Dot matrix printer toll free phone number ppt

Dot matrix printing or impact matrix printing is a type of computer printing which uses a print head that moves

back-and-forth, or in an up-and-down motion, on the page and prints by impact, striking an ink-soaked cloth

ribbon against the paper, much like the print mechanism on a typewriter. However, unlike a typewriter or daisy

wheel printer, letters are drawn out of a dot matrix, and thus, varied fonts and arbitrary graphics can be produced.

Each dot is produced by a tiny metal rod, also called a "wire" or "pin", which is driven forward by the power of a

tiny electromagnet or solenoid, either directly or through small levers (pawls). Facing the ribbon and the paper is a

small guide plate named ribbon mask holder or protector, sometimes also called butterfly for its typical shape. It is

pierced with holes to serve as guides for the pins. This plate may be made of hard plastic or an artificial jewel

such as sapphire or ruby.

The portion of the printer containing the pins is called the print head. When running the printer, it generally prints

one line of text at a time. There are two approaches to achieve this:Epson VP-500 Printer with its cover removed

This is an example of a wide-carriage printer, designed for paper 14 inches wide, shown with legal paper loaded

(8.5"×14"). Wide carriage printers were often used by businesses, to print accounting records on 11"×14" tractor-

feed paper. They were also called 132-column printers, though this description was only true for a specific font

size and type that was built into the printer's electronics.

The common serial dot matrix printers use a horizontally moving print head. The print head can be thought of

featuring a single vertical column of seven or more pins approximately the height of a character box. In reality, the

pins are arranged in up to four vertically or/and horizontally slightly displaced columns in order to increase the dot

density and print speed through interleaving without causing the pins to jam. Thereby, up to 48 pins can be used

to form the characters of a line while the print head moves horizontally.

In a considerably different configuration, so called line dot matrix printers use a fixed print head almost as wide as

the paper path utilizing a horizontal line of thousands of pins for printing. Sometimes two horizontally slightly

displaced rows are used to improve the effective dot density through interleaving. While still line-oriented, these

printers for the professional heavy-duty market effectively print a whole line at once while the paper moves

forward below the print head.

DOT MATRIX PRINTER HAVING PROBLEMS :

These days, you see fewer and fewer dot matrix printers in corporate environments. However, there

are situations where dot matrix printers are still essential, such as when printing on carbon copy

forms. Because dot matrix printers are so scarce these days, you've probably never touched one. But

someday, someone may ask you to fix one. Fortunately, these prehistoric beasts aren't that

complicated to figure out; although, it helps if you have an understanding of the most common dot

matrix printer problems and how to solve them. It's also good to have a few tricks up your sleeve for

finding replacement parts and/or printers.

Mystery paper jams

In my experience, the mystery paper jam, a jam with no obvious cause, is by far the most common dot

matrix problem. These jams are often caused by a small piece of paper lodged beneath the rollers or

beneath the tractor feed. While you can easily remove the rollers on most printers, it’s often easier to

go fishing with an unbent paper clip or similar extraction tool. You will often see this problem after the

printer has "eaten" a piece of paper. A large chunk of paper gets trapped under the rollers and then

gets bunched up by the printer’s motion, preventing other sheets from passing through the printer.

The problem can also occur if, when printing labels, a label separates from the backing and sticks to

the rollers.

White lines in printed text or graphics

Probably the second most common problem with dot matrix printers is the appearance of horizontal

white lines in the middle of printed text or graphics. This almost always signals a problem with the

print head. Usually, a pin in the print head has stopped working. I recommend making sure that the

print head data ribbon—not the ink ribbon—is connected tightly to the print head. If that checks out,

try cleaning the print head with alcohol. Sometimes residue can cause a pin to malfunction. If neither

of these tricks solves the problem, you will likely have to replace the print head.

Carriage movement but no printing

When a dot matrix printer's carriage moves and the printer makes noise but nothing is printed, it usually means

the ink ribbon is dried up or missing. If you know the ribbon is good, watch it while printing. The print head

should strike the ribbon as printing occurs. Furthermore, each time the print head returns, the printer should

advance the ink ribbon. If this isn’t happening, the ink ribbon may be installed incorrectly.

Printing gibberish

If the printer is printing gibberish, try printing some simple text. If you're able to print plain text but there’s a blank

line between each line of text, check the printer’s dip switch, which controls the carriage return and line feed

(CR/LF). By toggling this switch, you should be able to correct the problem.

If everything still comes out as gibberish, there are several possible causes—the most likely being an incorrect

print driver. For example, if someone tries to print to the printer using a print driver that was intended for a laser

printer, the job will print as gibberish. All future jobs will most likely print as gibberish until you have turned the

printer off and back on. A loose, faulty, or overly lengthy printer cable can also cause data to print gibberish. Try

switching to a known good printer cable and see if the problem goes away.

Flashing lights

Another problem that you may encounter is that the lights on the printer are flashing. You’ll have to check the

printer's instruction manual for this one. Different flashing patterns mean different things, and the meanings vary

among different makes and models of printers. Flashing lights could indicate anything from low ink to a paper

jam, to a cooked system board.

No activity at all

If you print to the printer and nothing happens at all, make sure the printer is receiving power and is connected

to the PC. If your users are on a network, you should also make sure the PC hasn’t been redirected to a network

printer. If nothing seems to work try running a self-test on the printer. If the self-test doesn’t yield any activity, it

could be that the motor has burned out or that the system board is fried.

Grinding noise

I’ve seen dot matrix printers make loud grinding noises during printing. More often than not the grinding noise

was caused by foreign matter jammed in the printer. Once this foreign matter was removed, the printer returned

to normal. However, I have also seen gears strip out on printers because they had worked their way out of

alignment. You might try turning off the printer and moving the carriage by hand to make sure everything moves

smoothly and that there is no resistance. You should also inspect the belts for excessive wear that would

indicate that they have stretched or are about to break.

Finding dot matrix printer parts

If your local computer store doesn’t even acknowledge that dot matrix printers still exist, what do you do when

you need a new ink ribbon or spare part for your printer? While searching the Internet may be the obvious

solution, I want to share some particularly effective strategies I've come across for handling dot matrix

availability problems.

Recycle old equipment

This first strategy was used by a tech friend of mine who works for a large organization. The company

purchased a sizable number of Epson LQ-1050 printers in the early 1990s. As laser printers became more

affordable, my friend began gradually replacing the dot matrix printers with networked laser printers. He

realized, however, that there were a few employees that would always need a dot matrix printer. To ensure that

he would always have replacement parts, he made a habit of taking every dot matrix printer that was phased

out and disassembling it. He then separated the various components and stored them in a several bins. One

bin was filled with motors, another with print heads, another with gears, and the list goes on. As time went on,

the company phased out well over 200 printers. Since there are only three people at the company who still use

the dot matrix printers, those people will have spare parts available for a long time to come. Look for

replacements in unconventional places Another unique strategy I discovered involved a small hospital I

supported several years ago. The hospital used dot matrix printers for patient billing. When an invoice was

printed, a copy was sent to the patient, another copy was sent to the insurance company, and yet another copy

was housed internally. The employee responsible for printing the invoices used an old Epson LQ-1170 printer.

One day, the printer died and could not be resurrected.

Common Dot Matrix Printer

problems and solutions

It helps if you have an understanding of the most common dot matrix printer problems and how to solve them.

under the rollers and then gets bunched up by the printer’s motion, preventing other sheets from passing through the

printer. The problem can also occur if, when printing labels, a label separates from the backing and sticks to the

rollers.

Mystery jams can also occur when the tractor feed edges separate from the page while printing. Sometimes this can

be a fluke, but other times it may point to a mechanical problem. Try taking the paper out of the printer and hitting the

form feed button a few times. Watch the printer’s tractor feeds to make sure they are moving and are in synch with

each other. Some printers use belts to move the tractor feeds and, over time, these belts wear, break, or become

misaligned.

White lines in printed text or graphics

Probably the second most common problem with dot matrix printers is the appearance of horizontal white lines in the

middle of printed text or graphics. This almost always signals a problem with the print head. Usually, a pin in the print

printer cable and see if the problem goes away. If way If these techniques fail to fix the problem, try generating a

print test directly from the printer (not from the computer). If the printer’s internal self-test also prints gibberish,

there’s a good chance that the printer’s system board is bad.

Flashing lights

Another problem that you may encounter is that the lights on the printer are flashing. You’ll have to check the
