Chapter 1

Introducing the Classic E.O.S.

This chapter introduces the Classic E.O.S. to the user and draws the attention to some important safety precautions.

Welcome to the Classic E.O.S.

Safety precautions

Safety compliance

Welcome to the Classic E.O.S.

The Classic E.O.S. is a processor for medical X-ray films developed by Agfa. The Classic E.O.S. cannot process rollfilms.

The Classic E.O.S. offers the following features:

■Three fast processing cycles for optimal processing quality in accordance with the film type that is used: High Throughput (HT), Intermediate Processing (IP) and Rapid Processing (RP).

■Operation of the processor can be completely customized by means of the following processing parameters:

•developer temperature,

•dryer stage,

•developer replenishment rate,

•fixer replenishment rate,

•jog-cycle function (standby developer and fixer replenishment),

•initial developer and fixer replenishment function.

■The Classic E.O.S. (‘Ecological Optimized System’) features a twin fixer tank system which reduces substantially the silver carry-over to the rinse water tank.

•After development, the exposed film enters the first fixer tank, where most of the silver is removed from the film.

•The film then is transported through the second fixer tank, to be treated again with fresh fixer.

•As a consequence, when the film is passed to the rinse water tank, silver freight carry-over will be very low.

Agfa can guarantee optimal film quality and compliance with statutory regulations only if Agfa materials are used.

It is recommended to switch the processor off:

when you do not intend to process films for the next couple of hours,

at the end of the day.

1 Place the main switch in position ‘0’.

Do not touch the switch with wet fingers!

2The water tank is drained automatically.

If the processor is used continually, the water tank will be drained automatically once per period of twenty-four hours. The default time setting is 02:00 h; the time can be changed by your local service organization. This draining operation takes approx. 8 minutes.

Chapter 3

Processing films

This chapter holds basic information on how to process films both under normal conditions and in emergency situations.

Processing films

Processing an emergency film

Recommended chemicals

Processing films

Processing a film is very easy and straightforward: you just have to place the exposed film on the feed table and feed it into the feed slot of the Classic E.O.S. The Classic E.O.S. will then process the film and deposit it in the exit tray.

The Classic E.O.S. can process all common brands of medical X-ray film suitable for machine processing. You can apply sheet films of the following sizes:

maximum width: 43,2 cm (17 inch),

smallest size: 10 x 10 cm.

DO NOT process rollfilm on the Classic E.O.S.

Processing under normal conditions

Proceed as follows:

1Check whether the processor is switched on and ready for operation.

The display should show, for example, the READY message:

5($'<

53	d&
Introduce	large sheets of blank films (cleaning films), e.g. film size

35 x 43 cm, when the processor has been on standby for an extended period of time, e.g. overnight, to remove any deposits or residue from the transport path of the film.

22

1280C GB 20001204

2 Place the sheet of film to be processed on the feed table.

Make sure that the film edge is aligned with the feed slot.

The processor accepts the film and starts processing it.

The following message is shown:

3OHDVH ZDLW

3 Wait until you hear a short beep, and the READY status message reappears.

5($'<

53 d&

You can now introduce the next film to be processed.

23

1280C GB 20001204

Processing narrow films

You can place narrow films side by side on the feed table to have them processed simultaneously.

However, make sure these films do not overlap.

You can introduce 2 sheets of 10 x 10 cm film simultaneously as shown below.

DO NOT process roll film on the Classic E.O.S.

24

1280C GB 20001204

Processing an emergency film

It may happen that you have one or more films to process at a time when the Classic E.O.S. is not completely ready for operation. This can be e.g.:

when the Classic E.O.S. is initializing and the developer has not yet reached the set temperature,

when an error status message is displayed.

Still, the Classic E.O.S. enables you to process films in these conditions. Films thus processed are referred to as ’emergency films’.

Emergency films do not always meet the quality standards of development, rinsing or fixing. In addition, the archivibility of films thus processed is not always guaranteed. Under particular circumstances, the film might be useless to make a proper diagnosis!

Proceed as follows to process emergency films:

1Check the display.

Caution: Emergency film processing is not possible if, e.g., the following message appears:

(UURU

6HH PDQXDO √

Refer to ‘Emergency film processing’ on page 75.

25

1280C GB 20001204

2 Place the emergency film to be processed on the feed table.

Make sure that the film edge is aligned with the feed slot.

You can place narrow films side by side on the feed table to have them processed simultaneously. However, make sure these films do not overlap.

The processor accepts the film automatically and displays the following message on the control panel:

(PHUJHQF\ ILOP 3OHDVH ZDLW

3Wait until you hear a short beep.

You can now introduce the next emergency film to be processed.

26

1280C GB 20001204

Recommended chemicals

The tables below list the recommended chemicals, as a function of the processing cycle, temperature level and the replenishment quantity.

Chemicals		Developer and fixer temperature
	HT		IP		RP
Developer G 138 i	38 ° C		37 ° C		34 ° C
Fixer G 334 i/	34 ° C		34 ° C		34 ° C
G 338
Chemicals		Replenishment quantity
			HT / IP / RP
Developer G 138 i			400 ml/m2
Fixer G 334 i/			400 ml/m2
G 338

The replenishment quantities as listed in the above table are valid only if your film consumption exceeds 5 m2 film/day and is based on a regular daily use. If your daily film consumption is lower, you can initiate a chemical jog cycle, which provides additional replenishment rates that compensate for low film usage.

When handling chemicals, make sure to take notice of the warning instructions on the packing material. Refer to ‘Special instructions for the handling of chemicals’ on page 8.

Refer to chapter 4, ‘Customization’.
