Ink Jet Print Head
This chapter describes how to insert/remove the ink jet print
head in/from the printer, how to clean the print head and
preserve optimum print quality.
Your printer is delivered with a color print head and can use
either a color print head or a monochrome print head.
ALWAYS use NEC-original Ink Jet Print Heads.
Replacing the Print Head
See also the instructions embossed on the inside of the
top cover, and illustrated in Chapter 1.
Print head removal
When replacing the print head, take care not to touch the
print head carriage shaft or the area under the print head
carriage.
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).
Ink Jet Print Head
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:
1. With the printer already powered, press Install
Cartridge, to move the print head carriage to the head
loading position (the Power and On Line light indicators
start flashing simultaneously).
The print head carriage moves to correspond to error
condition 4 on the embossed template (see Chapter 1)
and both light indicators start flashing. This position is
held for 30 seconds (60 seconds if the printer has a
monochrome 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 this is not inserted correctly .
2. Open the top cover.
