Page 52: Bj Cartridge Cautions
Guidelines for Using and Maintaining BJ Cartridges The most important thing you can do to ensure the best possible print quality, as well as extend the life of your MultiPASS C50, is to take care of the MultiPASS C50’s BJ cartridges following these guidelines: Store cartridges at room temperature.
Page 53 PRINT HEAD Make sure the BJ cartridge holder is in its home position (on the right side of the unit) when you are not using the MultiPASS C50. If it is not in its home position, press the CARTRIDGE button.
Page 54 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 headas described below.
Page 55 When to Replace the BJ Cartridge How frequently you need to replace your MultiPASS C50’s BJ cartridge or one of its ink tanks depends on how you use your MultiPASS C50. If you print a good deal of graphics, halftones, or greyscales, you will need to replace the cartridge more often than if you print mainly text.
Page 56 If the message CHANGE CARTRIDGE appears in the LCD display, the BJ cartridge may have run out of ink. This message also appears if the MultiPASS C50 has to store a fax in its memory because the cartridge is out of ink.
Page 57 If you remove a partially used BJ cartridge from the MultiPASS C50, store it in the SB-21 BJ cartridge container that came with your unit.
Page 58 Part 1: Facsimile b) Unpacking the BJ cartridge Do not open the BJ cartridge packaging unless you are ready to install the new BJ cartridge. Before installing the BJ cartridge, gently remove the orange head cap and the orange protective tape from the nozzles. Storing an opened BJ cartridge If the BJ cartridge packaging has been opened and the BJ cartridge is not to be installed immediately, store the cartridge in the SB-21 cartridge...
Page 59 Chapter 1: General Description c) Protecting the ink nozzles Do not touch or wipe the ink nozzles with tissue paper, etc. Doing so can clog the nozzles. If the head cap and protective tape have been removed and the BJ cartridge is not to be installed immediately, store the cartridge properly to prevent the nozzles from drying out and clogging.
