If the paper you printed has yellow lines, it is likely that the printer ink cartridges need to be cleaned or replaced. Over time, ink can build up in the nozzles or printhead of the printer, causing the ink to not dispense evenly. This can result in lines or streaks of a different color, such as yellow.
Here are a few things you can try to fix the issue:
1.Run a cleaning cycle: Most printers have a cleaning function that you can access through the printer settings. Running a cleaning cycle can help remove any built-up ink from the printhead or nozzles.
2.Check the ink cartridges: Make sure that the ink cartridges are properly installed and have enough ink. If the ink cartridges are running low or are empty, replace them with new ones.
3.Check the paper: Sometimes, the paper you use can affect the print quality. Make sure you are using the correct type of paper for your printer and that it is not too old or damaged.
4.Check the printer settings: Make sure the printer settings are set to the correct paper size and quality.
If these steps do not resolve the issue, you may need to contact the printer manufacturer or a technician for further assistance.
