Ten Classic Printer Troubleshooting Methods - Printers, Office Equipment - Office Supplies Industry

Printer Has become almost essential for modern office supplies

, printing it to replace the traditional handwritten greatly enhance our work efficiency. Today, the type of printer is also uneven, ranging variety of printers, but the more high-tech products more susceptible to failure. No matter how advanced the printer again, the most important thing is printing, the printer must have a common fault. The following tips home to quote a few common printer problems and solutions, we want to help:

1, the printer outputs a blank paper

For stylus printer rise to printing paper blank, usually because the dry ink ribbon, ribbon pull off, the print head damage, etc., should be replaced or repaired the print head ribbon; for inkjet printers, printing blank cause The failure was largely due to nozzle clogging, ink cartridges do not Ink Etc., should be cleaned or replaced cartridge nozzle; while for laser printers, causing such failure may be due to roll is not bothered by the toner imaging (imaging roller DC bias is not added), it may be photosensitive drum is not grounded, so that Gravitropism negative charge can not release a laser beam can not play a role in the photosensitive drum.

In addition, the laser printer's imaging drum is not rotating, there will be no images generated and transmitted on paper. Disconnect the printer Power supply Remove the toner cartridge, open the lid on the notch, the photosensitive drum to be a sign of non-sensitive parts of re-loading machine. Switched on for a while, and then remove the check mark is moved, you can determine photosensitive drum is working. If the toner can not be normal supply or laser beam is blocked, there will be a blank paper to print the phenomenon. Therefore, we should check whether the run out of toner, ink cartridges into the machine is correct, whether the sealing tape were removed or whether the laser channel blocking properties. To note that the check be sure to turn off the power, because the laser beam may damage the operator's eyes.

2, black print on paper output

For dot matrix printer, causing the failure is due to Hair Removal ribbon, ribbon on too much ink, print head dirty, poor quality ribbon and putting too close to such position adjustment, repair should be the first regulation to promote pole position, such as the failure can not be excluded, and then replace the ribbon, cleaning print head, generally you can troubleshoot; for inkjet printers, should focus on checking whether the damaged nozzle, the ink tube is broken, the ink type is normal and so on; for laser printers , is mostly due to the corona discharge wire control circuit failure or malfunction, makes the laser has been fired, causing the output to print black. Therefore, we should check whether the corona discharge wire disconnected, or the existence of high-voltage corona, the laser beam path of the beam detector is working properly.

3, incomplete print character or characters is not clear

For inkjet printers, there may be two reasons, to make ink cartridges, printer, or direct sunlight for long time caused by blocked nozzles. The solution is to inject the ink cartridge or renewal, if the cartridge does not run out, it can be concluded that the nozzle plug: Remove the cartridge (not the one for the printer cartridge nozzle needs to remove the nozzle), the nozzle on the warm water soak for a while, Do not pay attention to certain parts of the circuit board immersed in water, or else.

For dot matrix printer, may have the following reasons: Print ribbon to use for too long; print head a long time without cleaning, too much dirt; print head with needle; print head drive circuitry is defective. The solution is to first adjust the print head and print about the spacing between rollers, failure can not be excluded, ribbon can be new ones, if still does not work, you need to clean the print head up. Methods are: removal of the print head, the two fixed screws, won the print head, a small hook with a needle or remove the print head before and after the inclusion of dirt, are generally long accumulation of ribbon fiber, and then in print visible needle back of the head where the oil a few drops of instruments to remove a number of dirty, has no space to play a few ribbons of paper, and then loaded ribbon, so that the basic problem can be solved, if the print head off needle or drive circuit problem, it can only replace the print pin or drive up again.
