Electrostatic Discharge
Overview
ESD - electrostatic discharge - is a primary source of:
• product downtime
• lost productivity
• costly repairs
While one cannotfeelastaticchargeoflessthan3,500volts,asfewas30voltscandamageordestroy
essential components in electronic equipment.
Preventive Measures
• Always look for an ESD warning label before doing any procedure involving static-sensitive
components such as CIRCUIT BOARDS. All static-sensitive components are marked with bright
graphic labels, which frequently include instructions. Follow all label instructions.
• Wear agroundingstrap when handling static-sensitive components. Always make certain that the
clip remains attached to a properly grounded, unpainted, clean surface.
• Repair static-sensitive components at an ESD-protected work station or use a portablegrounding
mat. For help in setting up an ESD-protected work station, contact your Kodak representative.
• When moving static-sensitive components from one area to another, insert and transport the
components in ESD-protective packaging. Transparent antistatic bags are available from avariety
of manufacturers and will help shield components from ESD damage.

Speed of the PROCESSOR and Developer Temperature
Extended Mode: Use this mode for mammography films that the manufacturer has specified are suitable for
extended cycle processing. The transport speed for this mode is 50 cm (191⁄2) in.) per minute or 3 minutes and
23 seconds ± 2 sec drop time (dry to dry) for a 24 cm (10 in.) sheet of film. The developer temperature is 35˚C ±
0.3˚C (95.0˚F ± 0.5˚F). The development time is approximately 50 seconds and is based on using
Film.
Standard Mode: The Standard Mode is suitable for all mammography films. The transport speed for this mode is
76 cm (30 in.) per minute or 2 minutes and 15 seconds ± 2 sec drop time (dry to dry) for a 24 cm (10 in.) sheet of
film. The developer temperature is 33.3˚C ± 0.3˚C (92.0˚F ± 0.5˚F). The development time is approximately 33
seconds and is based on using
Kodak Min-R
M Film.
The temperature of the fixer is not adjustable.
