INTRODUCTION
NOTE: Zebra technologies Corporation is not liable for personal injury or damage to
any equipment caused by the improper installation of this equipment to any power
source.
The MMQ4 Mobile Mount system is designed to integrate a Zebra™ QL 420 Printer and a
Zebra RCLI-DC Mobile Charger into the electrical and mechanical systems of a vehicle.
Once installed it will provide intelligent charging capabilities for the printer’s battery and
protection from accidental damage to the printer.
The RCLI-DC series of Mobile Chargers are supplied separately from the Mobile Mount
installation Kit. They should be installed in accordance with their installation guides and
under the supervision of properly trained and qualified personnel. The following installation
instructions pertain only to the mechanical installation of the MMQ4 mobile mount. Follow
them closely to ensure safe, reliable performance of the QL 420 Printer in a mobile
environment
The printer is powered with its own battery which is charged by a RCLI-DC Series Mobile
Charger System which runs off the vehicle’s DC electrical system. Refer to the RCLI-DC
charger installation Guide for more detail on their use and installation.
It is important that the vehicle’s electrical system be functioning properly. The vehicle’s
charging circuit must work properly and vehicle-generated electrical “noise” must be
minimized and within specifications.
The vehicle charging circuit must neither undercharge nor over-charge the vehicle battery.
Defective ignition wiring, damaged insulation, or faulty vehicle electrical components can
cause electrical noise and excess electrical noise can be severe enough to defeat the
electrical filtering that is built into the printer. When this happens, computers and printers
can behave unpredictably.
NOTE: All of these systems must be connected in strict accordance with the
instructions in this document. Failure to install this equipment per these instructions
will void the warranty.

INTRODUCTION TO INSTALLATION
The MMQ4 Mobile Mount allows you to mount a QL 420 printer into virtually any vehicle.
The RCLI Mobile Charger (supplied separately from this kit) can provide a source of power
to run and charge the printer’s battery from the vehicle’s electrical system.
Installation of the Mobile Charger is covered in the RCLI-DC Mobile Charger Installation
Guide supplied with each charger.
In all installations, the power cable is wired to the vehicle’s battery power system indirectly
through a power take-off point.
CAUTION: Under no circumstances should the equipment be attached directly to
the vehicle’s battery or an AC power sourcewithout a proper fuse.
Since each situation or equipment type may pose unique requirements, mounting hardware
selection and mechanical installation shall be the responsibility of the installer. Zebra
recommends using self-locking (ESN) nuts, bolts, and/or lock washers for installing the
mount. The mount is pre- drilled for 1/4” (M6) hardware.
NOTE: Hardware used to secure the Mobile Mount to the vehicle is not supplied in
the kit. Recommended fasteners are 1/4” (6 mm) diameter hex head or socket
head bolts with flat washers, lock washers, nuts and/or locking nuts.
Your tasks are to:
• Mechanically install the MMQ4 Mobile Mount
• Install the Mobile Charger (if used in this installation) according to the RCLI-DC
Mobile Charger Installation Guide
• Connect the Data I/O cable from the data terminal (if used) and the output cable
from the Mobile charger.
Decide where you will mount the printer, then proceed with the following instructions.
Installing a Terminal
You most likely will be installing a terminal at the same time. Follow the terminal
manufacturer’s instructions for installing his unit. The printer and terminal usually are linked
together with a data cable which typically is no longer than six (6) feet (183 cm).
Some installations may require the terminal and printer to communicate via radio frequency
pg. 4 of 12
AM16629-1 Rev. C
(RF) rather than cables.
Plan your installation with these considerations in mind, and locate the printer so that the
operator can easily load printing media and operate the printer’s controls.
MOBILE MOUNT MECHANICAL INSTALLATION
The MMQ4 Mobile Mount provides two basic mounting
options, to allow maximum flexibility in location. The
RCLI-DC Mobile Charger module is shipped
separately. The Mobile Charger is mounted
external to the Mobile Mount, depending on the
individual location’s requirements.

Attaching the Fanfold Bin
If the printer will be using fanfold media, you must install the fanfold bin to the Mobile
Mount. Hook the lip on the back of the tray to the corresponding “hooks” on the mobile
Mount. Install a 1/4- 20 Hex head screw to the back of the center bar on the Mobile Mount
which supports the fanfold bin and tighten it to secure the bin.
Loading Media
Follow the loading procedures found in the QL 420 User’s Guide. Note that if you are using
Fanfold media, you must install the Fanfold Spacer (p/n BA16625-1) between the printer’s
media supports. The Spacer is included with the MMQ4 Mobile Mount Kit.
Note: The Mobile Mount is designed for a maximum loading of 12 lbs [5.4kg] including
the weight of media. Ensure no extra items are suspended from the Printer, the
Mobile Mount Bracket of the Fanfold bin.
Printer Removal:
There is no need to remove the printer from the Mobile Mount during normal use and
cleaning. All access doors and controls can be reached with the printer secured in the
mount.
To remove the printer for servicing or repairs:
• Un-plug the power cable and the data I/O cable (if installed.)
• Remove the (4) mounting screws and their associated hardware. You can access
the mounting screws through access holes in the Mobile Mount bracket.
FINAL CONNECTIONS
If you are communicating data to the QL 420 with a cable you must connect a “Data I/O”
cable between the terminal and the printer. If desired, you can use one of the supplied
cable clamps and a #6-32 x 1/4” screw to hold the cable in position. Consult the factory for
information on the various I/O data cables offered by Zebra for use with a variety of widely
used terminals.
NOTE: This unit was tested with shielded cables on the peripheral devices. Shielded
cables must be used with the unit to insure compliance
Notes on Mobile Charger Installation
NOTE: Always refer to the RCLI-DC Mobile Charger Installation Guide for complete
information on installing the Mobile Charger.
Charger Location
Locate the Mobile Charger in a location convenient to the printer. Follow these guidelines:
• Select a location in the vehicle that will avoid personal contact in case of an accident.
• If you are using the Mobile Charger in conjunction with an MMQ4 Mobile Mount, place
the Charger so that you can easily unplug the charger’s output cable from the
Printer’s battery connection.
• Route the charger’s output cable to prevent undue strain being placed on the connec-
tion to the printer’s battery.
• Make sure that cable routing does not invite damage to the cable.
• Secure the Charger with #6 (3mm) hardware using the mounting flanges molded into
the Charger cover. Insure that the mounting hardware will not become loose due to
vibration by using locking hardware or prevailing torque fasteners.

AM16629-1 Rev. C
Connect the Printer
• Plug the output cable from the Charger to the battery connection on the printer. (Re-
fer to the QL 420 User’s Manual for more information.) If you are using a MMQ4
Mobile mount, it may be easier to plug in the charger connector before mounting the
Printer to the Mobile Mount bracket.
• Turn the power source for the charger on, and verify that the indicator lights on the
Charger’s front panel are lit and the Charger is functioning properly. Refer to Table 1
in the RCLI Mobile Charger Installation Guide for indicator display information.
CONNECTING A TERMINAL
If you are also installing a terminal in the vehicle, you normally must run two separate
cables from the vehicle power source: one to the printer and one to the terminal. The
terminal power cable must be either supplied by the terminal manufacturer or fabricated by
the installer.
It is the installer’s responsibility to determine the suitability of running a terminal from the
vehicle’s battery.
NOTE: Zebra Technologies Corporation is not liable for personal injury or damage to
equipment caused by improper installation to any power source.
