1. When printing at a very low dpi, the printer can't increase the dot size pitch (how large an individual dot is) to compensate for a low number of resolution lines in the print. Increase the print resolution setting. 2. Clean the print heads and rollers. 3. Gently shake the cartridge to see if you can get more ink/toner out of it. Replace the cartridge.
1. How do you perform a halfway test on a laser printer? 2. What does this test verify?
1. print a page and open the toner lid when you believe the paper is underneath the toner cartridge. This stops the printing so you can pull the toner cartridge out and look at the partially printed paper. 2. If you do not see the print issue on your test page, that means the problem is caused by the fuser later in the printing process. If you see the print issue on your test page, that means the problem is occurring before the fuser. Try replacing the toner cartridge.
If there are vertical lines on a printed page, how would you rule out the following issues? 1. Toner on the main corona or transfer corona wire 2. Low resolution image
1.Can cause vertical white areas on a laser printout. Clean the corona wires or replace the toner cartridge, which has new corona wires in it. 2. Lower resolution images that display okay on screen might be stretched out when printed. This increases the likelihood of the small spaces between image pixels being visible, which can lead to vertical lines running down the paper. Obtain a higher resolution image.

What are the two ways in which paper may be fed though an impact printer?
Friction feed: A series of plastic or rubber rollers move a sheet of paper through the printer. Friction feed doesn't require special paper, and is the same method used by most inkjet and laser printers. Tractor feed: Two sprocket wheels are mounted on either side of the printer. Tractor feed paper has perforated holes on each side which fit over the sprockets so that they can feed it through the printer. Most tractor feed paper has perforations at the side so that you can remove the feed holes after printing.
What can you do to loosen articulate inside a printer before vacuuming?
Gently dust the interior with a dry, soft, paintbrush
How is impact paper different from regular printer paper?
Impact printers typically use continuous form paper arranged into a roll or folded stack. It might have perforations at standard intervals which allow you to separate the paper into individual sheets, or the printer might have an edge that you use to tear the paper into individual sheets along a straight edge.
What parts may need to be replaced on Inkjet printers over time?
Inkjet nozzles become clogged due to ink buildup, causing inconstant output and blank areas. If software or physical cleaning doesn't fix the problem, you might be able to replace the head. Some inkjets have print heads built into the cartridge which is replaced whenever you replace the cartridge.
How do inkjet printers work?
Inkjet printers use ink-dispersion and wet ink to transfer an image onto paper.
What parts may need to be replaced on laser printers over time?
Laser printers have a lot of moving parts which are prone to wear and failure. When the printer hits its preset maintenance interval, you can install replacement parts from a manufacturer maintenance kit. A typical maintenance kit might include a fuser assembly, transfer roller, pickup rollers, separation pads, corona assembly, and fan assembly. Some kits come with cleaning cloths and gloves.
How do laser printers work?
Laser printers use focused light, electrical charges, and a dry powder ink (called toner) to transfer an image using to paper. The photosensitive drum, rubber cleaning blade, toner, and developing roller are all contained within a replaceable laser printer cartridge.
What are a inkjet printer's usual quality settings?
Normal: 300 × 300 or 320 × 320 dpi High quality: 600 × 600 or 720 × 720 dpi Photo quality: 1200 × 1200, 1440 × 1440 dpi, 2880 × 1440 and up .... dpi= dots per inch

Operating system updates can sometimes negatively affect printer drivers. => If you are running Windows, run the Printer Troubleshooter, or if your manufacturer provides one, run their Print Diagnostic Utility. => Download and reinstall the print driver. => Remove and reinstall the printer. => Use a system restore to roll your system back to a time when you could connect.
How would you describe the mechanism of a line impact printer?
Prints an entire line at once, allowing faster output. Depending on the type, an impact line printer might use a wide comb to produce dot matrix output, or it might have character glyphs arranged on a drum, chain, or bar.
How would you describe the mechanism of a dot matrix impact printer?
Prints one character at a time using a print head made up of small pins. The pins are individually struck against the ribbon to create a pattern of dots which can form characters or pictures. Dot matrix printing is faster and more flexible than daisy wheel printing, but it produces lower quality text. Print heads typically have between 9 and 24 pins. Higher pin counts create sharper output.
How would you describe Solid Ink Thermal Printing?
Solid ink printer, which uses solid blocks of waxy pigment which are melted and dispersed onto the paper in a method very similar to inkjet printing. Solid ink printers are typically used much like inkjet or laser printers; unlike inkjets they don't wet the paper and won't streak due to moisture.
Where are the items being printed by a 3D printer usually modeled?
The 3D printing process begins with a file created in a 3D modeling program, such as AutoCAD, Blender, or even Paint 3D included with Windows 10.
What is the second place to check when troubleshooting printer issues?
The OS event log
What is duplexing assembly?
The duplexing assembly automatically reverses a piece of paper after the first side has been printed, allowing the printer to print on both sides of a single sheet of paper. Duplex print devices offer a variety of print format options including: Single-sided page to single-sided page (1:1) Double-sided page to double-sided page (2:2) Single-sided page to double-sided page (1:2) Double-sided booklet formats (2:2 with a center fold)
What is usually included with a laser printers replacement toner cartridge?
The electrostatically charged toner, and the photosensitive drum
1. What is the Inkjet printing process?
The printer's motor assembly moves the print head across the paper from left to right and back again, printing a strip of the image in small dots with each pass. When a strip is complete, the paper feed stepper motor moves the paper advance rollers, which draws the paper into position for printing the next strip.
IF you want to connect to a printer over a network, what do you information do you need to make the connection?
The printers IP address or host name.
What parts may need to be replaced on Thermal and Impact printers over time?
Thermal and impact print heads face the most mechanical stress, and wear can cause quality degradation even after a ribbon replacement. To replace the head, look for a lever or button that pops the print head out. Position the new print head in place and snap it into place.
How would you describe direct thermal printing?
Thermal printing requires heat-sensitive paper. The paper is moved by a feeder roller to the print head. The print head applies heat to the paper to form letters and images. Direct thermal printing requires the print head elements to be in direct contact with the thermal paper as it is pulled across the print head. The overall effect is very much like dot matrix printing, but it's quicker and quieter. While it requires special paper, it doesn't need a print ribbon.
How would you describe Thermal Transfer Printing?
Thermal transfer printing, uses ribbon printer cartridges containing waxy ink. The print head heats the ink on the ribbon and transfers it to the paper. Unlike direct thermal printing, it doesn't need special paper.
