Page 21 IMPORTANT SAFETY NOTICES PREVENTION OF PHYSICAL INJURY 1. Be sure that the power cord is unplugged before disassembling or assembling parts of the copier or peripherals. 2. The wall outlet should be near the copier and easily accessible. 3. Note that electrical voltage is supplied to some components of the copier and the paper tray unit even while the main power switch is off.
Page 22 LASER SAFETY The Center for Devices and Radiological Health (CDRH) prohibits the repair of laser-based optical units in the field. The optical housing unit can only be repaired in a factory or at a location with the requisite equipment. The laser subsystem is replaceable in the field by a qualified Customer Engineer.

Page 172 DRUM CHARGE How Correction is Made Immediately after creating the ID sensor pattern [A] used for toner density control (☛ 6.12.4), the machine generates another pattern [B] for charge voltage correction by intensifying the development bias (☛ 6.12.2) to –600 V. The laser remains off, but a small amount of toner moves to the drum because of the slight charge difference between the drum and development roller.
Page 173 DRUM CHARGE 6.11.4 DETECTION OF A NEW PCU Before starting to use a new PCU, the machine must (a) agitate the toner/developer mix, (b) initialize the TD sensor, and (c) initialize the PCU counter. This machine automatically detects the presence of a new PCU and carries out these operations.
Page 174 DEVELOPMENT 6.12 DEVELOPMENT 6.12.1 OVERVIEW B046D563.WMF The development section consists of the following parts. 1. Development Roller 4. TD Sensor 2. ID Sensor 5. Mixing Auger 1 3. Mixing Auger 2 6. Doctor Blade The two mixing augers mix the developer (carrier/toner mix). The TD (toner density) sensor and the ID (image density) sensor are used to control the copy image density.
Page 175 DEVELOPMENT 6.12.2 DEVELOPMENT BIAS B046D309.WMF Black areas of the latent image on the drum are at low negative charge (about -140 ± 50 V), with white areas at high negative charge (about –900 V). To attract negatively charged toner to black areas, the high voltage supply board [A] applies a (default) bias of –600 V to the development roller [B].
Page 176 DEVELOPMENT 6.12.3 TONER SUPPLY Toner-Bottle Models (B044 and B046) B046D306.WMF B046D307.WMF When toner bottle [A] is pushed in, shutter [B] is pushed open by the PCU body. Pressing in lever [C] pulls off toner bottle cap [D], which is held by chuck [E]. When clutch [F] turns the bottle, the spiral grooves push toner out at [G], and the turning Mylar blades [H] push this toner through slit [I] into the developing unit.
Page 177 DEVELOPMENT Toner Hopper Magazine (B045) The magazine houses a grooved bottle similar to that shown on page 6-34 (except that it has no cap). The shuttering and rotation mechanisms are the same as on toner-bottle models (as seen on page 6-34). B046D308.WMF B046D310.WMF 6-35...
Page 178 DEVELOPMENT 6.12.4 TONER DENSITY CONTROL Overview Toner concentration in the developer is controlled using the following values: • Vts: TD sensor initial setting (1.25V). (Used as reference voltage when Vref is not available.) • Vref: Toner supply reference voltage (calculated value; periodically updated) •...
Page 179 DEVELOPMENT Toner Concentration Measurement The machines checks concentration every copy cycle, by comparing Vt against the reference voltage. Vsp/Vsg Detection An ID sensor pattern is made on the drum by the charge roller and laser diode. The ID sensor detects the pattern density (Vsp) and the density of the bare drum (Vsg).
Page 180 DEVELOPMENT 6.12.5 TONER SUPPLY IF SENSOR READING IS ABNORMAL ID Sensor Any of the following is considered abnormal: • Vsg ≤ 1.65 (when Vsg is read) • Vsg < 2.31 (at maximum power) • Vsp ≥ 1.65 • Vt ≥ 2.64 or Vt < 0.20 Current readings can be viewed using SP2-221.

Page 186 IMAGE TRANSFER AND PAPER SEPARATION 6.15 IMAGE TRANSFER AND PAPER SEPARATION 6.15.1 OVERVIEW B046D401.WMF B046D572.WMF B046D302.WMF The transfer roller [A] is pressed against the OPC drum [B]. The high-voltage power supply board [C] supplies a positive current to the transfer roller, attracting the toner from the drum onto the paper.
Page 187 IMAGE TRANSFER AND PAPER SEPARATION 6.15.2 IMAGE TRANSFER CURRENT TIMING There are two current levels used during the transfer sequence: low and high. 1. At time of write-start signal, the high voltage supply board generates low current (5 A) to the roller. This prevents positive toner on the drum from moving to the roller.
Page 188 IMAGE TRANSFER AND PAPER SEPARATION 6.15.3 TRANSFER ROLLER CLEANING Toner may transfer to the roller surface following a paper jam or if the paper is smaller than the image. Periodic cleaning of the roller is required to prevent this toner from migrating back to the rear of new printouts. The machine cleans the roller at the following times: •...

CONTROLLER FUNCTIONS 4.2 CONTROLLER FUNCTIONS 4.2.1 PAPER SOURCE SELECTION Tray Priority (Auto Tray Select) Start of Tray Search Tray 1 Tray 2 B441D510.WMF The controller searches for the specified paper size, starting from Tray 1, and uses the first tray that has the specified paper size. If the selected tray is pulled out or runs out of paper during printing, the controller searches for another tray with the specific paper size and if found, automatically switches to it.
Page 377: Tray Lock
CONTROLLER FUNCTIONS Tray Lock If Tray Lock is enabled for a tray, the controller does not use the “locked” tray in the tray search process. If a tray has, for example, colored A4 size paper for fax prints, enable tray lock for that tray so that the controller does not select the tray for printing.
