2.1.1 How to handle the printhead

Do not open the printhead package until you are ready to install the head.
When installing the printhead in the printer, hold the knob, and then remove the
protective material and protective cap, in that order. Do not replace the protective cap
once you have removed it from the printhead, since the cap may scratch the nozzles.
To prevent the nozzles from getting clogged with foreign matter or dried ink, install the
printhead immediately after you remove the protective cap. Also make sure to press
down the locking lever of the printhead until you feel a click.
In addition, to prevent clogging of the nozzles, never touch the nozzle unit or ink
supply unit of the printhead, or wipe it with tissue paper or anything else. Also, be
careful not to touch the electrical contact.
Never attempt to disassemble the printhead or to wash it with water.
If the nozzles are clogged or purging operation is poor, white horizontal
lines can appear in the printed output. If the problem is not resolved by
cleaning operations, replace the printhead with a new one.
