Cabling and Cable Routing

Always tie cable down, use locking connectors where possible, allow for kiosk component

servicing, and avoid electrical noise sources.

• Tie all cables to the kiosk chassis or printer mounting hardware that are near the

printer, the media path or media. The operator can accidentally disconnect the printer

or other kiosk components when maintaining the kiosk. Cabling must not interfere

with the proper operation of the printer and media. The operator can become caught

on cabling and drop heavy media damaging the kiosk or hurting themselves.

• Service Loops - There should be enough slack in the cabling to not put pressure on the

cable connectors or the circuit boards. Also enough slack is needed to disconnect the

printer (or their kiosk components) for servicing. Allow for movement needed to

access the cable locks or slide the printer out when using the Quick-fit hubs.

• Avoid electrical noise sources: fluorescent lighting and ballast, power supplies, fans,

AC power lines, CRT monitors, etc.

• Avoid twisting power and communication cables together. This can cause spurious

noise on the communication port or raise emissions levels.

Electrostatic Discharges and Earth Currents

Preventing ESD and earth currents from affecting the printer operation requires proper

connection of the printer chassis to protective earth through a mounting platform or through a

separate earth conductor.

Ambient Light

There is an optical sensor 20 mm behind the paper exit at the front of the printer. Other sensors

can also be affected by internal lights (and bright outside light sources entering through seams,

vents, etc.) in the kiosk. To ensure proper printer operation, design the printer enclosure so that

it prevents direct sunlight or light from indoor lamps from reaching the sensor through the

paper exit

See the Shutter Bezel on page 79 for an accessory option that has been used to shield the media

output sensor from external light sources.

Cooling

The printer needs space on both sides of the printer to allow for convection cooling of the

printer. This become more important with kiosk installing that have extreme environments and

high printer use.
