- 22Inkjet Printer Process14 step process that gets the process of printing a page going
- 23Inkjet Printer Process 1You click the print button that initiates the printing process
- 24Inkjet Printer Process 2The software from which you are printing sends the data to be printed to the printer driver that you have selected
- 25Inkjet Printer Process 3The printer driver uses a page description language to convert the data being printed into the format that the printer can understand. The driver also ensures that the printer is ready to print
- 26Inkjet Printer Process 4The printe driver sends the information to he printer via whatever connection method is being used
- 27Inkjet Printer Process 5The printer stores the recieved data in its onboard print buffer memory
- 28Inkjet Printer Process 6If the pritner has not printed in a while the printer control circuit activate a cleaning cycle
- 29Inkjet Printer Process 7Once the pritner is ready to print, the control circuirty activates the paper feed motor
- 30Inkjet Printer Process 8Once the paper is positioned properly the print head stepper motor use the print head belt and carriage to move the print head across the page little by little
- 31Inkjet Printer Process 9The motor is moved one small step and the print head sprays the dots of ink on the paper in the patterns dicated by the control circuitry
- 32Inkjet Printer Process 10Then the stepper moto moves the print head another small step the process repeats all the way across the page
- 33Inkjet Printer Process 11At the end of a pass across the page the paper feed stepper motor advances the page a small amount then repeats step 8
- 34Inkjet Printer Process 12Depending on the model either the print head returns to the beginning of the line and prints again in the same direction or it moves backward across the page so that printing occurs in both direction. Continues until page is finished
- 35Inkjet Printer Process 13Once the page is finished the feed stepper moto is actuated and ejects the page from the printer into the output tray
- 36Inkjet Printer Process 14Once printing is complete and the final page is ejected from the printer, the print head is parked ((locked into rest position)
- 37Printer Buffersmall amount of memory (512 MB to 16 MB) used to store print jobs as they recieved from the printing computer
- 38Cleaning Cyclea set of steps the inket printer geos trhough to purge the print heads of any dried ink
- 39Laser PrinterTwo types of Electrophotographic (EP) imaging process and LEDS to create the image on the drum
- 40Toner CartridgeApart of a laser printer. The toner is a black carbob substance mixed with polyester resin to make it flow better and iron oxide particles to make it sensitive to electrical charges. They contain a medium call developer that carries the toner until it used by the EP process. Contains the EP Printer Drum
- 41EP Print DrumApart of the toner cartridge, the drum is coated with a photosensitive material that can hold a static charge when not expossed to light but cannot hold a charge when it is exposed to light. Contains a cleaning blade that continously scrapes the used toner off the photosensitive drum to keep it clean
- 42Laser Scanning Assemblythat shines on a particular area of the EP drum contains the lasesr assembly, laser beam and rotating mirror
- 43High-Voltage Power Supplyin laser printers it converts AC current from a standard wall outlet into higher voltages that the printer can use
- 44DC Power Supplyin laser priner current components can't use high voltages, and needs lower voltages that the DC power supply can use, usually between +5VDC and +24VDC. The DCPS converts into +5VDC and -5VDC for the logic circuitry and +24VDC for the paper transport motors
- 45Transfer Corona Assemblyis apart of the laser printer it transferred a high voltage charge to the apper which pulls the toner from the photosensitive drum. Also contains a static charge eliminator. There are two types of corona assemblies a transfer corona wire and transfer corona roller
- 46Static charge eliminator stripthat drains away the charge imparted to the paer by the corona
- 47Transfer corona wireapart of a transfer Corona assembly a small wire that is located in a special notch in the floor of the laser printer, lower speeds
- 48Transfer corona rollerapart of a transfer corona ssembly a roller that directly contacts the paper and supports higher speeds and is the preferred assembly
- 49Fusing Assemblyapart of a laser printer uses two rollers that apply pressure and head to fuse the plastic toner particles to the paper
- 50Printer Controller Circuitryapart of the laser printer the large circuit board converts ignals from he computer into signals for the various assemblies the printer using a proccess known as rasterizing
- 51Ozone Filterapart of the laser printer it is a filter that takes care of the ozone chemicals that build up because of the high-voltage. the filter must be removed and cleaned.
- 52Electrophotographic Imaging Process (7 step process)Processing, Charging, Exposing, Developing, Transferring, Fusing, cleaning.
- 53EP Imagining Process Step 1recieves the image and creates teh image and then the printer needs to create the print job in such a way that it can accurately produce the output
- 54Raster Image Processor (RIP)manaages raster creation, responsibility is to generate an image of the final page in memory
- 55EP Imagining Process Step 2The corona wire or roller in the EP toner cartridge gets high voltage from HVPS and applies a uniform negative charge around (-600VDC) to the surface of the drum
- 56EP Imagining Process Step 3Exposing step is when the laser is urned on and scans teh drum from side to side, flashing on and off according to the bits of info that the printer controller sends it as it communicztes the individual bits of the image
- 57EP Imagining Process Step 4Developing step is when the surface of the drum holds an electrical representation of the imaege being printered. the chargges need to be converted into something that can be transferred to a piece of paper. The developing roller gets the same charge as the roller and repelsl the unexposed areas
- 58EP Imagining Process Step 5The transfering step the developed image is rotating into position. The controller notifies the registration rollers taht the paper should be feed through
- 59EP Imagining Process Step 6The fusing step is when the paper gets pushed through and fuses to the paper because it melts the polyester resin of the toner and rubberized pressure roller presses it permanently into the paper
- 60EP Imagining Process Step 7The Cleaning step is when the rubber blade inside the ep cartrdige scrapes any toner left on the drum into a used toner receptacle inside the EP cartridge
- 61Thermal Printersusually used in POS terminals. It uses heat sensitive paper that turns blacked when heat is applied to it. Some use a heat sensitive ribbon instead of a heat sensitive paper.
- 62Thermal transfer printeruses a heat sensitive ribbon that melts wax based ink from the ribbon to the printer
- 633D Printerscreates 3D objects by fabrication products by printing thin layers of a material and stacking those layers on top of each other, differemt types but popular ones use filaments or Resin
- 643D Filament PrinterContains frame, printing plate, extruder, cooling fan, pcb circuit board, the frame holds together, the printing plate will keep the object on the print plate by heating it, the extruder heats up and melts the plastic filament. cooling fans keep everything cool, circuit board is underneath the machine and control it.
- 65Filament Typespopular tupes are polyactic acid (PLA) and acrylonitrile butadiene styrene (ABS).
- 66Serial Printer Interface Typesold-time serial (DB-9) connections, are slow af, while things like thunderbolt, eSATA and other make it a more viable option, but USB is most common type of connector
- 67Parrallel Printer Interface Typethe parrallel port will recieve data 8 bits at a time over 8 seperate wires. They are quite rare as most wired printers will use Ethernet or USB
- 68ethernet Interface Typethese printers will have a NIC and ROM-based software. THEY WILL USE A RJ-45 CONNECTOR
- 69Installing and Sharing Local PrintersChoose the proper setup location for the device, attach the device using a local port and connect the power, install and update the device driver and calibrate he device, configure option and settings, print a test page, Verify compatibility with the poerating system and applications, educate users about basic functionality
