INSTALLATION
This section helps you in loading the consumable media in the printer, and provides adjustment instructions
and as well as interface connection with host computer and other optional attachment units.
The following information is provided:
• 2.1 Site Location
• 2.2 Media Selection
• 2.3 How to Load the Media
• 2.4 How to Load the Carbon Ribbon
• 2.5 Connections

Section 2: Installation
Page 2-2 GZ4e Series Operator Manual
2.1 SITE LOCATION
Consider the following when setting up the printer:
• Place the printer on a solid flat surface with adequate space. Make sure there is enough space above
the printer to provide clearance for the top cover to swing open.
• Place it away from hazardous materials or dusty environments.
• Place it within operational distance of the host computer if connected, within interface cable
specifications.
2.2 MEDIA SELECTION
The size and type of the labels to be printed should have been taken into consideration before printer
purchase. Ideally, the media width will be equal to, or just narrower than, the print head. Using media that
does not cover the print head will allow the platen roller to tread on it and wear it out. The media edge will also
wear a groove in the platen roller, which can affect print quality.
This printer can print on roll or fan-fold media. The printer uses sensors to detect I-marks or Gaps on the
media in order to precisely position the print content.
Figure 2-1, Media Selection
Note:
For optimal print performance and durability, please use SATO-certified media and ribbon supplies
on this printer. Using supplies not tested and approved for use by SATO can result in unnecessary
wear and damage to vital parts of the printer, and may void the warranty.

2.3 HOW TO LOAD THE MEDIA
There are two general media types that may be loaded and used; rolled and fan-fold. Rolled media of
standard diameter is loaded within the printer and suspended by the media roll holder. Larger, non-standard
rolled media would be suspended outside the printer at its rear and fed inward. Fan-fold media would also be
fed inward from the rear but is stacked as opposed to suspended.
2.3.1 How to Load Media Roll
1. Lift up the main cover.
Note:
Make sure that the cover rests firmly so that it will not fall forward and injure your hands.
2. Adjust the green media holder guide to the widest position.
3. Load the media onto the media roll holder. Refer to Figure 2-2.
Make sure the media leader is pulled out from the bottom and the printed side is facing upwards. Push the
roll firmly towards the side of the frame.
Then adjust the media holder guide inward till the media holder guide press lightly against the media
roll.
Turn the media roll lightly by hand and confirm that it rotates smoothly. Otherwise, media may not be fed
correctly during operation.
