The printer cannot print outside a certain area of the page, so you must make sure the contents of your document fall within the printable area—that is, within the top, bottom, left, and right margins available for the specific size paper on which you are printing.

When you use nonstandard paper sizes and select the Custom Paper Size setting in the HP print settings box, the paper width must be between 3 and 8.5 inches (77 and 215 mm) and the paper length must be between 3 and 14 inches (77 and 356 mm).

CARTRIDGES AND INK

To get the best performance and clearest output from your printer, Hewlett-Packard recommends using only genuine HP supplies in HP inkjet print- ers. Damage resulting from the modification or refilling of HP print cartridges is specifically excluded from coverage of HP printer warranties.

Refilling an HP print cartridge pushes the electronic and mechanical components of the cartridge past their normal life cycle, creating many potential problems, such as the following:

Poor Print Quality

■Non-HP ink can contain components that cause nozzles to become clogged, resulting in streaked copy and graying or fuzzy characters.

■Non-HP inks can contain components that corrode the cartridge’s electrical components, resulting in poor printouts.

Potential Damage

■If ink from a refilled cartridge leaks, the excess ink could damage the service station that caps the cartridge while it is in the printer but not in use. Because this service station maintains the health of the cartridge, print quality problems might occur with the cartridge.

■If ink from a refilled cartridge leaks onto the electrical components in your printer, severe printer damage can occur, causing down-time and repair costs.

Caution

Damage resulting from the modification or refilling of HP cartridges is specifically excluded from the coverage of HP printer warranties.

Note

When buying replacement print cartridges check part numbers carefully so that you buy the right ones (Black–51645A, Color–C1823A).
