Could be a “buggy” graphics card. If no image appearing at all, driver might be corrupted after an auto-update. - Reboot Windows in Safe Mode or roll back or delete the driver for graphic card, If project device overheats, it will trigger an auto-shutdown. - See if the built-in cooling fan needs to be replaced., Often occur in LCD screens, whether TV or computer monitor. - Determine if pixels are dead or stuck. There are steps you can try if pixels are stuck., Distortion on screen image. Caused by improperly operating graphics card. - Make sure graphics card isn’t overheating. Make sure latest drivers update wasn’t corrupted. If so, roll back and reinstall update. Check OS/software for updates., Image is displaying incorrect color pattern, such as a strong tint. - It’s possible that one of the projector’s panels may have failed., Either the top or bottom half of the monitor screen is dimmed. - The backlight could be dead or dying, needs to be replaced., A visible change in brightness between cycles in the screen. - Usually occurs with an LCD (not known to occur with LED). Could either be very inexpensive panel with too much backlight or a dying Cold Cathode Fluorescent Lamp (CCFL)., Something in the image has twisted, changed, or is exaggerated, making it appear differently from the way it really is. - Could be caused by improper display setting in the OS or the video driver could be corrupted., Improper positioning of scatters in the image screen. - Check image resolutions, check if video driver is up to date. It could be a loose or defective video cable. Check refresh rate for any issues., Common in early generations of monitors. Shows burn-in or afterimage after an image has been repeatedly displayed in the same place for a long time. - Configure the OS display setting to turn off idle display off or protect them with an animated screensaver., An icon is too big on your desktop screen. - Could be either hardware or software related. In Windows, right-click to bring up the dialog menu. Select View from the drop-down menu. If it is set to Large Icons, select Small Icons., Printing vertical lines or dirty-looking or there are smudged lines running continuously down the page. - Could be the early warning sign of a low-ink cartridge if it is an ink-based printer. As for laser printers, it usually indicates a dirty or damaged fuser unit. Replace new ink for ink-based printer, replace new fuser unit for laser printer., Laser printer is producing faded or blank pages, or prints lighter than the fresh text and images on the page. - The most likely culprit is either the imaging drum unit or the fuser unit. Humidity and using the incorrect paper type can both cause ghosting. Check if the ink is low. Check the laser printer’s toner density settings. If using an inkjet printer, the inkjet print head may be clogged., When the printout paper looks smudged or the ink easily rubs off by your finger, the toner isn’t fused to the paper. - The fuser may be improperly fusing the toner to the paper. Make sure you are using a suitable paper type for a laser printer. Check that the fuser is reaching the correct temperature by testing on lighter-weight paper. Or, the toner may need replacing., Laser printers work by printing the paper through a number of rollers. Some rollers are responsible for heat and pressure roller of the fuser assembly. Other rollers move the paper from the paper tray to the output tray. - If you’re getting creased papers, the rollers could be a reason for this. If the creases are noticeable, test with a different type of paper. Cotton bond paper tends to cause this issue. There is no known hardware solution to this. It’s dependent on the type of paper chosen., Printer not feeding - Check that the printer’s tray configuration is set to use the correct tray. Check for any misaligned paper in the paper tray. Check that you are using the correct paper weight and paper type. If the paper tray has adjustable guides, make sure it isn’t holding the paper too tightly, Paper jam - When paper is stuck at the entrance to the printer. It’s always a good idea to follow the manufacturer's jam removal procedures because removing a paper jam can easily cause damage to the printer’s jam sensors or feed sensors. If the printer is reporting paper jams, but there isn’t any paper there, you’ll need either take the printer to the repair center. Or…. get yourself a new printer., No printer connectivity - Check all cables, ports, and power. If the printer’s display is still showing no connectivity, you may need to navigate its menu system to view its connectivity status. It may be a network side issue., Garbled characters on paper - Misaligned print out is commonly caused by corrupted or improper driver settings. First, try rebooting the printer. Then, if needed, check the driver setting., Vertical lines on paper - Check toner to ensure nothing is clogged, which could prevent the proper dispersion of toner on the drum. Try shaking the toner cartridge to unclog it., Backed up print queue - Could be overflowing or corrupting due to lack of disk space, too many print jobs, or it could be something else. Check the printer menu for any remaining pending print jobs, delete all of them, and try again., Low memory errors - Insufficient memory space in printer due to overflowing buffer. Try reducing the printing resolution, printing smaller graphics, or reducing the complexity of the printing job. Or, if the laser printer has a RAM access port, add more RAM., Printer access denied - Most often, it has something to do with the OS printer sharing permissions. Check the host system in the security setting of the printer properties and make sure the user account is allowed to use print sharing., Printer will NOT print - Make sure the printer is on, check connectivity, look for an error message on the printer display, make sure there is paper in the tray, and ensure that the computer is online., Multiple failed print jobs - Check the printer status in the OS to see if there any remaining print jobs. Delete them and try again., Unable to install printer - Check the group policy in OS to allow non-administrators to install driver for printers., Printing blank pages - Run printer self-diagnostic to print the test page. It will help root out the problem. It could be that the color is mismatched in the printer’s settings. Double check the app to ensure it wasn’t improperly set to grayscale and double check the color ink/toner levels., No image on printer display - The printer might be worn out from decades of use. Try rebooting the device by unplugging it for few minutes. If the screen still isn’t showing an image, it is probably a display screen malfunction. Take the printer to the repair center., Slow transfer speeds - There may be multiple open, unused programs that are trying to use the Internet. The number of programs connected to the Internet divide the Internet connection’s maximum speed., Low RF signal - The computer’s WiFi might be out of range from the access point. Either relocate the computer or access point to bring it closer or swap out the access point’s antennas with higher-gain antennas to improve the range.,
