Which document exhibits better quality, one printed with 600 dpi or one printed with
1200 dpi? Why? |

| During the laser printing process, what determines when the toner sticks to the drum and when it does not stick to the drum? |
|
Definition
| During the laser printing process, a magnet inside the cylinder is what determines when the toner sticks to the drum and when it does not stick to the drum. It makes the toner stick to the drum where the laser beam has hit and is repelled from the area where the laser beam has not hit |

Why is it less expensive to maintain an inkjet printer that has a black ink cartridge than

| How can you prove a printer problem is not with the printer itself, but lies with the network, computer, OS, or application? |
|
Definition
| It depends on printer. For laser printers it's very easy to do, just print out test page using controls located on the printer itself. With other printer is harder because of absence of testing interface. The only choice you have is to connect the printer to computer try to get it printing. If does on one computer and does not do it somewhere else you point is proved. |

| How do Graphics Device Interfaces work? |
|
Definition
| GDI draws and formats the page and then sends the almost-ready- to-print page to the printer in bitmap form. Because Windows, rather than the printer, does most of the work of building the page, a GDI printer needs less firmware and memory, and, therefore, generally costs less than a PCL or PostScript printer. |

| What are the six steps of laser printing? |
|
Definition
1. Cleaning. A sweeper strip cleans the drum of any residual toner, which is swept away by a sweeping blade. Erase lamps light the surface of the drum to neutralize any elec- trical charge left on it. These erase lamps are usually in the top cover of the printer.
2. Conditioning. The drum is conditioned by a roller that places a high uniform electri- cal charge of –600V on the surface of the drum. The roller is called the primary charging roller or primary corona, which is charged by a high-voltage power supply assembly.
3. Writing. A laser beam discharges a lower charge only to places where toner should go. The uniform charge applied in Step 2 is discharged only where you want the printer to print. This is done by controlling motors and mirrors that direct the laser beam to scan across the drum until it completes the correct number of passes for each inch of the drum circumference. For example, for a 1200 dots per inch (dpi) printer, the beam makes 1200 passes for every one inch of the drum circumference. The laser beam is turned on and off continually as it makes a single pass down the length of the drum, so that dots are written along the drum on every pass. For a 1200-dpi printer, 1200 dots are written along the drum for every inch of linear pass. The 1200 dots per inch down this single pass, com- bined with 1200 passes per inch of drum circumference, accomplish the resolution of 1200 x 1200 dots per square inch of many desktop laser printers. The laser beam has written an image to the drum surface as a –100V charge. The –100V charge on this image area will be used in the developing stage to transmit toner to the drum surface.
4. Developing. The developing cylinder applies toner to the surface of the drum. The toner is charged and sticks to the developing cylinder because of a magnet inside the cylinder. A control blade prevents too much toner from sticking to the cylinder surface. As the cylinder rotates very close to the drum, the toner is attracted to the part of the surface of the drum that has a –100V charge and repelled from the –600V part of the drum surface. The result is that toner sticks to the drum where the laser beam has hit and is repelled from the area where the laser beam has not hit.
5. Transferring. In the transferring step (shown in Figure 22-2), a strong electrical charge draws the toner off the drum onto the paper. This is the first step that takes place outside the cartridge and the first step that involves the paper. The transfer charging roller puts a positive charge on the paper to pull the toner from the drum onto the paper. Then the static charge eliminator (refer again to Figure 22-2) weakens the charges on both the paper and the drum so that the paper does not stick to the drum. The stiffness of the paper and the small radius of the drum also help the paper move away from the drum and toward the fusing assembly. Very thin paper can wrap around the drum, which is why printer manuals usually instruct you to use only paper designated for laser printers.
6. Fusing. The fusing step uses heat and pressure to fuse the toner to the paper. Up to this point, the toner is merely sitting on the paper. The fusing rollers apply heat to the paper, which causes the toner to melt, and the rollers apply pressure to bond the melted toner into the paper. The temperature of the rollers is monitored by the printer. If the temperature exceeds an allowed maximum value (410 degrees F for some printers), the printer shuts down.
7. Paper train. Timing. How long it takes for the paper to come out. Output process. |
