Ten common printer troubleshooting methods:
1, the printer output of blank paper
For stylus printer, causing a blank paper, usually because the dry ink ribbon color
With a pull-off, the print head is damaged and so on, shall promptly replace or repair ribbon print head; for inkjet printers,
Most of the failures caused by printing a blank is due to nozzle clogging, there is no ink cartridges, etc. should be cleaned nozzles, or
Replacement cartridges; while for laser printers, causing such failures may be due to imaging is not sucked ink roller
Powder (Developing roller DC bias is not added), it may be photosensitive drum is not grounded, so that the negative charge can not be gravitropism
Release, the laser beam can not play a role in the photosensitive drum.
In addition, the laser printer drum does not rotate, no images will be generated and transmitted on paper. Off
Open the printer power supply, remove the toner cartridges, open the lid on the notch, in the photosensitive drum to do the non-photosensitive area
A token re-load machines. Switched on for a while, and then remove the check mark is moved, that is,
Determine whether the photosensitive drum are working properly. If you can not normally supply of toner or laser beam is blocked, will be
Print blank sheets of paper the phenomenon occurs. Therefore, should check whether the run out of toner, ink cartridges loaded machine is correct
, The sealing tape has been Qudiao or laser irradiation channels have obscured objects. Important to note that
, Be sure to check the power off, because the laser beam may damage the operator's eyes.
2, printing paper output black
For stylus printer, causing the failure because the ribbon hair removal, the ink ribbon too much, playing
Print head dirty, poor quality, and putting ribbons location so close to such adjustment, repair should be putting the first position adjustment
, Such as the failure can not be excluded, and then replace the ribbons, cleaning print head, the general failure can be ruled out; for the spray
Ink printer, should focus on checking whether the nozzle is damaged, the ink tube is broken, the ink model whether it is
Chang, etc.; for laser printers, while mostly due to corona discharge wire control circuit failure or failure of
Makes laser has been fired, causing the contents of all Printing Spare Parts black printout. Therefore, should check the corona wire is
Has been disconnected or the existence of high-voltage corona discharge, the laser beam path of the beam detector is working properly.
3, print incomplete character or characters is not clear
For inkjet printers, there may be two reasons, to make ink cartridges, printer, or a long time without
By the nozzle clogging caused by direct sunlight. Solution can be new ones or inject ink cartridge, if the cartridge
Not used up, it can be concluded that the nozzle plug: Remove the cartridge (not the one for the printer cartridge nozzle
The need to remove the nozzle), soak the nozzle in warm water for a while, pay attention to the circuit board must not be
Some submerged in water, otherwise the consequences would be unthinkable.
For stylus printer, you may have the following reasons: Print ribbon use of time too long; to play
Print head a long time without cleaning, dirt too much; print head has Broken Needle; print head drive circuit is faulty.
The solution is the first print head and print some adjustment of the spacing between rollers, fault can not be excluded, you can new ones
Ribbon, if still does not work, you need to clean the print head of the. Methods are: shirk the print head of the two solid
Set 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 a long ribbon fiber, and then see the back of the print head where a few drops of needle instrument oil
To remove some stains, has no space to play a few ribbons of paper, then fitted a HeidelBerg Parts, so that the basic problem can be
To resolve, if the print head Broken Needle or the driver circuit problem, we can only replace the print pin or drive tube
