No.1, the printer outputs a blank paper
The stylus printer, causing paper blank, usually because the ribbon ink dried, pull off the ribbon, print head damage, etc., should be replaced or repaired the print head ribbon; for inkjet printers, mostly caused by the failure to print a blank is due to nozzle clogging, no ink cartridges, etc., should be cleaned or replacement cartridge nozzle; and for laser printers, causing such failures may be due to the developer roller is not bothered by the toner (developer roller DC bias is not added), but also may be the drum is not grounded, so that the release of negative charge can not gravitropism, the laser beam can not drum on the work.
In addition, the laser printer drum does not rotate, no image will be generated and transmitted on paper. Disconnect the printer power supply, remove the toner cartridge, open the lid of the notch, in the non-photosensitive drum parts to be re-marked into the machine. Switched on for a while, and then remove the check mark whether the move, you can determine the drum is working properly. If the normal supply of toner or laser beam can not be blocked, there will be the phenomenon of printing blank paper. Therefore, you should check whether the run out of toner, ink cartridges into the machine correctly, whether the sealing tape were removed or whether the laser irradiation channel blocking properties. Note that, check to be sure Dell latitude d600 battery power is off, because the laser beam may damage the operator’s eyes.
No.2, the output of black paper
For the dot matrix printer, causing the failure is due to Hair ribbon, ribbon ink too, the print head dirty, poor quality and putting the ribbon location so close to such adjustment, repair should be the first adjustment fader position If the problem can not be excluded, and then replace the ribbon, cleaning print head, generally can troubleshoot; for inkjet printers, should focus on checking whether the damage to the nozzle, the ink tube is broken, the ink type is normal and so on; for laser printers, for the most wire due to corona discharge control circuit failure or malfunction, so the laser has been fired, causing the output to print black. Therefore, you should check whether the corona discharge wire has been disconnected or the existence of high-voltage corona, the laser beam path of the beam detector is working properly.
No.3, incomplete or characters printed characters are not clear
For inkjet printers, there may be two reasons, to make ink cartridges, printer or direct sunlight for a long time without resulting nozzle clogged. The solution is for renewal of ink cartridge or injection, 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, need to remove the nozzle), the nozzle in warm water soak for a while, Note that some of the circuit board must not be immersed in water, or else.
For the dot matrix printer, there may be several reasons: The print ribbon with long time; print head for a long time without cleaning, too much dirt; print head has broken needles; print head drive circuit failure. The solution is to adjust the print head and print about the spacing between rolls, failure can not be ruled out, the ribbon can be renewed, if not enough, we need to clean the Dell latitude d830 battery print head. Is: Remove the two screws on the print head, won the print head, or a small hook with a needle to clear the print head before and after the inclusion of the dirt, the accumulation of the ribbons are generally long fiber, and then in print see the back of the head where a few drops of instrumentation needle oil, in order to remove some dirt, do not install a few dozen empty ribbon of paper, then fitted the ribbon, so that the basic problem can be solved, if it is off the print head needle or drive circuit problem, it can only replace the print pin or driver in charge of.
No.4, print handwriting underweight
For the dot matrix printer, causing most of the causes of such ribbon ink dried, printhead needle, putting position modulation too far, you can adjust the putter with the replacement of the ribbon and the methods to solve; for inkjet printers, clogs, ink had dried, the ink type is not correct, enter the ink tube into the air, the printer operating temperature is too high will cause the failure to deal with the nozzle, the ink cartridges for detection and maintenance; for laser printers, the toner when the toner box small, low voltage developing roller and toner photographic developing poor results, it will also result in the phenomenon of print handwriting subdued. At this point, remove the toner cartridge gently shaken, if not improved print quality, replace or adjust the printer toner cartridge toner cartridge under a light-sensitive switch, so that the photographic sensitivity of matching with the toner.
No.5, while writing a clear and print the other side is not clear
This Dell inspiron 2500 battery phenomenon usually appears in the dot matrix printer, the inkjet printer may also appear, but the probability of small, mainly the print head and print roller is not parallel to the rail, resulting in two nearly caused a far distance. The solution is to adjust the print head and print roller rail spacing, making it parallel. Specifically: rails, respectively, on both sides of loosening regulation of the print head chip, reducing the gap counterclockwise rotation flap, and finally to the print head and print roller guide can be adjusted to solve problems in parallel. Note, however, conditioned on the direction of transfer can be gradually adjusted, multi-print several times.
No.6, the print paper repeated smears
Dirty stylus printer repeated failures are mostly due to too much ink ribbon caused by hair removal or replacement ribbon cartridge can be ruled out; repeated dirty inkjet printer ink cartridge, or lost due to leak ink due to ink tube; poor performance when the nozzle when the ink ejected ink can not very well off and remaining in balance while also Loumo phenomenon; the laser printer has a certain regularity of these phenomena, as a piece of paper through the printer , 12 inside the roll more than turned around, the biggest drum circle 2 or 3 turn, feed roller may be turned 10 laps, when the paper appears stains equal intervals, may be caused by dirty or caused damage to the roll.
No.7, the print head moves blocked, stop sounding or vibrating in place
This was mainly due to a long rail slide the print head can become dry, the print head will move blocked, to a certain extent will make printing stop, if not treated seriously burned when driving circuit. The solution is coated with a few drops on the print guide instrument oil, the print head moves back and forth to make it evenly distributed. After a reboot, if there is disruption phenomenon, the drive circuit may be burnt out, need to get a maintenance department.
No.8, the printer does not print
Failure caused by the printer does not print a variety of reasons, a printer’s, but also in computers. The following are the description:
1. Check whether the Dell inspiron 9400 battery printer is online. In most of the printer “OnLine” button next to them indicates online status lights, under normal circumstances the light should be in line Always state. If the indicator is not lit or is flashing, then the line is not normal, key check printer is turned on, the printer power switch is turned on, the printer cable is connected correctly and so on. If the online light properly, turn off the printer, and then open, print a test page to see whether it is normal.
2. Check whether the printer has been set as the default printer. Click the “Start / Settings / Printer”, check the current use of the printer icon on whether there is a small black hook, and then set the printer as the default printer. If the “Printers” window does not use the printer, then click the “Add Printer” icon, then follow the prompts to install.
3. Check the current printer is set to pause printing. Is in the “Printers” window by right-clicking the printer icon, the drop-down menu that appears check the “Pause Printing” option if there is a small hook, if you select the “Pause Printing” Please cancel the option.
4. In the “notebook” in the casual type some text, then click “File” menu “Print.” If you can print the test document, then there are problems with the printing process, focus on examination of WPS, CCED, Word or other applications the correct printer is selected, if the application generates a print file, please check the printout generated by the application is correct.
5. Check the computer’s hard disk space is too small. If less than 10MB hard disk space available, you can not print, check is in the “My Computer” using right-click the hard disk to install Windows icon, select “Properties” in the “General” tab, check the hard disk space, if hard disk space less than 10MB, you must empty the “Recycle Bin”, delete temporary files on the hard disk, expired or no longer used files to free up more space.
6. Check the printer driver is appropriate, and print the configuration is correct. In the “Printer Properties” window in the “Details” option in the check the following: In the “Print to the following port” select box, check the printer port settings are correct, the most commonly used port is “LPT1 (printer port),” but Some printers are required to use other ports; If you can not print large files, you should focus on examination of “time-out settings” section of the “timeout” value, this option is only connected to a computer directly to the printer and effective use of network printers Time is invalid.
7. Check the computer’s BIOS settings in the printer port is open. BIOS to use the printer port should be set to “Enable”, some printers do not support ECP port signal type of print should print port is set to “Normal, ECP EPP” mode.
8. Check your computer for viruses, if necessary, anti-virus with anti-virus software.
9. Check the printer driver is damaged. Right-click the printer icon available, select “Delete”, then double-click the “Add Printer”, re-install the printer driver.
10. Printer tray without paper or cardboard, printer toner cartridges, ribbons or toner cartridge is valid, if invalid, can not print.
No.9, printer paper jam or not to go
The most common failure is the printer jams. This failure occurs when the indicator lights on the control panel, send a warning signal to the host. This failure occurs for many reasons, such as paper output path with debris, feed roller and other components turn failure, does not feed paper tray, sensor failure, etc., to troubleshoot the method is very simple, just open the cover Remove the jammed paper can, but be careful, must feed the direction of the pickup, and must not turn any knob the opposite direction.
If regular paper jam, check into the paper path, remove the output path of the debris, the front edge of the paper to just above the metal plate. Check out the spring roller for wear or loose, the pressure is not enough, that is not the paper into the machine. The paper roll wear, and sometimes can not be replaced, the wound rubber band approach can be used for emergency treatment. After Dell inspiron mini 10 battery winding the rubber band, twist increases the friction of paper, can feed back to normal. In addition, the loading tray is not installed properly, the paper quality is not good (too thin, too thick, wet), can also cause paper jams or can not take the fault.
No.10, printed characters appeared random
Whether it is dot matrix printer, inkjet printer or laser printer to print garbage phenomenon, mostly due to print damage or host microcontroller interface circuit damage caused by the actual inspection found damage to the printer interface circuit failure is more common, due to the interface circuit micro power supply, once the interfaces have instant high-voltage static electric plug, it is easy to breakdown interface chips, usually as long as the replacement of the interface chip, such failure can be ruled out. In addition, the printer fonts will not load properly for this phenomenon.
