High-voltage power supply The DC controller controls the high-v oltage pow er supply to genera te biases. The high- voltage pow er supply delivers the high-v oltage bias es to the following c omponent.
Circuit Description Primary-transfer-bias generation The primary transfer bias transfers th e toner from each photosensit ive drum onto the ITB. The primary transfer bias circuit in the high-v oltage power supply generates the biases f or each color.
Low-voltage power supply The low-v oltage power- supply circui t convert s the AC power from the wall receptacl e into the DC voltag e that the p roduct comp onents use. T he product h as two low -voltage powe r-supplies f or 110 Vo lt or 220 Volt in put.

Image-form ation system The i mage-format ion system c reates the p rinted imag e on the p aper. The system co nsists of the followi ng compon ents: ● Print ca rtri dges ● ITB ● Secon dary tran .

Image-formation process The imag e-formation system consists of ten steps div ided into six fun ctional blo cks. Figure 1-12 Image-form ation process : Step : Block : Direction of drum rotation : Media path ITB cleaning 9. ITB cleaning Developing 4. Developing 5.
Step 1: P re-ex posur e Ligh t fro m the pre-expo sure LED stri kes the surf ace of the photose nsitive drum to remove any re sidual electr ical charges from the drum surface.
Step 3: Laser -beam e xposur e The l aser beam strikes th e surface of the phot osensitive drum in th e areas whe re the im age will fo rm. The negat ive charge neutr alizes in those ar eas, which are then read y to accept tone r.
Step 5: Primary tra nsfer The posi tively charged prima ry-trans fer rollers contac t the ITB, giving the IT B a positive charge . The ITB attra cts the negatively cha rged toner from the su rface of each photos ensitive dru m, and the comple te toner ima ge transfers onto the ITB.
Step 7: Separa tion The s tiffness of the paper c auses it to separate from the ITB as the ITB bends. The s tatic-char ge elimin ator remov es excess charge from the paper t o make sur e that the toner fus es correctl y.
Step 9: ITB clean ing The c leaning bla de scrapes the resid ual toner o ff the surfac e of the ITB. The residu al toner f eed scre w deposit s residual toner in the toner collecti on box.
The DC controller r otates the d rum motor to drive the photose nsitive dr um, deve loping rol ler, and th e prim ary- charg ing roll er. Figure 1-23 Pri nt-cart ridge sys tem Primary charging roller .
The DC controller determine s a memory tag error a nd notifie s the forma tter when it fails to ei ther read from or write to the memory ta g. ● Cartridg e presence detection: T he DC co ntroller detec ts the pr esence of the cartri dges by monitori ng the mem ory tag.
The deve loping-r oller engagem ent and diseng agement cont rol operat es as follows: Wh en the produc t is turn ed on and whe n each print job i s completed, al l four of the devel oping units are disengaged fro m the pho tosensitive dr ums. ● The drive of the de veloping di sengagem ent motor r otates the developin g disengag ement ca m.
Primary-tr ansfer-roller e ngage ment and disengagement The s equence of t he prim ary-transfer-rol ler engage ment and disengag ement contr ol is as follows: 1. The fuse r motor tur ns on the primary- transfer d isengagement solenoid and rotates the prim ary- transf er-roller di sengageme nt cam.
Figure 1-26 Three states of pr imary-trans fer-roller eng agement and di sengageme nt M2 SL1 IT B DC controller Fuser motor Primary transfer disengagement solenoid SR9: Primary transfer disengagement .
ITB cleaning The c leaning blade in t he ITB clea ner scrape s the resi dual toner off the ITB surface . The re sidual toner feed sc rew deposi ts the resi dual tone r to the residual to ner feed unit. The ITB motor and the residu al toner feed m otor drive the screw.
Color-misregistration control Interna l variation s in the lase r/scanne rs can cause the toner ima ges to become misaligne d. The col or- misregi stration control corrects the followi ng problems: .
Environm ental change s or deteriorat ion of the photosensi tive drums and toner can cause variati ons in the im age dens ity. The i mage-stabi lization c ontrol red uces these fluctuat ions.
Pickup, fee d, and delivery s ystem The pi ckup, feed, and deli very system uses a se ries of r ollers to m ove the pape r through the pro duct. Figure 1-29 Paper path Duplex model only Duplex media p.
