1103*Fusing Idling Switches fusing idling on/off. When on, printing will not start until enough time has elapsed so the hot roller can reach optimum temperature. This ensures even heat on the hot roller.
Switch on if fusing on the 1st and 2nd copies is incomplete (this may occur if the room is cold.). You must switch SP1103-1 ON before you set the fusing interval with SP1103-2.001 Enable Fusing Idling 0 = Off, 1 = On 002 Interval [0 to 60 / 30 / 1 sec.]
003
Idling Time at Every JobSets the machine to fusing idling only for 30 sec. for every job (when the original is set on the ARDF, when the ARDF cover is opened, etc.) and the fusing unit has reached the reload temperature (optimum temperature for operation).
[0 to 30 / 0 / 1 sec.]
0: No idling done before a job.
1104*Fusing Temperature Control On-Off/Phase Selects the fusing temperature control method. After changing this setting, be sure to turn the machine off and on again with the main power switch to enable the new setting.
[0 to 1 / 0 / 1]
0: Normal (ON/OFF control). Allows full application from ac power supply to bring the hot roller up to the target fusing temperature then shuts off.
Determines the on-time from the present temperature (detected by the thermistor on the hot roller) and the temperature of 1 cycle before.
1: Phase (hysterisis) control. Sets the upper and lower limits for the temperature; at the lower temperature the fusing lamp is on and at the higher temperature the fusing lamp is off.
Change this setting to "0" only if the user has excessive electrical noise or interference on the power supply line. Such interference can cause voltage to drop when power is applied using the ON/OFF control method.
Interference can be caused by the general poor quality of the power supply lines, or if the machine is sharing a power supply with other electrical devices such as fluorescent lights. Before changing this setting, make sure that the machine is connected to a power supply not shared by other electrical equipment.
- Selecting Phase control ("1") could cause the fusing temperature control board to emit low pitched noise
1105*Fusing Temperature Adjustment Allows adjustment of the hot roller temperature at the center and ends of the roller for the quality or thickness of the paper. The hot roller in this machine has two fusing lamps: one heats the center of the roller, the other heats both ends. Each fusing lamp can be adjusted separately.
The "re-load temperature" is the "print ready temperature". When the fusing temperature exceeds this setting, the machine can operate. Do not set up a re-load temperature (Re-load Temp. = Fusing. Temp – SP Value.) that is higher than the SP1-105-2 setting.

This SP setting determines whether SC559 is issued after three paper late jams occur in the fusing unit. After this SP code is turned on, a counter monitors the number of paper late jams that occur in the fusing unit. After the 3rd occurrence of a fusing jam, SC559 is issued and the machine cannot be used until the service technician releases the error.
- Switching the machine off/on does not reset this jam counter. The counter is reset after the cause of the jam has been removed and a sheet of paper successfully passes the fusing exit sensor.

001Development Bias [200 to 700 / 560 / 10V ] Adjusts the development bias for copying.
Use as a temporary measure to correct faint copies from an aging drum.
002ID Sensor Pattern [200 to 700 / 400 / 10V ] Adjusts the development bias for the ID sensor pattern for VSP
2207Forced Toner Supply Forces the toner bottle to supply toner at 1-second intervals for up to 30 seconds. To start, press [EXECUTE].
2208*Toner Supply Mode [0: Sensor, 1: pixel ] Selects the toner mode.
If you select "1", SP2-209-002 should be set to its default value. Use image pixel count modes only as a temporary measure if the ID or TD sensor is defective.
2209* Toner Supply Rate
001Toner Rate [10 to 800 / 60 mg/s / 5 mg ] Sets the amount of toner supplied every second by the toner supply motor. The length of time the motor remains on is determined by the data read by the TD sensor and ID sensor.
Increasing this value reduces the toner supply clutch on time. Use a lower value if the user tends to make lots of copies that have a high proportion of black.
002Correction Data [25 to 300 / 300 / 25 ] Displays the toner supply correction coefficient (K). It can also be used to adjust K, but the value is changed again when VT is measured for the next copy.
The toner supply rate depends on the amount of toner in the toner bottle. This change is corrected using this coefficient. This SP can be used to check the toner supply condition. The lower the value of K, the lower the toner density
2210*P Pattern Cycle Sets the interval between ID sensor pattern prints.
001*Job Page Count [0 to 200 / 10 / 1 sheet] Sets the interval between ID sensor pattern printing. For users that do not make many copies daily, set a smaller interval to compensate for the effects of seasonal and weather changes.
002*Forced Page Count [2 to 999 / 100 / 1 sheet] Sets the interval between ID sensor pattern printing.
Forces creation of the ID sensor pattern to prevent low density copies for customers who use the copier for long copy jobs.
2213*Toner End Setting Selects the detection type for toner end. [0 to 2 / 0 / 1 step]
[0: 90 copies, 1: No copies, 2: 10 copies]
Vt(10)) is detected 90 times after toner near end.- 90 copies: Toner end is determined if a low density image (Vref
- 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.
- Appendix: Service Program Mode Tables
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 ]- 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.
- Install the test development unit, and then input the VREF for this unit into SP2-220.
- After the test, put back the old development unit, and change SP2-220 back to the original value.
2221*Reverse Interval Drum,Transfer [0 to 2000 / 0 / 1 sheets] Adjusts the threshold for the reverse rotation of the drum and development/transfer motors. This helps the drum and transfer belt cleaning operations. This reverse rotation will interrupt a multiple printing job.
2223* Vt Display
001Current [0 to 5 / 4 / 0.01] Displays the TD sensor output voltage for the immediately previous copy.
002Average 10 copies [0 to 5 / 4 / 0.01] Displays the average of the most recent TD sensor outputs (from the previous 10 copies).
003Rate of Change [-10000 to 10000 / 0 / 1] Displays the rate of change in the TD sensor output.
004GAIN [0 to 255 / 0 / 1] Displays the GAIN value used to calculate the on time for the toner supply motor.
005Image Pixel Count [0 to 255 / 0 / 1] Displays the image pixel count.
2228*Developer Lot Displays the lot number of the developer. (The lot number is embossed on the top edge of the developer pack.)

001Upper 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.
002Lower 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.
Appendix: Service Program Mode Tables2974* Image Density
001Adjustment 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.

End[0 to 10 / 0 / 1 ]
0: Not detected
1: Vsp > 2.0
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.
