Page 156 Di-C1.5 Training Development Unit Storage If the development unit was stored at more than 40°C, the developer can become solid. If this occurs, you will get a developer initialization error at installation. At this time, you must do the following procedure: You should also do this procedure when you install a new development unit.
Page 157: Refresh Mode
Di-C1.5 Training Refresh Mode While making prints with low coverage, the developer is agitated with less toner consumption and the toner carrier attraction tends to increase. This may cause low image density or poor transfer (white dots). To prevent this, the coagulated toner or overcharged toner must be consumed.

But, sometimes, process control adjusts the toner density too slowly, and the first few copies after process control have incorrect toner densities.
Page 174 Di-C1.5 Training Toner Density Adjustment Mode What is Done? The machine makes sensor patterns and checks the current development gamma. Development gamma too low: If the following condition occurs, the machine increases the toner density. To do this, it supplies toner to the development unit.

Pixel counter: Counts pixels to determine how much toner for each color is used on the page The result of toner supply control determines how long the toner supply motor turns on for.
Page 179 Di-C1.5 Training Toner Supply Control Modes This machine uses 5 toner supply modes. The mode used depends on SP3-044-001 to –004. These are the five modes: PID control mode PID control mode with fixed VT Fixed supply mode MBD control mode: This is the default mode. MBD control mode with fixed VT You can select a different mode for each color, if necessary.
Page 180 Di-C1.5 Training Toner Supply Control PID control mode Uses the TD sensor, ID sensor, and pixel count. VTREF is adjusted by process control. PID control mode with fixed VTREF Change to this mode if the ID sensor breaks. This mode uses only the TD sensor. VTREF is fixed at the value stored in SP3-222-001 to –004.

Page 185 Di-C1.5 Training Overview Toner Bottle Development Unit Toner End Sensor TD Sensor To supply toner, the toner bottle is rotated. The toner goes down a tube, and goes into the sub hopper. The toner end sensor is attached to the sub hopper. Slide 185 This mechanism is the same for each of the four toner bottles in the machine.

Page 187: Toner Bottle
Di-C1.5 Training Toner Bottle Toner Bottle Development Unit Toner End Sensor TD Sensor When the toner bottle is installed, the bottle must be turned to the right (clockwise). This opens the bottle, and toner can leave the bottle. The spiral grooves in the bottle help to feed toner out of the rotating bottle.
Page 188: Toner Hopper Unit
Di-C1.5 Training Toner Hopper Unit Toner Hopper The toner hopper contains a small amount of carrier. This prevents large amounts of toner from entering the development unit during a long job with high image coverage. If a lot of toner is allowed to enter, toner scattering may occur.
Page 189 Di-C1.5 Training Radio Frequency ID Chip RFID Chip Antenna Board Each toner bottle has a chip. This chip contains data on the amount of toner consumed from the bottle, and is used for toner bottle detection (the machine uses it to detect if the bottle installed or not).
Page 190: Toner Near-End Detection
Di-C1.5 Training Toner Near-end Detection To detect toner near-end, the machine uses the following data: Toner supply motor rotation counter Pixel counter Toner end sensor If one (or both) of the counters detect that the remaining toner amount is less than a set value (see below), the machine enters the near-end condition.

Page 194: Toner End Recovery
Di-C1.5 Training Toner End Recovery The machine assumes that the toner cartridge was replaced if either of the following occurs when the near-end or end status exists: The front door is opened and closed. The main switch is turned off and on. Then the machine starts to supply toner to the development unit.

Di-C1.5 Training Skew Correction Skew Feed Motor Correction Sensor Skew Correction Roller First, the feed motor rotates forwards: The feed belt feeds the original, but the skew correction roller does not turn.

Page 313 Di-C1.5 Training Overview This unit adds an output tray. It does not replace the tray that is supplied with the machine. It is not a sorter, because the tray and/or the rollers do not move from side to side. With more than one output tray, the user can (for example) send copy-mode outputs to the standard output tray, and fax-mode outputs to the 1-bin tray.
Page 314 Di-C1.5 Training Components The main motor in the copier operates the tray. There is no motor in the tray. The junction gate solenoid in the paper exit mechanism of the main copier sends paper to this tray. The paper sensor in the one-bin tray checks if there is paper in the tray.
Page 315 Di-C1.5 Training LED on the One-bin Tray One-bin Tray This LED lights when the one-bin Standard tray has an Output Tray output in it This LED lights when an output arrives on the one-bin tray.

Page 317 Di-C1.5 Training Overview The side tray is an additional output tray. This can be installed when the 500-sheet finisher is installed, so that the user can (for example) send copy-mode outputs to the finisher tray, and fax-mode outputs to the side tray. This is because, when the finisher is installed, the one-bin tray cannot be installed.

Di-C1.5 Training Straight Feed-out Paper Feed Paths Inverter Junction Gate Stapling/Shift Sorting Inverter Path (Duplex Mode) There are three feed paths, as shown above. If duplex mode is selected, the paper is fed below the finisher, inverted, and fed back into the machine through the duplex unit.
Page 325 Di-C1.5 Training Pick-up Straight Feed-out Entrance Sensor Roller Unit Pick-up Roller When the entrance sensor detects the leading edge of the paper, the pick-up roller unit is lowered from its home position.
