9-9Chapter 9 Maintaining Your MultiPASS C50
Cleaning and Testing the BJ Cartridge Print Head
The print head in the BJ print 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 C50 is equipped
with a print head cleaning function that does this.
If your printouts become faint or streaked, or if their quality otherwise decreases,
clean the print head as described below.
If your printing is faded, you can often correct the problem by adjusting the print
density (contrast) and printing speed. (For instructions, see the MultiPASS
Desktop Manager User’s Guide.) Try this before cleaning the print head.
Cleaning the print head uses a small amount of ink. Cleaning too often
significantly reduces the amount of ink in the cartridge, so clean only when
necessary.

½ The MultiPASS C50 beeps once when cleaning is finished, and returns to
standby mode.
5. Check whether cleaning corrected the problem by printing the nozzle check
pattern. See page 9-8.
6. If necessary, repeat this procedure up to four more times (giving five
cleanings in all). If the problem persists after this, install a new BJ cartridge.
See ”Replacing the BJ Cartridge” on page 9-12.
