Advertisement Electric Parts

The electric parts of the printer are activated when the printer is connected to the AC power supply.
At the left rear of the printer are the main controller, power supply, and interface connector. The carriage PCB is incorporated in the carriage unit, and the operation
panel is on the upper right top cover.
When serving the printer with the cover removed, be extremely careful to avoid electric shock and shorting electrical devices.

1.7.2 Other Precautions Printhead

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[1] and then remove the protective cap 1[2] and protective cap 2[3] in that order.
Do not reattach the protective cap 2[3] to the printhead because the cap may damage the nozzles[4].
To prevent the nozzles from getting clogged with foreign matter or dried ink, install the printhead immediately after you remove the protective caps.
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 with foreign matter and improper supply of ink, never touch the nozzles[4] or ink port[6], or wipe it with tissue paper
or anything else.
Do not touch Electriacl contact[5].
Also, never attempt to disassemble/reassemble the printhead or wash it with water.
If the nozzles are clogged or an ink suction problem occurs, white lines can appear on the printout a constant frequency or color dulling can occur. If this problem
is not resolved by cleaning operations, replace the printhead with a new one.
