IMPORTANT SAFETY NOTICES

PREVENTION OF PHYSICAL INJURY

1. Before disassembling or assembling parts of the printer and peripherals, make sure that the printer power cord is unplugged.

2. The wall outlet should be near the printer and easily accessible.

3. If any adjustment or operation check has to be made with exterior covers off or open while the main switch is turned on, keep hands away from electrified or mechanically driven components.

4. The printer drives some of its components when it completes the warm-up period. Be careful to keep hands away from the mechanical and electrical components as the printer starts operation.

5. The inside and the metal parts of the fusing unit become extremely hot while the printer is operating. Be careful to avoid touching those components with your bare hands.

HEALTH SAFETY CONDITIONS

Toner and developer are non-toxic, but if you get either of them in your eyes by accident, it may cause temporary eye discomfort. Try to remove with eye drops or flush with water as first aid. If unsuccessful, get medical attention.

OBSERVANCE OF ELECTRICAL SAFETY STANDARDS

1. The printer and its peripherals must be serviced by a customer service representative who has completed the training course on those models.

2. The NVRAM module (option) installed on the controller has a lithium battery which can explode if replaced incorrectly. Replace the NVRAM only with an identical one. The manufacturer recommends replacing the entire NVRAM. Do not recharge or burn this battery. Used NVRAM must be handled in accordance with local regulations.

SAFETY AND ECOLOGICAL NOTES FOR DISPOSAL

1. Do not incinerate toner bottles or used toner. Toner dust may ignite suddenly when exposed to an open flame.

2. Dispose of used toner, the maintenance unit which includes developer or the organic photoconductor in accordance with local regulations. (These are non-toxic supplies.)

3. Dispose of replaced parts in accordance with local regulations. When keepi ng used lithium batteries in order to dispose of them later, do not put more than 100 batteries per sealed box. Storing larger numbers or not sealing them apart may lead to chemical reactions and heat build-up.

4. When keeping used lithiu m batteries in order to dispose of them later, do not put more than 100 batteries per sealed box. Storing larger numbers or not sealing them apart may lead to chemical reactions and heat build-up.

LASER SAFETY

The Center for Devices and Radiological Health (CDRH) prohibits the repair of laser-based optical units in the field. The optical housing unit can only be repaired in a factory or at a location with the requisite equipment. The laser subsystem is replaceable in the field by a qualified Customer Engineer. The laser chassis is not repairable in the field. Customer engineers are therefore directed to return all chassis and laser subsystems to the factory or service depot when replacement of the optical subsystem is required.

WARNING Use of controls, or adjustment, or performance of procedures other than those specified in this manual may result in hazardous radiation exposure.

WARNING WARNING: Turn off the main switch before atte mpting any of the

procedures in the Laser Optics Housing Unit section. Laser beams can seriously damage your eyes.

Gamma Adjustment

NOTE: To solve color quality problems, clean and/or replace related parts first. If

adjustments are required, follow the procedure in this section.

Summary

To adjust the printer gamma:

• Select the print mode that needs calibrating

• Print a color calibration test sheet

• Make the gradation scales on the printout smooth from the lowest to the

highest density. Adjust the CMY gradation scale at the top of the chart by balancing the density of the C, M, and Y gradation scales – the CMY gray scale should change smoothly from minimum to maximum, and there should be no coloration.

The color adjustment sheet is as follows.

[C]

[B]

[A]

G070S013.PCX

For each color, you can adjust 15 points (example [A]) between 0 (lowest density) [B] and 255 (highest density) [C]. For each point, you can adjust the density within 0 and 255.

5-8

Page 76

17 September, 2001 SP MODE TABLES

The gradation scales marked ‘Default’ are printed according to the default gamma settings in the flash ROM in the controller. The gamma adjustment changes the densities at the adjustable points in the gradation scale. The gradation scale marked “Current” sho ws th e current settings.

During the adjustment procedure, compare the “Current” gradation scale with the ‘Default’. Select the density for each of the 15 adjustable points, excluding points 0 and 255, from the ‘Default’ gradation scale.

The NVRAM holds three sets of controller gamma settings:

• Those saved this time: ToneCtlSet - Tone (Current)

• Those saved in the previous adjustment: ToneCtlSet - Tone (Prev)

• The factory settings: ToneCtlSet - Tone (Factory).

Adjustment Procedure

1. Enter the controller service mode.

2. Use the down arrow key to select “ToneCtlSet” (the second of the two) and press the Enter key.

3. Use the up/down key to select the mode that requires calibrating, then press the Escape key until you get back to the controller service mode menu.

4. Use the down arrow key to select “PrnColorSheet” and press the Enter key.

5. Use the up/down key to select “ToneCtlSheet” (normally this is displayed by default) and press the Enter key.

6. When “Execute?” is displayed, press the Enter key to print out the “color calibration test sheet”.

7. When “Execute OK” is displayed, press the Escape key 2 times to exit from the menu. (You retu rn to “PrnColorSheet” in the controller service menu.)

8. Use the down arrow key to select “ToneCtlValue” and press the enter key.

Color Calibration

Test Sheet

Adjust the color density at each of the 15 points for each of the four colors. NOTE: 1) To decide what density value to input, do the following.

2) Look at the color adjustment sheet.

3) For the color you are adjusting, look at the gradation scale entitled ‘Default’.

4) Go along the scale until you reach the density that you wish to input.

5) Read off the value on the scale and store it in the machine. a) Use the up/down key to move the cursor along the three-digit

display, then press the Enter key.

b) Use the up/down key to change the digit at the cursor, then press

the Enter key.

c) Press the Escape key to exit from the menu.

6) Do the same for all 15 points.

10. When the density setting is complete for all colors, print out a color adjustment sheet again and make sure that the gradation scale for each printed color is smooth and that the CMY gradation scale is gray. Repeat the adjustment if there is an anomaly (normally, repeat this procedure 3 to 5 times).

11. When the adjustment results are sa tisfactory, do the following:

1) Use “ToneCtlSave” in the controller service menu, to store the new settings

in the controller.

2) Reset the controller (press the [Reset] key when the machine is off line”) to

use the new settings.

NOTE: The new settings will not be saved in the controller NVRAM unless you

reset the controller.

Specifies the settings for when fusing idling is done after printing on A4/LT LEF or smaller paper sizes. [0 ~ 2 / 0 / 1/step]

• After printing on small-width paper (A4 LEF/LT LEF or smaller), fusing idling evens the oil thickness on the roller surface.

• 0 (Int): Enables printing during fusing idling.

• 1 (NoRev): Disables this type of fusing idling.

• 2 (NoInt): Disables printing during fusing idling.
