SERVICE MANUAL

Calibration

Overview

Calibration is a method of ensuring consistent image appearance despite differences in film emulsions and variations in the chemistry for the processor. Calibration also provides consistent filmed images regardless of which PRINTER or processor is used.

The LASER PRINTER can store 11 calibration settings. When the PRINTER is taken off-line, the CONTROL

PANEL displays the calibration number of the previous calibration.

The user calibrates at any time and stores and prints images during calibration. If the user calibrates while the

LASER PRINTER is printing, the new calibration takes effect only when all copies of the current page are printed.

4–2 10FEB97 – SM3226-1


When to Calibrate

In general, the LASER PRINTER provides consistent output. For optimal quality assurance, however, it is suggested that the LASER PRINTER be calibrated when you change:

• the film emulsion

• the processing environment--for example, the chemistry or temperature of the processor

• the density setting

• the battery on the SEQUENCE BOARD

• the SEQUENCE BOARD.

H129_0034ACB

To determine if the emulsion number has changed, locate the label on the side of the box of film.

Calibrating the Printer

The PRINTER can store up to 11 sets of 9 density values under Calibration numbers 1-11.

Important

• Use this procedure to set new density values and to store those values under a calibration number 1-11.

• To check and select previously stored density values under calibration number 1-11, see “Checking Stored

Calibration Settings” on Page 4–11.

[1] Check that the LASER PRINTER and the processor are warmed up.

Note

The CONTROL PANEL displays the message [00 PRINTER READY].

Tone Scaling

Important

• Before doing a Tone Scale adjustment, check that the Imaging Device Monitor has been correctly adjusted. This

Monitor adjustment should not be changed once the Tone Scaling has been completed.

• Tone Scale adjustments should only be done by trained personnel.

Tone Scaling is a technique of making printed images match the images on the input monitor. To adjust the tone scale, use the following procedure:

[1] Check that the Density is set for the desired maximum density using the Setup Procedure beginning on

Page 4–22.

[2] Calibrate the PRINTER using the Calibration Procedure on Page 4–4.

[3] Use the Keypad [Program] key to adjust the Curve Shape. If necessary, see the User Manual, 5B9622.

Important

After energizing the PRINTER, wait at least 10 minutes before adjusting the SENSORS.

Film jam errors will occur if the voltages for the FILM SENSORS are not within the correct specification. Use this set of procedures to eliminate film jam errors caused by manufacturing changes in film, other film manufacturers, misadjusted or newly installed FILM SENSORS.

Important

To check and adjust PHT 1,2,3, use the procedures on Pages 5-9 through 5-14. If you achieve the signals shown on

Emitter Pulse Duty Ratio for IL1, IL2, and IL3

Duty Cycle Ratio is defined as percent of time the SENSORS are on divided by the percent of time the SENSORS are off.

Lower the Duty Cycle Ratio if film fogging has occurred. Adjusting the 3 SWITCHES changes the ratio of emitter time per cycle. The Duty Ratio may need to be changed when non-Kodak films are used.

Note

The switches RSW1 and RSW2 on the DRIVER BOARD are factory-set to 8 for a Duty Ratio of 60%. RSW3 is factory set to 3 for a Duty Ration of 28 percent.

2-Phase Pulse Motor Board (2PMD), Slide Base Motor Voltage

Use this procedure after installing a new SLIDE BASE MOTOR BOARD. The SLIDE BASE MOTOR and the

BEAM SPLITTER MOTOR operate with the same type of circuit board, the 2-Phase Pulse Motor Board. There are no electrical adjustments for the BEAM SPLITTER MOTOR BOARD.

Note

There are three versions of the 2PMD. The version depicted here contains checks and adjustments. This version can also be used for the SLIDE BASE MOTOR and BEAM SPLITTER MOTOR. The other two versions do not have adjustments and cannot be interchanged between the SLIDE BASE MOTOR and BEAM

SPLITTER MOTOR.
