A good user manual
The rules should oblige the seller to give the purchaser an operating instrucion of HP C4077-90960, along with an item. The lack of an instruction or false information given to customer shall constitute grounds to apply for a complaint because of nonconformity of goods with the contract. In accordance with the law, a customer can receive an instruction in non-paper form; lately graphic and electronic forms of the manuals, as well as instructional videos have been majorly used. A necessary precondition for this is the unmistakable, legible character of an instruction.
What is an instruction?
The term originates from the Latin word „instructio”, which means organizing. Therefore, in an instruction of HP C4077-90960 one could find a process description. An instruction's purpose is to teach, to ease the start-up and an item's use or performance of certain activities. An instruction is a compilation of information about an item/a service, it is a clue.
Unfortunately, only a few customers devote their time to read an instruction of HP C4077-90960. A good user manual introduces us to a number of additional functionalities of the purchased item, and also helps us to avoid the formation of most of the defects.
What should a perfect user manual contain?
First and foremost, an user manual of HP C4077-90960 should contain:
- informations concerning technical data of HP C4077-90960
- name of the manufacturer and a year of construction of the HP C4077-90960 item
- rules of operation, control and maintenance of the HP C4077-90960 item
- safety signs and mark certificates which confirm compatibility with appropriate standards
Why don't we read the manuals?
Usually it results from the lack of time and certainty about functionalities of purchased items. Unfortunately, networking and start-up of HP C4077-90960 alone are not enough. An instruction contains a number of clues concerning respective functionalities, safety rules, maintenance methods (what means should be used), eventual defects of HP C4077-90960, and methods of problem resolution. Eventually, when one still can't find the answer to his problems, he will be directed to the HP service. Lately animated manuals and instructional videos are quite popular among customers. These kinds of user manuals are effective; they assure that a customer will familiarize himself with the whole material, and won't skip complicated, technical information of HP C4077-90960.
Why one should read the manuals?
It is mostly in the manuals where we will find the details concerning construction and possibility of the HP C4077-90960 item, and its use of respective accessory, as well as information concerning all the functions and facilities.
After a successful purchase of an item one should find a moment and get to know with every part of an instruction. Currently the manuals are carefully prearranged and translated, so they could be fully understood by its users. The manuals will serve as an informational aid.

Power Distribution System The AC and DC power supply circuits are contained in the Low Voltage Power Supply (LVPS). The high voltages required for image formation ar e generated by the High Voltage Power Supply (HVPS). The Low Voltage Power Supply and Distribution System is illustrated in Figure 5-2. Refer to the Reference Diagrams at the end of Ch[...]

Page 91
AC Power Distribution The AC power circuitry supplies AC voltage whenever the power cord is connected, and the power switch is ON. A toner cartridge must be installed and the top access door must be closed before AC voltage is supplied to the DC power circuits or the Fusing Assembly. Overcurrent/Overvoltage Protection There are two overcurr ent/ove[...]

High V oltage Power Distribution The High Voltage Power Supply (HVPS, see Figure 5-4) applies a DC biased AC voltage to the primary charging roller and the developing roller, and a programmed DC voltage (depending upon the phase of the printing proc ess) to the Transfer Roller. Refer to the General Timing Diagram (Figur e 5-22) at the end of this c[...]

Image Formation System Laser printing requires the interaction of several different technologies (such as electronics, optics, and electrophotographics) to provide a printed page. Each process functions independently and must be coordinated with the other printer processes. The image formation process consists of six steps: 1 Drum Cleaning 2 Drum C[...]
-
Page 98
T oner Cartridge The toner cartridge is the “heart” of the Image Formation System. It houses the cleaning, conditioning, and developing steps of the process. The toner cartridge contains the photosensitive drum, pr imary charging roller, developing station, toner cavity, and cleaning station. Including the components that wear, degrade, or are [...]

Page 99
Drum Cleaning The cleaning blade inside the toner cartridge is in contact with the surface of the drum at all times. As the drum rotates during printing, excess toner is removed from the drum surface and stor ed in the waste toner receptacle inside the toner cartridge. Drum Cleaning Figure 5-8 5-14 Functional Overview[...]

Page 100
Drum Conditioning After the drum is physically cleaned, it is conditioned by applying a uniform negative charge across the surface of the drum with the pr imary charging roller, located in the toner cartridge. The primary char ging roller is coated with conductive rubber, charged with an AC curr ent which erases any residual charges, and produc es [...]

Image W riting During the writing process, a modulated laser diode projects a beam onto a rotating six-sided scanning mirror. As the scanning mir ror rotates, the beam is directed through a set of focusing lens es to a direction changing mirror which reflects it through a slot on the top of the toner cartr idge, and onto the photosensitive drum.

Image Developing The developing process changes the latent electrostatic image into a visible image by depositing negatively charged toner particles on the exposed ar eas of the drum. The developing station is located inside the toner cartridge and consists of a metallic cylinder that rotates around a fixed magnetic core. The developing cylinder is[...]

Page 103
Image T ransferring and Media Separation During the image transferring process, the toner image on the drum surface is transferred to the media. A positive char ge applied to the back of the media by the transfer roller, causes the negatively char ged toner particles on the drum surface to be attracted to the media. The small diameter of the drum, [...]

Page 104
Image Fusing The Fusing Assembly bonds the toner particles into the media with a heated fusing roller and a soft pressure roller. Ther e are two levers on the Fusing Assembly which adjust roller pressure for single sheets (down position), or envelopes (up position). Both levers must be set to the same position. The fusing roller contains two quartz[...]
