If the print head nozzles are clogged, some horizontal lines will have a broken appearance. If this happens, clean the print head.

If the ink tank is empty, some colors will not print. If some colors do not print even after you have done the print head cleaning, replace the ink tank.

If the problem persists, try replacing the BJ cartridge.

Avoid the following operations which can cause print heads to clog:

■Storing BJ cartridges that have been removed from the printer in an unsealed Ink Cartridge Storage Box. (To purchase an Ink Cartridge Storage Box, call 1-800-671-1090.)

■Touching the print head with your fingers.

■Placing the print head directly on any surface, such as a desk.

■Pulling out the power cord while the BJ cartridge access cover is open. This allows air to get into the print head and causes drying.
