A____________ is type of electrophotographic printer that uses a laser beam to control how toner is placed on the page and then uses heat to fuse the toner to the page. Provide high-quality resolution. | Laser printer |
A laser printer work by placing toner on | an electrically charged rotating drum (sometimes called the image drum) and then Toner deposited on paper moving at drum speed. |
The six steps that a laser printer performs to print are cleaning, conditioning, writing, developing, transferring, and fusing. | These stages (except for transferring) take place inside removable cartridges, which makes the printer easier to maintain. |
Drum cleaned of residual toner and charge | Cleaning |
Drum surface charged to -600 V | Conditioning |
Laser beam writes -100 V image to drum surface | Writing |
Toner applied to -100 V areas of the drum | Developing |
Toner drawn off drum and onto paper | Transferring |
Heat and pressure fuse toner to paper | Fusing |
First four laser printing steps undergo the most wear, to make the printer last longer, these steps are done | inside removable cartridge that can be replaced and Reduce costs by performing steps in removable cartridges. |
For older laser printers, all four steps were done | inside one cartridge |
For newer laser prnters, cleaning, conditioning, and writing stages are done | inside the image drum cartridge. |
By using these multiple cartridges inside a laser printers, | the cost of maintaining a laser printer is reduced. |
The writing process on a color laser printing repeated four times, | one for each toner color of cyan, magenta, yellow, and black. |
A__________Use a type of ink-dispersion printing, Give photo-quality result, especially when used with photo-quality paper, and Are popular because they are small and can print color inexpensively. They are slower than laser printers. | inkjet printer |
Inkjet printers print by | shooting ionized ink at a sheet of paper. Print head moves across paper, creating one line of the image with each pass. Ink applied to paper using matrix of small dots. |
The most popular inkjet printer is Bubble-jet printers use | tubes of ink that have tiny resistors near the end of each tube. |
A type of ink dispersion printer that uses cartridges of ink. The ink is heated to a boiling point and then ejected onto the paper through tiny nozzles. | inkjet printer |
Inkjet printer have: | Lower resolution. Images smudge on inexpensive paper. Usually cost less. |
Dot matrix printers are a type of impact printer. | They print by projecting pins from the print head against an inked ribbon that deposits ink on the paper. |
An_________printer creates a printed page by using some mechanism that touches or hits the paper. | impact printer |
Overheating can damage a print head of a dot matrix printer, so | Keep the printer in a cool, well-ventilated area and Do not print over 50 to 75 pages without a cool down so that it will last longer. |
Dot matrix printer technology advantages: | Continuous tractor feed allows event and data logging. Can use carbon paper: print multiple copies. Extremely durable. |
A________uses waxbased ink, which is heated by heat pins that melt the ink onto paper and use heat to produce output. | thermal printer |
Two similar technologies are thermal printers and solide ink printers. Both use | heat to produce printed output. |
Thermal printers are popular in retail application for | printing reciepts, bar codes, and price tags. |
One variation of thermal printing uses___________to print identification cards and acces cards and uses solid dyes embedded on different transparent films. | dye-sublimation technology |
A________uses sticks or blocks of solid ink. The ink is melted and then jetted onto the paper as the paper passes by on a drum. | solid ink printer |
Printer Features, including | Extra paper trays, special paper feeders or transparency feeders, staplers, collators, sorters and,Duplexing |
The technology the printer uses to format a page before it is printed: | PCL, PostScript, GDL, OR XPS. In addition, printers can receive raw data that can be printed with no processing. |
A local printer can connect directly to a computer by way of a | Bluetooth, infrared, or Wi-Fi, IEEE 1394 (FireWire) port, SCSI port, PC Card, or ExpressCard connection.etc... |
A network printer has an ethernet port to connect directly to the network . this connection can be made to a | switch, hub, router port, or Wi-Fi |
A network printers are usually identified on the network by their | IP address |
The last step to install a printer is to print a | printer test page. |
The Windows print spool is managed from the | Vista Printers window or the XP Printers and Faxes window |
Printer consumables include paper, ink ribbons, ink cartridges, toner cartridges, image drum cartridge, fuser cartridge, and transfer belt. | Keep consumables on hand so they will be available before they are needed |
Memory and a hard drive can be added to a printer to | improve performance and prevent errors |
The nozzles of an inkjet printer tend to clog or dry out, especially when the printer remains unused. The nozzles can be cleaned automatically by means of | printer software or buttons on the front panel of the printer. |
Printer firmware can be upgraded to | solve printing errors. |
Use the printer Properties box | to manage a printer. |
To share an installed local or network printer using Vista, | Printer sharing must be turned on in the Network and Sharing Center |
To share an installed printer using XP, | File and Printer Sharing must be installed |
To use a shared printer on a remote PC, | Client for Microsoft Networks must be installed. |
You can install a shared printer on a remote computer using one of two methodes: | (1)Use the Vista Printer window or the XP Printers and Faxes window.(2)Use the Network or My Network Places window. |
Placing print jobs in a print queue so that an application can be released from the printing process before printing is completed.___________ is an acronym for simultaneous peripheral operations online | Spooling |
A queue for print jobs is called | print spool |
If you are having a problem with a printer refusing to print or you cannot use certain features, | printer drivers might be incompatble or out of date. |
Clean the inside of the printer with a dry cloth Toner-certified vacuum cleaner, and | Extension magnet brush. Do not blow out toner with compressed air |
Manufacturers of high-end printers provide __________,which include specific printer components, After you have performed the maintenance, be sure to reset the page count so it will be accurate to tell you when you need to do the next routine maintenance. | printer maintenance kits |
If a self-test page works and you have already stepped through checking the printer connectivity, but you still cannot print a test page from Windows. The print spool might be stalled. | Try deleting all print jobs in the printer’s queue. You can also power cycle the printer (turn it off and back on). |
If the printer self-test worked, but the OS printer test did not work. | check for connectivity problems between the printer and the PC. For a local printer connected directly to a PC, the problem might be with the printer cable or the port the printer is using. |
If the self-test page prints but the OS test page does not print and the printer is a network printer or shared printer, | the problem might be with connectivity between the PC and the network printer or with the host computer that is sharing the printer. |
When a network printer is shared by a computer, the printer appears in the | Network or My Network Places windows of other computers on the network |
Poor print quality, including faded, smeared, wavy, speckled, or streaked printouts, often indicates that the toner is low. The solution to poor-quality printing is to replace this | cartridge |
IF THE PRINTER STAYS IN WARM-UP MODE, | It should turn off as soon as the printer establishes communication with the PC |
If paper is jammed inside the printer OR PAPER OUT MESSAGE APPEARS | follow the directions in the printer documentation to remove the paper. Don’t jerk the paper from the printer mechanism, but pull evenly on the paper, with care. Damp paper can cause paper jams. Be sure to only use dry paper in a printer. |
IF ONE OR MORE WHITE STREAKS APPEAR IN THE PRINT, | Remove the toner cartridge, shake it from side to side to redistribute the toner supply. Streaking is usually caused by a dirty developer unit or corona wire. |
IF THE PRINT APPEARS SPECKLED, | Try replacing the cartridge. If the problem persists, the power supply assembly might be damaged. Replace the laser drum. |
If loose toner comes out with your printout, | The fuser is not reaching the proper temperature. Professional service is required. |
If printed images are distorted and there is no paper jam, foreign material inside the printer might be interfering with the mechanical components. | Check for debris that might be interfering with the printer operation. If the page has a gray background or gray print, the image drum is worn out and needs to be replaced. |
A_____________images are usually caused by a problem with the image drum or toner cartridge. The drum is not fully cleaned in the cleaning stage, and toner left on it causes the ____________images. | Ghosted |
A____________ when symbols or other special characters don’t print correctly, try using binary (bitmap) printing rather than asking the printer to interpret the characters. To make the change when printing a document, open the printer Properties box. | GARBAGE PRINTOUTS |
IF THE PRINTER MAKES A STRANGE NOISE | The printer might not be sitting level or stable. Check inside the printer for jammed paper or loose or broken parts. The cover or paper trays on the printer might not be fully closed. |
If a high-end printer has a control panel on the front, it might display an error message or error code. Most likely the code will not explain the problem. | search the printer documentation or Web site to find out the meaning of the code. |
A PORTION OF THE PAGE DOES NOT PRINT | the printer does not have enough memory to hold the entire page |
PRINT QUALITY IS POOR with Inkjet Printers | Reinstall cartridge, check ink, clean nozzles. The better the quality of the paper used with an inkjet printer, the better the print quality. Do not use less than 20-LB paper in any type of printer. |
Printing is intermittent or absent with Inkjet Printers | Verify driver, ink supply, nozzles, cartridges |
Lines or dots are missing from the printed page OR Ink streaks appear on the printed page with Inkjet Printers | Clean the inkjet nozzles |
Print quality is poor ORPrint head moves back and forth but nothing prints with Impact Printers | Check ribbon advancement. Adjust the print head spacing. Check the print head for dirt |
