[0: 90 copies, 1: No copies, 2: 10 copies]

 90 copies: Toner end is determined if a low density image (Vref 

Vt(10)) is detected 90 times after toner near end.

 If "1" is selected, the machine stops printing when the TD sensor output drops below the prescribed level.

 Select 1 or 2 if the customer normally makes copies of very high density.

2220*

Vref Setting

Adjusts the TD sensor reference voltage (Vref). Change this value after replacing the development unit with another development unit that contains toner.

[1 to 5 / 4 / 0.01 ]

1. Check the value of SP2-220 in both the machine containing the test unit and the machine that you are going to move it to.

2. Install the test development unit, and then input the VREF for this unit into SP2-220.

3. After the test, put back the old development unit, and change SP2-220 back to the original value.

2914*

Paper Setting

001

C-alpha

[0 to 400 / 150 / 10vol ]

Adjusts the charge roller voltage used when paper with a small width is fed from the by-pass tray. The paper width below which the correction starts depends on the value of SP2-309-1.

Use this SP when an image problem (such as white spots at the center of black dots or breaks in thin black lines) occurs when paper with a small width is fed from the by-pass feed tray.

002

C-beta

[0 to 400 / 0 / 10vol ]

Adjusts the charge roller voltage used when paper with a small width is fed from the by-pass tray. The paper width below which the correction starts depends on the value of SP2-309-2.

Use this SP when an image problem (see 2-914-1) occurs when paper with a small width is fed from the by-pass feed tray.

003

B-gamma

[0 to 300 / 200 / 10vol ]

Adjusts the development bias used when paper with a small width is fed from the by-pass tray. The paper width below which the correction starts depends on the value of SP2-309-1.

Use this SP when an image problem (see 2-914-1) occurs when paper with a small width is fed from the by-pass feed tray.

004

B-delta

[0 to 300 / 50 / 10vol ]

Adjusts the development bias used when paper with a small width is fed from the by-pass tray. The paper width below which the correction starts depends on the value of SP2-309-2.

Use this SP when an image problem (see 2-914-1) occurs when paper with a small width is fed from the by-pass feed tray.

2940*

Toner consump. (SSP)

001

[0: OFF 1: ON]

[0 to 1 / 1 / 1]

If this SP is set to ON, toner bottle consumes toner when the SP2801 (TD Sensor Initial Setting) is executed. This prevents the image offset.

002

Setting

[0 to 1 / 0.06 / 0.01]

Specifies the threshold value for the toner consumption mode if SP2940-001 is set to ON.

2960*

Toner Overflow Sensor

[0 = OFF, 1= ON]

Selects whether or not the toner overflow sensor is activated.

2964*

Trans Cleaning Blade Forming (SSP)

Applies a pattern of toner to the transfer belt at a defined interval between sheets on the transfer belt in order to reduce friction between the belt surface and the cleaning blade.

Under conditions of high temperature and high humidity, the density control feature may reduce the amount of toner, which also reduces the amount of toner on the surface of the transfer belt. With less toner on the belt, the friction between the belt and the blade increases, and could cause the blade to bend or scour the surface of the belt.

001

0: OFF, 1: ON

[0 to 1 / 0 / 1 ]

002

Pattern Interval

[1 to 100 / 15 / 1 sheet]

003

Pattern Number

[1 to 3 / 1 / 1 line]

004

Pattern LD Power

[0 to 15 / 2 / 1 ]

2972*

Grayscale Limit (SSP)

Controls the halftone density level to prevent deterioration of the OPC. The halftone density is detected by the ID sensor, and the machine adjusts the intensity of the LD beam according to the upper/lower limit setting.

001

Upper Limit

[0 to 100 / 58 (C2b), 63 (C2c)/ 1vol ]

Defines the upper limit for grayscale.

A larger value allows a wider range of halftones at the pale end of the scale. If the image contains pale areas with fuzzy borders surrounded by dark areas, reduce this value to make the borders clearer.

002

Lower Limit

[0 to 100 / 52 (C2b), 57 (C2c) / 1vol ]

Defines the lower limit for grayscale.

A smaller value allows a wider range of halftones at the dark end of the scale.

2973*

Grayscale Cycle (SSP)

[0 to 1000 / 100 / 10 sheets ]

Set s the halftone operation interval in order to prevent deterioration of the OPC. If the number of copies exceeds this setting, at the end of the job, or if the door is opened and closed, charge correction is executed.

2974*

Image Density

001

Adjustment Mode

[1 to 5 / 3 / 1 ]

Adjusts image density. Changing this setting adjusts development bias and ID sensor output voltage that in turn raises or lowers image density.

2975*

Near End Setting

Detection Time

[0 to 2000 / 0 / 10 sec ]

Sets a time for toner supply motor rotation for issuing the toner near end warning on the operation panel. The time may need to be shorter for customers who run especially large print jobs (working at night, for example) to ensure earlier warning of the toner near end condition so toner out does not interrupt a long job.

2976*

Bottle Motor Time

Displays the total ON time of the toner supply motor, calculated from when the toner bottle was replaced. Use this to check that the toner end count (SP2975) is working properly.

When SP2975 is set to any value other than "0", this value is displayed when it matches the setting of SP2975. When SP2975 is set to "0", SP2976 is disabled. SP2976 is automatically set to zero by toner end recovery.)

Time

[0 to 7,000,000 / 0 / 1 msec]

2977*

Toner End Status

Indicates the toner near end or end condition.

001

2: Toner end counter > 90 when SP2213-001 is set to "0". 3: Toner end counter  90 and Vt (10)  (Vref + 0.3) when SP2213-001 is set to "0".

4: When SP2213-001 is set to "2"

5: Vsp > 0.9 when SP2213-001 is set to "2" 6: Special order

7 to 10: Not used

2980*

Charge Counter

[0 to 1000000 / 0 / 1 sheets ]

Set the number of pages to print after toner and carrier initialization before the charge input is increased to compensate for deterioration over time in the polarity of the carrier.

The strength in the polarity of the carrier in the toner will eventually decrease and cause lower charge output. Setting the charge output to increase after a specified number of copies can compensate for this effect.
