quality by allowing the timely replacement of the print head.

shaft nor the area under the print head carriage.

Print head removal

The print head is removed to replace it, to change from a monochrome to color
print head or vice versa, or to repeat its insertion (see the section entitled
"Print head insertion" in the Quick Start), in the case of faulty printing.
When the printer is not powered or is in standby mode, the print head carriage is
in its rest position (at the extreme left).
If the printer is already powered and a print operation is running, press the On
Line key to interrupt printing BEFORE opening the top cover.
To return the printer to operating status, close the top cover and press the On
Line key.
To remove the print head, proceed as follows:
With the printer already powered, press <B><N>Install Cartridge to move the
print head carriage to the head loading position (the Power and On Line LED's
start flashing simultaneously).
The print head carriage moves to correspond to error condition 4 on the
embossed template (see Chapter 1) and both LED's start flashing. This
position is held for 60 seconds (30 seconds if the printer has a color print
head), after which the print head carriage returns to its rest position *.
To return the print head carriage to the cartridge replacement position, just
press Install Cartridge.
* The print head will not return to its rest position if there is no print
head inserted or if the print head selection lever is not in the correct
position.
