80Laser beam pathThe scan line is written on the drum from the front end towards the rear of the machine.Collimating lensLD unitNo additional notes.
81Colour skew adjustment The adjusters must be used after installing a new LD unit. There is one for each color.They move the front of the F-theta lens-2 from left to right, seen from the front of the machine.This moves the position of the scan line on the drum, to correct for colour skew.F-theta lens-2Turning the adjuster clockwise moves the front of the scan line to the left, which corrects skew where the left side of the image is lower than the right side.Adjusters
82After replacing a laser unit There are two things to do:Initialize the D-phase data and shading data.See the service manual (Replacement and Adjustment, Laser Optics).Do the color skew adjustment procedure.Explained on the next few slides.No additional notes.
83Colour skew adjustment (1/5) Execute ‘MUSIC’ (SP ).After you execute MUSIC, check the adjustment with the following SPs.(Black)(Cyan)(Magenta)(Yellow)No skew adjustment is required when all SP values are within ±5.When one or more of the SP values is not within ±5, then you must adjust colour skew for any color that has an SP value that is not 0.For example:If is -4, and the others are +1, no adjustment is necessary.If is -6, and the others are +1, the adjustment must be done for all four colours.If is -6, and the others are 0, the adjustment must be done only for magenta.No additional notes.
84Colour skew adjustment (2/5) Open the front cover [A].Remove the upper cover [B]. Then close the front cover again.Execute ‘MUSIC’ (SP ) again.This is because removing the upper cover may have caused the LD units to slip out of alignment.No additional notes.
85Colour skew adjustment (3/5) Adjust the colours that need correction using the knobs shown below.See the procedure in the service manual for details.These adjustments move the L2 F-theta lenses-2 inside the laser units.No additional notes.
86Colour skew adjustment (4/5) This shows one of the four knobs.Rotate each knob corresponding to the value shown in SP to 004.Clockwise: 90 degrees corresponds to changing the SP value by “+1”Counterclockwise: 90 degrees corresponds to changing the SP value by “-1“A click is felt every 90 degree rotation of the knob.Examples:If the SP value is +6, turn knob [A] in the diagram 6 clicks clockwise.If the SP value is -7, turn knob [A] 7 clicks counterclockwise.No additional notes.
87Colour skew adjustment (5/5) Reassemble the machine.Execute ‘MUSIC’ (SP )Check the SPs (SP to 004). If one or more of them is over ±5 (either positive or negative), repeat the adjustment.The adjustment is finished when all SP values are ±5.No additional notes.Before adjustmentAfter adjustment

1166.9 Waste toner collection No additional notes.
117Overview The waste toner drops at the front of the bottle. A coil moves the waste toner from the ITB unit, the Y PCDU and M PCDU towards the left-side of the bottle.The agitator makes the surface of the toner level.There is another agitator for toner that arrives from the ITB (see the next slide).Waste toner from the C and K drums drops straight into the bottle.No additional notes.
118MechanismWhen the coil rotates, the agitators move the toner towards the rear of the bottle.The bottle full sensor detects when the bottle is almost full, and the machine displays a warning on the screen.After near-full is detected, the machine calculates when the bottle becomes full, and stops operating.No additional notes.
119Replacing the waste toner bottle Move the 5 caps [A] from their storage location on the waste toner bottle to the inlets, so no toner will spill out when you transport the bottle.Dispose of used bottles in accordance with local regulations.These caps are included with every waste toner bottle.
121PrincipleThis machine uses a Quick Start Up Direct Heating (QSU-DH) fusing system which saves energy and improves print quality.The new fusing unit uses a thin fusing belt which turns freely around the lamp.No heating roller or hot roller.The fusing belt is much thinner than a hot roller, so less electricity is used to reach the fusing temperature.By using a flat fusing pad, fusing is done on a flat surface without uneven pressure from the pressure roller.This means that there is less damage/wrinkling to the paper.This is especially helpful for envelope printing.No additional notes.
123Free-belt fusing system Sleeve beltFusing padMirrorFusing lampPressure rollerThe sleeve belt rotates freely.It is driven by the pressure roller.The fusing pad has a low friction surface, this allows the sleeve belt to turn easily.The pressure roller presses against the pad to form the nip zone.The stay holds the pad in place.The stay has a mirrored surface facing the fusing lamp.This to concentrate the energy from the lamps to the left side of the inner surface of the sleeve belt.The temperature at the ends of the lamp is lower than at the center.The reflector plate prevents heat from the fusing lamp from damaging other machine components.There is no lamp in the pressure roller.Diana-C1.5 series: There is a steel pipe inside the belt.Griffin-C1: No steel pipe. More energy is conserved.Reflector plateStay
124Temperature control components Sleeve belt thermistorSleeve belt thermopileThermostatFusing lampThe fusing temperature is monitored by thermistors and thermostats.The thermostat is also a safety switch to prevent overheating.The thermopile is attached to the main body of the machine.It is not part of the fusing unit.The fuse for new fusing unit detection only exists in service parts.It does not exist in the fusing unit that is built into the machine at the factory.The fuse is only used to reset SC554.(see later this presentation)It does NOT reset any counters.Why are there two pressure roller thermistors?One of them is just outside the paper width of A4/LT, and the other is just inside. They monitor the roller temperature within the paper feed area and outside this area (where the temperature will be higher).Pressure rollerthermistorsFuse for new unit detection

126Fusing unit replacement After the fusing unit is replaced you must do the following:Set SP to “1”.Exit the SP-mode.Switch the machine off and on.Check SP whether the fusing is reset correctly.The fuse for new unit detection does NOT reset SP
127Fusing sleeve belt replacement The fusing pad must face the pressure roller.The fusing sleeve belt is replaced as an assembly.No additional notes.
128SC 554If SC occurs, there could be temperature damage to the fusing unit.The fusing unit should be replaced, but if it is not damaged, you can continue to use it.In the field service manual there is a separate procedure for SCNo additional notes.
129SP 5-810From the flow chart on the previous slide, you can see that a new SP (SP ) is added.If you do this SP, the machine checks for the fuse for new unit detection, and blows the fuse if it is found.If the fuse is not found and blown, the SP execution fails.SP is normally only done as part of the countermeasure for SC 554.SP does not look for or try to blow the fuse.
130Fuse for new unit detection The fuse is shown below [A].It is not included in machines shipped from the factory.The fuse is present in fusing units that are installed as service parts, but it is blown immediately after the fusing unit is installed.So, in each case, if you will re-use a fusing unit that has encountered SC554 but is not damaged, you need to get a new fuse and install it like shown below.
