Replaceable ink service module

The replaceable ink service module holds waste ink from the black print cartridge. When it is almost full, the printer LEDs will prompt you to replace it. See LED Reference.

When the ink service module is full, the printer will stop printing. If you have a replacement for the ink service module, replace it immediately by following the instructions that come with it.

Otherwise, visit www.hp.com/support/dj450 or see Customer Support to get a replacement. In the meantime, remove the black print cartridge to continue printing. The printer can print using only the tri-color print cartridge but the color results and print speed may be affected. See Single-cartridge printing mode.

Allowing the ink service module to fill completely can result in black ink spillage.

If you have installed the Toolbox, you can choose to display error messages on your screen when there is a problem with your printer. See Installing the printer

driver (Windows and Macintosh).
