CAUTION
❏ Take proper measures to protect the printhead unit from static electricity, because the
driver IC is directly attached to the printhead unit.
❏ Never touch the printhead’s metallic nozzle cover surface. Handle it only by holding the
edges of the printhead.
❏ When you replace the printhead or the printer mechanism, you must replace the block
resistor at location RM4 (for Micro Mode - Color (R-No.)), RM5 (for Normal Mode -
Color (M-No.)), RM11 (for Micro Mode - Monochrome (R-No.)), and RM12 (for Normal
Mode - Monochrome (M-No.)) on the C162 MAIN Board. (Every spare printhead or
spare printer mechanism comes
with a block resistor that is specifically selected for each printhead. (Refer to Table 3-2.)
