Question 5

Advantages of the Vertical Transport System

Answer 5

Feeds film evenly
Correct alignment of film
Alternates film side to side, ensures proper wear of rollers

Question 6

Entrance Roller Assembly

Answer 6

rollers covered in corrugated rubber

keeps film in straight line

Question 7

Transport Rollers

Answer 7

move film through chemical tanks and dryer assembly

Question 8

Turnaround Assembly consists of:

Answer 8

Master Roller
Planetary Roller
Guide Shoe

Question 9

Turnaround Roller

Master Roller

Answer 9

bottom of roller assembly
turns film from moving down to up
also called deep rollers

Question 10

Planetary Roller

Answer 10

positioned on either side of turnaround roller

aids in proper alignment of film

Question 11

Guide Plates

Guide Shoe

Answer 11

curved metal plates
positioned on either side of turnaround roller
guide film through roller assembly

Question 12

Crossover Roller

Answer 12

moves film from one tank to another and finally into dryer

Question 13

Crossover

Answer 13

space between rollers, allows for squeegee of film, removes excess liquid

Question 14

Power provided by electric current

Answer 14

Drive System

Question 15

Drive system

Answer 15

Turn all rollers and processors
powered by single motor
45-90 seconds from entrance roller to receiving bin
(varies depending on type of film)

Question 16

Drive System

Standby Control

Answer 16

improves cost effectiveness
reduces wear and tear
decreases water use

Question 17

Replacement of fresh chemicals after loss of chemicals during processing

Answer 17

Replenishment System

• chemicals eventually become exhausted
• developer and fixer need to be replaced

Question 18

Which way is film placed on feed tray in order to ensure proper replenishment?

Answer 18

Horizontal

Question 19

Over replenishment of developer causes…

Answer 19

Increase Density

Decreased Contrast

Question 20

Over replenishment of fixer causes…

Answer 20

No effect on image, But a waste in solution

Question 21

Two ways to replenish chemicals

Answer 21

1. Volume replenishment
   - for high volume workload
2. Flood replenishment
   - scheduled at time intervals
   - solution pumped into system every couple minutes on standby
   - for processors that utilize low to medium number of films

Question 22

Re-Circulation system is responsible for…

Answer 22

Agitates Solutions
Mixes old and new chemicals
Filters solution
Stabilizes temperature

Question 23

Temperature control

Answer 23

Increased Temp = increased density

Decreased Temp = decrease density

Question 24

What are the two temps of temperature control?

Answer 24

Immersion Heater: heated coils emersed in the bottom of tank

Heat exchanger: uses thermostat to heat developer
