MultiPASS C530/C560 Chapter 1: General Description
a) General precautions
Lubrication points
Do not touch the greased parts of the carriage guide frame, carriage shaft, idler roller and some parts.
Doing so will wipe off the grease which has been applied for the smooth operation of the printer unit.
Do not apply grease to any unspecified parts and surfaces. If grease is on the purge
section’s rubber cap or the wiping assembly’s blade, it may cause the BJ cartridge’s
nozzles to clog, rendering the BJ cartridge unusable. Also, do not use any grease other
than the specified type. Using a different type of grease may dissolve or deform plastic
parts.
If you accidentally touch a greased surface, reapply the grease. See the
PARTS
CATALOG (provided separately)
.
Spurs
During servicing, be careful not to damage or deform the spur assembly’s spur tips. If the spur tips are
deformed, the area of the paper coming into contact after the printing increases, causing vertical black stripes
on the paper.
Carriage ribbon cable assembly
Do not pull or bend the carriage ribbon cable more than is necessary. Doing so may disrupt the
cable’s continuity and prevent the printing signals to be sent properly to the cartridge.
Power off during printing
During servicing, do not disconnect the power cord during a printing operation or while the cartridge
is being replaced. Otherwise, the cartridge will stop at a position where the ink nozzles cannot be
protected by the rubber cap. The ink may then dry and clog the nozzles. During servicing, be sure the
cartridge is properly positioned for nozzle capping.
