Parallelogram Image Adjustment
Do the following procedure if a parallelogram prints while adjusting the printing registration or printing margin using a trimming area pattern.
The following procedure should be done after adjusting the side-to-side registration for each paper tray station.
Use SP2-109-1 No. 14 (Trimming Area) to determine whether a parallelogram image appears. If the parallelogram pattern appears, perform the following procedure.
Replacement and Adjustment
- If the leading edge/side-to-side registration cannot be adjusted within specifications, adjust the leading/left side edge blank margin.

SERVICE PROGRAM MODE
- Never turn off the main power switch when the power LED is lit or flashing. To avoid damaging the hard disk or memory, press the operation switch to switch the power off, wait for the power LED to go off, and then switch the main power switch off.
- The main power LED lights or flashes while the platen cover or ARDF is open, while the main machine is communicating with a facsimile or the network server, or while the machine is accessing the hard disk or memory for reading or writing data.
SERVICE PROGRAM MODE OPERATION
The service program (SP) mode is used to check electrical data, change modes, and adjust values.
Service Tables
- Never turn off the main power switch when the power LED is lit or flashing. To avoid damaging the hard disk or memory, press the operation switch to switch the power off, wait for the power LED to go off, and then switch the main power switch off.
Service Mode Lock/Unlock
At locations where the machine contains sensitive data, the customer engineer cannot operate the machine until the Administrator turns the service mode lock off. This function makes sure that work on the machine is always done with the permission of the Administrator.- If you cannot go into the SP mode, ask the Administrator to log in with the User Tool and then set "Service Mode Lock" to OFF. After he or she logs in:
[User Tools] > System Settings > Administrator Tools > Service Mode Lock > OFF- This unlocks the machine and lets you get access to all the SP codes.
- The service technician can do servicing on the machine and turn the machine off and on. It is not necessary to ask the Administrator to log in again each time the machine is turned on.
- If you must use the printer bit switches, go into the SP mode and set SP5169 to "1".
- After machine servicing is completed:
- Change SP5169 from "1" to "0".
- Turn the machine off and on.
- Tell the administrator that you completed servicing the machine.
- The administrator will then set the "Service Mode Lock" to ON.
- If you cannot go into the SP mode, ask the Administrator to log in with the User Tool and then set "Service Mode Lock" to OFF. After he or she logs in:
- Never turn off the main power switch when the power LED is lit or flashing. To avoid damaging the hard disk or memory, press the operation switch to switch the power off, wait for the power LED to go off, and then switch the main power switch off.

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.

(The lot number is embossed on the edge of the developer package.) This SP mode controls the voltage applied to the TD sensor to make the TD sensor output about 3.0 V. Press "Execute" to start. After finishing this, the TD sensor output voltage is displayed.
Use this mode only after installing the machine, changing the TD sensor, or adding new developer.

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.
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.
2974* 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.
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.

001Dust Detect: On/Off Issues a warning if there is dust on the narrow scanning glass of the ADF when the original size is detected before a job starts. This function can detect dust on the white plate above the scanning glass, as well as dust on the glass. Sensitivity of the level of detection is adjusted with SP4020-2.
