Image-formation process The imag e-for mat ion system consists of ten s teps div id ed in to si x fun cti ona l blo ck s. Figure 1-12 Image-form ati on pr oc ess : Step : Block : Direction of drum rotation : Media path ITB cleaning 9. ITB cleaning Developing 4.
Step 1: P re-ex posur e Ligh t from the p re-exposure LE D strike s the surface of th e photosensi tive drum to remo ve any resi dual electr ical ch arges from the dr um surfac e.
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 iv e char ge neutr ali ze s in tho se ar eas , whic h ar e then read y to accept tone r.
Step 5: Primary tra nsfer The posi tiv el y charg ed prima ry-trans fer roll er s co ntac t the ITB, giving the ITB a positi ve char ge . The ITB attra cts the nega tively charg ed tone r fro m the su rfa ce of each photosens it iv e dru m, an d the comple te toner ima ge tra ns fer s onto t he ITB.
Step 7: S eparati on 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 i ng 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 ton er col lecti 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 lop ing-rol ler enga gem ent and disengagem en t cont ro l operat es as foll ows : Wh en the product 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 tosens iti ve dr ums .
Primary-tr a nsf er-r oller 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-r ol ler di sen gagement c am .

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 strati on c ontr ol corre cts the fo ll owi ng pr ob .
Environm ent al changes or deter iorat ion of the photosen si tiv e drums and toner can cause v ari ati ons in the im age dens ity. The i mage-stabi lization c ontrol red uces these fluctuat ions.
