5-2 Functional Information EN Printer Subsystems This chapter presents a generalized functional o v er view of the printer and the printing processes. Figure 5-1 P aper Feed Subsystem.
EN Power Supply System 5-3 P ower Suppl y System A C/DC P ower Distrib ution The A C line v oltage f or the printer is applied through the main switch (SW101) and supplied to the low-v oltage po wer supply circuit through the fuse (FU1). The low-v oltage power supply divides the A C v oltage to +24 VDC , +5 VDC and +3.
5-4 Functional Information EN Figure 5-2 Low V oltage P ower Supply Circuit If a shor t circuit or other problems on the load side cause an e xcessive current flo w from the +24 VDC or +3.
EN Power Supply System 5-5 Over current Overv oltage Pr otection This circuit located on the DC controller PCA alwa ys monitors an abnormal r ise of the fusing roller temperature. If an error occurs , this circuit outputs a signal to turn the rela y (RL1) off and interrupt the powe r to the fusing roller heater .
5-6 Functional Information EN High V oltage P ower Distribution Figure 5-3 High V oltage P ow er Supply Circuit In response to the instructions from the microprocessor (CPU: IC301) on the DC controlle.
EN Power Supply System 5-7 T oner Car t ridge Detection The T oner Car tridge has a toner sensor . The circuit compares the output value of the de veloping A C bias and the output value (ANT) from the antenna inside the car tr idge, and outputs the toner detection signal.
5-8 Functional Information EN Figure 5-4 DC Controller PCA Laser and Scanner Drive Based on inf ormation received from the F ormatter , the DC Controller Board sends signals to the Laser/Scanner Assembly to modulate the laser diode on and off and to drive the Laser/Scanner motor .
EN Power Supply System 5-9 P aper Motion Monitoring and Control The DC Controller Board controls paper motion by contin uously monitoring the various paper sensors, and coordinating paper mov ement with the other print processes. F or more inf or mation, see “P aper Feed System” on page 5-29.
5-10 Functional Information EN Motors See “Timing Diagram” on page 5-47 f or specific timing details for the printer motors. The Main Motor , MT1, is controlled by the DC Controller Board.
EN Power Supply System 5-11 The Scanner Motor is controlled and monitored by the DC Controller Board. It rotates the scanner mirror during the Initial Rotation per iod and the print per iod. The f an motor is a two-phase, f our-pole DC br ushless motor containing a hall element and f orms a unit along with the motor dr ive circuit.
5-12 Functional Information EN Formatter System The F ormatter PCA is responsible f or the f ollowing: ● Controlling the P owerSa v e mode. ● Receiving and processing print data from the various printer interf aces.
EN Formatter System 5-13 The printer exits P owe rSav e mode and enters the war m up cycle when any of the f ollowing occurs: ● A print job , v alid data, or a PML or PJL command is receiv ed at the parallel por t or an EIO card. ● A Control P anel key is pressed.
5-14 Functional Information EN Input/Output P arallel Interface The F ormatter PCA receives incoming data through its bidirectional interf ace (IEEE 1284). The I/O provides high speed and tw o wa y communication between the printer and the host, allowing the user to change printer settings and monitor pr inter status from the host computer .
EN Formatter System 5-15 Printer Memory Note If the printer encounters difficulty managing av ailable memory , a clearab le warning message will be displa yed on the Control P anel. Some printer messages are affected b y the A uto Continue and Clearab le W ar ning settings from the Configuration Menu in the printer’ s Control P anel.
5-16 Functional Information EN DIMM Slots The DIMM slots ma y be used to add memor y , f onts, or firmware upgrades . Note that DIMMs and SIMMS are not compatib le. There are two types of DIMMs suppor ted: EDO DIMMs are 32-bit, 100-pin, 60nsec. SDRAM DIMMs are 32-bit, 100-pin, 66MHz.
EN Formatter System 5-17 PJL Overview Printer Job Language (PJL) is an integral par t of configuration, in addition to the standard Printer Command Language (PCL). With standard cabling, PJL allo ws the printer to perform functions such as: ● T wo-wa y communication with the host computer through a Bidirectional P arallel connection.
5-18 Functional Information EN Image Formation System The image f ormation system is the main par t of the printer , and consists of six stages: When the F ormatter Board sends the pr int signal to th.
EN Image Formation System 5-19 Figure 5-6 Image F ormation System After the image has been transf erred to the paper , it is then fused onto the paper by heat and pressure at the Fuser .
5-20 Functional Information EN T oner Car t ridge A major por tion of the Image Formation system is contained in the car tr idge as shown in the figure below . The T oner Car tridge is the “hear t” of the Image Fo r mation System. It houses the cleaning, conditioning, and de v eloping steps of the process.
EN Image Formation System 5-21 Photosensitive Drum The special proper ties of the photosensitive drum allow an image to be f ormed on the dr um surface and then tr ansf erred to paper . The drum is an aluminum cylinder . The outside of the cylinder is coated with a la yer of organic-photoconductiv e mater ial (OPC) which is non- to xic.
5-22 Functional Information EN Cleaning the Drum In the transf er stage, not all the toner is transf erred to the paper , but some remains on the photosensitive drum. In this stage, the residual toner is cleaned so that the ne xt print image will be clear and distinct.
EN Image Formation System 5-23 Conditioning the Drum After the drum is cleaned, it must be conditioned. This process consists of applying a unif orm negative charge on the surf ace of the drum with the pr imar y charging roller .
5-24 Functional Information EN Writing the Image During the wr iting process, a modulated laser diode projects the beam onto the rotating six-sided scanning mirror . As the mirror rotates, the beam reflects off the mirror , through a set of f ocusing lenses, through a slot in the rear of the T oner Car tr idge, and onto the photosensitiv e drum.
EN Image Formation System 5-25 Developing the Ima ge The de v eloping process de velops the latent electrostatic image into a visible image on the drum. The de veloping unit consists of a metallic cylinder that rotates around a fix ed magnetic core inside the toner cavity .
5-26 Functional Information EN T ransferring the Image During the transferring process the toner image on the drum surface is transf erred to the paper . A positiv e charge applied to the back of the paper by the tr ansf er roller causes the negativ ely charged toner on the drum surface to be attr acted to the page.
EN Image Formation System 5-27 Image Fusing/V ariable Fusing T emperature During the fusing process, the toner is fused into the paper by heat and pressure to produce a permanent image. The paper passes between a heated fusing roller and a soft pressure roller .
