Maintaining BJ Cartridges
Cleaning and Testing the BJ Cartridge Print Head
One of the most important elements in maintaining your MultiPASS
regularly, and to replace the BJ ink cartridges and tanks promptly when
needed.
The print head in the BJ print cartridge contains nozzles
ink is propelled onto the paper. To maintain the best possible print
quality, these nozzles need to be rleaned from time to time. Your
does this.
If your printouts become faint or streaked, or if their quality otherwise
decreases, clean the print head as dcscribcd 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
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.
