Maintenance
Testing and Cleaning the BJ Cartridge Print Head
The print head in the BJ cartridge contains nozzles through which ink is
propelled onto the paper. To maintain the best possible print quality,
these nozzles need to be cleaned from time to time. Your MultiPASS C70
is equipped with a print head cleaning function that does this.
Printing the Nozzle Check Pattern
Before cleaning the print head, you may want to print the nozzle check
pattern to test the BJ cartridge installed in the MultiPASS C70. This test
shows if each print head nozzle is operating properly.
Follow this procedure to print the nozzle check pattern:
1. Press Function.
2. Press Cleaning.
3. Press Set.
❏ The MultiPASS C70 prints the nozzle check pattern.
When the BC-21e Colour BJ cartridge is installed, the pattern includes
all four colours; yellow, magenta, cyan, and black. In the colour pattern,
you will notice that lines are missing between the colours. This is
normal.
