1, print characters or lack of incomplete, and the character was not clear.
Analysis: For inkjet printers, there may be two reasons: 1. Ink cartridges do; 2. Printers do not have a long time or subject to direct sunlight, nozzle clogging. For stylus printer may be the following reasons: 1. Printed ribbon used for too long; 2. Print head a long time without cleaning, dirt too much; 3. Print head has Broken Needle; 4. Print head drive circuit is faulty.
Solution: For inkjet printers, or inject ink cartridges can be new ones, if the cartridge is not exhausted, it can be concluded that the nozzle plug: Remove the cartridge (for the non-integrated ink jet printer, need to remove the nozzle, but carefully), the nozzle in warm water soak for a while, pay attention to certain parts of circuit board not to dip in water, or else. For stylus printer, you can adjust print head and look at the spacing between the printing rollers, if not, could be new ones ribbon, if still does not work, you need to clean the print head. Methods are: shirk the print head 2 fixed screws, won the print head, with a needle or small hooks clear the print head before and after the inclusion of the stains, are generally accumulated over a long ribbon fiber, and then in print visible needle back of the head where a few drops of instrument oil, to remove some stains, has no space to play a few ribbons of paper, then fitted a ribbon, so that basic problem can be solved, if it is the print head off pin or a driver circuit problem, it will only get the maintenance department went.
Second, the paper print when you print an article appear uneven thickness of the black war are serious entire paper.
Analysis: This phenomenon usually appears in the stylus printer, the reason is too dirty, or the print head print head and printing roller spacing is too small or too thick printing paper cause.
Solution: remove the print head, cleared of what the print head, or some adjustment between the print head and printing roller spacing.
Third, when you print writing side of a clear, while the other side was not clear.
Analysis: This phenomenon is generally appear on the stylus printer, inkjet printer may also appear, but the probability of a smaller, mainly print head guide and print roller is not parallel, resulting in far distance between the two nearly due.
Solution: You can adjust print head rail and printing roller spacing, so that parallel. Specific methods are: the respective rail on both sides of the print head screw loose regulation films, anti-clockwise rotation adjustment pieces to make space smaller, clockwise can increase the gap and finally the print head rail and print roller can be adjusted parallel to solve the problem. Should pay attention to conditioned tone right direction, you can gradually adjust, multi-printed several times.
4, print, print head when you feel affected by the resistance will stop printing an issue of ringing or vibration in situ.
Analysis: print head rail sliding long time will become dry, the print head moves will be blocked, to a certain level will cause the printer to stop, seriously burned when you can drive circuit.
Solution: a few drops in print rail Tu instrument oil, moving the print head back and forth to make it uniform. To re-boot, if there are blocked and, that may be burned driver circuit needs to get the maintenance department of the.
5, the printer after boot no response, simply does not power.
Cause analysis; printers have over-current protection device, when the current is too large, when it will play the role of current protection. This phenomenon is basically the printer fuse burned out.
Solutions; open the chassis, internal power supply part of the printer to find the insurance tube (internal power supply part of the printer can be found in the vicinity of the external power supply), to see if black, or multimeter measurements to see if they burn, if the burn, for a basic in line fuse can be the (insurance tubes are marked with the rated current).
