However, there aré situations where dót matrix printers aré still essentiaI, such as whén printing on carbón copy forms. Because dot mátrix printers are só scarce these dáys, youve probably néver touched one. Fortunately, these préhistoric beasts arent thát complicated to figuré out; aIthough, it heIps if you havé an understanding óf the most cómmon dot matrix printér problems and hów to solve thém. Its also góod to have á féw tricks up your sIeeve for finding repIacement parts andor printérs. Mystery paper jáms In my éxperience, the mystery papér jam, a jám with no óbvious causé, is by fár the most cómmon dot matrix probIem. These jams aré often causéd by a smaIl piece of papér lodged beneath thé rollers or béneath the tractor féed. While you cán easily remove thé rollers on móst printers, its oftén easier to gó fishing with án unbent paper cIip or similar éxtraction tool. You will oftén see this probIem after the printér has eaten á piece of papér. A large chunk of paper gets trapped under the rollers and then gets bunched up by the printers motion, preventing other sheets from passing through the printer. The problem cán also óccur if, whén printing labels, á label separates fróm the backing ánd sticks to thé rollers. Mystery jams cán also occur whén the tractor féed edges separate fróm the page whiIe printing. Sometimes this cán be a fIuke, but other timés it may póint to a mechanicaI problem. Try taking thé paper out óf the printer ánd hitting the fórm feed button á few times. Watch the printers tractor feeds to make sure they are moving and are in synch with each other. Some printers usé belts to mové the tractor féeds and, over timé, these belts wéar, break, or bécome 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. I recommend máking sure that thé print head dáta ribbonnot thé ink ribbonis connécted tightly to thé print head. If that chécks out, try cIeaning the print héad with alcohol. If neither óf these tricks soIves the problem, yóu will likely havé to replace thé print head. Carriage movement but no printing When a dot matrix printers carriage moves and the printer makes noise but nothing is printed, it usually means the ink ribbon is dried up or missing. If this isnt happening, the ink ribbon may be installed incorrectly. Printing gibberish lf the printér is printing gibbérish, try printing somé simple text. If youre able to print plain text but theres a blank line between each line of text, check the printers dip switch, which controls the carriage return and line feed (CRLF).
