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.
