5028 Theory of operation Paper path and transport components For an image to be printed, the paper or specialty media has to be moved from an input source (such as a tray) into the printer and eventually exit into an output source. The most important component in this process is this paper itself.
Page 532
5028 MPF section The MPF has a sensor (MPF empty) which detects if paper is present. The motor (duplex/MPF) drives the MPF pick assembly. The pick assembly feeds the paper from the MPF tray into the printer through the sensor (MPF/pass‑through) and isolator nip at tray 1.
Page 533
5028 Isolation unit section The paper enters the isolation unit through one of two paths, each path having its own isolation roller. If the paper is fed from tray 1, the tray 1 isolation nip moves the paper through the isolation housing and into the aligner roller.
Page 534
5028 Description Alternate isolation roller Sensor (MPF/pass‑through) Aligner section After the paper reaches the sensor (input), or the sensor (MPF/pass‑through), a count is started. The paper is pushed up against the aligner rollers to align the leading edge of the paper and form a bubble. After a predetermined count from the sensor (input) is reached, the motor (aligner) turns and moves the paper through the aligner rollers and the sensor (input).
Page 535
5028 Description Transfer belt Sensor (input) Aligner roller Transfer roller Theory of operation...
Page 536
5028 Fuser section After the second transfer, the paper is fed to the fuser. The paper passes through the sensor (fuser buckle) located before the fuser. The sensor detects the buckle in the paper when it hits the fuser rollers. If the buckle is too great, the motor (fuser) speeds up to avoid causing a paper jam.
Page 537
5028 Description Decurl roller Fuser Sensor (fuser buckle) / Sensor (narrow media) Sensor (fuser exit) Sensor (paper exit) / Sensor (duplex entry) Duplex section After the first side of the paper is printed and the trailing edge of the paper clears the diverter, the diverter drops and the motor (output) engages in reverse.
Page 538
5028 After passing the sensor (duplex staging), the duplex aligner roller drives the paper to the isolation nip and to the sensor (MPF/pass‑through) where the leading-edge position of the paper is again updated. When the paper reaches the sensor (MPF/pass‑through) in the isolation unit, the paper is pushed to the deskew rollers. As the paper reaches the sensor (input) after the registration process, the motor (aligner) adjusts its speed to line up the leading edge exactly with the belt image at the second transfer.
Page 539
5028 Description Duplex feed roller Sensor (duplex staging) Duplex aligner roller Sensor (duplex entry) Print engine theory Electrophotographic process The method that all laser and LED printers use to print is called the electrophotographic (EP) process. These machines use differences in charge to manipulate and move toner from the print cartridge to the printed page. Even though the basic EP process is the same for every laser and LED printer, the specifics for each printer are different.
Page 540
5028 The transfer belt carries the four-colored image towards the transfer rolls. Paper is picked up from the tray and carried to the transfer roll where the image is transferred from the transfer belt to the paper. The timing of the paper pick is determined by the speed of the transfer belt.
Page 541
5028 The laser beam only discharges the surface where the beam hits the photoconductor. This creates a difference in charge potential between the exposed area and the rest of the photoconductor surface. Service tips • The laser beam passes through a glass lens as it exits the laser unit. If this lens gets contaminated with toner or other debris, vertical streaking of white/lightness on the page occurs.
Page 542
5028 This process is similar to using glue to write on a can and then rolling it over glitter. The glitter sticks to the glue but will not stick to the rest of the can. Service tips • Never touch the surface of the developer roller with your bare hand. The oil from your skin may cause a charge differential on the surface, and the toner will not stick properly.
Page 543
5028 The charge difference between the developed toner image on the photoconductor surface and the first transfer roller causes the images to transfer to the surface of the transfer module belt for each color. This takes place by a direct surface-to-surface contact between the photoconductors and the transfer module belt. Service tips •...
Page 544
5028 The HVPS sends voltage to the transfer roll to create a positive charge. When the image on the transfer belt reaches the transfer roll, the negatively charged toner clings to the paper and the entire image is transferred from the transfer belt to the paper. Service tips •...
Page 545
5028 The fuser applies heat and pressure to the page to melt the toner particles and bond them permanently to the paper. The fuser moves the paper to the redrive rolls which move the paper to the output bin. Service tips •...
Page 546
5028 After the toner is moved to the cleaning blade, the toner is moved to the waste toner area using an auger system. Photoconductor clean/erase After each plane of color has been transferred to the transfer belt from the photoconductors, a cleaning blade scrapes the remaining toner from the surface of each photoconductor.
Page 547
5028 Color theory Color theory What is RGB color? Red, green, and blue light can be added together in various amounts to produce a large range of colors observed in nature. For example, red and green can be combined to create yellow. Televisions and computer monitors create colors in this manner.
Page 548
5028 What is manual color correction? When manual color correction is enabled, the printer employs user-selected color conversion tables to process objects. However, Color Correction must be set to Manual, or no user-defined color conversion will be implemented. Manual color correction settings are specific to the type of object being printed (text, graphics, or images), and how the color of the object is specified in the software program (RGB or CMYK combinations).
Page 549
5028 By examining Color Samples sets, a user can identify the box whose color is the closest to the desired color. The color combination labelled on the box can then be used for modifying the color of the object in a software program.
