Chapter 3 Getting Started

428TM Operator’s Manual - 880042-0141 3-37

Electrostatic discharges can cause damage to the print head, memory or electronics. This

damage will manifest itself as lost pixels on the print head, memory scrambling,

communication to the printer lost or other issues causing the printer not to function properly.

This damage can be immediate or happen over time.

When working with the USB port, it is imperative that ESD and Ground connections are

adhered to or potential disconnect issues may be encountered. We also recommend

disabling the ability to allow the computer to turn off the USB device under the Power

management.

Example:

1. Open the system Device Manager.

2. Scroll to the Universal Serial Bus Controllers and expand the listing.

3. Open the USB Root Hub’s listed (not the USB 2.0 Root Hub’s).

4. Go to the Power Management tab under the Properties.

5. Uncheck the “Allow the computer to turn off this device to save power”.

6. Select OK and repeat for the remaining USB hubs.

3.14 TOF Sensor

The TOF Sensor is used to detect when media is present and is used in conjunction with the

Top-Of-Form operation. A TOF is when the printer uses the sensor to detect the edge of

the media and retracts the configured distance. See the D121 and D123 commands for

more details regarding the TOF operation.

A potentiometer adjusts the distance over which the LPD sensor will detect reflections. The

maximum range may be adjusted over a distance of 0.20” to 0.85”. Distances are

measured from the surface of the sensor to the reflecting surface. The sensor is set to the

maximum detection at the factory. This pot may be used to decrease sensor range to avoid

false reflections from stationary objects such as a cutter.
