At the production line, the output power of the scanner unit is adjusted to 0.33 MILLI-WATT PLUS 20 PCTS and is maintained constant by the operation of the Automatic Power Control (APC). Even if the APC circuit fails in operation for some reason, the maximum output power will only be 15 MILLI-WATT 0.1 MICROSEC. giving an acceptable emission level of 42 MICRO-WATT which is still-less than the limit of CLASS-1 laser product.

Caution

The fusing unit is hot. Exercise care when inspecting it.

Do not switch the printer rapidly on and off. After turning the printer off, wait 10 to 15 seconds before turning it back on.

Printer power must be turned off before installing any supplies.

(5) Selection between the ON LINE mode

and the OFF LINE mode (AL-840 only)

In the ON LINE mode, the ON LINE lamp lights up to show that the machine is ready for receiving print data from the host. During copying, the machine is in the OFF line mode and the ON LINE lamp goes off. During printing, when copy interruption is made, printing is interrupted and the ON LINE lamp blinks. When a certain time passes after completion of copying, the machine go back to the ON LINE mode and printing is resumed. In any case, copying takes priority over printing. The timing to going back to the ON LINE mode after completion of copying can be set by the user program. When the clear key is pressed twice, the machine goes into the ON LINE mode immediately.

(6) Paper width detection and machine

operation (AL-800/840)

This machine is designed to detect only the following two sizes: Max. paper size and Min. paper size shown in the table below. Imaging (main scanning direction void area and image length) is performed according to the paper size the machine detects, Therefore, if the SIM 26-6 set value is not matched with the paper specification, the image position on the paper is shifted to cause a trouble.

The copy magnification ratio must be adjusted in the main scanning direction and in the sub scanning direction. To adjust, use SIM 48-1.

(1) Outline

The main scanning (front/rear) direction magnification ratio adjustment is made automatically or manually.

Automatic adjustment: The width of the reference line marked on the shading correction plate is scanned to perform the main scanning (front/rear) direction magnification ratio adjustment automatically.

Manual adjustment: The adjustment is made by manual key operations. (In either of the automatic and manual adjustments, the zoom data register set value is changed for adjustment.)

The magnification ratio in the sub scanning direction is adjusted by changing the carriage (scanner) scanning speed.

(2) Main scanning direction magnification ratio

adjustment

∗ Cases when the adjustment is required

1) When the MCU PWB is replaced.

2) When the EEPROM in the main PWB is replaced.

3) When "U2" trouble occurs.

4) When repairing or replacing the optical section.

6) Check that the copy magnification ratio is within the specified range. If it is not within the specified range, perform the following procedures.

7) Execute SIM 48-1 to select the main scanning direction copy magnification ratio adjustment mode. To select the adjustment mode, use the copy mode select key.

In the case of the automatic adjustment, when the PRINT switch is pressed, the mirror base unit moves to the white plate for shading to scan the width of the reference line, calculating the correction value and displaying and storing this value.

After execution of the automatic adjustment, go out from the simulation mode and make a copy to check the magnification ratio.

If the magnification ratio is not in the specified range (100±1.0%), manually adjust as follows.

(1) Lead edge adjustment

1) Set a scale to the center of the paper lead edge guide as shown below, and cover it with B4 or 8 1/2" x 14" paper.

2) Execute SIM 50 - 01

3) Set the print start position (AE lamp ON) (A), the lead edge void amount (TEXT lamp ON) (B), and the scan start position (PHOTO lamp ON) (C) to 0, and make a copy of a scale at 100%.

4) Measure the image loss amount (R mm) of the scale image. Set C = 10 X R (mm). (Example: Set the value of C to 30.) When the value of C is increased by 10, the image loss is decreased by 1mm. (Default: 50)

5) Measure the distance (H mm) between the paper lead edge and the image print start position. Set A = 10 X H (mm). (Example: Set the value of A to 50.) When the value of A is increased by 10, the image lead edge is shifted to the paper lead edge by 1mm. (Default: 50)

6) Set the lead edge void amount to B = 50. When the value of B is increased by 10, the void amount is increased by about 1mm. For 25 or less, however, the void amount becomes zero. (Default: 50)

48 01 Magnification ratio adjustment and black level adjustment in the front/rear (main scanning) direction and in the scan (sub scanning)

direction (1) Front/rear direction magnification ratio auto correction: The width of the reference line marked on the shading correction plate is

scanned to perform the front/rear (main scanning) direction magnification ratio automatically. In addition to the automatic magnification ratio adjustment, the OC/document center offset value and the image scan start position are also set automatically. Moreover, the black level auto correction is performed simultaneously. Since there are other simulation codes which can be set manually, the OC/document center offset value and the image scan start position which are set automatically in this simulation can be checked with the corresponding code.

OC/document center offset → SIM50-10 Center offset adjustment Image scan start position → SIM50-01 Lead edge image position

(2) Front/rear direction magnification ratio manual correction: The front/rear (main scanning) magnification ratio is adjusted by key

input. (The adjustment is made by changing the set value of the ZOOM DATA register for AISC.)

(3) Scanning direction magnification ratio correction: The scanning direction magnification ratio in the OC mode is adjusted by key

input. (This adjustment is made by changing the scanning speed.) (Operating procedure) When this simulation is executed, the current set value is displayed in two digits (Center value: 50). Press the copy mode select key to switch the setup mode and the setup display.

In the case of the front/rear direction magnification ratio and black level automatic adjustment:

To perform the automatic adjustment, put a gray gradation chart (UKOG-0162FCZZ) facedown at the left center of the platen so that the side of density 10 (black side) comes on the left side of the OC section. The black level adjustment is the same as SIM63-02 operation.

When the PRINT switch is pressed, the mirror base unit is moving to the white plate for shading. The reference line width is scanned, and the correction value is calculated and displayed, and saved. After completion of the automatic adjustment, when the density adjustment Down key is pressed, the display is changed to the black level display in 12bit hexadecimal number (3 digits).

In the case of the manual adjustment:

Enter the adjustment value with the copy quantity set key and press the PRINT switch, and the entered set value is saved and a copy is made. When the CLEAR key is pressed instead, the entered value is saved and the simulation is terminated. (When the set value is increased by 1, the magnification ratio is increased by 0.1%.)

In the front/rear direction magnification ratio auto correction:

(1) When the calculation result of the scanning correction value is ±5% or more, "- -" is displayed.

(Cause) Improper position of the reference line on the white plate, improper installation of the lens unit, etc.

(2) In case of scanning error of the reference line, the jam lamp lights up.

(Cause) CCD error, no white plate, etc.

∗ If the automatic correction of the magnification ratio is not effective, use the manual correction.

1. Set the print start position (A), the lead edge void quantity (B) and the scan start position (C) to 0, and make a copy at 100%.

2. Measure the image loss quantity (R mm) of the scale.

Set C = 10 × R (mm) (Example: Set 40.) When the value C is increased by 10, the image loss is decreased by 1mm. (Default: 50)

3. Measure the distance (H mm) from the paper lead edge to the image print start position.

(Example)

Distance from the paper lead edge to the image lead edge: H = 0 to 3mm

Image loss: R = 1 to 4mm

Set A = 10 × H (mm) (Example: set 50) When the value A is increased by 1mm, the image lead edge is shifted to the paper lead edge by 1mm. (Default: 50)

5mm

4. Set the lead edge void quantity to B = 50 (2.5mm). (Default: 50) When the value B is increased by 10, the void is increased by about 1mm. (When set to 25 or less, the void becomes zero.)

46 -1 Purpose Adjustment

Function (Purpose)

Section

Item Picture quality Density

Operation/ Procedure

Used to adjust the copy density. (The print density in each mode and the overall print density (overall setting of the specified density gradient) can be adjusted.

By adjusting the exposure level of the center density, the other copy density levels (density levels 1, 2, 4, 5) can be automatically calculated and adjusted. The gamma curve (gradient) is fixed and cannot be changed. By changing the adjustment value, however, the gamma curve is shifted (with the fixed gradient). Therefore, the overall copy density is changed. The above adjustment is made for each copy mode. Each copy mode and each copy density level (5 steps) have their own gamma curve (gradient). The adjustment value can be set in the range of 0 ~ 99.

1) Select the picture quality mode with the copy picture quality mode select key. (The currently set copy density adjustment level is displayed on the copy quantity display.)

2) To change the copy density, change the adjustment value and press the start button. (The adjustment value is stored and a copy is made.) To decrease the copy density, decrease the adjustment value, and vice versa.

In the case of the main scanning direction copy magnification ratio adjustment (auto) mode, the adjustment is made automatically and there is no need to adjust. Without entering the adjustment value, press the start button. There are two marks on the shading correction plate, and the distance between the two marks is read by the CCD to adjust the main scanning direction copy magnification ratio automatically. In case of the mark reading error, "- - -" is displayed on the copy quantity display. At that time, the main scanning direction image position adjustment is also made automatically. If, however, automatic adjustment is not made, manual adjustment must be made.

When the adjustment value is changed by "1," the copy magnification ratio is changed by 0.1%.
