CAUTION
•
Assembling and disassembling of the printer are possible only for the parts
whose disassembling procedures are shown in the operation manual. Do not
disassemble any frame parts or parts whose disassembling procedures are
not shown in the manual.
Doing so may cause trouble that cannot be restored, as the printer is originally
assembled in the factory with a high accuracy of 1/100 mm.
•
Do not touch the elements on the circuit board with bare hands.
Doing so may cause static electricity and break the elements.
•
Do touch the nozzle of the print head. Be sure that the nozzle does not get any
dust.
•
There is some remaining ink in the tubes. Be careful that the ink is not spilled
from the tube onto the printer or items close to the printer.
•
If you need to operate the printer with the cover removed for maintenance, be
careful not to get hurt by the moving parts.
•
Do not oil the printer mechanism with oil other than that designated by
MUTOH. Doing so may damage the parts or shorten the lifetime.
•
If the power substrate assembly needs to be removed, disconnect the power
cable and wait for at least 5 minutes before taking it out; this will discharge the
residual electrical charge of the electrolytic capacitor.
Touching the substrate before the capacitor discharges may cause electric
shock.
•
When connecting or disconnecting the FFC type cable from the connector of
the main substrate assembly, be sure to connect or disconnect the cable
straight out from the connector.
Connecting or disconnecting at a slant angle may damage, break or shortcircuit the inner terminal of the connector. That may damage the elements on
the substrate.
•
When connecting or disconnecting the FFC type cable from the connector of
the CR substrate, be sure to connect or disconnect the cable straight out from
the connector.
Connecting or disconnecting at a slant angle may damage, break or shortcircuit the inner terminal of the connector. That may damage the elements on
the substrate.
•
Perform adjustment of the capping position before using the printer.
Otherwise it will cause dysfunctional performance of the printer such as
cleaning being performed at the wrong position.
•
Insure the following when performing cutter blade durability operation.
• Install the usable ink cartridge.
• Insure that media initialization is finished.
Performing the cutter blade durability operation with the ink cartridges
unloaded may damage the printer as the cutter blade may be down outside of
the cutting range.

•
Insure the power of the printer is OFF before performing the parameter
backup. Performing the parameter backup with the power ON may damage the
main substrate or the data may not be properly installed.
•
Insure the power of the printer is OFF before installing the firmware. Installing
the firmware with the power ON may damage the main substrate assembly or
the data may not be properly installed.
•
Insure there is sufficient space around the printer when performing
maintenance work.
•
Maintenance must be done by more than one person for the following work.
• When detaching the printer from the stand or attaching it.
• When packing the printer for transportation.

2 Product Overview
2.1 Introduction
This chapter explains the features, part names, and functions of the printer.
2.2 Features
The features of the printer are explained below.
(1) High speed output
Both models use a newly designed high-speed print head, with an improvement of up to 6 times the speed
of previous models. Also, the PJ-1614NXE can print up to a maximum width of 1600mm, and the PJ2216NXE can print up to a maximum of 2159mm in width.
(2) Outstanding weather resistance
With the specially developed solvent-type ink, the output product can last up to 3 years even without
lamination. Not only is delivery time reduced, but total cost is reduced as well.
(3) Wide variety of compatible media
Because the height of the head can be adjusted, several types of media including 0.08-1.0 mm Terpolin,
cloth, and marking film can be selected.
(4) Vibrant Color Reproduction
To reproduce clear and vibrant colors, the PJ-1614NXE uses 4 colors, and the PJ-2216NXE uses 6
colors. Both models uses 2000cc ink tanks, allowing continuous operation, and raising productivity.
(5) Effective usage of media
A JOG feature is provided to allow setting of the printing position as required. Because printing can be
performed on media that has already been printed on, excess space can be used effectively.
